2 System overview 2.1
General description NT
InteliCompact (also IC-NT) Family controllers are comprehensive gen-set controllers for single and multiple generating sets operating in stand-by or parallel modes. A modular construction allows upgrades to different levels of complexity in order to provide the best solution for various customer applications. The controllers are equipped with a powerful graphic display showing icons, symbols and bar graphs for intuitive operation, which, together with its high level of functionality, sets new standards in Gen-set controls. The key features are:
2.2
Easy-to-use operation and installation. The factory default configuration covers most applications Various customizations are possible thanks to its configurability Excellent remote communication capabilities High level of support for EFI engines (most world producers) High reliability
Configurability and monitoring
One of the key features of the controller is the system’s high level of adaptability to the needs of each individual application and wide possibilities for monitoring. This can be achieved by configuring and using the powerful ComAp PC/mobile tools. Supported configuration and monitoring tools: -
LiteEdit – complete configuration and single gen-set monitoring InteliMonitor – multiple site monitoring and setpoint setting WinScope – special graphical monitoring software WebSupervisor – web-based system for monitoring and controlling o WebSupervisor mobile – supporting application for smartphones
NOTE: Use the LiteEdit PC software to read, view and modify configuration from the controller or disk and write the new configuration to the controller or disk. NT
The firmware of InteliCompact contains a large number of binary inputs and outputs needed for all necessary functions available. However, not all functions are required at the same time on the same gen-set and also the controller hardware does not have so many input and output terminals. One of the main tasks of the configuration is mapping of “logical” firmware inputs and outputs to the “physical” hardware inputs and outputs. Configuration parts: 1. Mapping of logical binary inputs (functions) or assigning alarms to physical binary input terminals 2. Mapping of logical binary outputs (functions) to physical binary output terminals 3. Assigning sensor characteristics and alarms to analog inputs 4. Assigning control values and output characteristics to analog outputs 5. Selection of peripheral modules which are connected to the controller and doing the same as the above for them 6. Selection of ECU type if an ECU is connected 7. Changing the language of the controller interface NT

PRINCIPLE OF BINARY INPUTS AND OUTPUTS CONFIGURATION The controller is shipped with a default configuration, which should be suitable for most standard applications. This default configuration can be changed only by using a PC with the LiteEdit software. See LiteEdit documentation for details. NOTE: You need one of communication modules to connect the controller to a PC with LiteEdit. There is a special easy removable service module for cases when no communication module is permanently attached. Once the configuration is modified, it can be saved to a file for later usage with another controller or for backup purposes. The file is called archive and has the file extension .aic. An archive contains a full image of the controller at the time of saving (if the controller is online for the PC) except the firmware. Besides configuration it also contains current adjustment of all setpoints, all measured values, a copy of the history log and a copy of the alarm list. The archive can be simply used for cloning controllers, i.e. preparing controllers with identical configuration and settings.

True RMS measurement
This controller measures AC values based on the True RMS principle. This principle corresponds exactly to the physical definition of alternating voltage and current effective values. Under normal circumstances the mains voltage and current should have a pure sinusoidal waveform. However, some nonlinear elements connected to the mains produce harmonic waveforms with frequencies of multiples of the basic mains frequency and this may result in deformation of the voltage and/or current waveforms. The True RMS measurement gives accurate readings of effective values not only for pure sinusoidal waveforms, but also for deformed waveforms. NOTE: The harmonic deformation causes that the Power Factor of a generator working parallel with the mains cannot reach values in a certain range around the PF 1.00. The higher the deformation, the wider the power factor dead range. If the requested power factor is adjusted inside the dead range, the controller cannot reach the requested value because of this fact.

For field type terminals: Use only diameter 2.0–0.5 mm (12–26 AWG) conductor, rated for 75 °C minimum. For Mains (Bus) Voltage and Generator Voltage terminals Use only diameter 2.0-0.5 mm (12–26 AWG) conductor, rated for 90 °C minimum. Use copper conductors only.
Grounding 2
The shortest possible piece of wire should be used for controller grounding. Use cable min. 2.5 mm . A brass M4x10 screw with star washer securing ring type grounding terminal shall be used. The negative “-” battery terminal must be properly grounded. Switchboard and engine must be grounded at a common point. Use as short a cable as possible to the grounding point.
3.7
Power supply
To ensure proper function: Use min. power supply cable of 1.5 mm

The maximum continuous DC power supply voltage is 36 V DC. The maximum allowable power supply voltage is 39 V DC. The InteliCompact’s power supply terminals are protected against large pulse power disturbances. When there is a potential risk of the controller being subjected to conditions outside its capabilities, an outside protection device should be used. It is necessary to ensure that potential difference between the generator current COM terminal and the battery “-” terminal is maximum ± 2 V. Therefore, it is strongly recommended to interconnect these two terminals together. HINT: NT The InteliCompact controller should be grounded properly in order to protect against lighting strikes!! The maximum allowable current through the controller’s negative terminal is 4A (this is dependent on binary output load). NT

For connection with a 12 V DC power supply, the InteliCompact includes internal capacitors that allow the controller to continue operation during cranking if the battery voltage dip occurs. If the battery voltage is 10 V before the dip and it recovers to 7 V within 100 ms the controller continues operating. During this voltage dip, the controller screen backlight may turn on and off but the controller keeps operating. It is possible to further support the controller by connecting the external capacitor and separating diode or I-LBA module:
The capacitor size depends on the required time. It shall be approximately in the thousands of microfarads. The capacitor size should be 5000 microfarad to withstand a 150 ms voltage dip under the following conditions: Voltage before dip is 12 V, after 150 ms the voltage recovers to the min. allowed voltage, i.e. 8 V. HINT: Before the battery is discharged the message "Low BackupBatt" appears. Or by connecting a special I-LBA Low Battery Adaptor module:
The I-LBA module ensures a min. 350 ms voltage dip under following conditions:
Communication and extension plug-in modules are connected. Voltage before dip is 12 V and after 350 ms the voltage recovers to the min. allowed voltage 5 V. The I-LBA enables controller operation from 5 V DC (for 10 to 30 seconds). The wiring resistance from the battery should be up to 0.1 Ω for proper function of the I-LBA.
HINT: I-LBA may not eliminate voltage drop when used with the low temperature (-40 °C) version of the controller and the display heating element is on (below 5 °C). The current drain of the heating element exhausts LBA capacitors very fast.

Power supply fusing
A one-amp fuse should be connected in line with the battery positive terminal to the controller and modules. These items should never be connected directly to the starting battery. Fuse value and type depends on the number of connected devices and wire length. The recommended fuse type (not fast) is T1A due to internal capacitors charging during power up.

Voltage and current inputs
WARNING! Risk of personal injury due to electric shock when manipulating voltage terminals under voltage! Be sure the terminals are not under voltage before touching them. WARNING! Do not open the secondary circuit of current transformers when the primary circuit is closed!!! Open the primary circuit first! 2

NOTE: IT IS NECESSARY TO ENSURE THAT THE POTENTIAL DIFFERENCE BETWEEN THE GENERATOR CURRENT COM TERMINAL AND THE BATTERY “-” TERMINAL IS MAXIMUM ± 2V. THEREFORE, IT IS STRONGLY RECOMMENDED TO INTERCONNECT THESE TWO TERMINALS TOGETHER. CAUTION: NT W HEN YOU ARE USING INTELICOMPACT HW VERSION 1.3 OR NEWER IT IS NECESSARY TO UPGRADE THE FIRMWARE TO IC-NT-1.4.3 OR NEWER. NT
Since HW version 1.3 the InteliCompact measures current with reversed polarity. It is not recommended to switch wiring at the current transformer side. To fix this error use FW IC-NT-1.4.3 or newer.

Speed measurement
The engine speed can be measured either from the generator frequency or from a magnetic pickup. If an EFI engine is configured, the engine speed is obtained from the ECU.
3.9.1
Pickup
A magnetic speed sensor (pickup) is the most common method of engine speed measurement. To use this method, mount the pickup opposite to the engine flywheel, connect the cable to the controller as shown on the picture below and adjust the setpoint Gear Teeth according to the number of teeth on the flywheel.

RPM is measured from generator frequency. D+ and W terminals from the charging alternator can be used as additional signals for detection of running engine.
3.9.3
Additional running engine indication
It is helpful to have information other than speed (RPM), whether the engine is rotating or not, especially if RPM is measured from the generator frequency instead of magnetic pickup. The generator frequency measurement can be unreliable at very low speeds and/or may have a delayed reaction to sudden and big changes (i.e. in the moment that the engine has just started…). The following conditions are evaluated as additional running engine indication:
Voltage on the D+ input is higher than 80% of battery voltage. Connect this input to the D+ (L) terminal of the charging alternator and enable the D+ function by the setpoint D+ Function. If D+ terminal is not available, leave the input unconnected and disable the function. The pickup is not used and frequency is detected on the pickup input. Connect the pickup input to the W terminal of the charging alternator if you do not use pickup and the W terminal is available. If not, leave the input unconnected.
NOTE: The starter cut-off frequency has to be adjusted by the setpoint Start W Freq. If you know the charging alternator nominal frequency, adjust the setpoint to the frequency obtained from following equation: (
)
If you do not know the charging alternator nominal frequency, follow this procedure: 1) Make sure that the starting accumulator is fully charged. 2) Close a fuel valve manually to disable the engine from being started.

3) Connect a PC with LiteEdit to the controller and display "Values" window, group "Engine", value W-TerminalFreq. 4) Select MAN mode and press the Start button to crank the gen-set. Make a note about the W terminal frequency while the gen-set is cranking. 5) Press the Stop button to stop cranking. 6) Adjust the setpoint Start W Freq to a value twice that which you measured during cranking.
Oil pressure > Starting Oil P setpoint. The oil pressure is evaluated from the analog input 1 or from the ECU if an ECU is configured. At least one phase of generator voltage is >20% of nominal voltage.
These signals are used during start for powering down the starter motor even if still no RPM is measured and also during stop in order to evaluate if the engine is really stopped.

NOTE: The fail sensor alarm is issued if the measured resistance is smaller than one half of the first (lowest) point of the sensor curve characteristic or is greater than 112.5% of the last (highest) point of the sensor curve characteristic. NOTE: Analog inputs are typically used for: Oil Pressure, Water Temperature and Fuel Level. All of these parameters are connected with relevant protections.

3.13 Circuit breakers There are two power switches controlled by the controller:
The generator circuit breaker or contactor – GCB The Mains circuit breaker or contactor – MCB (SPtM application only)
It is possible to use either a motorized circuit breaker or contactor. Below is a list of available control outputs that should fit all types of contactors or breakers. The following rules must be kept to when designing the wiring of power switches:
The control outputs must be configured and wiring of the power switches must be provided in such a way, that the controller has full control over the breakers – i.e. the controller can open and close the breaker at any time.
NT
InteliCompact , SW version 1.4 InteliCompact-NT-1.4-Reference Guide-r3.pdf, ©ComAp – March 2013
24
The breaker must respond within max. 2 seconds to a close and open command. Special attention should be paid to opening of motorized circuit breakers, as it could take more than 2 seconds on some types. In such cases it is necessary to use an undervoltage coil for fast opening. The breaker feedback functions must be configured onto some binary inputs and the signals from the breakers must be connected to it and provide reliable information about the breaker position.
3.13.1
Breaker control outputs
An output for control of a contactor. Its state represents the breaker position Close/open requested by the controller. The breaker must react within 2 seconds to a close or open command, otherwise an alarm is issued. ON coil
An output giving a 2 second pulse in the moment the breaker has to be closed. The output is intended for control of close coils of circuit breakers.
OFF coil
An output giving a pulse in the moment the breaker has to be opened. The pulse lasts until the feedback deactivates, but at least for 2 seconds. The output is intended for control of open coils of circuit breakers.
UV coil
The output is active the whole time the gen-set is running (GCB, not in idle or cooling) or the controller is switched on (MCB). The output is deactivated for at least 2 seconds in the moment the breaker has to be switched off. The output is intended for control of undervoltage coils of circuit breakers.

MCB special requirements SPtM only
1. If a contactor is used on the MCB position, it is recommended that the wiring be provided in such a way that the contactor will be normally closed and will open if the MCB Close/Open closes. This behaviour is called “negative logic” and can be adjusted by the setpoint MCB Logic. The negative logic will prevent accidental opening of the MCB when the controller is switched off. 2. If a contactor is used on the MCB position, it will open itself immediately after the mains have failed, because it will lose power for the coil. That is why the following adjustment is necessary to prevent triggering the MCB fail alarm: MCB Opens On = MAINSFAIL, Mains V Del ≤ 1. 3. If a 230 V motor driven circuit breaker is used on the MCB position and an undervoltage coil is not fitted, it is not possible to open the breaker after the mains have failed, because there is no

power for the motor drive until the gen-set is started and providing voltage. Adjusting the setpoint MCB Opens On = GEN RUN will prevent triggering the MCB fail alarm.
3.14 AVR interface The AVR output is used to control the voltage or power factor of the generator via the remote voltage adjust input provided by the AVR. The output from the controller is a 5V PWM that is designed to be used together with the IG-AVRi module. The AVRi module provides galvanic separation of the controller from the generator and PWM to voltage conversion, which is needed for most AVRs. The output from the IG-AVRi module is available as positive, negative or symmetric. The output voltage range is adjustable by a trimmer located on the module. The initial level of the AVR output is adjustable by the setpoint AVRi Bias.
3.14.1
IG-AVRi
Automatic voltage Regulator interface is used for volt/PF control adjustment through galvanic separated inputs and outputs. CAUTION: Refer each time to the corresponding AVR manual before connecting the interface. IG-AVRi-TRANS (AC power supply for AVRi) has to be supplied from gen-set voltage. AVRi output can be connected as symmetrical: OUT1-OUT2 or unsymmetrical OUT1-GND or OUT2GND. - The potentiometer on the AVRi defines maximum OUT1, OUT2 voltage range. - Use symmetrical (OUT1, OUT2) AVRi output to connect the AVRi to AVR auxiliary voltage input. - Use unsymmetrical output if an external AVR potentiometer has to be replaced with AVRi. - AVRi output voltage should change the generator voltage typically in the range ± 10% of the Nominal voltage. NOTE: IG-AVRi is not included in the standard package with the controller. IG-AVRi TRANS/LV is a power supply unit for IG-AVRi; it is not included with the IG-AVRi package.

The Vext input (connector CN1 – terminals 10 and 11) permits analog remote control of output voltage with a programmable variation range of up to ±10% (parameter 16, by default the setting is ±5%) with respect to the value set. If you want to use continuous voltage, it will be effective if it is in the range between 0 V and +2.5 V. The input tolerates voltages from -5 V to +5 V, but for values exceeding the limits of 0 V / +2.5 V (or in the event of disconnection) it is automatically disabled and the voltage adjustment goes back to the value set through the trimmer (if enabled) or through parameter 19 (as shown on the picture). Changing the DSR parameters requires a PC with dedicated software and a DI1-DSR unit! DSR automatically detects the presence of a transformer for parallel operation (if used it works with droop, if not used then it works isochronous). NT

3.15 Speed governor interface The speed governor output is used to control the speed or the power of the engine via the remote speed controlling input provided by the speed governor. The output from the controller can work in the following modes:
voltage mode 0 to 10 V voltage mode 0 to 10 V with serial 10k resistor 5 V PWM mode
NOTE: The PWM mode is designed and optimized for Caterpillar governors. The jumpers for speed governor output mode are shown on the picture below.
The initial level of the governor output is adjustable by the setpoint Speed Gov Bias and the characteristic (positive or negative) can be selected by the setpoint Speed Gov Char. The active range of the output can be adapted to the governor input range by setpoints SpeedGovLowLim and SpeedGovHiLim. NOTE: Some governors may evaluate input voltage out of the allowed range as a faulty condition and their functioning may be blocked.

3.16 CAN bus wiring The wiring of the CAN bus communication should be provided in such a way that the following rules are observed:
The maximum length of the CAN bus depends on the communication speed. For a speed of 250 kbps, which is used on the CAN1 bus (extension modules, ECU) and CAN2 bus if it is switched to 32C mode, the maximum length is 200 m. If the CAN2 bus is switched to 8C mode the speed is 50 kbps and the maximum length is 800 m. The bus must be wired in linear form with termination resistors at both ends. No nodes are allowed except on the controller terminals. NOTE: A termination resistor at the CAN is already implemented on the PCB. For connecting, close the jumper near the appropriate CAN terminal.
Use a cable with following parameters: Cable type
Shielded twisted pair
Impedance
120 Ω
Propagation velocity
≥ 75% (delay ≤ 4.4 ns/m)
Wire crosscut
≥ 0.25 mm

CAN bus connection
The bus has to be terminated by 120 Ω resistors at both ends. External units can be connected on the CAN bus line in any order, but keeping a line arrangement (no tails, no star) is necessary. Standard maximum bus length is 200 m for 32C CAN BUS MODE and 900 m for 8C CAN BUS MODE. Shielded cable must be used. Shielding has to be connected to PE on one side (controller side). 1. For shorter distances (all network components within one room) – picture 1 Interconnect H and L; shielding connect to PE on controller side 2. For longer distances (connection between rooms within one building) – picture 2 Interconnect H, L, COM; shielding connect to PE at one point 3.

To insert the module, you must open the cover first (use a screwdriver to open) and then insert the module into the slot. Once you have inserted it, the module will snap under the plastic teeth. It is supposed to be installed permanently. Should you need to remove it, the safest way is to remove the entire back cover and then remove the module manually. Installing the IL-NT BIO8 module is similar to installing the RS 232 module. The difference is that module fits into the “extension module” slot and after installing the IL-NT BIO8 you do not put the small cover back.

NOTE: Current measuring input is intended to measure one phase (AC) current of mains and to limit Export/Import to/from mains to zero value during parallel to mains operation. This is the case of the SPtM application, so current input of the IC-NT CT-BIO7 module is useful for SPtM controllers only. To insert the module, you must open the cover first (use a screwdriver to open) and then insert the module into the slot. Once you have inserted it, the module will snap under the plastic teeth. It is supposed to be installed permanently. Should you need to remove it, the safest way is to remove the entire back cover and then remove the module manually. Installing the IC-NT CT-BIO7 module is similar to installing the RS 232 module. The difference is that module fits into the “extension module” slot and after installing the IC-NT CT-BIO7 you do not put the small cover back.
Technical details: NT IC-NT CT-BIO7 plugs into InteliCompact controller EXTENSION MODULE port. 7 dedicated pins of the plug-in card’s terminal can be configured as binary inputs or outputs. CURRENT MEASURING INPUT Number of inputs

3.20 EFI engines To meet requests for low fuel consumption, low emissions and high reliability, modern engines are electronically controlled by an "Engine Control Unit" (ECU). The ECU is fitted directly on the engine; it measures various engine parameters like speed, intake air flow, coolant temperature, etc. and controls various actuators like injectors, ignition, valves, etc. to achieve optimal operating conditions of the engine. Most of the ECUs also have a communication interface to the rest of the system (e.g. a vehicle, a genset, a pump, etc.) to provide engine operational data, alarm conditions and also to enable remote control. The most commonly used interface is the CAN bus with the SAE J1939 protocol or sometimes also the RS485 with the MODBUS protocol. The J1939 protocol was introduced by the SAE organization originally for the automotive industry but now is often used also for other engine applications. The J1939 specification is partially open, which means that each engine producer may have a slightly different implementation of the J1939 protocol. This is why each new ECU type obviously needs slight modification of the controller firmware to support the particular ECU. The IC-NT controller supports most of the J1939-based ECU types as well as Cummins Modbus ECU. New ECU types are added to the firmware as they appear in the field.
3.20.1
Differences between a classic and EFI-engine application
The main difference is less wiring, sensors and actuators in an EFI-engine application compared to a classic one. The typical wiring of an EFI-engine application shows that there are no analog sensors, no pickup and no governor. All this information is being communicated between the controller and the ECU via the communication bus.

4 Putting it into operation 4.1
Programming the configuration
The controller is delivered with a default configuration that should fit most standard applications. Nevertheless you may need to modify it because your application is different. Please refer to the LiteEdit manual or help file for information on using LiteEdit for changing the particular items of the configuration and writing the configuration to the controller.
CONFIGURATION WINDOW IN LITEEDIT
4.2
Programming the firmware
Although the controller is delivered with the latest firmware available at the moment of production, it may be necessary to upgrade the firmware in future. The process of programming the firmware involves the following steps: 1. First you need the requested firmware. Firmware of standard branch and major versions are distributed and installed together with the LiteEdit installation package. Release versions and branches are distributed as import packages that need to be imported into LiteEdit. 2. The latest installation and/or import packages are available for download at www.comap.cz. Please register to get access to the download page. Registration is free. 3. The import package is a file with the IWE extension. To perform the import, start LiteEdit, do not open any connections, go to Options -> Import firmware and select the appropriate file. 4. Create an online connection to the controller and save the archive for backup purposes. NOTE: It is not possible to update firmware when the connection is offline! 5. Go to the menu Controller -> Programming and cloning -> Programming, select the appropriate firmware and press the OK button. 6. The selected firmware will be programmed into your controller. NT
InteliCompact , SW version 1.4 InteliCompact-NT-1.4-Reference Guide-r3.pdf, ©ComAp – March 2013
68
NOTE: It is possible to program only firmware compatible with the currently attached controller. Other firmware is disabled and cannot be selected for programming. CAUTION! The configuration reverts to the default after firmware has been programmed. You must re-program the configuration if the default one is not appropriate for your application! CAUTION! Also some setpoints may have incorrect values after new firmware was programmed. Please check all setpoints after programming.
4.3
Programming a non-responsive controller
If the controller does not contain valid firmware, new firmware cannot be programmed in the standard way. This situation can occur if the connection between the PC and the controller was interrupted e.g. during a previous firmware upgrade. In such a case the controller has a blank display and does not communicate with the PC. The boot-jumper must be used to get valid firmware into the controller. 1. Disconnect the power supply from the controller, insert a communication module and close the boot-jumper.
BOOT-JUMPER ON IL-NT RS232 NOTE: See the communication modules chapter for information about boot-jumper position on other modules. 2. Connect the proper communication cable between the controller and PC. 3. Start LiteEdit and open an online connection according to the module used. Select controller address 1. Wait until the bottom line of LiteEdit shows a red line with the text "DDE server: Error". 4. Go to the menu Controller -> Programming and cloning -> Programming, select the appropriate firmware and press the OK button. 5. Follow the instructions in the message that appears and finally press the OK button. 6. Another message will appear when programming is finished. Follow the instructions given there.

Step-by-step guide
In the following you will find several steps which you should carry out when you are putting a gen-set into operation. It supposes that the switchboard wiring has been already checked. NOTE: This guide is not a handbook for a beginner, but it is focused on things specific for ComAp controllers and expects sufficient knowledge and skills in the field of generating sets! WARNING! Some parts of the generator, engine and switchboard may carry dangerous voltage which can cause injury or death when touched! WARNING! Rotating parts of the gen-set can catch hair or clothing and cause serious injury. 1. Disconnect the binary outputs from the controller before connecting the power supply. If you have an SPtM application, be sure that the MCB and GCB are protected against accidental switching when you are working in the switchboard. 2. Check the controller configuration according to the wiring diagram of the switchboard. If the configuration has been modified, write it to the controller 3. Write all setpoints from the default archive and then go through them and readjust all of them if it is necessary. Pay special attention to nominal values, overspeed, gear teeth, fuel solenoid and CT ratio. 4. Check all settings regarding speed sensing and additional running information, especially if you do not use a pickup for speed sensing. 5. Adjust bias setpoints for the governor and AVRi output to the recommended levels and adjust all delays for generator protections to high values to have enough time for making adjustments on a running gen-set. 6. Connect the binary outputs back. 7. Adjust all setpoints related to engine start and stabilization phase, then start the gen-set in MAN mode and then make fine readjustments. 8. Leave the gen-set running and adjust the governor and/or AVRi so that the gen-set will have a speed and voltage near to the nominal values. If it is not possible to achieve this by turning the trim on the AVRi and/or governor, you can also slightly change the bias setpoints. NOTE: The bias setpoints must not be near the limits for the particular output, because the regulation loops need sufficient reserve of the output range on both sides to work correctly. 9. Adjust all generator and engine protections according to your needs including the delays. 10. Adjust the setpoint Phase Window to 0. This adjustment will disable issuing of the GCB close command during synchronization, but the synchronization itself will be performed normally for the whole adjusted time. 11. Press the GCB button to start the synchronizing. Then, using a voltmeter connected directly over the contactor, check if the synchroscope indication on the controller screen matches the voltage. The voltage must be near to 0V when the synchroscope is in a 12 o'clock position and near to 2*Unominal when it is in a 6 o'clock position. Check all three phases.

6.3
Operating modes
Selecting the operating mode is done through MODE buttons on the front panel or by changing the Controller mode setpoint (from the front panel or remotely). NOTE: If this setpoint is configured as password-protected, the correct password must be entered prior to attempting to change the mode. NOTE: The mode cannot be changed if Access Lock input is active. The following binary inputs can be used to force one respective operating mode independent of the mode setpoint selection:
Remote OFF Remote MAN Remote AUT Remote TEST Rem TEST OnLd
If the respective input is active the controller will change the mode to the respective position according to the active input. If multiple inputs are active, the mode will be changed according to priorities of the inputs. The priorities match the order in the list above. If all inputs are deactivated, the mode will return to the original position given by the setpoint.
6.3.1
OFF
The GCB will be opened and the engine will be immediately stopped in this mode without unloading and cooling. After that the controller will stay in Not ready status and cannot be started any way. The MCB is closed permanently (MCB Opens On = GENRUN) or is open or closed according to whether the mains are present or not (MCB Opens On = MAINSFAIL). No AMF function will be performed. The buttons MCB, GCB, START, STOP including the appropriate binary inputs for external buttons are not active.
6.3.2
MAN
The engine can be started and stopped manually using the START and STOP buttons (or external buttons wired to the appropriate binary inputs) in MAN mode. When the engine is running, GCB can be closed to a dead bus or synchronizing can be started by the GCB button. Also MCB can be closed and opened manually using the MCB button, regardless of whether the mains are present or not. No auto start is performed. No reaction to the inputs Sys Start/Stop or Rem Start/Stop. A loaded engine in MAN mode will perform Load sharing and VAR sharing, but will not take place within the power management. NOTE: The breakers are internally locked to close two voltages against each other without synchronizing! The controller will automatically recognize if the breaker can be just closed or must be synchronized. CAUTION! The MCB can be opened manually in MAN mode. Accidental opening of the MCB will cause the object (load) to remain without power!!!
NT
InteliCompact , SW version 1.4 InteliCompact-NT-1.4-Reference Guide-r3.pdf, ©ComAp – March 2013
86
6.3.3
AUT
The engine is started and stopped by the binary input Rem Start/Stop (SPtM), by the Load demand auto start function (SPtM) or by the Power management (MINT). The buttons MCB, GCB, START, STOP including the appropriate binary inputs for external buttons are not active. The full start sequence up to the moment when the engine is loaded is automatic as well as unloading and the stop sequence. WARNING! If a red alarm is present and the gen-set is in AUT mode, it can start by itself after all red alarms become inactive and are acknowledged!!! To avoid this situation, adjust the setpoint Reset to MAN to the ENABLED position.
6.3.4
TEST SPtM only
The behaviour of the controller in TEST mode depends mainly on the setting of the ReturnFromTEST setpoint.
6.3.4.1 Automatic return Setpoint ReturnFromTEST = ENABLED. The gen-set will be started when the controller is put into TEST mode and will remain running unloaded. If a mains failure occurs, the MCB will be opened and after Transfer Del the GCB will be closed and the gen-set will supply the load. After the mains have recovered, the delay MainsReturnDel will count down and if it elapses and the mains are still ok, the controller will synchronize back to the mains, transfer the load back to the mains (the maximum time that both breakers are closed is determined by the BreakerOverlap setpoint) and the gen-set will remain running unloaded again until the mode is changed.
6.3.4.2 Manual return Setpoint ReturnFromTEST = DISABLED. The gen-set will be started when the controller is put to TEST mode and will remain running unloaded. If a mains failure occurs, the gen-set will take the load after it has started. The load can be transferred to the gen-set also manually:
If the GCB button is pressed, the controller will synchronize to the mains, transfer the load to the gen-set (the maximum time that both breakers are closed is determined by the BreakerOverlap setpoint) and then open the MCB. If the MCB button is pressed, the controller will open the MCB, then wait for Transfer Del and finally close the GCB.
When the load is supplied by the gen-set and the mains are healthy, pressing the MCB button will start reverse synchronizing and transfer the load back to the mains. The gen-set remains running until the mode is changed.
6.3.4.3 Test with load If the binary input Rem TEST OnLd is activated, the controller is switched to TEST mode (i.e. the genset will be started as described above), but once started the controller will automatically either
synchronize to the mains, transfer the load to the gen-set (the maximum time that both breakers are closed is determined by the BreakerOverlap setpoint) and then open the MCB
will make a switchover, i.e. open the MCB, wait for Transfer Del and close the GCB.

This depends on position of the binary input ForwSyncDisable. After the binary input Rem TEST OnLd has been deactivated, the controller goes back to the previous operation mode and its behaviour depends on that. In most cases it will be AUT mode and the controller will either stay supplying the load if the mains have failed, or will transfer the load back to the mains. NOTE: During the BreakerOverlap time, when both breakers are closed, the load is controlled either to the constant Baseload level (if the MCB has to be opened) or to zero level (if the GCB has to be opened).
6.3.4.4 Periodic exercises The output from the Exercise timer 1 is internally connected to the Remote TEST binary input to enable periodic testing of the gen-set. The controller must have AUT mode selected by the mode buttons and the other “mode forcing” binary inputs must not be active to ensure proper function of the exercise. NOTE: If a shutdown or other red alarm occurs while the load is supplied from the gen-set and the mains are healthy, the load is switched back to the mains.
6.4 6.4.1
Engine start Diesel engine
The setpoint Fuel Solenoid must be switched to the DIESEL position. 1. After the command for start is issued (pressing START button in MAN mode, auto start condition is fulfilled in AUT mode or controller is switched to TEST mode), the output Prestart is energized for time period given by the setpoint Prestart Time. 2. After the prestart has elapsed, the output Fuel Solenoid is energized and 0.5 after that the starter motor is activated by energizing the output Starter. 3. When one or more of following conditions are met, the prestart and starter of both outputs are de-energized: The engine speed exceeds the value of Starting RPM, or One of additional running indication signals becomes active. 4. The controller remains in the Starting phase until the engine speed exceeds the value of Starting RPM, after that it is considered as started and the Idle period will follow. 5. The maximum duration that the starter motor is energized is determined by the setpoint MaxCrank time. If the engine does not start within this period, the starter motor is deenergized and a pause with length determined by CrnkFail pause will follow. Prestart output remains active during the pause. After the pause has elapsed, the next start attempt is executed. The number of start attempts is given by the setpoint Crank Attempts. 6. Once the engine is started, the Idle period follows. The binary output Idle/Nominal remains inactive (as it was during the start). The idle period duration is adjusted by the setpoint Idle Time. 7. After the idle period has finished, the output Idle/Nominal is activated and the start-up sequence is finished. The stabilization phase follows.

After the command for start is issued (pressing START button in MAN mode, auto start condition is fulfilled in AUT mode or controller is switched to TEST mode), the output Prestart is energized for time period given by the setpoint Prestart Time. 2. After the prestart has elapsed, the starter motor is activated by energizing the output Starter. 3. When the engine speed exceeds 30RPM, the outputs Fuel Solenoid and Ignition are energized. 4. When the engine speed exceeds value of Starting RPM, the starter motor is de-energized, the engine is considered as started and the Idle period will follow. CAUTION! Additional running indication signals are not evaluated during the start of a gas engine. The Pickup must be used in any case! 5. The maximum duration the starter motor is energized is determined by the setpoint MaxCrank Time. If the engine does not start within this period, the starter motor and fuel solenoid are deenergized and a pause with a length determined by CrnkFail Pause will follow. Prestart output and ignition remain active during the pause. After the pause has elapsed, the next start attempt is executed. The number of start attempts is given by the setpoint Crank Attempts. 6. Once the engine is started, the Idle period follows. The binary output Idle/Nominal remains inactive (as it was during the start). The idle period duration is adjusted by the setpoint Idle Time. 7. After the idle period has finished, the output Idle/Nominal is activated and the start-up sequence is finished. The stabilization phase follows.

NOTE: The starting sequence will be interrupted at any time if a stop command comes. NOTE: The Underspeed protection starts to be evaluated 5 after the engine has been started (according to point 4). NOTE: When the engine is started (according to point 4) the delay given by the setpoint ProtectHoldOff will count down. After it has elapsed, the protections configured as engine running only will start to be evaluated. Continue to the stabilization phase.
6.5
Stabilization
When the start-up sequence is finished, the gen-set goes into the stabilization phase. There are two timers (setpoints) in this phase: 1. Min Stab Time starts to count down just after the idle period has finished. Generator voltage and frequency are not checked (respective protections are not evaluated) and the GCB cannot be closed even if the generator voltage and frequency are within limits. 2. Max Stab Time starts to count down just after the idle period has finished. Generator voltage and frequency are not checked (respective protections are not evaluated) but, opposite to the previous timer, the GCB can be closed (or synchronizing started) if generator voltage and frequency are within limits. In situations where the GCB is closed automatically (AUT, TEST modes), the closing of GCB or starting of synchronization will occur in the first moment when the generator voltage and frequency will get into limits and the Min Stab Time has already elapsed. In the event that the generator voltage or frequency are not within limits within the Max Stab Time period, the appropriate protection(s) will be activated and the gen-set will be cooled down and stopped. NOTE: The limits for the generator voltage and frequency are given by setpoints in the Gener protect group. NOTE: The value of the Min Stab Time setpoint must be lower than the value of Max Stab Time setpoint. Continue to the connecting to the load phase.
6.6
Connecting to the load
When the stabilization phase is finished, the gen-set can be connected to the load. The command for connecting the gen-set to the load is issued either automatically (AUT, TEST modes) or manually by pressing the GCB button. The following conditions must be valid:
The gen-set is running and the Min Stab Time timer has elapsed. The gen-set voltage and frequency are within limits.
NOTE:
NT
InteliCompact , SW version 1.4 InteliCompact-NT-1.4-Reference Guide-r3.pdf, ©ComAp – March 2013

The governor and AVR must be adjusted properly to achieve these limits as the controller does not perform any regulation and the regulation outputs have constant values given by the AVRi Bias and Speed Gov Bias setpoints. There are two ways to connect the gen-set to the load (bus bar). This depends on the state of MCB feedback and on the measured mains/bus voltage.
6.6.1
Connecting to dead bus
SPtM: if the MCB is open, the bus bar is considered as voltage-free and the GCB is closed without synchronizing. MINT: the measured bus voltage is also taken in account and it must be below 2% of the nominal bus voltage together with the open MCB to close the GCB without synchronizing. NOTE: If the group of gen-sets is activated and multiple gen-sets have to start simultaneously and connect to the empty bus bar, there is an internal logic to prevent closing of more GCBs to the bus bar at the same moment without synchronizing. One of the gen-sets will close the GCB, the others will wait and then they will synchronize to the first one. NOTE: There also is a protection of “Bus power loss sensing”. The “Bus Measure Error” is detected in MINT application when the voltage on the controller’s bus terminals is out of limits 20 seconds after: a) GCB (own) was closed in MAN or AUT mode b) MCB (feedback) was closed in AUT mode c) Any other GCB in power management group (on CAN bus) was closed. The alarm is activated after 20s. However, the GCB (own) closing is blocked immediately for safety reasons. This protection can avoid e.g. potential direct closing of GCB while the controller’s bus conductor are unintentionally unplugged from the terminals.
6.6.2
Synchronizing
SPtM: If the MCB is closed, the bus bar is considered to have identical voltage as measured on the mains. If the mains voltage/frequency is within limits, the gen-set is first synchronized with the mains and then the GCB is closed. MINT: If the measured bus voltage is within limits, the gen-set is first synchronized with the bus and then the GCB is closed. The synchronizing consists of voltage matching and frequency/angle matching. The maximum duration of synchronizing is given by the setpoint Sync Timeout. If the synchronizing is not successful within this period of time, the Sync Timeout alarm will be issued. NOTE: The synchronization will be interrupted automatically if any of the necessary conditions disappear during the synchronization process. When the controller starts to synchronize (the event will change to “Synchro”) and the Main Measuring screen is displayed, it will be automatically change to the Synchroscope screen for the entire duration of synchronization. After synchronization the Synchroscope screen is automatically changed back to the Main Measuring screen.

It is also possible to change screens manually (arrows Up and Down) after displaying the Synchroscope screen. In this case there is no automatic return to the Main Measuring screen after synchronization is finished.
6.6.2.1 Voltage matching The gen-set voltage is regulated to match the mains/bus voltage with tolerance given by the setpoint Voltage Window. The regulation is adjusted by the setpoints Voltage Gain and Voltage Int.
6.6.2.2 Frequency/angle matching The gen-set frequency is regulated to match the mains/bus frequency first. The frequency regulation loop is active (setpoints Freq Gain and Freq Int). Once the frequency is matched, the regulation loop is switched to match the angle (setpoint Angle Gain). When the angle is matched with tolerance +/Phase Window for a time given by the setpoint Dwell Time and the voltage is matched too, then the GCB is closed. NOTE: The GCB close command will be not issued if the Phase Window setpoint is set to 0. Synchronizing will continue until the Sync Timeout alarm occurs or the GCB is closed externally. NOTE: The matching loops will continue to run even if the GCB close command has been already issued until the controller receives GCB feedback or a GCB fail alarm occurs. After the feedback has been received, the control loops are switched to load and power factor loops or load and power factor sharing respectively.
6.7
Parallel to mains operation – SPtM SPtM only
After the gen-set has been synchronized to the mains, the parallel to mains operation follows. It consists of the following phases:
6.7.1
Ramping the power up
The first phase of the PTM operation is ramping the gen-set up to the requested power level. The speed of the ramp is given by the setpoint Load Ramp. The setpoint adjusts the ramp time for a change from 0% to 100% of nominal power.
6.7.2
Load control
The load is maintained at the constant level given by the setpoint Baseload. Regulation adjustment setpoints are available in the Sync/load control group. NOTE: In every moment when the requested load (e.g. baseload setpoint) changes, the ramp described in the chapter above will also take place.
6.7.3
Power factor control
The power factor is regulated to a constant value given by the setpoint Base PF. PF regulation loop is active. Regulation adjustment setpoints are available in the Volt/PF control group.

6.7.4
Object load dependent auto start
The gen-set can start and stop automatically according to the object load. To enable this function, the setpoint PeakAutS/S del must not be set to 0 (OFF). An automatic start will occur if the object exceeds the limit given by the setpoint PeakLevelStart and remains exceeded for a period longer than PeakAutS/S del. If the object load drops below PeakLevelStop, the gen-set will be stopped with the same delay as during start. The gen-set load is controlled according to the selected mode (see above). NOTE: The gen-set will continue to run if the binary input Rem Start/Stop is active.
6.7.5
Ramping the power down
When a stop command is received – e.g. the binary input Sys Start/Stop is deactivated or the STOP button is pressed – the gen-set load is ramped down before opening the GCB. The ramp speed is given by the setpoint Load Ramp, the end level is given by GCB Open Level and the timeout for finishing the ramping without reaching the open level is given by GCB open Del. When the GCB button is pressed, the gen-set load is ramped down before opening the GCB as well. But after the GCB has been opened, the gen-set remains running until a stop command comes or the GCB is pressed again to reclose the GCB. Continue to the cool down and stop phase.
6.7.6
Peak load shaving
Load [kW]
The gen-set can start and stop automatically according to the object load. An automatic start will occur if the object load exceeds a given upper limit (PeakLevelStart) and remains exceeded for a given period of time (PeakAutS/S Del). If the object load drops below a given lower limit (PeakLevelStop), the gen-set will be stopped with the same delay period experienced during start.

If the MCB is closed (MCB feedback is present) and the gen-set has been synchronized to the bus bar, the parallel to mains operation will follow. It consists of the following phases:
6.8.1
Ramping the power up
The first phase of the PTM operation is the ramping of the gen-set up to the desired power level derived from the system baseload or up to the load given by load sharing with other gen-sets connected to the bus bar. The speed of the ramp is given by the setpoint Load Ramp. The setpoint adjusts the ramp time for a change from 0% to 100% of nominal power.
6.8.2
Load control modes
There are two load control modes – system baseload and load sharing – which are selected by the setpoint #SysLdCtrl PtM. See the setpoint description for more information. If system baseload mode is selected, the Load regulation loop is active to maintain the load at the requested level which is derived from the system baseload. Each running gen-set takes a relatively equal part of the system baseload. In load sharing mode, the loop LS (load sharing) is active to maintain the load at the same relative level as the other loaded gen-sets in the group. The behaviour in this case is identical to multiple island mode. NOTE: The process of determining which gen-sets shall run is described in the power management chapter.
6.8.3
Power factor control
In system baseload mode the power factor is regulated to a constant value given by the setpoint #SysPwrFactor. The PF regulation loop is active. In load sharing mode, also power factor sharing is active to keep the power factor of all loaded gen-sets at an equal level. Regulation adjustment setpoints are available in the Volt/PF control group.
6.8.4
Ramping the power down
When a stop command is received – e.g. power management or binary input Sys Start/Stop is deactivated or the STOP button is pressed – the gen-set load is ramped down before opening the GCB. The ramp speed is given by the setpoint Load Ramp, the end level is given by GCB Open Level and the timeout for finishing the ramping without reaching the open level is given by GCB Open Del. When the GCB button is pressed, the gen-set load is ramped down before opening the GCB as well. But after the GCB has been opened, the gen-set remains running until a stop command comes or the GCB is pressed again to reclose the GCB. Continue to the cool down and stop phase.
6.9
Island operation – SPtM SPtM only
A situation where the MCB is open and the load is supplied from the gen-set is called Island operation. This situation will occur in the following cases: 1. The GCB has been closed to a dead bus bar, or 2. The gen-set was running parallel to the mains and the MCB has been opened. Neither voltage nor a frequency regulation loop is active. Keeping voltage and frequency at rated values is the task of AVR and the governor.

When a stop command is received – e.g. the binary input Sys Start/Stop is deactivated or the STOP button is pressed – the GCB will be opened and the gen-set will go to cool down phase. NOTE: When using the GCB button in MAN mode, the gen-set will not go to cool down and stop.
6.9.1
Island to PtM transfers SPtM only
If the mains are OK, the gen-set can be transferred back to the parallel to mains operation. The transfer can be done as no-break transfer (Reverse synchronizing) or break transfer (Changeover). Which of these kinds will be performed depends on the binary input RevSyncDisable. In AUT mode or TEST mode with automatic return, the reverse synchronizing or changeover is started automatically after the mains have been restored and remain healthy for a period given by the setpoint MainsReturnDel. Reverse synchronizing can be started manually by pressing MCB button in MAN mode.
6.9.1.1 Reverse synchronizing The reverse synchronizing process is identical to Forward synchronizing, but MCB is closed instead of GCB. In the event that the reverse synchronizing is not successful, RevSyncTimeout alarm is issued and the gen-set continues in island operation. After the alarm has been reset, the gen-set can try to perform reverse synchronizing again.
6.9.1.2 Changeover The changeover is performed if the reverse synchronizing is disabled with the RevSyncDisable binary input. The GCB is opened first and after a time period of Transfer Del the MCB is closed.
6.10 Island operation – MINT MINT only This chapter describes the situation where multiple gen-sets are running parallel to each other but not with mains. This situation will occur either when: 1. The common bus bar is dead due to opened MCB or there are no mains at all and the group of gen-sets has been activated, or 2. The group was running parallel to mains and the MCB has been opened. NOTE: The controller in MINT application does not control the MCB! Only the MCB position is evaluated from the binary input MCB Feedback and the position is the basic source of information for switching between island and parallel to mains operation. If the bus bar is empty, the first gen-set will close its GCB without synchronizing. Following gen-sets will synchronize to the already energized bus bar. In the event that multiple gen-sets start simultaneously and the bus bar is empty, the system will prevent closing of multiple GCBs to the bus bar without synchronizing. Instead of this, one of the gen-sets will close the GCB and energize the bus bar and the others will wait and then synchronize to the bus bar. When a stop command is received, e.g. from the power management or binary input Sys Start/Stop is deactivated or the STOP button is pressed, the GCB will be opened and the gen-set will go to cool down phase. NOTE: Using the GCB button in MAN mode the gen-set will not go to cool down and stop. NT

Continue to the cool down and stop phase.
6.11 Power management MINT only The power management is related to MINT application only. Power management is the process of automatic starts and stops of gen-sets within the group, depending on current load, state of the gensets and other conditions.
6.11.1
The concept
The power management is based on the load of the gen-sets, i.e. next gen-set will start when the load of the group raises above certain level. A next gen-set will stop, when the load drops down below a certain level. The process of determining of starts and stops is done in each controller; there is no "master" in the system. Each of the controllers can be switched off without influencing the complete system (except the situation when the respective gen-set will be not available...) The load of the group is evaluated as so called reserve. The reserve is calculated as difference between actual and nominal load of running gen-sets. The reserve can be calculated as absolute (in kW) or relative (in %). Use the setpoint #PowerMgmt Mode to set the the calculation method. NOTE: Power management based on relative reserves perfectly fits for applications, where the load portions connected to the group at once are much lower than the gen-set capacity. This mode helps to achieve maximal lifetime of the gen-sets, as they can be operated within optimal load range. The maximal size of the load connected at once depends on number of actually working gen-sets. The more gen-sets are connected to the busbar, the bigger a load portion can be connected at once. Power management based on absolute reserves can be successfully used also for cases where the load portions are similar to the gen-set capacity or even bigger. The goal of the absolute reserve mode is that the system provides always the same reserve power capacity independent of how many gen-sets are currently running and this why this mode perfectly fits for industrial plants with large loads.
6.11.2
Basics
The setpoint Pwr Management enables and disables the gen-set to be active within the power management of the group and make automatic load demand start and stop. If the power management is disabled, the gen-set will run or not depending only on the binary input Sys Start/Stop and the start and stop will not depend on the load of the group. The binary input Sys Start/Stop activates and deactivates the gen-set. If the input is not active, the gen-set will stop with delay #SysAMFstopDel after the input has been deactivated and will not start again. It can be started in MAN mode only. When the input is activated again, the delay #SysAMFstrtDel will start to count down and after that the gen-set is activated and can start due to power management.
NOTE: The gen-set will take part of the power management (= will be active) only if the controller is in AUT mode! NOTE: The gen-set performs load and VAR sharing whenever it is connected to the busbar i.e. it is independent on whether the controller is in AUT or MAN mode or whether the power management is active or not.

∑
Running NomPwr = the sum of the nominal power of all active gen-sets within the group, that are connected to the bus.
If the current system reserve drops below the adjusted reserve for start, the delay #NextStrt Del will start to count down on the gen-sets, which have decided to start. If the reserve remains under the limit for the entire countdown period, the gen-set(s) will start. If the system reserve drops below zero (i.e. the system is overloaded), the delay #OverldNext Del will start to count down on the gen-sets, which have decided to start. If the reserve remains under the limit for the whole countdown period, the gen-set(s) will start. If the system reserve goes above over the adjusted reserve for stop, the delay #NextStopDel will start to count down on the gen-sets, which have decided to stop. If the reserve still remains over the limit, the gen-sets will stop. There are two pairs of setpoints for adjusting reserves for start and stop. Normally the pair #LoadResStrt 1 and #LoadResStop 1 is active. By the binary input Load Reserve 2 the second pair #LoadResStrt 2 and #LoadResStop 2 is activated. With adjusting nonzero value to the setpoint #Min Run Power and activating the function by binary input Min Run Power, it is possible to limit the number of running gen-sets so that the total nominal power of the loaded gen-sets will never drop below this level even if the reserve for stop is fulfilled.
NOTE: If the setpoint is adjusted to maximum, the function will force all gen-sets to run.
6.11.4
Priorities
The priority of the gen-set within the group is determined by the setpoint Priority. A lower number represents “higher” priority, i.e. a gen-set with a lower number will start before another one with higher number. If the binary input Top Priority is active, the gen-set gets highest priority (0) independent of the setpoint setting. If more than one gen-set have the same priority, they will act as “one big” gen-set.
NOTE: It is possible to switch automatically priorities of the gen-sets by using the Run Hours Equalization function which can be set up in the #RunHrsMaxDiff setpoint.
6.11.5
Start and stop
The controller will decide to start the gen-set at the moment when the reserve has dropped below the reserve for start and the gen-sets with higher priorities (lower priority numbers), that are available for power management, do not have enough capacity to get the reserve back over the start level or cannot fulfil the adjusted minimal running power NT

The controller will decide to stop the gen-set at the moment when the reserve has increased over the reserve for stop and the gen-sets with higher priorities (lower priority numbers), that are available for power management, have enough capacity to keep the reserve over the start level and also can fulfil the adjusted minimal running power
NOTE: When evaluating the stop condition, the controller computes actual reserve without taking in account its own nominal power, i.e. it evaluates how the reserve will be if the respective gen-set stops. Load [kW] Pnom Gen-set 3 Priority 3

6.11.6
If a Shutdown or BOC alarm occurs, the gen-set will be taken out from the power management and the next gen-set will start if necessary. If a Slow stop alarm occurs, the gen-set will be taken out from the power management, but the alarm will be suppressed for a definite period of time to give the next gen-set chance to start and connect to the bus to get the reserve back over the start level. The alarm is suppressed until the reserve gets back over the start level (this can occur either because the next gen-set has connected to the bus or the load has decreased) or the timeout given by the setpoint #SlowStopDel has elapsed. The alarm will not be suppressed if there is no other available gen-set that can start.

6.19.3
Regulation control loops overview
6.19.3.1
Speed/frequency control loop
The speed/frequency control loop is active during the synchronization, when the gen-set frequency is controlled to the same value as the mains or bus have, i.e. to achieve zero slip frequency.
6.19.3.2
Differential angle control loop
The differential angle control loop is active during the synchronization, when the “near to zero” slip frequency has been successfully achieved and then the differential angle between generator and mains/bus voltage shall be reduced to zero.
6.19.3.3
Power control loop
The power control loop is active during the parallel to mains operation. The recognition of parallel to mains operation is done on the basis of the binary input MCB feedback. In MINT the setpoint #SysLdCtrl PtM must be also set to BASELOAD.
6.19.3.4
Load sharing control loop
The load sharing control loop is active in MINT, whenever the GCB is closed and the binary input MCB feedback is not active or the setpoint #SysLdCtrl PtM is in LDSHARING position.
6.19.3.5
Voltage control loop
The voltage control loop is active during synchronization (the generator voltage is controlled to the same value as the mains or bus have) and during island operation in SPtM (the gen-set voltage is controlled to the nominal voltage). During multiple island operation in MINT, the voltage control loop is also running “in the background” of the VAr sharing loop (using P, I parameters multiplied by 0.1) to maintain the voltage at the nominal level. NOTE: Since IC-NT SW v. 1.4.1 only the first controller (with the lowest address at the CAN has) active voltage control loop. Other controllers are adapting voltage according to bus to the first one. All controllers have active VAr Share regulation loop.
6.19.3.6
Power factor control loop
The power factor control loop is active during the parallel to mains operation. The recognition of parallel to mains operation is done on the basis of the binary input MCB feedback.
6.19.3.7
VAr sharing control loop
The VAr sharing control loop is active during multiple island operation in MINT application.
6.19.4
PI regulation adjustment
The exact adjustment of a PI loop always depends on the engine and generator characteristics. However, a general rule can be followed in the beginning of the adjustment process:
Prepare the system for adjustment, i.e. set the limits for related alarms temporarily to values which will disable the alarms, set the synchro timeout to the maximum value, etc. Adjust the gain to 5% and integration to 0%. Switch the gen-set to MAN mode, start it and put it into the operation phase, where the appropriate regulation loop is active. Increase the gain slightly until the controlled quantity starts to oscillate. Then put it back to approx. one half of the value where the oscillations started.
NT
InteliCompact , SW version 1.4 InteliCompact-NT-1.4-Reference Guide-r3.pdf, ©ComAp – March 2013
115
Increase the integrative factor slightly to achieve acceptable response to changes. Too small an I-factor will cause an excessively slow response, while too high an I-factor will cause overshooting or even oscillations.
NOTE: It may be helpful to disable issuing the GCB close command when adjusting synchronization loops. Adjust the setpoint Phase Window to 0 to disable it. Adjust the setpoint back to its original value after the adjustment is finished. CAUTION! Be ready to press the emergency stop button in the event that the regulation loop starts to behave unacceptably.

7 Setpoints Setpoints are analog, binary or special data objects which are used for adjusting the controller to the specific environment. Setpoints are organized into groups according to their meaning. Setpoints can be adjusted from the controller front panel, PC, MODBUS, etc.
7.1
Password protection
Each setpoint can be protected by a password against unauthorized changes. Password protection can be assigned to the setpoints during the configuration procedure. See the chapter Operator guide for instructions on how to enter and modify a password. See also the LiteEdit help to learn about working with a password in LiteEdit.
7.2
Setpoint synchronization
Setpoints marked with a “#” sign at the beginning of their names are synchronized with other controllers present on the CAN bus line, i.e. the system will ensure that the respective setpoint will have an identical value in each connected controller. If the setpoint is changed in one controller, the same change will occur in all other controllers. This function is necessary especially for MINT application, where the system of Power management is based on fact that the respective setpoints are identical in all controllers. All parameters marked as shared (“#”) are overwritten during archive download in case there is no another single controller visible on the CAN bus. In case there is another controller on the CAN bus, the shared parameters are not overwritten.

CAUTION! Do not write setpoints repeatedly (e.g. power control from a PLC by repeated writing of baseload setpoint via Modbus) The setpoints are stored in EEPROM memory, which can be overwritten up to 5 10 times without risk of damage or data loss, but it may become damaged, when the allowed number of writing cycles is exceeded!

11.2.2
Modem setup procedure
Analog modems obviously do not require any setup. The only case in which setup could be necessary is if the modem has been bought in a country with a telephony system different than the target country where the modem will be used. GSM modems need to be set up prior to using them with the controller. Use the gm_setup program (installed together with LiteEdit) to perform initial setup of the modem. See the latest Inteli Communication Guide (available on the ComAp web site) for details. The setup must be done while a SIM card is inserted. NOTE: It is always recommended to use modems bought in and approved for the target country.
11.3 Internet connection A PC can be connected to the controller also remotely via Ethernet (internet, intranet). An appropriate Ethernet communication module must be used.
11.3.1

11.3.3
Using a web browser
The IB-Lite module with firmware version 1.1 and above makes it possible to use any web browser for basic monitoring and adjustment of the controller. Direct your web browser to the IP address of the module, e.g. http://192.168.1.254 and then enter the access code.
11.3.4
IB-Lite setup procedure
NOTE: Setting the module up requires a certain familiarity with network administration. Ask your IT specialist for assistance. The default settings of the module are IP = 192.168.1.254, Netmask = 255.255.255.0 and Gateway = 192.168.1.1. The default password for service webpages is “comap” (or “0”). To restore the default settings, close the “restore default setting” jumper located on the module before switching the controller on and remove it few seconds after the controller has been switched on. NOTE: The default settings can be changed directly from the controller panel by pressing the “Page” button and using ▼, ▲ and “Enter” to get to the “Comms Settings” menu (THIS APPLIES TO FIRMWARE VERSIONS 1.3 AND HIGHER).
11.3.4.1
Configuration
1. Plug the module into the controller and power the controller on. 2. Connect the module into your Ethernet network. If the default address does not match local network parameters (i.e. the network segment does not use the IP range 192.168.1.xxx or the IP 192.168.1.254 is occupied), connect the module directly to your PC using a cross-wired cable. See details in the Installation chapter. 3. If you are connected directly, you have to change temporarily the IP address and subnet mask of your PC Ethernet connection. Use the following settings: DHCP disabled, IP from the range 192.168.1.1 – 192.168.1.253 and subnet mask 255.255.255.0. After the IB-Lite setup is finished, restore your PC setting back to the original values. 4. Start a web browser and direct it to http://192.168.1.254/sp_config.htm. 5. After a successful login the configuration page will be displayed. 6. It is recommended to change the user name and password and keep the new values confidential. 7. Consult your IT specialist for proper IP settings. 8. Consult your e-mail provider for proper e-mail settings. Note that also most public SMTP servers require authentication and e-mails must be sent from an existing address. 9. If you want to enable access only for clients with a specified IP address, tick the checkbox “Trusted clients” and fill-in the allowed IP addresses. NOTE: See also the latest LiteEdit Reference Guide (available on the ComAp web site) for more information about IB-Lite setup.
11.3.4.2 1. 2. 3. 4. 5.
Firmware upgrade
Follow steps 1–3 of the configuration procedure above. Start a web browser and direct it to http://192.168.1.254/sp_fw_upld.htm. After a successful login the configuration page will be displayed. Press the button “Browse” and select the appropriate firmware file. Press “Upload new firmware” button. After the firmware upload is finished, the module will restart.
NOTE: Interrupting the upload will NOT cause any damage. Just repeat the upload again. NT

System integration
The controller can be integrated into a building management or similar system using an RS232, RS485 or Ethernet interface and MODBUS protocol. The following modules can be used for this purpose: 1. IL-NT RS232 2. IL-NT RS232-485 3. IB-Lite (Modbus/TCP) The setpoint COM1 Mode (RS232) resp. COM2 Mode (RS485, Ethernet) must be set to the MODBUS position. The speed of MODBUS communication for RS232 and RS485 can be adjusted by the setpoint ModbusCommSpeed. In the case of IB-Lite adjust this setpoint to 57600 bps. See a more detailed description of the MODBUS protocol in a separate chapter.
11.3.8
AirGate
technology for easy plug-and-play wireless communication is incorporated into the product. An ordinary SIM card with GPRS service is suitable for this system. This overcomes problems with the necessity for a special SIM card (fixed and public IP), firewalls and difficult communication settings. http://www.comap.cz/news-room/news-and-events/detail/AirGate http://www.comap.cz/news-room/news-and-events/detail/The-Rainbow-rises-for-remotemonitoringapplications/

11.4 Modbus protocol The Modbus protocol can be activated on the RS232 or RS485 port. The physical link parameters are:
8 data bits 1 stop bit no parity communication speed selectable by the setpoint ModbusComSpeed
The Modbus/TCP protocol uses the TCP/IP frames as the transport layer for Modbus frames. This protocol is available via the IB-Lite module on port 502. The following features from the Modbus specification are supported:
Transfer mode RTU Function 3 (Read Multiple Registers) Function 6 (Write Single Register) Function 16 (Write Multiple Registers)
The response to an incoming message depends on the communication speed. The delay is not shorter than the time needed to send/receive 3,5 characters. See the latest Inteli Communication Guide (available on the ComAp web site) for details and examples. The complete description of the Modbus communication protocol can be found in the Modbus Protocol Reference Guide PI-MBUS-300 and Open Modbus Specification Release 1.0. Both documents are available on the web. NOTE: The complete list of available registers can be obtained from LiteEdit. Open an online connection to the controller or open offline an archive and go to the menu Controller -> Generate Cfg image to get the register list.

SYMPTOM Governor output does not work; the output level is continuously at the lower or upper limit. CAUSE
SOLUTION
Wrong (opposite) position of the setpoint Speed Check the setpoint position if it fits the Governor Gov Char. requirements. Opposite or wrong wiring of the Governor/AVRi Check and correct the wiring. output. The governor output is switched to PWM mode Put the PWM jumper at the governor output into but the governor needs voltage mode or vice the proper position according to the Governor versa. requirements.
SYMPTOM The cranking is cut off too early, the engine does not start. CAUSE
SOLUTION
The setpoint Starting Oil P is adjusted too low.
Adjust the setpoint to a higher pressure level than can be achieved by cranking only. Note, that under cold condition the oil pressure achieved during cranking can be higher.
W terminal is connected to the pickup input of the controller, but autodetection of frequency-tospeed ratio was not performed (e.g. if the controller was previously used with another engine with another charging alternator).
Disconnect the W terminal from the pickup input, then start the gen-set in manual mode and wait until the gen-set is ready to take the load. Then stop the engine and connect the W terminal back. The autodetection process will be performed during next start.
SYMPTOM The MCB control does not work properly, the alarm MCB fail is present all the time. CAUSE
SOLUTION
The position of the setpoint MCB Logic does not Switch the setpoint MCB Logic into proper match the current MCB wiring. position.
SYMPTOM The communication via CAN bus with other engines, extension units or ECU does not work, i.e. you do not see other engines in the CAN16 or CAN32 value or the controller shows an alarm in the Alarmlist that some of extension units or ECU does not communicate. CAUSE
SOLUTION
The wiring of the CAN bus network is not provided as linear bus without nodes.
Correct the wiring as described in the chapter CAN bus wiring.
