Troubleshooting
The troubleshooting guide describes symptoms, probable causes, and recommended
action for problems you may encounter with the toxic detector.
NOTE: This troubleshooting guide describes detector problems only. See the controller
operator’s manual for problems you may encounter with the controller.
Fail Condition
Symptoms
• The controller indicates a fail condition.
Probable causes
• The detector wiring is disconnected or misconnected.
• The plug-in sensor is not properly plugged into the socket in the detector housing
body.
• The detector’s zero reading is low enough to cause a fail condition.
• The detector is malfunctioning.
Recommended action
• Verify that the detector wiring is correct and secure.
• Confirm that the plug-in sensor is installed properly.
• Perform a zero (fresh air) adjustment. A full calibration is recommended.
• If the fail condition continues, replace the plug-in sensor as described later in this
section.
• If the fail condition continues, contact RKI for further instruction.
Slow or No Response/Difficult or Unable to Calibrate
Symptoms
• The detector responds slowly or does not respond during the monthly response test.
• Unable to accurately set the zero or response reading during the calibration
procedure.
• The detector requires frequent calibration.
NOTE: Under “normal” circumstances, the detector requires calibration once every three
months. Some applications may require a more frequent calibration schedule.
See “Calibration Frequency” on page 11 for a discussion of the calibration
frequency.
Probable causes
• The calibration cylinder is low, out-dated, or defective.
• The incorrect calibration cup or regulator is being used.
• The plug-in sensor face is blocked with dirt or some other particulate contamination.
• The detector is malfunctioning.
