Possible Cause / Suggested Ac-
tion
Expected feedback from a contac-
tor is missing after checkback time
was over.
Check wiring of auxiliary contact to
the correct UMC input.
Check contactor
Increase checkback time
No motor current after motor was
switched on and checkback time
was over. Or motor current falls
below 20% while motor is running.
Check supply side
Check that I was set correctly
e
Check current factor if set
Increase checkback time
Check between UMC and motor
Check wiring between UMC and
motor
The IO module does not respond
during start-up of UMC.
Check wiring between UMC and module
Check supply of module
Check status LEDs of the module
The VI15x module does not re-
spond during start-up of the UMC.
Check wiring between UMC and module
Check supply of module
Check status LEDs of the module
Check wiring, short circuit at ana-
logue output
