End Of Curve; Broken Belt; Start Delayed - Danfoss VLT HVAC Drive FC 102 Operating Instructions Manual

Warnings and Alarms
ALARM 94, End of curve
Feedback is lower than the set point. This may indicate
leakage in the system. 22-50 End of Curve Function is set for
alarm.
Troubleshooting
•
Troubleshoot the system and reset the frequency
converter after the fault has been cleared.
ALARM 95, Broken belt
Torque is below the torque level set for no load, indicating
a broken belt. Parameter 22-60 Broken Belt Function is set
for alarm.
Troubleshooting
•
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. Parameter 22-76 Interval between Starts is
enabled.
Troubleshooting
8 8
•
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. Parameter 22-76 Interval between Starts is
enabled.
Troubleshooting
•
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.
Troubleshooting
•
Reset the clock in 0-70 Date and Time.
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 203, Missing motor
With a frequency converter operating multi-motors, an
under-load condition was detected. This could indicate a
missing motor. Inspect the system for proper operation.
WARNING 204, Locked rotor
With a frequency converter operating multi-motors, an
overload condition was detected. This could indicate a
locked rotor. Inspect the motor for proper operation.
