Troubleshooting

If the Status Indicator is Red

Sufficient vacuum is normally built up during the initial start-up and is
maintained by turning on the vacuum pump whenever triggered by the
vacuum sensor.
If the vacuum cannot be reached, or is lost faster than expected during
operation, the vacuum degasser will be forced into an error state.
Approximately 8 to 16 minutes after turning on the vacuum pump without
reaching its normal operation modes the error LED is turned on and the
vacuum pump and the solenoid will be disabled.
The error condition can be reset by turning the vacuum degasser off and on
again. If the error condition persists the error will occur again after another 8
to 16 minutes.
The following described failure conditions will appear during the start-up
procedure before the red error LED is turned on. Every power cycling of the
degasser will give you 8 to 16 minutes of time to diagnose the failure
conditions described on the following pages:
