2.
Align and level the idler in the weighing area by raising or lowering the weigh blocks
in their mountings.
The weighing area includes the scale and at least two idlers on each side of the
scale. For conventional flat idler roll conveyors, two additional idler rolls should
be included in the alignment procedure.
3.
Adjust idlers vertically until they are all within ±0.75 mm (1/32") of each other.

Stretch a line across the top surface of each idler roll in the scale area
approximately 25 mm (1") from each end of each side idler roll and at the centre
roll.
Use good quality wire [0.5 mm (0.020") diameter] or equivalent nylon line to
check for alignment. The wire or string aligning lines must be able to withstand
sufficient tension to eliminate sag in the line.
4.
Check that the idlers are centered and squared to the conveyor as in step 6 of the
installation procedure on page 15.
Off-center or off-square installation can result in poor belt tracking and scale
Note:
inaccuracy.
5.
Tighten the weigh blocks' mounting bolts (34 to 40.8 Nm or 25 to 30 ft lbs).
6.
Install the speed sensor as described in the speed sensor instruction manual.
7.
Connect the speed sensor and the MCS to the belt scale integrator. Refer to the
integrator manual and its system interconnection diagram.
