    Operation Activating the pump To activate the pump in (normal) measuring mode: 1. Place, align and tighten the pump adapter on the thread port on the top cover. Check that the pump adapter is mounted correctly. Avoid bending the pump adapter.
  • Page 24: Deleting (application) Peaks

    Operation If the measuring range is exceeded significantly at the CatEx channel (very high concentration of flammable materials), a blocking alarm is triggered. This CatEx blocking alarm can be acknowledge by switching the gas detector off and then on again in fresh air. X-am 8000 only: This does not apply in the case of an activated over range for methane.

    Operation The wizards are only available for X-am 8000. For the DrägerSensors XXS CI2, COCI2, O3 as well as amine and odorants, there are no wizards for confined spaces and leak searching, as these materials can not be pumped (properly) through tubes. In addition to the materials listed above, there may also be other materials for which there are no flushing times available in the gas detector.
  • Page 27 Operation 2. Mount the pump adapter to the gas detector. Make sure that both guide pins are in the correct grooves. Check that the pump adapter is mounted correctly. If the pump adapter is mounted correctly, the leak test starts automatically. If the leak test does not start, the gas detector is not ready for use.
  • Page 28: Measurements With Wizards

    Operation 2. Remove the pump adapter. ✓ The pump is flushed and the gas detector automatically switches to diffusion mode. 4.11 Measurements with wizards The gas detector has wizards for easily preparing the measurements and for measurement displays optimised for the measurement. There are wizards for the following applications: –...
  • Page 29: Carrying Out Leak Searches With The Wizard

    Operation The displayed flushing time shows the minimum wait time required for the measurement gas to reach the sensor from the sampling location in an ideal scenario. This applies to the use of a Dräger sampling hose (fluoroelastomer, brand new, dry, clean) with an internal diameter of 3 mm. Other fixtures (e.g. pre-tube) extend the minimum wait time and must also be taken into consideration.

    Maintenance If the specified temperature range (5 to 35 °C) is not reached or is exceeded, charging stops automatically. This extends the charging time. After a return to the temperature range, charging continues automatically. The gas detector can be switched on again in the charging cradle and is then supplied with electrical current during operation.
  • Page 49 Maintenance To add a physical sensor, follow the same procedure used to exchanging a sensor. However, instead of the a sensor, there is a sensor placeholder in sensor damper. When the sensor type is exchanges, the sensor damper must also be exchanged accordingly.
  • Page 50 Maintenance 6. Rotate the gas detector and carefully lift it out of the upper cradle. 7. Exchanging the EC sensors: a. Remove the sensor sealing plate from the EC sensors. b. Place the special tool on the trough. Using the accompanying special tool (1), carefully lift out the desired EC sensor (2).
  • Page 51 Maintenance WARNING X-am 8000: Risk of incorrect measured values! In pump mode and after calibration, incorrect measured values may be returned if the following sensors are used on the sensor positions EC2 and EC3. ► The DrägerSensors XXS O3, XXS Cl2 and XXS COCl2 may only be used in sensor position EC1.
  • Page 52: Cleaning The Pid Lamp (x-am 8000 Only)

    Maintenance Next steps: ► After every sensor exchange, the fresh air calibration / zero-point calibration must first be carried out followed by the span calibration (multi-gas or single- gas). ► For the XXS O , Dräger recommends testing the alarm feature with a suitable test gas after the fresh air calibration.
