FC ALARM MOTOR OVERTEMPERATURE
The car drive hoisting machine has exceeded its operating temperature
C1:The heat dissipation is not working
A1:Check operation of heat dissipation device (for example, fan or forced
ventilation) if present
C2:Too hot ambient air temperature (for example, direct sunlight at glass
shaft)
A2:Wait for cool down
C3:The temperature feedback signal is faulty
A3:Check general wiring to temperature sensor.Check operation of
temperature sensor.
C4:Too intensive operation (for example, too many trips per time unit)
A4:Wait for cool down
2317
FC ALARM MOTOR UNDERLOAD
C1:FC (Closed Loop) Motor underload
A1:Check gear box
2324
FC ALARM HISTORY MAYBE LOST
C1:The values in the Fault history, MWh-counters or operating day/hour
counters might have been changed in a previous mains interruption.
A1:Does not need any actions. Take a critical attitude to these values
2328
FC ALARM APPLICATION CHANGE FAILED
C1:Application change failed
A1:Choose the application again and press the enter button
2330
FC ALARM UNBALANCED CURRENTS
C1:Unbalanced current fault, the load on the segments in not equal.
A1:Replace frequency converter
2342
FC ALARM TOO HIGH OR TOO LOW SPEED AT TARGET PHS
C1:FC (Closed Loop) Wrong speed at target (last PHSx rising edge)
A1:Check flags position Check PHS1/2 sensors. Redo learning trip
2345
FC ALARM CONVERTER OVERTEMPERATURE
C1:Temperature of heatsink over programmable temp. value (for
example, +40?C)
A1:Check the cooling air flow and the ambient temperature
2349
FC ALARM STATE MACHINES SUPERVISION
C1:FC (Closed Loop) Internal logical error
A1:Check FC states. If error occurs repeatedly replace FC
2354
FC ALARM BRAKING RESISTOR OVERTEMPERATURE
C1:Brake resistor bimetal temperature switch. The brake resistor temp
monitoring circuit has opened. If elevator is executing a trip it can
usually be finished. New trip cannot be started before bimetal temp
switch is closed again (5 min.)
A1:Check brake resistors temperature. Check wiring and/or the bimetal
temperature switch itself
