WARNING
Disconnect power before proceeding.
Troubleshooting:
Check fan resistance.
Check soft charge fuses.
IGBT thermal sensor.
ALARM 30, Motor phase U missing
Motor phase U between the frequency converter and
the motor is missing.
Turn off the frequency converter and check motor
phase U.
WARNING
Disconnect power before proceeding.
ALARM 31, Motor phase V missing
Motor phase V between the frequency converter and
the motor is missing.
Turn off the frequency converter and check motor
phase V.
WARNING
Disconnect power before proceeding.
ALARM 32, Motor phase W missing
Motor phase W between the frequency converter and
the motor is missing.
Turn off the frequency converter and check motor
phase W.
WARNING
Disconnect power before proceeding.
ALARM 33, Inrush fault
Too many power-ups have occurred within a short
time period. Let unit cool to operating temperature.
WARNING/ALARM 34, Fieldbus communica-
tion fault
The fieldbus on the communication option card is not
working.
WARNING/ALARM 35, Out of frequency
range:
This warning is active if the output frequency has
reached the high limit (set in par. 4-53) or low limit
(set in par. 4-52). In
Process Control, Closed Loop
(. 1-00)
this warning is displayed.
WARNING/ALARM 36, Mains failure
This warning/alarm is only active if the supply voltage
to the frequency converter is lost and par.14-10
Mains
Failure is NOT set to OFF. Check the fuses to the fre-
quency converter
ALARM 38, Internal fault
It may be necessary to contact your Trane supplier.
