1.0 Introduction
The Altralite Floor Scale is a fully electronic, low profile load receiver. The Altralite Floor Scale is available in 4' x 4' (1.22 m x
1.22 m) with the capacity of 5K (2267.96 kg). The Altralite Floor Scale uses four corner-mounted, FM-approved load cells, with
the cells recessed into the frame channels for protection. A signal-trim summing board enclosed in a stainless steel, NEMA
Type 4X junction box is included for corner corrections.
All models come pre-trimmed. Corner corrections should not be necessary.
Load cell cables are enclosed in conduit through the main channels, and held down with replaceable cable ties near each
corner, eliminating the possibility of cable damage in portable applications. Also useful for portable applications are threaded
corner holes in the deck for removable eye bolts to allow lifting the scale from above with chains.
The possibility of foot and load cell damage from forklift tines, the scale should always be lifted from above with
chains through the eye bolts.
The adjustable feet are used to allow leveling the scale to make up for minor floor irregularities. For permanent installations, two
of the four feet can be held in place on the floor with optional floor mounting plates to guard against deck movement.
Other available options include custom frames for pit installations, and access ramps for all sizes and models of the Altralite
Floor Scale. Decks designed for use in pits can be ordered with holes drilled in the deck directly above each foot for adjusting
foot height with a screwdriver from above.

2.0 Installation
This section provides information regarding the installation of the Altralite Floor Scale.
2.1 Installation Overview
Standard installation of the Altralite Floor Scale consists of the following steps:
1. Select a site.
2. Check levelness and smoothness of site.
3. Unpack scale.
4. Adjust the four feet on the scale.
5. Install mounting plates to the floor.
6. Connect cable to junction box and indicator.
7. Calibrate the unit.
Pit installations and access ramps are described in Section 2.6 on page 5 and Section 2.7 on page 6.
Consult factory for additional pit and access ramp information at www.ricelake.com.
2.2 Site Preparation
The scale must not be loaded beyond its capacity.
Do not select a site where overweight loads would have to maneuver to avoid crossing the platform.
Avoid areas where the scale might receive damaging side impacts from wheels or forklift tines, or shock
damage from falling objects.
Avoid areas where water may damage a scale not meant for a washdown environment.
The interface cable between the scale and the indicator must be protected against crushing, cutting, or moisture damage.
If the chosen site has potential dangers, some method of protection, such as running the cable in conduit, will be necessary.
In operation, the scale must be level within 1/4''. Either choose a site where the floor is close to this standard to avoid excessive
shimming, or modify the floor at the chosen site to meet this standard.
2.3 Unpacking
Remove all packing material and inspect scale for visible damage caused during shipment.
All Altralite Floor Scale models have threaded holes in the deck to allow installation of eye bolts with shoulders for use when
lifting the scale with chains or using a spreader bar.
Lift the scale only with a properly designed spreader bar as shown in Figure 2-1.
Lifting force must be vertical to avoid bending the eye bolts.
Eye bolts must always be inserted into the top of the scale. Lifting should always occur with the top plate facing
up and the eye bolts securely attached through the nuts welded to the bottom side of the top plate.
Lifting from the bottom of the plate could cause nuts to break loose and the scale to fall.

2.4 Assembly
The following paragraphs present instructions for installing and adjusting the scale feet and mounting plate installation.
2.4.1 Installing and Adjusting Feet
For load cell protection during shipping, the scale feet are shipped detached from the load cells. The feet are secured to the
bottom of the shipping pallet along with the load cell cable, strain relief fitting and product literature.
1. Remove all parts from the envelope.
2. Screw one foot into each load cell and turn until the foot touches either the load cell or the underside of the deck.
3. Unscrew each foot with three complete turns.
4. Place a spirit level on the deck.
Adjust any high corners not in contact with the floor by further unscrewing the feet on those corners until they just
contact the floor surface.
5. When all feet are in contact with the floor, check the deck with the spirit level to be sure the scale is within 1/4'' of level.
2.4.2 Mounting Plate Installation
For permanent applications, the scale should be secured to the floor to prevent sideways movement. Two mounting plates, with
holes that slightly exceed the foot diameter, are available as an option for that purpose.
1. Lift the scale so that the feet are approximately 1'' off the floor.
2. Slide mounting plates under two diagonally opposed feet.
3. Lower the scale back to the floor, and position the plates as shown in Figure 2-2 so that the bolt down holes are
accessible from above.
4. Using the mounting plates as templates, drill pilot holes into the floor for suitable anchor bolts.
5. Bolt the plates to the floor using 1/2'' anchor bolts.
6. Recheck foot adjustment and deck level after this operation.
For installations using access ramps, mounting plates are not necessary as the ramps have built-in mounting plates
to secure the scale feet.

2.5 Junction Box Connections
The indicator terminal strip is used to connect the main cable to the indicator which is shown in Figure 2-3.
Determine the indicator load cell input connections from the device operation manual.
Run a cable from your indicator terminal into the junction box and make the connections. The following table shows the correct
junction box connections using the cable color code.
Installations may vary. Check the load cell color code of the unit.
Figure 2-3. Junction Box Indicator Terminal
2.5.1 Electrical Interface to Indicator
20' of 6-wire cable to connect the scale to the weight indicator is supplied with each scale. The cable must be routed to the
indicator in a manner that will protect the cable from damage. Two methods of cable protection in non-washdown applications
are shown.
When planning cable routing with either of these two methods, leave a loose coil of excess cable under the scale to
facilitate future lifting of the scale for servicing or cleaning.
Figure 2-4. Electrical Interface to Indicator
1. When the interface cable is protected and in its final position, complete connections to the indicator. See indicator
installation manual for wiring information.
If necessary, trim corners as described in Section 3.2 on page 7.
2. Check all strain relief fittings for tightness.
3. Slide the junction box assembly into the cutout and secure it with the two #10 x 3/8'' screws provided.

2.6 Pit Installation
Consult factory for additional pit information at www.ricelake.com.
The Altralite Floor Scale can be installed in a shallow pit using the optional Altralite Floor Scale pit frame.
Optional height-adjustment holes are available. The following site considerations and pit frame drawings are meant only as a
brief overview of the principles involved with mounting the scale in a floor-level pit.
The pit must be installed in a suitable poured-concrete foundation according to standard construction practices.
Figure 2-5. Cover Plate
Figure 2-6. Section Showing Installed Altralite Floor Scale and Pit Frame
Site Considerations
Debris, floor sweepings, or material spills may accumulate in the pit and interfere with scale operation.
Periodically clean the pit.
The Altralite Floor Scale has threaded holes for eye bolts so the scale can be easily lifted from the pit.
Plan the pit location out of main traffic areas to prevent such accidental damaging overloads.
Weight overloads, even momentary such as driving a loaded forklift over a scale corner, will damage load cells.
A 1:24 slope is recommended for the pit, with full grouting under the corner pads as shown in Figure 2-4 on page 4.
Corner pads must be fully grouted.

2.7 Access Ramps
Consult factory for additional access ramp information at www.ricelake.com.
Access ramps for the Altralite Floor Scale are designed to bolt to the floor, with built-in mounting plates that attach to the scale
feet. When used with access ramps, side movement of the scale is automatically eliminated, and no other mounting plates are
necessary. Access ramps can only be attached to the scale on one of the two scale sides that are perpendicular to the
longitudinal axis of the load cells.
Example: The scale shown in Figure 2-6 on page 5 could have an access ramp on the left side as shown, and/or
on the right side. The top and bottom sides, will not accept the ramp mounting plates.

3.0 Calibration
This section provides information regarding calibration of the Altralite Floor Scale.
3.1 Mechanical Adjustments
To accommodate minor floor unevenness, scale feet can be used to adjust scale height up or down a fraction of an inch.
Adjust the feet by hand (lift the scale corner slightly with a pry bar) until all feet are contacting the floor equally. No jam nuts are
supplied for locking the feet, as there is a slight decrease in accuracy when jam nuts are tightened. If the application requires
the feet to be secured, use Teflon tape or Loctite.
When adjusting scale feet, use care to prevent scale foot from bottoming out against the underside of the load
cell. Also, the foot stem may be damaged by bending or stripping threads if extended beyond the maximum
height adjustment.
When height adjustments are complete, recheck level of the deck with a spirit level. The deck must be level within 1/4".
3.2 Corner Correction
The Altralite Floor Scales are delivered with the junction box corner-trimmed. Corner trimming is only necessary after replacing
a load cell. To calibrate the scale, the output from each load cell must be matched by adjusting the signals with potentiometers
at the junction box. This process is known as trimming.
Figure 3-1. Trim Potentiometers
1. Remove the junction box cover and identify correct load cell terminal corresponding to each corner (labeled CELL 1,
CELL 2, and so on). See Figure 4-4 on page 12 for scale deck corner numbering.
The indicator must be connected and calibrated approximately, but it does not need to indicate the exact weight
value. A test weight is required. The recommended test weight for the Altralite Floor Scale is 25% of scale capacity.
2. With no weight on the scale, zero the indicator.
3. Turn all four potentiometers (shaded areas of Figure 3-1) to increase the reading until a clicking sound is heard from
each potentiometer. This ensures the maximum signal from each load cell.
4. With all potentiometers at full signal, place the test weight over one corner and record the indicated weight.
Repeat the process for each of the other three corners. Load cell with the lowest corner reading is used as a
reference point and is not trimmed.

5. Place the test weight over one of the other three corners and use that cell’s potentiometer to adjust the cell output
down to the reference cell output.
Repeat this procedure with the other two high corners.
6. Adjustments are somewhat interactive, and adjusting the three higher outputs may affect the reference cell output,
especially in smaller scale decks.
7. Rezero the indicator and repeat the test until all corners read within ±.1% of the test weight used.
3.3 Calibration Procedure
Refer to the indicator manual to determine correct calibration procedures.
It is recommended that the scale be exercised before calibration to be certain that everything is seated. Load the
scale to near capacity two or three times.
1. With no load on the scale, place the indicator in its calibration mode and perform a zero calibration.
2. Place test weights on the platform equal to 70% – 80% of the scale’s capacity.
If several weights are used, they should be evenly distributed around the platform. Perform a span calibration.
3. Remove the test weights and check the zero reading.
4. Repeat the calibration process if necessary.

4.0 Troubleshooting
This section provides information regarding the troubleshooting of the Altralite Floor Scale.
4.1 Troubleshooting Guide
4.2 Periodic Maintenance
The space between the platform side and pit frame, and the surface beneath the platform must be periodically cleaned to
prevent debris build up. More frequent cleaning of these areas is necessary with scales mounted in pits.
Do not attempt to use scales with load cells that are not hermetically sealed in washdown applications.
Water damage is a common cause of failure in non-hermetically-sealed load cells. Use care with high pressure
steam wash downs for hermetically-sealed load cells. The steam may not damage the load cells, but the
elevated temperatures may cause incorrect readings until the unit cools to room temperature.

5.0 Limited Warranty
Rice Lake Weighing Systems (RLWS) warrants that all RLWS equipment and systems properly installed by a Distributor or
Original Equipment Manufacturer (OEM) will operate per written specifications as confirmed by the Distributor/OEM and
accepted by RLWS. Altralite fabricated platforms and weldments are warranted against defects in materials and workmanship
for five years. Load cells are warranted for two year and all other components are warranted for one year.
RLWS warrants that the equipment sold hereunder will conform to the current written specifications authorized by RLWS.
RLWS warrants the equipment against faulty workmanship and defective materials. If any equipment fails to conform to these
warranties, RLWS will, at its option, repair or replace such goods returned within the warranty period subject to the following
conditions:
• Upon discovery by Buyer of such nonconformity, RLWS will be given prompt written notice with a detailed explanation of
the alleged deficiencies.
• Individual electronic components returned to RLWS for warranty purposes must be packaged to prevent electrostatic
discharge (ESD) damage in shipment. Packaging requirements are listed in a publication, “Protecting Your Components
From Static Damage in Shipment,” available from RLWS Equipment Return Department.
• Examination of such equipment by RLWS confirms that the nonconformity actually exists, and was not caused by
accident, misuse, neglect, alteration, improper installation, improper repair or improper testing; RLWS shall be the sole
judge of all alleged non-conformities.
• Such equipment has not been modified, altered, or changed by any person other than RLWS or its duly authorized repair
agents.
• RLWS will have a reasonable time to repair or replace the defective equipment. Buyer is responsible for shipping
charges both ways.
• In no event will RLWS be responsible for travel time or on-location repairs, including assembly or disassembly of
equipment, nor will RLWS be liable for the cost of any repairs made by others.
These warranties exclude all other warranties, expressed or implied, including without limitation warranties of merchantability or
fitness for a particular purpose. Neither RLWS nor distributor will, in any event, be liable for incidental or consequential
damages.
RLWS and buyer agree that RLWS’ sole and exclusive liability hereunder is limited to repair or replacement of such goods.
In accepting this warranty, the buyer waives any and all other claims to warranty.
Should the seller be other than RLWS, the buyer agrees to look only to the seller for warranty claims.
No terms, conditions, understanding, or agreements purporting to modify the terms of this warranty shall have any legal effect
unless made in writing and signed by a corporate officer of RLWS and the Buyer.
