3.1 Mounting instructions
The reference plane for the measuring range is the lower edge of the
transducer.
Makesurethataminimumdistancefromthereferenceplane-the
so-calleddeadzone,inwhichmeasurementisnotpossible-is
maintained.Theexactvalueofthedeadzoneisstatedinchapter
"Technical data".

module PLICSCOM
5.1 Insert display and adjustment module
The display and adjustment module can be inserted into the sensor
andremovedagainatanytime.Itisnotnecessarytointerruptthe
voltagesupply.
Proceed as follows:
1. Unscrew the housing lid
2. Place the display and adjustment module in the desired position
ontheelectronics(youcanchooseanyoneoffourdierentposi-
tions-eachdisplacedby90°)
3. Press the display and adjustment module onto the electronics
and turn it to the right until it snaps in
4. Screw housing lid with inspection window tightly back on
Disassemblyiscarriedoutinreverseorder.
The display and adjustment module is powered by the sensor, an ad-
ditional connection is not necessary.
