Diagnostics and Troubleshoo...
WARNING/ALARM 34, Fieldbus communication fault
The serial communication bus on the communication
option card is not working.
WARNING/ALARM 35, Option fault
An option alarm is received. The alarm is option-specific.
The most likely cause is a power-up or a communication
fault.
WARNING/ALARM 36, Mains failure
This warning/alarm is only active if the supply voltage to
the frequency converter is lost and 14-10 Mains Failure is
NOT set to [0] No Function. Check the fuses to the
frequency converter and mains supply to the unit.
ALARM 37, Phase imbalance
There is a current imbalance between the power units
ALARM 38, Internal fault
7 7
When an internal fault occurs, a code number defined in
Table 7.6 is displayed.
Troubleshooting
Cycle power
Check that the option is properly installed
Check for loose or missing wiring
It may be necessary to contact your Danfoss supplier or
service department. Note the code number for further
troubleshooting directions.
