MPI A or B EBPS MONITOR FAULT
Description:
The EBPS, Emergency Brake Power Supply, (A and or B) input to the TC-MPI is in an opposite
state from the RGR1_A/B, RGR2_A/B, and RGOK_A/B inputs.
Troubleshooting:
1.
Check for 120 VAC on TC-MPI board terminal EBPS. If not present, check governor overspeed switch or
fuse FEB (3 A type MDQ or 313 slow acting fuse).
2. Check terminals RG1 and RG7 for 120VAC (power supply output).
3. If no power at RG1 and RG7, check power supply
MPI A or B EEPROM FAULT
Description:
A device error has been detected during a cyclic redundancy check (code=1) or while read-
ing from or writing to the device (code=2).
Troubleshooting:
1. Reset the microprocessor.
2. Check that serial data links are properly connected and routed using shielded cable (through conduit
where appropriate).
3. Check for recently installed equipment that might be generating electrical noise.
4. If the error occurred while updating firmware, re-attempt the update procedure.
MPI A or B EMERGENCY BRAKE CYCLE TEST FAULT
Description:
One of the EBP1/2/3/4 relays has failed the cycle test. If moving, the elevator will be taken
out of service at the next landing. If in a landing zone, the elevator doors will open and the elevator will be
taken out of service.
Troubleshooting:
MPI A or B ETS SHUTDOWN FAULT
Description:
The named processor has detected that there is a difference in emergency terminal switch
data (position or open/closed status) between itself and the other processor. If moving, the car will be
stopped at the next landing, the doors opened for passenger exit, and the car taken out of service. If in a
door zone, the car will remain at the landing, open doors for passenger exit, and be taken out of service.
Troubleshooting:
1. Check that emergency terminal switch F7 menu designations (virtual, physical, unused) and positions
are correct.
2. If switches are physical, check their actual positions and proper operation.
3. Test elevator for proper operation.
MPI A or B EXCESSIVE FAULTS SHUTDOWN
Description:
The named processor has detected faults beyond an established limit in a circumscribed
period of time.
Troubleshooting:
1. Check the connections to and from the TC-MPI board.
2. Reset the microprocessor.
3. Test elevator for proper operation.
MPI A or B GOVERNOR OVERSPEED
Description:
The named processor has detected the opening of the governor overspeed switch. The car
will be brought to an immediate emergency stop.
Troubleshooting:
1. If the governor overspeed switch has not opened, check switch integrity and connections.
2. If the car had in fact exceeded governor overspeed switch opening speed, troubleshoot to determine
that cause of the overspeed.
