Make sure the corner of the frames are fully and rigidly supported. If neces-
sary, use metal shims to ensure a good, level support.
Once the modules are properly installed, use the connector bolts, bevel
washers, and nuts to firmly attach each module together. Refer to Figure 8.
Loosen all check bolts - 4 per module
Remove the nuts from the hold down bolts; lower the bolts; then, replace the
nuts on the bolts, so they remain on the holding block on the frame.
Adjust the check bolts to a maximum of 3/16" clearance. Refer to Figure 3.
Install the optional bulkheads on each end of the scale.
If the bulkheads are from Weigh-Tronix, use (4) 3/4 - 10 x 2 1/2" bolts, bevel
washers, and nuts supplied by Weigh-Tronix. Refer to Figure 4.
If other than Weigh-Tronix bulkheads are used, ensure the proper clearance
between the scale platform and the bulkhead. Weigh-Tronix will not be
responsible for error caused by other bulkheads.
Once the bulkheads are properly installed, prepare the ramps at each end of
the scale. The ramps must be straight and level, for a minimum of 10 feet at
each end of the scale.
The ground rod must be installed as close as possible to the scale module
at the opposite end and same side as the junction box. Connect the ground
rod to the scale module frame using the supplied ground strap. Refer to
Figure 5. One ground rod should be installed for each end of a scale plus
one ground rod for each junction between modules.
Use the interconnecting cables to connect the modules together and to
connect the scale to the indicator. Leave the protective cover on the unused
connector. Apply nonconductive grease inside the removed protective caps
and if needed, apply nonconductive silicone grease on the cable before
connecting it to the box. Refer to Figure 9 for 2 module installations and
Figure 10 for 3 module installations.
