Malfunction Possible cause Solution
Oil level in the compressor too low
even if there is refilling
No oil in the oil reservoir Refill oil, find oil imbalance
Oil level in the compressor too low
even if there is refilling
Differential pressure is too low Check whether the differential
pressure between oil reservoir and
compressor is great enough; set
differential pressure valve.
Compressor is running even though
there is not enough oil in the
compressor for a longer time.
Alarm relay not in the alarm chain Correct the connection
Alarm relay pulls in even though
compressor is at standstill
No filling possible due to missing inlet
pressure
Use "INT280-xxx" Diagnose (run
detection possible and thus no alarm
when compressor at standstill)
