Fairbanks VSX SERIES TRUCK SCALE - Manual (Page 33)

Section 3: Wiring
04/12 33 51173 Rev. 8
GROUNDING THE SCALE, CONTINUED
The 117 VAC SVP Unit ( 65056 ) must be connected to a known good ground at the
instrument location.
 Use a voltmeter to test the electrical power source available for the Neutral-to-
Ground voltage level
▪
It must be
0.2VAC or LESS
.
 If unsure about the voltage, or the testing reveals a higher than acceptable
level ( 0.2VAC MAXIMUM ), install a separate ground rod at the SVP 65056
location.
 Use braided cable or #8 AWG wire to make the SVP to ground rod
connection.
DATA RECORDING
1. Record the scale serial numbers from the tag.
2. Record the instrument, SSC, PPS, and load cell serial numbers.
3. Keep a copy of the sheet in the customer file.
 Use Appendix
II
for additional information.
Full Electronic Scales are designed to provide protection from moisture.
 The load cells are calibrated with the cable attached, and therefore the cable
should NOT be cut.
 The cable is connected directly to the SSC through a sealed bushing which
MUST be tightened with pliers to keep water/moisture out of the box.
 All cabling should have a “drip loop” at the cell or box entry location to help
prevent water entry.
 On all boxes, the black plastic fittings have O-rings that can be forced out of
position if the bushing itself is not tight.
▪ To prevent this, first tighten the inner nut securing the bushing in the hole, then
insert cable and carefully tighten gland with pliers until it is very snug.
▪ Do not over-tighten where bushing ‘turns.
 All box covers MUST be secured with ALL latches secured properly for
protection against moisture.
