Mount the modules directly across from each other using a square or common reference point.
The mounts should also be centered between the closest idlers on either side of the weighing
idler(s). Once centered and squared tighten down the mounting bolts for the left and right
modules.
You can now place the modified idler on top of the mounting pads. Make sure the belt direction
of the idler is correct. Assemble the idler hold down clamps with the carriage bolts and hardware
supplied. Only finger tighten at this point. Loosen the mounting bolts on the end of the load
cells with the rigid mount on them. Just enough to allow the mounting pad to settle and come
into full contact with the inverted angle of the CEMA idler.
For HY25 dual idler installations repeat this process for the second idler.
Note that if the structure is truly flat and square the idler(s) that have now been mounted on the
modular scale assemblies is approximately 1/8” higher than the adjacent idlers. This is not
always the case but the following instructions are based on this assumption. Adjustments and
shim size references may need to be different in your specific application.
Now align the weigh idler with the three idlers on either side of the scale using the fish line and
shims provided. Perform the instructions following and refer to the diagram below.
1) Loosen the two idlers before and after the scale.
2) Shim the +2 and -2 idlers up 3/16 of an inch, center them on the stringer, and re-tighten the
bolts.
3) Stretch three fish lines across the idlers centered on the +/- 2 roller center marks.
