Parker domnick hunter trained, qualified and approved engineer.
Fault
Power connected but the status
indicators and display (analyser only) is
not illuminated.
No / Low gas outlet pressure
High Oxygen concentration.
Low inlet pressure
Excessive noise or vibration
High outlet pressure.
Moisture in the gas at the outlet of the
generator.
Reduced flow at the outlet of the
generator.
Probable Cause
The electrical power to the generator is not
connected.
The electrical supply fuse is blown.
The controller ribbon cable is not connected.
External leak.
Internal leaks.
The pressure of the compressed air supply is
low.
The generator requires a service.
Defective Oxygen cell.
Leak in system piping.
The pre-filtration within the system is
approaching the end of its operational life.
The pretreatment dryer is being overflowed or
is operating at a reduced system pressure.

Open the access door and check all connection
points for leaks.
Repair as necessary.
Check the service shedules for the filters and
perform the required service.
