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.
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.

6.2 Hydrocarbon level is a above 0.1ppm.
Indication
Poor quality results, downstream
monitoring
Possible fault / Condition
The controller has reverted to its default setup.
The temperature is over range. The controller configuration
does not match the thermocouple.
The temperature is under range. The controller
configuration does not match the thermocouple.
The input sensor is open circuit.
Possible fault / Condition
The generator is not powered
The compressed air supply is contaminated.
The Heater / Catalyst is faulty
Excessive flowrate.

Action
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.
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.
Contact Parker Hannifin.
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.
