Performing the response test
1. Turn the regulator’s on/off knob counterclockwise to open the regulator. Gas will
begin to flow.
2. Allow the gas to flow for one minute.
3. Verify that the reading is within ± 20% of the gas concentration.
NOTE: If the readings are not within ± 20% of the gas concentration, calibrate the
detector as described in the Calibration section of this manual.
4. Turn the regulator knob clockwise to close the regulator.
5. Unscrew the regulator from the calibration cylinder.
6. Unscrew the calibration cup from the detector.
7. When the display reading falls below the alarm setpoints, return the controller to
normal operation.
8. Store the components of the calibration kit in a safe place.
Quarterly
Calibrate the detector as described in the Calibration section of this manual.
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.
Table 2:Troubleshooting the Combustible Gas Detector
Condition Symptom(s) Probable Causes Recommended Action
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 is
malfunctioning.
1. Verify that the detector wiring is
correct and secure.
2. Calibrate the detector.
3. If the fail condition continues, replace
the detector.
4. If the fail condition continues, contact
RKI for further instruction.
