1.0 Introduction and System Overview The Summit® SB-1150 Bariatric Wheelchair Scale is a heavy-duty scale that offers exceptional performance in hospitals. The patient simply walks, or is wheeled onto the weighing platform and is weighed. The Summit SB-1150 Bariatric Wheelchair 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).
2.0 Safety There are certain precautions that should be taken to prevent personal injury to the user and damage to your scale. 2.1 Safety Signals Safety Signal Definitions: Indicates a potentially hazardous situation that, if not avoided, could result in death or Warning serious injury. Caution Indicates a potentially hazardous situation that, if not avoided, may result in minor or moderate injury.
3.0 Scale Installation The following sections describe the correct installation procedures when installing the Summit SB-1150 Bariatric Wheelchair Scale. 3.1 Overview Standard installation of the Summit SB-1150 Bariatric Wheelchair Scale consists of the following steps: 1. Select a site. 2. Unpack the scale and pit frame. 3. Install the pit frame. 4. Lower the scale into pit frame. 5. Adjust the four leveling feet on the scale. 6. Connect cable to the indicator. 7. Calibrate the scale. 3.
3.4 Assembly For load cell protection during shipping, the scale feet are shipped separately from the floor scale. Screw one foot into each load cell and turn all the way in until the foot touches either the load cell or the underside of the deck. Then unscrew each foot three complete turns. 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.
7. The cable must be routed to the indicator in a manner that will protect the cable from damage. This method of cable protection in non-washdown applications are shown in Figure 3-3. 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. SCALE FLOOR LOAD CELL CABLE Figure 3-3. Load Cell Protection 8. When the interface cable is protected and in its final position, complete connections to the indicator.
4.0 Adjustments and Calibration The following sections describe adjustments that need to be made to the Summit SB-1150 Bariatric Wheelchair Scale. 4.1 Mechanical Adjustments To accommodate minor floor unevenness, the 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.
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. The load cell with the lowest corner reading is used as a reference point and will not be trimmed. Next, 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.
5.0 5.1 Indicator Installation Indicator Installation The Summit SB-1150 Bariatric Wheelchair Scale has several connections on the back of the indicator. Connection points include: • AC power connection • RS-232 port connection • Scale connection port • Adapter storage connection AC Power Connection The Summit SB-1150 Scale has an optional 120 VAC adapter or 230 VAC adapter to use when power is readily available.

9.0 RS-232 Communication The scale comes with an RS-232 port that 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 5-1 on page 8 shows where the RS-232 connection is. The RS-232 parameters are 9600 baud (selectable in the programming mode), 8 data bits, 1 stop bit, no parity and no handshaking.
9.2 Communication Protocols The SB-1150 Bariatric Wheelchair Scale has two communication protocols, escape and maintenance protocol. 9.2.1 Escape Protocol An escape protocol is where the escape (0X1B or ASCII 27) is used to indicate that there is a command following. On the PC side there must be a listener created by the vendor that will interpret this protocol. This listener must also take care of all the issues regarding data integrity, etc.
Samples of Escape Protocol Figure 9-1 and 9-2 show what the diagrams will look like on the PC as the scale measures weight and sends over this communications line: &4$ 3 &4$ & 3#!,% 0# 3FBEJOH SFRVFTU &01 Figure 9-1.
