Troubleshooting
5-28 Manual # 42-02-2P24
MPI A or B RGOK DROPPED
Description:
No voltage detected at terminal RG5 on the TC-MPI board. The OK indication from the rope
gripper, which was previously present, has dropped while the car was in motion.
Troubleshooting:
1. Check emergency brake microswitch wiring.
2. Cars without a rope brake should have a permanent jumper between RG5 and RG7.
3. Make sure there is 120V at EBPS terminal of the TC-MPI board.
4. One of the EBP1, EBP2, EBP3, or EBP4 relays may have failed open.
5. Check that when EBPS is high and 2MV is high that there is 120V at terminal RG1.
6. Reset the rope brake: Car on Inspection. Press fault reset on the HC-CTL board. Hold down the EB
RESET button on the TC-MPI board for at least 8 seconds.
MPI A or B RGOK FAILED TO ACTIVATE
Description:
No voltage detected at terminal RG5 on the TC-MPI board.
Troubleshooting:
1. Check emergency brake microswitch wiring.
2. Cars without a rope brake should have a permanent jumper between RG5 and RG7.
3. Make sure there is 120V at EBPS terminal of the TC-MPI board.
4. One of the EBP1, EBP2, EBP3, or EBP4 relays may have failed open.
5. Check that when EBPS is high and 2MV is high that there is 120V at terminal RG1.
6. Reset the rope brake: Car on Inspection. Press fault reset on the HC-CTL board. Hold down the EB
RESET button on the TC-MPI board for at least 8 seconds.
MPI A or B RGOK FAILED TO DEACTIVATE
Description:
The processor is reporting that the RGOK monitor signal is active with the Emergency Brake
disabled.
Troubleshooting
:
1. Check that no wire is inserted into the RG5 terminal on the TC-MPI board. When the Emergency Brake
option is set to DISABLED, the controller expects no voltage at the RG5 terminal.
MPI A or B SPC IS OFFLINE
Description:
TC-MPI board safety processor MP is offline.
Troubleshooting:
1. Power to the TC-MPI board may not be connected. Check the CAN bus connection between the TC-MPI
board and the CAN hub.
2. Make sure jumper JP6 on the TC-MPI board is not shorted.
3. If the MP indicator is not lighted, reboot the processor by cycling power to the controller or by remov-
ing the CAN bus connection to the TC-MPI board for a few seconds.
MPI A or B UET SW OVERSPEED
Description:
The processor has detected an Up Emergency Terminal overspeed. Power will be removed
from brake and motor to bring the car to an immediate halt.
Troubleshooting:
1. Check the integrity of the landing/positioning system encoded tape.
2. If the job has a physical UET switch, check the switch and connections.
If this is occurring on a job that is just being set up or adjusted or has had this problem sporadically:
3. Check F7 menu U/DET Option setting (parameter 65).
4. Check F7 menu UET Speed, Distance, and Delta Speed settings.
5. Check F7 menu settings for the terminal slowdown switch immediately preceding the UET switch.
