2.1 ScaleStandard installation of the scale consists of the following:

• Site Preparation• Unpacking the Scale• Assembly• Electrical Interface to the Indicator• Pit Installation• Load Cell Connections• Powering the Scale

2.2 Site PreparationConsider 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'' of horizontal• The interface cable between the scale and the indicator must be protected from crushing, cutting and moisture damage

The scale must not be loaded beyond capacity, even momentarily.Choose a site where the floor is level to 1/4'' 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.

2.3 Unpacking the ScaleRemove 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, pit frame, scale feet, this manual, the indicator, and a 10' length of load cell cable.The Summit SD-1150-WP 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''-20NF eyebolt for lifting the scale.

Communications


4.0 CommunicationsThe following section provides communications instructions for the Summit SD-1150-WP Wheelchair Scale.The indicator 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 4-3 on page 14 shows where the RS-232 connection is located on the indicator.


The RS-232 parameters are 9600 baud (selectable in the programming mode), 8 data bits, 1 stop bit, no parity and no handshaking.There are three methods of communication:

• Pushbutton keypad print• Escape protocol• Maintenance protocol

4.1 Pushbutton Keypad PrintWith a stable, in-range weight, press and hold for at least three seconds, or until the scale emits two quick beeps.

If the scale does not beep after five seconds, release the button as the weight was either in motion, or out of range.

In the weigh mode, the scale sends the 21 character string: xxxxxxxxx<SP>uu<SP>mmmmm<SP><CR><LF>

Where:xxxxxxxxx is the weight with decimal point and " - " sign, if negativeuu is the unit (lb or kg)mmmmm is the mode (gross or net)

Example:-10 Lb net = <SP><SP><SP><SP>-10.0<SP>lb<SP><SP>Net<SP><SP><SP><CR><LF>10 Lb gross = <SP><SP><SP><SP><SP>10.0<SP>lb<SP>Gross<SP><CR><LF>

Example:In BMI mode (displaying the BMI value), the scale sends the following data:GROSS WEIGHT 215.0 LBTARE WEIGHT 0.0 LBNET WEIGHT 215.0 LBPATIENT HEIGHT 5-01.0 FTPATIENT BMI 30.1

4.2 Escape ProtocolThe escape protocol uses the escape (0X1B or ASCII 27) to indicate that a command is following. On the PC side there must be a software listener created by the vendor that will interpret this protocol. This listener must also take care of all the issues regarding data integrity and other information to ensure the data sent and received is valid.Two examples include:

• Scale initiated communication• PC initiated communication

Maintenance and Troubleshooting


5.0 Maintenance and TroubleshootingThe following section provides maintenance and cleaning instructions for the Summit SD-1150-WP Wheelchair Scale.

Do not immerse the scale in cleaning or other liquid solutions. Do not use Isopropyl alcohol or other solutions to clean the indicator display surface.

5.1 MaintenanceBefore using the scale and after periods of non-use, check the scale for proper operation and function. If the scale does not operate correctly, contact a qualified service personnel.Basic maintenance includes:

• Check the overall appearance of the entire scale for any obvious signs of damage• Inspect the condition of the AC adapter cord for cracking, fraying or broken/bent prongs• Using an adapter that has been used elsewhere may cause issues with the scale• Change batteries on a regular interval; Leaving in for long periods of time can cause batteries to leak

5.1.1 CleaningProper care and cleaning is essential to ensure a long life of accurate and effective operation. Before beginning the cleaning process, disconnect the scale from the AC power source.

• Clean all external surfaces with a clean, damp cloth or tissue• Mild soap and water solution may be used• Standing platform may be cleaned with Isopropyl alcohol• Dry with a clean soft cloth

5.2 TroubleshootingRefer to Table 5-1. to diagnose and correct failures prior contacting service personnel for assistance.
