The cable must

not

be in contact with the bellows inside later!

2. Slip the bellows (not shown) upwards over the mounting kit and the vessel foot (7) or

downwards over the adapter plate (5) carefully so that the mounting kit remains

accessible for mounting.

3. Loosen nut (4).
4. Turn the threaded bolt (3) of the lift-of protector upwards at the hex to lift the vessel.

Turn the threaded bolt until the load cell (6) is unloaded and can be removed

together with the upper load disc.

5. Release the gland (2) (see also the note) only until the load cell cable (1) can be

withdrawn.

6. Remove the load cell (6) from the mounting kit and take the upper load disc out of

the load cell. Socket with lower load disc (including O

ring) remain in the lower plate.

7. Insert the upper load disc into the new load cell.
8. Insert the load cell.
9. Slowly turn the threaded bolt of the lift-of protector (3) downwards at the hex to

lower the vessel onto the load cell. Make sure that the upper load disc slides into the

recess of the upper plate.

10. Pull the load cell cable (1) through the borehole in the upper plate provided for this

purpose and the cable gland (2) and insert it in stress-relieved position (loop).

11. Tighten the cable gland (2).
12. Adjust the internal lift-of protector; refer to Chapter

3.4.3

.

13. Fit the bellows, press it irmly into the groove of the upper and lower plate

circumferentially, and make sure that the transitions are lush.
