SCHINDLER SCH-3300 Release 4

BASIC MAINTENANCE TASKS The purpose of this manual is to provide to the service mechanics the procedures for perform the main operations to be done during the regular maintenance visits, including code tests, in Non OTIS units. Only the relevant operations (those which must be done following a special procedure) are described. If during the maintenance operations in this model you find any task that can’t be done following the OTIS procedures and is not described here, please contact with EMEA Non OTIS Support Center ([email protected]).

All jobsite work activity must be in full compliance with Otis World Wide Jobsite Safety Standards (WWJSSS). When carrying out this procedure particular consideration should be given to control of the elevator, LOTO, hoisting and rigging, ensuring public safety (signs and barriers), working in close proximity of unguarded rotating equipment (sheaves) and the wearing of appropriate PPE (hand gloves, etc.). It is required that the mechanic(s) carrying out the repair complete the appropriate JHA for the task at hand to familiarize themselves with the work environment. If you are unsure of the WWJSSS standards in regard to the work task at hand, immediately stop work and refer to your Supervisor.

OTIS Elevator Cardinal Rules ALWAYS

use fall protection when a fall hazard exists.

ALWAYS

lock and tag out equipment when power is not required.

ALWAYS

control live electricity and rotating equipment when working within close proximity of the hazard.

ALWAYS

establish and maintain control of the elevator prior to accessing/egressing the hoistway, working on the car top, and in the pit.

ALWAYS

follow proper jumper procedures.

ALWAYS

use certified and inspected hoisting and rigging equipment.

NEVER

ride the car top with the elevator in normal operation.

NEVER

work above or below others when working in the hoistway.

No team members are to use the tools, materials, or methods described in this document without reading, following, and understanding the document prior to the commencement of the work or task.

3. TEST OF MANUAL RESCUE OPERATION The manual rescue procedure is described in a sticker on the cover of the maintenance panel. Please, follow these instructions in case of doubt. The rescue operation is performed by an electric device called PEBO (Pulse Electromagnetic Brake Operation) which opens and closes the brake in short intervals. The button and switch used for this operation are located on SEM board in maintenance panel. For safety reasons, in case of overspeed contact in governor is engaged, rescue operation is not possible. 1. Make a call for sending the car to the top landing. Leave the car to open and close the doors in order to be sure there are no passengers in car. 2. Put the lift in ERO mode and move the car downwards to an out of landing position (blue led LUET is off). 3. Disconnect the main switch (JH)

7. Release the DEM button and put the JEM switch in OFF position. The lift will perform a correction run. 4. TEST OF AUTOMATIC RESCUE OPERATION Automatic rescue operation is included as standard in Schindler 3300 product. When a power failure happens, the car must be moved at reduced speed to the nearest landing in the favorable sense of unbalance. 1. Make a call for sending the car to the top landing. Leave the car to open and close the doors in order to be sure there are no passengers in car. 2. Put the lift in ERO mode and move the car downwards to an out of landing position (blue led LUET is off). 3. Switch the power off by disconnecting the main switch (JH). 4. Place a shunt between the pins 6 and 7 on LDU connector of SEM board. Put the lift in NORMAL mode.

5. After approx. 30 seconds, the car should fully close the doors and move upwards at a very reduced speed (depending on the distance, it could take minutes to reach the nearest landing). When the nearest landing is reached (led LUET is ON), doors fully open and lift stays out of service with doors opened. 6. Remove the shunt and switch the power on by connecting the main switch (JH). The lift will close the doors and will perform a correction run. 5. TEST OF EMERGENCY CAR LIGHT AND ALARM In SCH-3300, the emergency car light is the alarm button illumination. 1. Make a call for sending the car to the top landing. Leave the car to open the doors and then turn off the car light by disconnecting SIL switch. Check alarm button is illuminated. 2. Press the alarm push button and check communication with call center is established. 3. Reconnect SIL and check the car light turns on again. 6.

6. Open the landing door and check visually the position of the car. Close the door and try to move the car in ERO mode in down direction. Check that even when the screen shows a speed different to cero the car doesn’t move (it could be necessary to put the lift in open loop: in menu 10, set option 102 to 1). 7. Switch to Normal. Check that safety chain is opened (at least one of the asterisks is off). 8. Disengage the car by switching to ERO and moving the car in up direction. 9. Reset the safety contacts: KF switch (safety gear in car) is located at the bottom of the car so move the car down in ERO mode to a position where switch can be reached from the pit. Check also in the pit that the switch of the governor tension device is in normal position. Resetting KBV switch (governor overspeed contact) will require shunting temporarily the contact (shunt in SMIC board, KBV.1-KBV.2) for getting access to the governor in Inspection mode. 10. Remove the shunt and put back the lift in normal operation. After a correction run, car should be in idle ready for attending calls. Warning: If safety gear test or safety switches performance is not compliance, investigate root cause and correct the issue before turning the car over to the customer.

C. BASIC CALLBACKS SOLUTION 1. HOW TO CHECK THE SAFETY CHAIN FROM LANDING PANEL Safety chain contacts in the landing panel are connected to SMIC board. All the safety chain contacts in car (including car door lock contact) are connected in series so they cannot be checked independently from the landing panel. The safety chain voltage is 24V with safety chain closed and 60V when it is opened. The reference point is 0Vdc (i.e LDU.5). The possible verifications are as follows: 1. KSS.1  Beginning of safety chain. IUSK checking point. 2. KSS.2 = SKS.1  Slack belt contact. 3. SKS.2  Pit safeties (Stop, ladder, governor tensioner). ISPT checking point. 4. SKS.3  Hoistway doors locks. RTS checking point. 5. SKC.1  Beginning of safety chain in car (including car door lock). 6. SKC.4 = KBV.1 End of safety chain in car (including car door lock). 7. KBV.2 = ESE.2  Governor overspeed contact (car and counterweight, if exists). 8. ESE.3 = SEM.5  Stop and ERO switches (bridged to ESE.2 if XESE plug is connected). 9. SEM.6  Emergency rescue contacts. End of safety chain. ISK checking point.

There is a sticker on the cover of the landing panel showing the main contacts of the safety chain

2. HOW TO RESET FATAL ERROR There are some faults that, even when the cause of the error has been cleared, leave the lift out of service. Some of them require a reset to be performed on SCPU board. Some others require a Fatal Error Clearing Process through the embedded service tool:

3. HOW TO RESET THE LIFT FROM TOP OF THE CAR In order to prevent the mechanic to get trapped on top of the car when a failure happens while travelling on inspection mode, a procedure for reset the lift from top of the car has been implemented in software versions later than 9.56. The procedure is as follows: with lift in Inspection mode, press STOP on inspection box and then press both Up and Down buttons at the same time and hold for a few seconds. Reset of SCPU board is performed. 4. HOW TO CHECK THE LIFT STATUS On the lcd display, while being in the main screen, two digits at the bottom right corner show the status of the lift. The meaning of these digits is according with the following table:
