1.0 Introduction

The Rice Lake Wheelchair Scale is a heavy-duty scale that easily accommodates wheelchairs with its large
platform size and easy-access ramp in either a single ramp (RL-350-5) or dual ramp model (RL-350-6). It
provides exceptional performance in applications where typical wheelchair scales are not large enough to meet
the needs of the patient.

The Rice Lake Wheelchair Scale is a fully e
.86 m), and has a capacity up to 1000 lb (450 kg). The Rice Lake Wheelchair uses four corner-mounted, alloy
steel shear beam load cells, with the cells recessed into the frame channels for protection. The Rice Lake
Wheelchair Scale offers two integrated handles and wheels for ease of portability.

Load cell cables are run through the main channels, and held down with
eliminating the possibility of cable damage in portable applications.

The adjustable feet are used to allow leveling the scale to make up
feet sit inside the foot keeper plates located on the front of the ramp.

The Rice Lake Wheelchair Scale comes equipped with a anti-slip rubber
1" LCD indicator display. The indicator comes with six AA batteries and has an optional AC adaptor available.

Note

The following sections describe the correct installation procedures when installing the Rice Lake Wheelchair
Scale.

3.1 Unpacking Your Scale

The Rice Lake Wheelchair Scale comes shipped in a wooden two piece box. Place the unopened box in an open
area that has ample room for unpacking the scale.

Recommended tools needed to set up your sc

• Scissors or box cutters

• Small Phillips screwdriver

Using scissors or a box cutter, cut the

• Parts box which contains the indicator display

strapping bands that secure the box together. Lift off the top cover.

3.2 Repacking

If the Rice Lake Wheelchair Scale must be returned for modification, calibration or repair, it must be properly
packed with sufficient packing materials. Whenever possible, use the original box when shipping the wheelchair
scale back.

Damage caused by improper packaging is

4. Stand the scale on its side so that the plastic packaging material can be removed.

3.4 Scale Feet Adjustment

The scale feet are shipped attached to the scale. Adjustments need to be made in order for the scale to sit properly
on the floor.

the scale.

Figure 3-4. Unwrap the Cable from the Underside of the Scale

3. Gently set the scale base down to the floor. There should be minimal clearance between the scale base
and the floor without having the scale base actually touching the floor.

Not having clearance around the scale base will create inaccurate weighments.

4. It’s also important to make sure that the scale is completely level. Gently press down on all corners of the
scale base to ensure that there are no high spots or rocking of the scale base.

An un-level base will produce inaccurate weight readings.

3.5 Cable Connections

Ten feet of 4-wire cable to connect the scale to the weight indicator is supplied with each scale.

The cable is pre-installed from the factory.

The cable must be routed to the indicator in a manner that will protect the cable from damage.
Cabling should exit the underside of the scale on the portable wheel side of the scale and not the ramp side(s).
When planning cable routing, leave a loose coil of excess cable under the scale to facilitate future lifting of the
scale for servicing or cleaning.

USB Connection

RS-232 Connection

The scale comes with an RS-232 port which enables weight data to be transmitted to other equipment, such as a
computer or printer. The RS-232 cable with DB-9 connector (PN 100719) is available from Rice Lake Weighing
Systems. Figure 6-1 shows the RS-232 connection location.

The RS-232 parameters are 9600 baud (selec
and no handshaking.

There are three methods of communication:

• Pushbutton keypad print

• Standard remote protocol

• Escape protocol

Rice Lake Wheelchair Scale 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. All systems and components are warranted against defects in
materials and workmanship for two years.

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’S 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.
