2.5 Turning the transmitter housing and local display
(compact version)
In the compact version the transmitter housing and the local display can be rotated in
steps of 90° relative to the sensor. This enables the unit to be adapted to suit the
various mounting positions in the pipe.
Note!
For instruments with EEx d/de approval the procedure for rotating the instrument
is different than that described here and is given in the Ex supplement to this manual.
Turning the transmitter housing
1. Loosen the two fixing screws of the transmit-
ter bayonet catch (appr. 2 turns).
2. Turn the bayonet catch of the transmitter as
far as the screw slits.
3. Lift the transmitter housing to the stop.
Note!
During servicing (and only then) the trans-
mitter housing can be separated from the
sensor. To do this the corresponding mark-
ing notches on the side of the bayonet
flanges should be brought into alignment.
Do not damage the cable to the sensor
when lifting the transmitter housing.
4. Turn the transmitter housing into the desired
position. Engage the bayonet catch and
re-tighten the two screws.
