Installation Overview
Prior to installation of the scale it is im ortant to have the ro er location and a lication
for the articular scale being installed.
The ty ical rocedure for the installation of scales covered in this manual will consist of
the following:
• Choosing a site
• Ensuring that the scale installation site is level
• Un acking the scale and any accessories or com onents
• Adjust the scale’s leveling / load feet
• Connection of an o tional indicator
• Calibrating the scale
Installation Site Preparation
In order to ensure that the scale latform will not be loaded over its intended ca acity
take care that the installation site will not allow unintended loads from being laced on
the scale. Make sure that the scale location is not in a location where items heavier than
the scale’s ca acity may accidently be laced on the scale or in the vicinity of falling
objects.
If the scale has not been designed for a washdown a lication, do not allow the scale to
be laced any area where water may exist.
Take care that the cable between the scale and weight indicator is rotected from being
run over, cut, crushed or susce tible to moisture.
The floor or latform where the scale is being located should be within 1/4” of level
across the length and width of the latform.

npacking
Caution: The scale latform is heavy and can be awkward to handle. Exercise extreme
care when lifting the scale latform to avoid ersonal bodily harm or damage to the
equi ment.
Remove the acking material and ins ect the scale for any visible damage occurring
during shi ment.
On Industrial Bench scales, for shi ing ur oses the latter is fli ed u side down
and the base and s ider assembly set inside.
Remove the com onents from the shi ing box. The load cell will be bolted in lace
and the leveling feet threaded into the corner lates of the base. Fli the base over so
that the leveling feet are sitting on a flat level service. The threaded leveling feet are
adjustable. Adjust as needed referring to the leveling bubble on the scale assembly.
Place the latter over the s ider assembly.

Assembling the Scale
Note that the four threaded overload sto s in the corners of the base assembly have
been adjusted to be tight against the underside of the s ider tubes for shi ing.
Prior to use the overload sto s must be adjusted to allow a roximately a to 1/4” ga
(de endent u on ca acity) between the to of the bolt head and bottom of s ider
tubes. To adjust the overload sto s loosen the jam nut against the corner late and
then turn bolt head to ro er distance. Retighten the jam nut to revent the overload
sto s from moving. If the s ider tubes “bottom out” against any overload sto s with a
load equal to or less than the maximum ca acity, readjust the overload sto s.
Place the latter over the s ider assembly after all adjustments have been made.

11
The Weigh-A-Round Portable Scale and the Weigh Buggy will be shi ed fully
Assembled, ty ically on a skid. The overload sto s have been already adjusted tight
against the s ider assembly at the factory for shi ing ur oses. These will need
adjusted to allow a roximately a 1/4” ga (de endent u on ca acity) between the to
of the bolt head and bottom of s ider tubes. To adjust the overload sto s loosen the
jam nut against the corner late and then turn bolt head to ro er distance. Retighten
the jam nut to revent the overload sto s from moving. If the s ider tubes “bottom out”
against any overload sto s with a load equal to or less than the maximum ca acity, re-
adjust the overload sto s.
Place the latter over the s ider assembly after all adjustments have been made.

12
Connecting the Indicator
De ending on the ty e of scale ordered, the cable from the load cell to the weight
indicator will most likely need to be connected. Scales that are ordered re-calibrated
or a ty ical Weigh Buggy scale will have the connection already made.
Weigh Buggies are constructed with two load cells and require a junction box with
summing board which is included with the scale. The cable between the junction box
and indicator will be rewired rior to shi ing from the factory.
The load cell su lied will ty ically be a Tedea with a 10 foot cable. Do not cut the
cable as the load cell is tem erature com ensated for an exact length of 10 feet.
Check the manual su lied with your articular indicator to determine the ro er load
cell cable in ut connections. Refer to the following chart for load cell wire codes:
Wire Color Code Function
Green + Excitation (In ut)
Black - Excitation (In ut)
Blue + Sense
Brown - Sense
Red + Signal (Out ut)
White - Signal (Out ut)
For alternate interchangeable load cell brands check calibration certificate for wiring
s ecifics. If su lied with a junction box, make certain that all of the cord gri fittings
are tightened with a wrench so that the internal rubber sleeve begins to rotrude from
the nut. Pull slightly on the cables to ensure they do not move.
Refer to your articular indicator’s manual for s ecific calibration rocedure. In general
you should lace the indicator into “calibration” mode and erform a zero calibration
with no weight on the scale. Then lace test weights on the scale equal to 70%-80% of
the scale’s total ca acity. If several test weights are being used they should be s aced
evenly around the latform.
Remove all test weights and check the zero reading on the indicator. If necessary,
re eat the above rocedure for calibration and then remove the indicator from its
calibration model.

13
Trouble Shooting
• The indicator does not o erate (no dis lay): - Check power source / plug
- Fuse in indicator has blown
- Connection cable is cut
- Incorrect connection to scale
• The indicator dis lay stays at zero: - Faulty indicator
- Incorrect connection for load cell wires
• Varying weight indication: - Scale platform is not level
- Check for items under platform (binding)
- oad cell or cable water damage
- vibration near scale (remove source)
- Faulty indicator
• Consistently weighing incorrectly: - Scale platform / cover is binding
- Overload stops are set too high
- Indicator not calibrated correctly
- oad cell is damaged

14
Load Cell Replacement
If a load cell should need re laced, verify the art number with the s are arts list in
this manual. Re lacement cells should be of the same ca acity of the cell that is being
re laced.
Lift the scale’s cover latter ex osing the s ider assembly and load cell. Unbolt the
s ider from the load cell, and then the load cell from the base. For Weigh Buggy
ortable ho er scales, use of a jib crane or fork lift will be required to remover the
ho er assembly.
Disconnect the wire leads from the indicator or the summing board in the case of two
load cells in a Weigh Buggy.
Prior to bolting the new load cell in lace, route the cable back through the scale
and reconnect the wire leads to the indicator or the summing board.
Torque the mounting bolts er the following chart:
BOLT DIAMETER TORQUE
1/4”-2 14 FT. LBS.
5/16”-18 29 FT. LBS.
Recalibrate scale er the revious instructions in this manual and er the indicator’s
manual.
