Troubleshooting
The troubleshooting guide describes symptoms, probable causes, and recommended action for
problems you may encounter with the oxygen transmitter.
NOTE: This troubleshooting guide describes transmitter problems only. See the controller
operator’s manual for problems you may encounter with the controller.
Table 2: Troubleshooting the Oxygen Transmitter
Condition Symptom(s) Probable Causes Recommended Action
Fail
Condition
• Controller indicates
a fail condition.
• The transmitter wiring
is disconnected or
misconnected.
• The plug-in sensor is
not properly plugged
into the sockets in the
detector housing body.
• The transmitter’s zero
reading is low enough
to cause a fail
condition.
• The transmitter is
malfunctioning.
1. Verify that the transmitter wiring is
correct and secure.
2. Confirm that the plug-in sensor is
installed properly.
3. Perform a fresh air adjustment. A full
calibration is recommended
4. If the fail condition continues,
replace the plug-in sensor as
described later in this section.
5. If the fail condition continues,
contact RKI for further instruction.
Slow or No
Response/
Difficult or
Unable to
Calibrate
• Unable to accurately
set the fresh air or
zero reading during
calibration.
• Transmitter requires
frequent calibration.
Note: Under
“normal”
circumstances, the
transmitter requires
calibration once every
3 months.
Some applications
may require a more
frequent calibration
schedule.
• The calibration
cylinder is low, out-
dated, or defective.
• The flame arrestor in
the detector housing
cap is wet or clogged
with dirt or other
particulates.
• The calibration gas is
not an appropriate
concentration
• The transmitter is
malfunctioning.
1. Verify that the calibration cylinder
contains an adequate supply of a
fresh test sample.
2. Check the detector housing cap to
determine if the flame arrestor is wet
or dirty. Clean or replace if necessary.
3. Verify that the calibration gas
concentration is appropriate for the
transmitter. Zero emission air (20.9%
oxygen) is normally used for a fresh
air adjustment if the environment is
suspect and 100% nitrogen (0%
oxygen) is normally used for a zero
adjustment.
4. If the calibration/response difficulties
continue, replace the plug-in sensor
as described later in this section.
5. If the calibration/response difficulties
continue, contact RKI for further
instruction.
