Troubleshooting

If a problem occurs, refer to the solutions provided in Table 21.

If the problem persists, contact JJS Technical Services.

Table 21. Troubleshooting Tips

Problem	Possible Cause	Solution
The detector does activate.	No batteries Depleted batteries Damaged or defective detector	Refer to Replacing/Charging the Batteries. Refer to Replacing/Charging the Batteries. Contact JJS Technical Services.
The detector immediately enters alarm mode when activated.	Sensor needs to stabilize Low battery alarm Sensor alarm Pump alarm	Used sensor: wait 60 seconds New sensor: wait 5 minutes Refer to Replacing/Charging the Batteries. Refer to Replacing a Sensor or Sensor Filter. If the sampling hose is attached, determine if it is obstructed. If not, clean or replace the pump filter. If pump alarm persists, contact JJS Technical Services.
The activation self-test fails.	General fault	Ensure that the sensors and battery pack are installed correctly and then restart the detector. If fault persists, record the error message and contact JJS Technical Services.

Table 21. Troubleshooting Tips (cont.)

Problem	Possible Cause	Solution
	The MMC/SD is not inserted	Insert the MMC/SD card. Refer to Inserting the MMC/SD Card.
	The MMC/SD card that is inserted in the detector has a storage size that is not supported by the detector	Insert an Infineon MMC/SD card that is 32 MB only
	The detector has lost communication with the MMC/SD card	Attempt the following solutions: Retry communication Insert a different Infineon MMC 32 MB Clear MMC in windows and reinsert into the detector. Contact JJS Technical Services.

Table 21. Troubleshooting Tips (cont.)

Problem	Possible Cause	Solution
The detector displays a clock error message using last recorded time.	General fault	Reactivate the detector. If the message does not display, reset the clock in user options. If the error message still displays, contact JJS Technical Services.
Detector does not display normal ambient gas reading after activation self-test.	Sensor not stabilized Detector requires calibration Target gas is present	Used sensor: wait 60 seconds New sensor: wait 5 minutes Refer to Calibration and Setting Alarm Setpoints. Detector is operating properly. Use caution in suspect areas.
Detector does not respond to pushbuttons.	Batteries are depleted Detector is performing operations that do not require user input.	Refer to Replacing/Charging the Batteries. Pushbutton function restored automatically when the operation ends.
Detector does not accurately measure gas.	Detector requires calibration Detector is colder/hotter than ambient gas Sensor filter is blocked	Refer to Calibration and Setting Alarm Setpoints. Allow the detector to acquire ambient temperature before using. Clean the sensor filter. Refer to Replacing a Sensor or Sensor Filter.

Table 21. Troubleshooting Tips (cont.)

Problem	Possible Cause	Solution
Detector does not enter alarm mode.	Alarm setpoint(s) are set incorrectly Alarm setpoint(s) set to zero Detector requires calibration	Reset alarm setpoints. Refer to Calibration and Setting Alarm Setpoints. Reset alarm setpoints. Refer to Calibration and Setting Alarm Setpoints. Calibrate the detector. Refer to Calibration and Setting Alarm Setpoints.
Detector intermittently enters alarm without any apparent reason.	Ambient gas levels are near alarm setpoint or the sensor is exposed to a puff of the target gas Alarms set incorrectly Missing or faulty sensor	Detector is operating normally. Use caution in suspect areas. Check MAX gas exposure reading. Reset alarm setpoints. Refer to Calibration and Setting Alarm Setpoints. Refer to Replacing a Sensor or Sensor Filter.
Detector automatically deactivates.	Automatic shutdown activated because of weak batteries	Refer to Replacing/Charging the Batteries.
Clock icon is flashing.	The clock has failed There is communication failure	Contact JJS Technical Services. Contact JJS Technical Services.
