6.12 Cleaning the PID lamp (X-am 5800 only)
During calibration of the PID, the gas detector identifies when there is dirt on the
lamp and displays a corresponding warning. If this warning is displayed, the lamp
window must be cleaned. Silicone-free disposable nitrile gloves and the
DrägerSensor PID cleaning set (order no. 83 19 111) must be used for this. The
cleaning set is for single use.
WARNING
Imprecise measured value (for PID)!
Contamination of the front lamp window (C) may negatively influence the measured
value.
► Do not scratch or soil the front lamp window.
To clean the PID lamp:
1. Remove the sensor.
2. Remove the sensor cap and the two filters (I).
3. Remove the plastic insert, e.g. by using tweezers to lift it out at the edge of the
sensor (II).
4. Lift out the ionisation cell by carefully inserting the tweezers on the side with the
contact pins (III). Do not allow the ionisation cell to become bent during this
process.
5. Use tweezers to remove the UV lamp. Insert the tweezers and carefully tilt them
at the edge of the housing to lift the UV lamp out of the opening (IV).
6. Hold the UV lamp on the cylindrical body and position the lamp window (C) flat
on the surface of the sandpaper. Polish the lamp window by using circular
movements (for approx. 5 to 10 seconds) and applying gentle pressure to the
surface of the sandpaper (V).
