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
•
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 13 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.
Recommended action
1.
Verify that the calibration cylinder contains an adequate supply of a fresh test sample.
2.
Confirm that you are using the correct calibration cup and regulator for your detector type. See
Table 2 on page 14 for a list of the required calibration cups and regulators.
3.
Check the plug-in sensor face and remove any particulate contamination if necessary.
