10 ELECTRONIC SCALES AND LOADCELLS
CAUTION: DO NOT WELD ON EQUIPMENT.
Scales must be disconnected from
power source and/or battery before welding to prevent damage to micro-processor and
strain gauges.
CAUTION: DO NOT LIFT OR RAISE BALEWAGON FROM LOAD CELL
LOCATIONS.
Damage to load cells will result, causing false scale readings.
DO NOT
DRIVE OR TOW UNIT AT HIGH SPEED IN BUMPY ROADS!!! DO NOT LEAVE
UNIT LOADED FOR LONG PERIODS OF TIME!!!
Scale accuracy with weigh bars is 0.025 %( 1/4
th
of 1%) of the load. Readout display is in
2
or 5
kg increments.
SEE SCALE MANUAL FOR PROPER OPERATION
.
Observe (4) bolts on each load cell stabilizer bracket. They should move freely. Battery or
12 volt power supply must have a minimum of 12 volt-15volt for satisfactory operation of
scale.
SEE SCALE MANUAL FOR PROPER OPERATION.
Battery terminals, connections must be clean and corrosion free and kept tightened. Loose
connection to power or ground will interfere with scale.
Observe J-Box, load cell cables, and power cords for cuts, hanging loose or pulled too tight
at the terminals and for loose connections. Correct these conditions.
CAUTION: DO NOT EXPOSE OPEN WIRES, J-BOX OR SCALE
INSTRUMENTS TO DIRECT FORCE OF WATER.
All entry points are water
resistant, but must not be subjected to direct force of water.
Scale instruments are very dependable, but microprocessors are sensitive to electrical
interference.
(I)
For stationary Bale Wagon operated from commercial power, be sure to confirm
that the power source is stable.
(II)
Check to eliminate the power supply as the source of a scale problem. To do this
connect the scale directly to a separate charged 12 volt vehicle battery. If the
scale problem goes away, the power source is the problem.
(III)
This method may also be used to trace or isolate many other glitches from
unknown sources.
CAUTION: SCALE REPAIRS ARE BEST ACCOMPLISHED BY TRAINED AND
QUALIFIED SCALE REPAIR PERSONNEL.
CAUTION: ELECTRICAL MOTORS, POWER SUPPLIES, AND CONTROL
CABINETS MUST BE REPAIRED BY QUALIFIED SERVICE ELECTRICANS.
