- 1. All of the LCD elements display simultaneously as the detector beeps, flashes, vibrates, and activates the backlight.
- 2. The current firmware version installed on the detector displays on the LCD.
- 3. If enabled and data is entered in Fleet Manager II, a startup message (25 characters per line) displays or scrolls (depending upon length of message) on the LCD. If the startup message option is not enabled, it is bypassed during the startup test.
- 4. If the Location Logging option is enabled, the detector prompts for a number (1-999) to be entered that identifies the location (wells, plants, or other areas) where the detector is being used.

- Bump Test
- 1. Activate the detector. A bump test can be performed either during startup when the BUMP DUE NOW screen displays or when in normal operation.
- 2. Attach the calibration hose to a 0.5 l/min regulator or a demand flow regulator.
- 3. Connect the hose quick connector to the pump quick connector on the pump inlet to apply gas.
- 4. The detector should enter alarm. Verify the audible and visual alarms activate, and that the LCD readings match the span gas concentrations of the gas cylinder being used.
- 5. Disconnect the calibration hose from the detector. The detector briefly remains in alarm until the sensors clear of the test gas.
- Note
- 1. Activate the detector. A bump test can be performed either during startup when the BUMP DUE NOW screen displays or when in normal operation.

- Connecting the Gas Cylinder to the Detector
- Note
- 1. Verify the calibration gas being used matches the span concentration value(s) that are set for the detector.
- 2. Attach a 0.5 l/min regulator or a demand flow regulator to the gas cylinder.
- 3. Connect the calibration hose to the regulator on the gas cylinder.
- 4. Begin the calibration procedures. Refer to the Calibration Procedure section.
- 5. When calibration is complete, disconnect the hose from the detector and the regulator.
- 6. Ensure the gas cylinder is stored according to the manufacturer’s specifications.
- Figure 6. Connecting the Gas Cylinder to the Detector
- Calibration Procedure
- 1. Verify the calibration gas being used matches the span concentration value(s) that are set for the detector.
- Note
- 1. Activate the detector.
- 2. Ensure the sensor(s) to be calibrated is enabled in Fleet Manager II.
- 3. Verify the calibration gas being used matches the span concentration value(s) that are set for the detector.
- 4. Press and hold C while the detector performs the OFF countdown. Continue to hold C as the detector briefly deactivates.
- 1. Activate the detector.
- Note

- 8. Press C to acknowledge the warning before returning to normal operation. Refer to Troubleshooting and calibrate the failed sensor again.
- 1. After calibration is complete and the detector returns to normal operation, verify the calibration using a gas cylinder other than the one used for calibration.
- Calibrating Using the IR Link
- 1. From the PC, open Fleet Manager II.
- 2. Click Administration.
- 3. From the Administration toolbar, click Login / Logout to access the Enter Password dialog box. Enter Admin and click OK.
- 4. From the Devices toolbar, click Detector Configuration.
- 5. Activate the detector.
- 6. From Fleet Manager II, click the Calibrate button located at the bottom of the window.

- Charging the Battery
- Figure 8. Connecting the Charger Adapter
- Table 10. Connecting the Charger Adapter
- 1. Deactivate the detector.
- 2. Plug the charger into a AC outlet.
- 3. Attach the charging adapter (Figure 8.) to the charger interface.
- 4. Allow the battery to charge for 6 hours. The charging indicator flashes (low, mid, and full charge repeatedly) on the LCD while the battery is charging.
- 5. When charging is complete, the charging indicator stops flashing and displays to indicate a full charge. Remove the adapter and activate the detector.

- Replacing the Battery
- Replacing a Sensor or Sensor Filter
- Table 11. Replacing a Sensor or Sensor Filter
- Figure 9. Replacing a Sensor or Sensor Filter
- 1. Deactivate the detector.
- 2. Remove the pump inlet screw and the pump inlet. Refer to Figure 13.
- 3. Remove the six machine screws from the rear shell.
- 4. Because the pump hose is connected to the rear shell and front shell pump, carefully remove the rear shell by lifting upward and tilting to the left. The front and rear shells are laying flat side by side (Figure 10.).

- 10. Replace the particulate and/or moisture filter if required. Refer to Replacing the Pump Filters.
- 11. Re-assemble the detector and replace the PCB screws.
- 12. Replace the machine screws using 3-4 in-lbs. torque. Tighten the screws using a crisscross pattern to ensure a proper seal.
- 13. Replace the pump inlet and the pump inlet screw.
- 14. Activate the detector and calibrate the sensor(s). Refer to Calibration.
- Replacing the Pump Filters

Resetting Gas Alarm Setpoints
Table 9. lists alarm setpoints as defined by Occupational Safety and
Health Association (OSHA).
Note
Standard factory alarm setpoints vary by region.
Table 9. Sample Factory Alarm Setpoints
Note
To disable an alarm, set the alarm setpoint to 0 (zero) in Fleet
Manager II.
To change the factory-defined alarm setpoints, refer to the following in
User Options:
• Low Alarm
• High Alarm
• TWA Alarm
• STEL Alarm
Stopping a Gas Alarm
The low and high alarms stop when the ambient gas concentrations
returns to a concentration below the low alarm setpoint.
Note
If alarms are set to latch, press C to reset the alarms.
The detector computes the TWA value based on OSHA standards and
the STEL value based on a user-defined 5 to 15 minute interval. Refer to
STEL Interval
.
The TWA and STEL alarms can be stopped either by
• deactivating and then reactivating the detector, or
• clearing the TWA/STEL/MAX exposure readings. Refer to
Viewing and Clearing Gas Exposures
.
a Caution
Follow all safety procedures as defined by your
employer. Confirm with your supervisor before clearing
TWA and STEL alarms.
Sensor Alarm
The detector tests for missing or defective sensors during the startup
self-test and continuously thereafter. If a sensor fails the self-test, Err
displays above the gas type of the failed sensor. If a sensor fails, refer to
Troubleshooting
.
