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)

C. BASIC CALLBACKS SOLUTION 1. HOW TO CHECK THE SAFETY CHAIN FROM LANDING 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 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 b been een 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:
