Troubleshooting
ALARM 92, No flow
A no-flow condition has been detected in the system.
parameter 22-23 No-Flow Function is set for alarm.
Troubleshoot the system and reset the frequency converter
after the fault has been cleared.
ALARM 93, Dry pump
A no-flow condition in the system with the frequency
converter operating at high speed may indicate a dry
pump. parameter 22-26 Dry Pump Function is set for alarm.
Troubleshoot the system and reset the frequency converter
after the fault has been cleared.
ALARM 94, End of curve
Feedback is lower than the set point. This may indicate
leakage in the system. parameter 22-50 End of Curve
Function is set for alarm. Troubleshoot the system and
reset the frequency converter after the fault has been
cleared.
7 7
ALARM 95, Broken belt
Torque is below the torque level set for no load, indicating
a broken belt. 22-60 Broken Belt Function is set for alarm.
Troubleshoot the system and reset the frequency converter
after the fault has been cleared.
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.

This alarm is only for F Frame 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 frequency
converter.
2 = right inverter module in F1 or F3 frequency
converter.
3 = right inverter module in F2 or F4 frequency
converter.
5 = rectifier module.
ALARM 244, Heatsink temperature
This alarm is only for F Frame frequency converters. It is
equivalent to Alarm 29. The report value in the alarm log
indicates which power module generated the alarm:
