mics protection disc (5/3) which protects the current
feed-through against contamination.
3.3.4 Assembly of the Sensor
The sensor is reassembled in the reverse order as for
disassembly which is described in Section 3.3.2.
When inserting the anode ring (5/4) you must make sure
that a clearance of 1 mm remains between the wings of
the ignition aid (5/2) and the wall of the housing. Moreo-
ver, make sure that the anode ring is lying snug on the
ceramics disc.
When inserting the cathode plate (5/5) into the housing
the wings of the ignition aid (5/2) must not be bent.
Therefore insert slowly and carefully.
3.3.5 Assembly of the Electronics Assembly
How to proceed:
1) Place the magnet assembly on the sensor.
2) Push the electronics assembly over the magnet
assembly and the sensor, and turn slightly as requi-
red until the correct orientation between electronics
assembly and sensor has been found. When the
electronics assembly has been placed as required,
the black magnet housing is fully surrounded by the
housing of the PEG100.
3) Retighten the cross head screws at the rear of the
PEG100.
