1.0 Introduction and System Overview

Dual Ramp  Model (RL-350-2)

Single Ramp Model with Wheel Stop (RL-350-1)

The Rice Lake Bariatric 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-350-1) or dual ramp model (RL-350-2). It provides exceptional performance in applications where typical wheelchair scales are not large enough to meet the needs of the patient.

The Rice Lake Bariatric Wheelchair Scale is a fully electronic, l (.86 m x .86 m), and has a capacity up to 1000 lbs (500 kg). The Rice Lake Bariatric Wheelchair uses four corner-mounted, alloy steel shear beam load cells, with the cells recessed into the frame channels for protection. The Rice Lake Bariatric Wheelchair Scale offers two integral handles and wheels for ease of portability.

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

The Rice Lake Bariatric Wheelchair Scale comes equipped with a anti-slip rubber surface on the scale platform and a large 1" LCD indicator display and a 120 VAC or 230 VAC adaptor to use when power is readily available. It is also capable of operating on the internal sealed lead-acid rechargeable battery when no power source is available.

2.0 Scale Setup

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

2.1 Unpacking Your Scale

The Rice Lake Bariatric 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 Immediately after opening the box, visually inspect your scale to ensure all parts are included and undamaged.

Parts contained in the shipping box include:

• This manual

• Parts box which contains the indicator display

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

2.2 Repacking

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

NOTE: Damage caused by improper packaging is not covered by the warranty.

atform that it came in as shown in Figure 2-1.

3. Move the scale into the area where the weighing processs will occur. It’s recommended to place the scale on a hard, level surface for the most accurate weighments. Thin carpeting is fine but not recommended.

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

Figure 2-2. Remove Plastic Wrapping off of Scale

2.4 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.

1. There must be adequate clearance between the sc clockwise two full turns. This will ensure that there is enough clearance between the scale base and the floor.

2. Carefully unwrap the load cell cable located on the underside of the scale. It will run out the underside of

the scale.

Cable should exit the underside of the scale on the wheeled side of scale.

Figure 2-4. 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.

NOTE: By 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.

NOTE: An un-level base will produce innacurate weight readings.

2.5 Cable Connections

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

NOTE: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.

To protect the indicator during transit, the indicator is shipped in a separate box inside the main shipping container. The following sections apply to indicator connections and setup.

3.1 Load Cell Connections

Your scale comes with ten feet of load cell cable which comes from the bottom of the scale (shown in Figure 3-1). The load cell cable must be connected to the

3.2 AC Power Connections

The Rice Lake Bariatric Wheelchair Scale has a 120 VAC adaptor or 230 VAC adaptor to use when power is readily available. The AC power adaptor plugs into the back of the indicator as shown in Figure 3-4.

The AC adaptor, when not in use, plugs into the back housing of the indicator. Figure 3-4 shows that location.

The Rice Lake Bariatric Wheelchair Scale is capable of running if no additional power source is available. Battery life is approximately 75 hours. If the showing on the display, recharge the battery or connect the scale to an AC power source as soon as possible for accurate weighing.

Battery Charging

When the AC adaptor is connected to a power source, the rechargeable battery goes into recharge mode.

NOTE: To maintain battery longevity we recommend you charge it on a regular basis rather than waiting until it is fully discharged.

The LED indicator light on the back of the scale housing will illuminate red during the charging period, and change over to green when the battery becomes fully charged.

3.3 Getting Ready to Weigh a Patient

Once the scale is properly unpacked and set up, and prior to weighing a patient, step on the scale to check the scale that all functions are working correctly. The scale is calibrated from the factory so simply turn on the scale and step on the scale to get a weight reading. Press the
