DANGER
A falling loading platform can result in death, severe injury or damage to
equipment depending on exposure.
Insert the oscillation housing (12) into the load cell (3). The arrow on the front of
the load cell indicates the direction of measurement.
Install the retaining ring (11) in the groove of the oscillation housing (12).
Lie the spacer bar (2) on the base plate (1) so that both holes are aligned with the
threaded holes in the base plate (1) and so that it is even. The spacer bar (2) is
asymmetrical.
Put the load cell (3) on the spacer bar (2) using 2x hexagon bolts (5) and 2x
washers (4).
Tighten the 2x hexagon bolts (5) to 23 Nm torque. Do not use the load cell as
leverage when tightening the bolts as this can cause damage to the load cell.
Smear the ball surface of the oscillation bolt (16) with bearing grease and insert it
into the oscillation housing (12).
Set the head plate (17) on the oscillation bolt (16).
Screw the counter-sunk bolt (8) into the base plate (1) and tighten the lower nut
(6).
Loosen nut (7) from nut (6), turn it upwards on the threads and tighten against
the head plate (17). This optimally centers the head plate over the base plate,
pressure is relieved on the load cell and it is protected against overloading during
the installation.
