RKI Instruments 65-2335RK - Manual (Page 14)

10 • 65-2335RK CO Transmitter
NOTE: If the readings are not within ± 10% of the correct response reading, calibrate the
affected transmitter(s) as described in “Calibration” on page 14.
3. Turn the regulator’s on/off knob clockwise to close the regulator.
4. Unscrew the regulator from the calibration cylinder.
5. Unscrew the calibration cup from the CO detector.
6. Remove the voltmeter leads from the amplifier test points.
7. Reinstall the junction box cover.
8. When the controller display reading falls below the alarm setpoints, return the
controller to normal operation.
9. Store the components of the calibration kit in a safe place.
Quarterly
Calibrate the CO transmitter as described in “Calibration” on page 14 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 CO 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 CO Transmitter
Condition Symptom(s) Probable Causes Recommended Action
Fail Condition Controller indicates a
fail condition. • The transmitter wiring
to the controller is
disconnected or
misconnected.
• The wiring from the
detector to the
amplifier is
disconnected or
misconnected.
• The plug-in sensor is
not properly plugged
into the four-socket
pattern 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 to the
controller is correct and secure.
2. Verify that the wiring from the detector
to the amplifier is correct and secure.
3. Confirm that the plug-in sensor is
properly installed.
4. Perform a zero adjustment. A full
calibration is recommended.
5. If the fail condition continues, replace
the sensor as described later in this
section.
6. If the fail condition continues, contact
RKI for further instruction.
