START-UP
7.4.1 Installing the SR-unit on the measuring probe
The measuring probe can be fitted on the SR-unit already installed. To ease handling and
to avoid unnecessary mechanical stress on the SR-unit, the flange fixture can be removed
beforehand and the measuring probe installed on it separately.
Removing the flange fixture (optional)
1 If the flange fixture is no longer swiveled open from the previous work steps:
▸ Loosen the 4 quick-release fasteners on the SR-unit enclosure.
▸ Swivel the flange fixture out.
2 Pull the hinge bolt on the left of the enclosure upwards out of the hinge and remove the
flange fixture.
3 Fit the measuring probe on the flange fixture just removed as described in the following.
Installing the measuring probe
The installation procedure is identical for all measuring probe versions. The fixing parts are
supplied with the GM35 measuring system.

1 Place 10 cup springs in each case, with the front ends facing each other, that is, 5 pairs,
on the three threaded pins on the flange fixture of the SR-unit. The sectional view (
see
page 81
) shows the exact arrangement.
2 Pull the sealing ring over the device flange and hang it loosely over the measuring probe
where it is then ready for use.
3 Carefully position the measuring probe with the device flange on the three threaded pins
fitted with cup springs on the flange fixture without damaging the threads.
4 Fit the centering discs and tighten the nuts using a 19 mm wrench so that the cup
springs are pressed together slightly.
