MPI-A SPB IS OFFLINE
Description:
TC-MPI board safety processor SPB 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 JP1 on the TC-MPI board is not shorted.
3. If the SPB indicator is not lighted, reboot the processor by cycling the power to the controller or by
removing the CAN bus connection to the TC-MPI board for a few seconds.
MPI-A or B 2L BUS IS LOW
Description:
The 2L AC bus has fallen below the expected voltage.
Troubleshooting:
1. Check the 2L bus fuse.
2. Check connection at PMT terminal X4.
MPI-A or B 2MV BUS MONITOR FAULT
Description:
The 2MV AC bus monitoring input on the CTL board is no longer detecting correct voltage.
Troubleshooting:
1. Check the 2MV bus fuse.
2. Check connection at PMT terminal X4.
MPI-A or B ACTUAL AND REQUESTED DIRECTION MISMATCH
Description:
The processor has detected that the commanded run direction does not match the data
reported by the positioning system. Power will be removed from brake and motor to bring the car to an
immediate halt.
Troubleshooting:
1. Check CAN bus connections from landing positioning sensor to cartop box MC-LSI board.
2. Check CAN bus connections from MC-LSI board to TC-MPI board in controller.
3. Check 24V power to MC-LSI board in cartop box.
4. Check condition and proper installation of encoded tape for positioning system.
5. Check position sensor for excessive dirt or clogging.
MPI-A or B CONTRACT OVERSPEED
Description:
The processor has detected a contract overspeed (F7 menu, parameter 145). Power will be
removed from brake and motor to bring the car to an immediate halt. If changes have been made to LF.22,
you must reset all three microprocessors on the TC-MPI board.
Troubleshooting:
1. Check the integrity of the landing/positioning system encoded tape.
2. Use a hand tach to check the speed at which the overspeed is triggered.
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 Contract Speed setting (parameter 149).
4. Check F7 menu Contract Overspeed setting (parameter 145 should be set to about 108% of Contract
Speed).
5. Check F7 menu Hoist Motor Speed setting (parameter 148). Check correct gear ratio, KEB drive param-
eter LF.22.
6. Check drive Contract Speed, High Speed, Sheave Diameter, Gear and Roping Ratio, Integral Gain, and
Encoder settings.
