Troubleshooting

If a problem occurs, refer to the solutions provided in Table 15. If the problem persists, contact BW Technologies by Honeywell.

Figure 14. Troubleshooting

Problem	Possible Cause	Solution
The detector does not activate.	Depleted battery	Charge the battery. Refer to Charging the Battery.
The detector does not activate.	Damaged or defective detector	Contact BW Technologies by Honeywell.
Detector automatically deactivates.	Automatic deactivation due to depleted battery	Charge the battery. Refer to Charging the Battery.
Detector automatically deactivates.	Lockout on Self-Test Error is enabled and a sensor(s) has failed the startup self-test	Refer to Lockout on Self-Test Error and Replacing a Sensor or Sensor Filter.
The detector enters alarm immediately when activated.	Sensor needs to stabilize	Used sensor: Wait 60 seconds New sensor: Wait 5 minutes
	Low battery alarm	Charge the battery. Refer to Charging the Battery.
	Sensor(s) requires calibration	Calibrate the sensor(s). Refer to Calibration.
	Hazardous environment	Leave the area immediately. Deactivate and reactivate the detector in a safe area that is free of hazardous gas.
The activation startup self-test fails	General fault	Contact BW Technologies by Honeywell.
The activation startup self-test fails	Sensor error	Replace the sensor. Refer to Replacing a Sensor or Sensor Filter.
Detector does not display normal ambient gas reading after startup tests.	Sensors not stabilized	Used sensor: Wait 60 seconds New sensor: Wait 5 minutes
	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 the 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 sensor(s). Refer to Calibration.
	Detector is colder/hotter than gas temperature	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 alarm.	Alarm setpoint(s) are set incorrectly	Reset the alarm setpoints. Refer to Resetting Gas Alarm Setpoints.
	Alarm setpoint(s) set to zero	Reset the alarm setpoints. Refer to Resetting Gas Alarm Setpoints.
	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 maximum gas exposure reading.
	Alarms are set incorrectly	Reset the alarm setpoints. Refer to Resetting Gas Alarm Setpoints.
	Sensor(s) requires calibration	Calibrate the sensor(s). Refer to Calibration
	Missing or faulty sensor(s)	Replace the sensor(s). Refer to Resetting Gas Alarm Setpoints.
Battery has been charging for 6 hours. Charging indicator on LCD shows the battery is still charging.	Battery is trickle charging	Battery is fully charged and is ready for operation.
Battery indicator does not display when charging.	Battery is depleted below normal levels	Charge the battery for 8 hours. If the battery indicator does not light after charging, contact BW Technologies by Honeywell.
Pump is not operating.	Diffusion cap is off or not attached correctly.	Attach diffusion cap. Ensure seal is tight.
	There is a blockage in the tubing.	Clear the blockage
	Particulate and/or moisture filter requires replacement	Replace the filter(s). Replacing the Pump Filters.
Features and options not operating as expected.	Changes in Fleet Manager II	Verify that the settings in Fleet Manager II are correct
