Installation Manual
Caution:
The load cell cable must be positioned above the bellow and in front of the lift-off
protector.
Securing the threaded bush with Loctite is imperative.
•
Insert a new bellow (not shown) into the weighing module carefully, until the threaded bush (5) with
the lift-off protector (3) can be re-mounted. Make sure to use the correct tightening torques, see
Chapter 4.1.2.
•
Re-tighten the bolts (1).
•
Turn up the bolt of the lift-off protector (3) at the hex (2) to lift the vessel. Turn the bolt, until the
load cell (12) is unloaded and can be removed together with the upper thrust piece.
•
Pull the bellow (not shown) to the rear completely and revert the upper bead to the inside.
•
Insert the load cell (12).
•
Turn the bolt (1) of the lift-off protector at the hex (3) downwards slowly to lower the vessel to the
load cell. Make sure that the upper thrust piece slides into the recess of the upper plate (13).
•
Shift the reverted bellow up to adjust the lift-off protector (3); refer to Chapter 2.3.3.
•
Re-screw the stopper (6) together with the film on the lower plate (10). Make sure to use the correct
tightening torques, see Chapter 4.1.2.
•
If pivot (9) or/and roller (8) cannot be moved, the weighing module is distorted and must be adjusted:
•
Release the bolts (7).
•
Shift the stopper (9) until pivot (9) or/and roller (8) can move freely again.
•
Re-tighten the bolts (7). Make sure to use the correct tightening torques, see Chapter 4.1.2.
•
Fit the bellow, press it firmly into the groove of the upper and lower plate circumferentially, and make
sure that the transitions are flush.
