Maintenance
This section describes maintenance procedures. It includes details on preventive maintenance,
troubleshooting, and component replacement procedures.
Preventive Maintenance
This section describes a preventive maintenance schedule to ensure the optimum performance of
the combustible gas detector. It includes daily and biannual procedures.
Daily
Verify a display reading of 0% LEL at the controller. Investigate significant changes in the
reading.
Biannually
Calibrate the detector every six months as described in “Calibration” on page 15.
Troubleshooting
The troubleshooting guide describes symptoms, probable causes, and recommended action for
problems you may encounter with the combustible gas detector.
NOTE:
This troubleshooting guide describes detector problems only. See the controller
operator’s manual for problems you may encounter with the controller.

Recommended Actions
Fail Condition
• Controller indicates
a fail condition.
• The detector wiring
is disconnected or
misconnected.
• The detector zero
signal is low enough
to cause a fail
condition.
• The detector was
exposed to gas
during its 2 minute
warmup period.
• The detector is
malfunctioning.
1. Verify that the detector wiring is
correct and secure.
2. Calibrate the detector.
3. Restart the controller and ensure
that the detector’s environment is
free of combustible gas during
the warmup period.*
4. If the fail condition continues,
replace the detector.
5. If the fail condition continues,
contact RKI for further
instruction.
