Troubleshooting

If a problem occurs, refer to the solutions in the Troubleshooting section.
If the problem persists, contact JJS Technical Services

Table 15. Troubleshooting

Problem	Possible Cause	Solution
Startup
Startup	Depleted battery	Charge battery. Refer to Charging the Battery
Startup	Damaged or defective detector	Contact JJS Technical Services.
The detector enters alarm immediately when activated.	Sensor needs to stabilize	Used sensor: wait 60 seconds New sensor: wait 5 minutes (The oxygen sensor in the X3 needs 60 minutes to stabilize)
	Low battery alarm	Charge battery. Refer to Charging the Battery.
	Detector requires calibration	Calibrate the detector. Refer to Calibration.
	Hazardous environment	Leave the area immediately. Deactivate and reactivate in a safe area that is free of hazardous gas, in an atmosphere of 20.9% oxygen.
The activation self-test fails.	General fault	Contact BW Technologies by Honeywell.
The activation self-test fails.	Sensor failure	Replace the sensor. Refer to Replacing a Sensor or Sensor Filter.
Detector automatically deactivates during startup.	Battery power too low to operate	Charge battery. Refer to Charging the Battery.
	Force Calibration When Overdue option is enabled and calibration is not attempted	Calibrate the sensor(s) immediately. Refer to Calibration.
	Force Bump When Overdue option is enabled and a bump test is not attempted	Bump test the sensor(s) immediately. Refer to Bump Test.
Detector Operation
Detector does not display expected gas readings after activation self-test.	Sensor not stabilized	Used sensor: wait 60 seconds New sensor: wait 5 minutes (The oxygen sensor in the X3 needs 60 minutes to stabilize)
	Sensor(s) requires calibration	Calibrate the sensor(s). Refer to Calibration.
	Target gas is present	Detector is operating properly. Use caution in suspect areas.
Detector does not respond to pushbutton.	Battery is depleted	Charge battery. Refer to Charging the Battery.
Detector does not respond to pushbutton.	Detector is performing operations that do not require user input	Pushbutton operation restores automatically when the operation ends.
Detector does not accurately measure gas.	Sensor(s) requires calibration	Calibrate the sensors. Refer to Calibration.
	Detector is colder/hotter than ambient gas	Allow the detector to attain ambient temperature before use.
	Sensor filter is blocked	Replace the sensor filter. Refer to Replacing a Sensor or Sensor Filter.
Detector does not enter into alarm.	Alarm setpoint(s) defined incorrectly	Reset alarm setpoints. Refer to Factory Gas Alarm Setpoints and Sensor Configuration.
	Alarm setpoint(s) set to zero	Reset alarm setpoints. Refer to Factory Gas Alarm Setpoints and Sensor Configuration.
	Detector is in calibration mode	Complete the calibration procedure.
Detector intermittently enters alarm without reason.	Ambient gas levels are near alarm setpoint or the sensor is exposed to a puff of the target gas	Detector is operating normally. Use caution in suspect areas. Check the peak (maximum) gas exposure reading.
	Alarm setpoints defined incorrectly	Reset alarm setpoints. Refer to Factory Gas Alarm Setpoints and Sensor Configuration.
	Detector requires calibration	Calibrate the sensors. Refer to Calibration.
	Missing or faulty sensor(s)	Replace the sensor. Refer to Replacing a Sensor or Sensor Filter.
Features and options are not operating as expected.	Changes have been made in Fleet Manager II	Verify settings in Fleet Manager II are correct.
Charging
Battery has been charging for 3+ hours (XT model) or 6+ hours (XL-X3 models). The charging indicator on the detector LCD shows the battery is still charging.	Battery is trickle charging	Battery is fully charged and ready for operation.
Battery indicator does not display when charging.	Detector is depleted below normal levels	Charge the battery for 8 hours. Detector LEDs may light during first 5 hours. This is normal. If the battery indicator does not light after charging for 8 hours, contact BW Technologies by Honeywell.
When detector is activated after charging, the battery indicator does not display.	Battery is defective	Contact BW Technologies by Honeywell.
