WARNING/ALARM 34, Fieldbus communication fault
The serial communication bus on the communication
option card is not working.
WARNING/ALARM 36, Mains failure
This warning/alarm is only active if the supply voltage to
the adjustable frequency drive is lost and 14-10 Mains
Failure is not set to [0] No Function. Check the fuses to the
adjustable frequency drive and line power supply to the
unit.
ALARM 38, Internal fault
When an internal fault occurs, a code number defined in
Table 9.2 is displayed.
Troubleshooting
Cycle power
Check that the option is properly installed
Check for loose or missing wiring
It may be necessary to contact Danfoss service or the
supplier. Note the code number for further trouble-
shooting directions.
