9.6 Exchange or shorten cable/rod
The cable or rod (meas. part) of the probe can be shortened, if neces-
sary. To loosen the rod or cable you need a fork spanner with spanner
width 13.
1. Loosen the rod or cable by applying a fork spanner to the flat
surfaces (SW 13), provide counterforce with another fork spanner
(SW 13)
2. Unscrew the loosened rod or cable manually.
3. Place the enclosed new double washer onto the thread.
Caution:
Make sure that the two components of the double washer remain
together.
4. Screw the new rod and the new cable manually to the thread on
the process fitting.
5. Exert counterforce with the second fork spanner and tighten the
or or cable on the flat surfaces with a torque of 15 Nm (11 lbf ft).
Fig. 32: Exchange cable or rod
Information:
Please keep the stated torque so that the max. tensile strength
remains.
The rod or cable of the probe can be shortened individually.
1. Mark the requested length with mounted measuring rod.
2. Cable: Loosen the three pins on the gravity weight
Cable ø 4: 6 hexagon 3
Cable ø 6, cable ø 8: hexagon 4
3. Cable: remove the pins
4. Cable: Pull the cable out of the gravity weight
5. Shorten the cable/rod with a cut-off wheel or metal saw at the
marking. Take note of the specifications in the following illustration
when shortening the cable.
