6 If the weigh bin slides on the
pins but excessive movement
exists (greater than 0.010 inch)
as shown in step 4, the weigh
bin pins will need to be
tightened. To tighten the pins,
place the weigh bin on a hard
surface and lightly tapping the top
of the pins. Each pin should be
tapped a couple of times and then
step 3 should be tried again.
7 Once the pieces are
adjusted correctly,
install the weigh bin
mount onto the load
cell. Place removable
strength (blue) Loctite on the two
screws and lightly tighten. Once
the mount is in place, adjust the
bracket until it is perpendicular to
the load cell. This can be
accomplished by looking through
the key hole slot in the weigh bin
mount and comparing the edge of
the load cell to the upper edge of
the key hole slot – they should be
parallel.
8 After the items are placed correctly, fully tighten the two screws and
torque to 10 Nm (88 in-lbs). Replace the weigh bin and calibrate/re-zero
the load cell as described in section 7.7.2.1 of the Trueblend user guide.
