6 Troubleshooting
In the unlikely event that a problem occurs on the equipment, this troubleshooting guide can be used to identify the probable cause and remedy.
6.1 Fault Indicators
Under certain fault conditions the following messages may be displayed on the controller.
6.2 Hydrocarbon level is a above 0.1ppm.
Troubleshooting should only be attempted by competent personnel. All major repair, and calibration work should be
undertaken by a Parker Hannifin trained, qualified and approved engineer.
Message
Possible fault / Condition
Action
The controller has reverted to its default setup.
Contact Parker Hannifin.
The temperature is over range. The controller configuration
does not match the thermocouple.
Contact Parker Hannifin.
The temperature is under range. The controller
configuration does not match the thermocouple.
Contact Parker Hannifin.
The input sensor is open circuit.
Contact Parker Hannifin.
Indication
Possible fault / Condition
Action
Poor quality results, downstream
monitoring
The generator is not powered
Check the following:
1
the generator is connected to a 'Live' supply.
2
the ON / OFF switch in is the 'I' position.
3
the fuse in the IEC320 socket and the fuse in
the plug of the supply cable (UK only).
4
the electrical supply cable is not damaged.
Contact Parker Hannifin.
The compressed air supply is contaminated.
Carefully open the drain on the inlet filter on the rear
of the generator. If condensate flows from the drain
the compressed air supply is not the required
quality.
A small compressed air dryer should be installed
upstream of the generator.
Contact Parker Hannifin.
The Heater / Catalyst is faulty
Contact Parker Hannifin.
Excessive flowrate.
Ensure that a high purity flow meter is installed
down stream of the generator as recommended in
section three of this manual. Refer to the technical
specification for maximum flow rate data.
