INSTALLATION, ALIGNMENT, & CALIBRATION
CONVEYOR WEIGH SCALE
3-0 WEIGH SCALE ASSEMBLY
The weigh scale troughing idler must be modified prior to clamping it to SYSTEMS weigh scale frame. See
procedure on drawing # WB00-00005 Suggested Rework. Complete modification as shown.
Assemble weigh scale, independent of conveyor in the following order. See drawing # WB00-00004 Weigh Scale
Mounting Assembly for Field Installation."
Mount load cell (Cable End) to welded frame assembly with (4) 5/16 x 1 1/4 hex bolts and washers. (Mating
surfaces must be clean and free of foreign materials.) Torque bolts to 100-120 in/lb.
Place 1/2" spacer on load cell. (Mating surfaces must be clean and free of foreign materials.)
Carefully set 7 channel on 1/2 spacer centered on weigh bridge assembly. (Mating surfaces must be clean and
free of foreign materials.)
Secure channel to load cell with (4) 5/16 x 1 1/4 hex bolts and washers. Center channel side to side on weigh
scale frame. Torque bolts to 100-120 in/lb.
Note: Carefully handle weigh scale assembly to avoid shock that may damage load cell.
Center modified idler on the channel. Install V-block clamping assembly (2 places), using (4) 1/2 x 2 1/4 hex bolts
with lockwashers. Tighten securely.
4-0 WEIGH SCALE INSTALLATION and PRELIMINARY ALIGNMENT
Install complete weigh scale assembly in the intended position on conveyor. Using weigh scale as template,
carefully locate, mark, and drill (4) 9/16 dia. holes in conveyor frame.
Mount the weigh scale in position using (4) 1/2 x 2 1/4 bolts with lock and flat washers. Install 3/8" of shims
(supplied with weigh scale) below weigh scale mtg angles. Hand tighten bolts at this time. (Mating surfaces must
be clean and free of foreign materials.)
Shim the approach and retreat idlers to approximately the same height as the weigh scale idler.
Note: The approach, retreat and weigh idler must all be higher than all the other conveyor idlers.
