•
Do a visual check to the accessories used with the module. If in doubt, replace the
accessories with known good ones.
After troubleshooting if the problem remains, contact service. Make sure you have all
necessary information of the product at hand. Describe the problem and the troubleshooting
done so far. Provide Webmin Device Information and Service logs, if requested.
5.2.1 Gas sampling system troubleshooting
•
Faults which can occur in the sampling system are: leaks or blockages in the tubing,
failure of the sampling pump or the magnetic valves, or diminishing of the flow rates
because of dirt or other matter accumulating in the internal tubing or failure of pressure
sensors.
•
Whenever suspecting the sampling system and always after having done any work on
the sampling system, check the sampling system for leakages and check the flow rate.
•
The D-fend Pro water trap should be replaced, when the 'REPLACE D-FEND' message
appears.
•
If any liquid has entered the MiniTPX measuring unit due to water trap filter failure,
contact GE service.
•
Check that the tubing inside the module is not contaminated.
Any contamination inside the tubing may indicate that the valves or sensors are
contaminated, too. This can increase a risk of faulty operation in valves or sensors. The
valves or gas sensors are not possible to clean in the field. Therefore, if you noticed any
contamination in the module tubing, send the module to GE for factory service.
NOTE: All internal tubes are mechanically fragile. Sharp bends may cause leaks and occlusions.
5.2.2 MiniOM Measuring unit troubleshooting
•
Due to the complicated and sensitive mechanical construction of the oxygen measuring
unit, no repairs should be attempted inside the unit. Instead, if the fault has been found in
the measuring unit itself, the entire module should be replaced and the faulty module be
sent to GE for repair.
•
In cases of no response to O
2
or strong drift, check the tubing for loose connections,
blockages, and leaks.
•
Check also the OM reference gas filter assembly, and replace if needed.
•
If the O
2
signal is noisy, check the measurement unit suspension and if the MiniOM tubing
has tension.
NOTE: Never apply overpressure to the O
2
measuring unit, as the pressure transducer may be
permanently damaged.
5.2.3 MiniTPX Measuring unit troubleshooting
•
The MiniTPX measuring unit can only be repaired at the factory. In case of failure, the
entire module should be replaced and the faulty module be sent to GE for repair.
5.2.4 MiniPVX Measuring unit troubleshooting
•
In case of failure, the MiniPVX unit can be replaced.
