SUMMIT SB-1150SB-1150 Bariatric Wheelchair Scale

Introduction

• The Summit SB-1150 bariatric wheelchair scale is a heavy-duty scale that offers exceptional performance in clinics and hospitals. Patients walk or can be wheeled onto the weighing platform to be
• weighed. The scale is a fully electronic, low profile floor scale that measures 36 in x 36 in (.91 m x .91 m) and has a capacity up to 1000 lb (500 kg). The SB-1150 uses four corner-mounted, alloy steel shear beam load cells with the cells recessed into the frame channels for protection.
• The Summit SB-1150 comes with a large one inch LCD indicator display and 6 AA batteries for use when power is not available. There is an optional 120/220V AC adapter which can be purchased.
  Load cell cables run through the main channels and are held down with replaceable cable ties near each corner to eliminate the possibility of cable damage. One threaded hole, located in the center of the deck, allows for placement of a removable eyebolt for lifting the scale from above with chains. The scale must always be lifted from above with chains through the eybolt to avoid the possibility of foot and load cell damage from forklift tines. Adjustable feet allow for leveling the scale in the event of minor floor irregularities.

Standard installation of the scale consists of the following:

• Site preparation
• Unpacking the scale
• Assembly
• Electrical interface to the indicator
• Load cell connections
• Powering the scale

Site Preparation

Consider the following when choosing a site for the scale:

• Select a site where overweight loads can maneuver easily without crossing the platform
• Avoid areas where damage could occur from side impacts of wheels or forklift tines
• Avoid areas where falling objects could cause shock damage
• Avoid areas where water may damage a scale not meant for a washdown environment
• The scale must be level within 1/4 in of horizontal
• The interface cable between the scale and the indicator must be protected from crushing, cutting and moisture damage

IMPORTANT

• The scale must not be loaded beyond capacity, even momentarily.
• Choose a site where the floor is level to 1/4 in to avoid excessive shimming. The floor may require modification if unable to select an area up to this standard.
• If the chosen site has potential dangers to cable integrity, cable protection is required, such as running the cable in conduit.

Unpacking

Remove all packing material and inspect the contents for damage possibly caused during shipment. Contact Rice Lake Weighing Systems and the shipper immediately if there is damage to the scale. The shipping container should contain the scale, this manual, scale feet, the indicator, and a 10 foot length of load cell cable.
The Summit SB-1150 wheelchair scale has one threaded hole located in the center of the deck to allow for the installation of an eyebolt. An eyebolt hook and chains can be used to lift the scale. It is recommended to use a 1/2 in-20NF eyebolt for lifting the scale.

Assembly
