1.1. INTRODUCTION
The Aegis Xtreme-duty Scale is an extremely rugged floor scale, designed for
high capacities and a wide variation of dimensional sizes. This is because of the
additional I-beam supports under the platform that run both along the scale’s “X” and
“Y” axis.
It has an extremely low-profile design. The scale’s floor height is 8 or 9 inches,
depending on the capacity.
The Aegis Xtreme-duty Scale is designed for applications with high load
concentrations.

wired. The standard scale installation consists of the following steps.
• Unpack the Scale, and any components.
• Selecting the best Platform Site Location.
• Connect lifting straps or chains to the lifting lugs on the sides of the platform,
then move it to the designated site using a crane.
• Install the Ramps (if applicable).
• Level the Platform.
• Install and wire the Instrument to the Platform.
• Adjust and Calibrate the Scale according to the appropriate Indicator Service
Manual.

Section 3: Scale Installation
3.2.1. Unpacking
Follow these guidelines when unpacking all equipment.
Check in all components and accessories according to the customer's order. Remove all components from their packing material, checking against the invoice
that they are accounted for and not damag e d .
Advise the shipper immediately, if damage has occurred.
Keep the shipping container and packing material for future use.
Order any parts necessary to replace those which have been damaged.
Check the packing list.
The CUSTOMER is the receiving party if the equipment was shipped to
the Customer’s address.
FAIRBANKSis the receiving party if the equipment was shipped to the
Fairbanks Service Center.
Collect all necessary installation manuals for the
equipment and accessor i es.
Open the equipment and perform an inspection, m aking
certain that all hardware, electrical connections and printed
circuit assemblies are secure.
Do not reinstall the cover if the final installation is to be
performed after the pre-installation checkout.
Do not load the platform if there is any evidence of damage
to the platform or supporting structure.
NOTE: It is the owner's responsibilit y to document, notify, and follow-up
regarding shipping damage with the carrier.

Section 3: Scale Installation
3.2.2. Positioning the Scale
Position the Scale with these points in mind:
Use the proper lifting equipment to position and place the scale. The scale is to be placed on a flat, solid, level surface, one that fully supports the
weight of the platform plus a full capacity load.
The smooth surface must be within 1/8”, and on a level plane, within ¼” across
both the length and width of the platform.
The four corners of the Platform must rest solidly on the surface, and not rock.
Irregular bumps and foreign material under the Platform can cause an “out-oflevel” condition, which will affect the weight accuracy.
Platform vibrations ma y also affect the weighing accuracy. Wherever possible,
locate the platform as far away from heavy, low frequency vibrations as much as
possible.
Do not load the platform if there is any evidence of damage to the platform or
supporting structure.
Ease of access is very important. Allow plenty of room for maneuvering a fork lift. Reading the Indicator is also important to workers, so place it in a very visib le
position.
When installing the Scale and Indicator in an outdoor location, set it up so the
snow, ice accumulation, rain and other conditions do not affect the platform
operations.

3.2.3. Positioning Steps
1. Position the Scale into its final location.
2. Place the hooks of the straps or chains into the specific lifting points of the Scale.

on each side of it, and also into each hole of the ramp.
3. Place the platform in the desired location.
─ The platform should be made stable and level.

4.2. SCALE PLATFORM TROUBLESHOOTING
Except for severe structural damages, most
Platform Assembly problems can be traced to
the following causes.
• Material under or around the Platform.
• Broken Load Cell receiver cups..
• Faulty Load Cells.
4.2.1. Scale Platform Testing
1. Inspect the Interface Cable from the Platform to the Instrument f or visible breaks
or cracks.
2. ZERO the Instrument Display.
3. Apply a test load of
25% of the Load Cell capacity to one corner.
─ The Instrument should display a weight reading within 0.1% of the applied
weight, or One Instrument Division, whichever is greater.
