å 15, pos. 2) (this is possible only if the assembly is in
the service position).
2. Remove the yellow dummy plug (pos. 3).
3. Screw in the sensor (pos. 4) in the place of the dummy plug:
– hand-tighten initially
– then tighten it by approx. ¼ turn using the open-ended wrench (pos. 1)
4. Attach the open-ended wrench back into the protective cap.
5. Put the protective cap on the assembly. When doing so, guide the measuring cable
through the cable run (top of protective cap).
Always install the protective cap before moving the assembly to the measuring position.
The protective cap cannot be removed in the measuring position. This prevents the
sensor from being removed.
