Maintenance
7. Put the UV lamp back in. Make sure that the metal surfaces (D) of the lamp are
aligned so that they come into contact with the spring contacts in the sensor
housing (VI). Apply gentle pressure to the lamp window to push the UV lamp into
the opening, making sure not to scratch it or get dirt on it.
8. To put the ionisation cell back in place, insert the contact pins into the openings
of the sensor printed circuit board and carefully push in until the cell lies flat on
the lamp window. Do not allow the ionisation cell to become bent.
9. Position the plastic insert.
10.Position a new cotton filter (B; from the PID cleaning set).
11.Position a new water protection film (A; from the PID cleaning set) with the shiny
side facing up.
12.Position the sensor cap (with the opening over the ionisation cell). The sensor
cap must latch into place.
13.Install the sensor.
14.Carry out zero calibration.
15.Carry out the span calibration.
If the warning persists after cleaning and the sensor cannot be calibrated, the PID
must be replaced.
6.13 Exchange the device components
WARNING
Loss of explosion protection!
Incorrect assembly or disassembly may compromise IP or explosion protection.
► Make sure that all seals are in their correct positions.
► The seals and sealing surfaces may not be damaged and must be clean.
6.13.1 Opening the gas detector
NOTICE
Loss of data and damage to the gas detector!
If the housing is opened when the gas detector is switched on, this may cause a
loss of data and damage to the gas detector.
► Turn off the gas detector before opening the housing.
NOTICE
Damage to components!
The gas detector includes components that may become charged.
► Before opening the gas detector to replace the sensor, make sure the person
carrying out the work is grounded in order to avoid damage to the gas detector.
An ESD workplace (ElectroStatic Discharge), for example, will ensure the
grounding takes place.
Equipment:
– Torx T6 screwdriver for the housing
– Torx T8 screwdriver or Allen key (2 mm) for the power pack
