RKI Instruments 65-2322RKSS - Manual (Page 14)

10 • 65-2322RKSS Oxygen Transmitter
Performing the response test
1. Exhale into the bottom of the oxygen detector for a few seconds.
2. Stop exhaling into the bottom of the detector, then verify that the reading on the
voltmeter decreased from the normal reading, 434 mV.
NOTE: If the reading does not decrease, calibrate the detector as described in
“Calibration” on page 13.
3. Remove the voltmeter leads from the amplifier test points, then secure the junction
box cover to the junction box.
4. When the display reading rises above the decreasing alarm setpoint, return the
controller to normal operation.
Quarterly
Calibrate the oxygen transmitter as described in “Calibration” on page 13 of this manual.
See the calibration frequency discussion in “Calibration Frequency” on page 13 to
determine if a quarterly calibration schedule fits your needs.
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.
