5. Once all weigh modules have been installed, make sure that each is hanging
vertically (plumb).
6. Tack weld the backing plates into position. Pin or stake the nuts at both ends of the
threaded rods to prevent them from turning.
7. If the suspended tank is subject to horizontal movement, install check rods to limit
horizontal movement to less than 1/8 inch. Figures 11-5 and 11-6 show typical
check rod arrangements. Figures 11-7, 11-8, and 11-9 show typical tension weigh
module installations.
8. Mount the junction box in a location where the load cell cables can be properly
terminated in the junction box.
Do not mount the junction box on the scale.
Note: Each load cell is supplied with a standard length of cable. Do not lengthen or
shorten load cell cables in the field! Changing the length of a load cell cable will
affect the output signal from the load cell. If a cable is too long, simply coil the
excess cable and place it in or near the junction box. Nonstandard lengths of cable
can be ordered for applications that require them.
9. Connect the load cell cables to the junction box and terminate the wires according
to the wiring and color code decal on the underside of the junction box lid.
10. Connect the junction box to the scale indicator with an appropriate cable.
11. Confirm that all live-to-dead connections are flexible and securely anchored at both
the scale and the dead connection point.
