Troubleshooting
ALARM 96, Start delayed
Motor start has been delayed due to short-cycle
protection. 22-76 Interval between Starts is enabled.
Troubleshoot the system and reset the frequency converter
after the fault has been cleared.
WARNING 97, Stop delayed
Stopping the motor has been delayed due to short cycle
protection. 22-76 Interval between Starts is enabled.
Troubleshoot the system and reset the frequency converter
after the fault has been cleared.
WARNING 98, Clock fault
Time is not set or the RTC clock has failed. Reset the clock
in 0-70 Date and Time.
WARNING 200, Fire mode
This indicates the frequency converter is operating in fire
mode. The warning clears when fire mode is removed. See
the fire mode data in the alarm log.
WARNING 201, Fire mode was active
This indicates the frequency converter had entered fire
mode. Cycle power to the unit to remove the warning. See
the fire mode data in the alarm log.
WARNING 202, Fire mode limits exceeded
While operating in fire mode one or more alarm conditions
have been ignored which would normally trip the unit.
Operating in this condition voids unit warranty. Cycle
power to the unit to remove the warning. See the fire
mode data in the alarm log.
Warning 219, Compressor Interlock:
At least one compressor is inversely interlocked via a
digital input. The interlocked compressors can be viewed
in par. 25-87.
ALARM 243, Brake IGBT
This alarm is only for F Frame/12-pulse frequency
converters. It is equivalent to Alarm 27. The report value in
the alarm log indicates which power module generated
the alarm:
1 = left most inverter module.
2 = middle inverter module in F2 or F4/F12 or
F13 frequency converter.
2 = right inverter module in F1 or F3/F10 or F11
frequency converter.
3 = right inverter module in F2 or F4/F12 or F13
frequency converter.
5 = rectifier module.
This alarm is only for F Frame/12-pulse frequency
converters. It is equivalent to Alarm 29. The report value in
the alarm log indicates which power module generated
the alarm:
1 = left most inverter module.
2 = middle inverter module in F2 or F4/F12 or
F13 frequency converter.
