Technical information

An incorrect amount of packing under the
loadcell will cause inaccurate batch
weighing. The following checks must be
made:
Check top edge of both link arms (31)
are horizontal within 2mm (1/16"). If
not, adjust loadcell packing.
Check link shaft (32) is clear of holes in
hopper cradle either end. Inspect from
both inside and outside engine
compartment. Correct by adjusting
loadcell packing.
Check link arm needle roller bearings
(33) for excessive wear. These may
need replacing to ensure complete
accuracy of weigh mechanism.
When lowering hopper, loadcell striker
(30) must make contact with loadcell
striker guide (26) before coming to rest
on the loadcell. If it does not, reduce
packing under loadcell and recheck
level of link arms (31).
To increase gauge reading at low
loads, increase packing under loadcell.
When all these checks have been made,
use known weights evenly distributed in
hopper to check correct gauge reading
progressively through its range.
Check loadcell striker (30) is at the correct
angle of 25 degrees to hopper cradle (34).
Adjustment can be made by altering
loadcell striker packing (35) until correct
angle is obtained.
To increase gauge reading at high loads,
increase loadcell striker packing (35).
