DESCRIPTION

Hardware Configuration The REF542plus is composed of two pieces: the HMI (Human Machine Interface) for local control and visualization and the CU (Central Unit) containing all the electronic boards. The two pieces are connected by means of a serial cable. The hardware configuration is organized as follows, with a basic set of boards always present and some optional ones. The basic configuration always includes:

Main board The main board is the heart of the unit. A Digital Signal Processor carries out the measurement and protection functions, while a Micro Controller carries out the control functions. Power supply Four different kinds of power supply are available, to cover all the applications from 48Vdc up to 220Vdc: – 110VDC fixed

The HMI, Human machine interface, for local control and visualization

– 220VDC fixed

The Central Unit, with: 1 mainboard 1 power supply 1 Binary Input and Output board 1 Analog input board.

– Full range between 90VDC and 220VDC.

The basic configuration always also includes: – the connector kit to allow wiring of the REF542plus inside the panel – the cable to connect the HMI and Central Unit – the software program to parameterize the protection functions – the detailed technical description (I/O list, meaning of alarms and warning LEDs, connection diagram).

– Full range between 48VDC and 85VDC For all of the above, the tolerance is –15%, +10%. Binary Input and Output board The binary input and output board is used to interface the primary process e.g. to read the status information of the circuit-breaker through the auxiliary contacts, to send the commands to operate the circuit-breaker. The inputs of the binary signals are isolated by optic-couplers, while binary outputs are implemented with mechanical relays. The binary input and output board has: – 14 binary inputs – 7 binary outputs – 1 watchdog binary output to signal internal failures – 1 coil supervision circuit. The Binary Input and Output board is available in two types. With the minus (– ) of 12 out of the 14 binary inputs connected together or with completely separate inputs. The binary Input and Output board is available in 2 types. The binary inputs can have both terminals (-) and (+) completely separated one from the others. To make wiring easier, the minus (-) of 12 out of 14 binary inputs can be connected together on the board it self by a copper line. The connection diagram shows these connections.

1 Analog Input board Two types of analog input board are available. For conventional instrument transformer: – 3 input channels for current transformers (/1A or / 5A) for line current sensing – 3 input channels for voltage transformers (/100V or /110V) for phase voltage sensing – 1 input for the toroidal transformer for earth fault current sensing (/1A). For non-conventional sensors: – 3 input channels for current sensors (Rogowsky coil) for line current sensing – 3 input channels for voltage sensors (Voltage divider) for phase voltage sensing – 1 input for the toroidal transformer for earth fault current sensing (/1A). Sensors have some unique qualities directly affecting both the manufacture and the use of the switchgear. Some of these features are particularly important for the manufacturer as they bring about shorter delivery times and smart many-sided integration. On set only covers all applications. For example: – Linear, no saturation – Wide rated range – No accuracy versus burden calculation – Standardized components – More time for equipment specification – Shorter lead-time for switchgear – Combined current and voltage sensor together in the same unit – Coupling electrode for voltage indication. Please refer to the sensor technical catalogue for Medium Voltage Switchgear Kit for more information on sensors.

Options Optionally, the REF542plus can be equipped with: the supplementary Binary Input and Output board: with this board, REF542plus makes 28 inputs and 14 outputs available. This board is used when there are several signals to acquire or when some signals need to be replicated as outputs. It can also be provided and left inside the REF542plus for future expansions. The Analog output board: the optional analog output module has four configurable outputs which can be set in the range from 0 to 20 mA or 4 to 20 mA. Each of the four channels can be independently activated and parameterized to transmit the following analog output quantities: – All voltage quantities directly from the analog inputs – All current quantities directly from the analog inputs – Calculated residual current – Calculated residual voltage – Calculated apparent, active and reactive power – Calculated power factor The measurements to be transmitted are easily selected with the configuration software. Modbus RTU communication board: the communication board implements the modbus RTU standard protocol. The physical communication interface is according to the galvanically insulated RS 845 standard. Two distinct channels are available. This board allows easy integration of the REF542plus in a substation automation system. With this board, all the measurements, circuitbreaker status and fault recorder data, can be transferred to the automation system. It is also possible to send commands to open and close the circuit-breaker and to parameterize the protection functions. When ordered, the communication board is delivered with the complete memory map. Note: the analog output board and the modbus RTU communication board cannot be present simultaneously in the same REF542plus.

1 - Electronic keys Two different electronic keys are provided. One key is to parameterize the protection functions. The other one is for control modes selection: local or remote. The key sensor recognizes which electronic key is in use. 2 - Display The REF542 Plus display is divided into two parts. The left half graphically shows the single line diagram with the current status of the circuitbreaker and of the earthing switch. The right half of the LCD display is for plain text representations, such as measurement values, main menu and submenus descriptions, protection signals events and alarm texts. 3 - Indication LEDs The operational status is called ‘Ready’ and is displayed by a green LED. The unit is not operational when this LED is off. When the optional modbus communication board is present, the communication status is represented by the LED Network Communication. The LED colour is usually green and changes to red if a communication failure occurs. The interlocking error LED turns temporarily to red in the case of a switching action which violates the interlock conditions. 8

5 - Alarm LEDs These are bicolour LEDs, so they can be in four different states, switched off, green, red and amber. The protection functions are divided into three groups, depending upon their applications: Current protections; Earth fault protections; Voltage protections.

Each protection group has its own dedicated LED. In normal conditions, the LED is green. When a protection starts timing, the LED turns amber. Should a protection generate a trip, the LED becomes red. The protection that tripped can be identified by looking at the events list on the REF542 Plus display. Other alarm LEDs are dedicated to specific conditions such as: – SF6 lockout, the dedicated led is red when the SF6 pressure is at the lockout level, preventing any further operation of the circuit-breaker (this alarm is not used when the circuit-breaker is of the vacuum type); – trip circuit failure: the dedicated LED turns to red when the REF542 Plus detects a failure in the circuit-breaker trip circuit (this alarm is not used when the contactor is used instead of the circuitbreaker); – spring discharged: if the circuit-breaker spring is not charged within the predefined interval, an alarm is generated (this alarm is not used when the contactor is used instead of the circuitbreaker).
