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. Indicates a potentially hazardous situation that, if not avoided, may result in minor or Caution moderate injury.
3.0 3.1 Scale Assembly Unpacking Your Scale Place the unopened box in an open area that has ample room for unpacking the scale. Parts contained in the shipping box include: • The scale • This manual • Small box containing AA batteries (6) and scale feet. 3.2 Repacking If the Digital Wheelchair Scale with seat must be returned for modification, calibration or repair, it must be properly packed with sufficient packing materials. Whenever possible, use the original carton when shipping the scale back.
3.4 Attaching the Feet to the Scale The Rice Lake Digital Wheelchair Scale comes with four feet that must be attached to the scale base for proper operation. The four feet are located in the parts box in the original shipping box. Prior to laying the scale base on the floor, use the following steps to attach the feet to the scale. 1. Screw the four round feet clockwise into the scale base as shown in Figure 3-1. Figure 3-1. Screw Feet Into the Scale Platform 2.
3.5 Handle Setup 1. Loosen the handles and unfold and set upright (handles shown in Figure 3-3). 2. Tighten the two hinges on the wheelchair scale by rotating the two handles. This will secure the handrail mounted indicator. Figure 3-3. Secure the Handrail by Tightening the Durable Hinges 3. The wheelchair scale with seat comes fully assembled (as shown in Figure 3-4). Figure 3-4.
4. To open the chair, gently pull up on the seat portion of the scale and pull down on the legs so that they straighten out and rest on the scale platform. Figure 3-5. Secure Bracket 5. Ensure the retaining bracket is secure (as shown in Figure 3-5). Warning The retaining bracket must click into place. If it doesn’t click it may not be secure and any weight applied to it may cause it to collapse. 6. The chair is ready to weigh patients while open and on the platform. Figure 3-6.
3.6 Inserting Batteries The six AA batteries that come with the scale offer an average of 25 hours of continuous use. To install the batteries: 1. Open the battery chamber cover by loosening the thumbscrew. 2. Insert batteries into the battery chamber as shown in Figure 3-7. Figure 3-7. Battery Chamber 3. Close the battery chamber. If an external power supply or USB power supply is connected, the battery flag on the display is turned off.
4.0 Scale Operation The Rice Lake Digital Wheelchair Scale with seat display has various front panel keys as shown in Figure 4-1. Figure 4-1. Front Panel Display Keys Key Descriptions Table 4-1 describes each of the key functions. Key Name Function On/Off Switches the scale on or off.

7.0 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 7-5 on page 21 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.
7.2 Communication Protocols The Rice Lake Digital Wheelchair Scale with seat has two communication protocols, escape and maintenance protocol. 7.2.1 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 7-1 and 7-2 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 7-1.

Sample of Escape Protocol When the user wants to diagnose the problems on the scale, it looks like the Figure 7-3 and 7-4.
7.2.2 Maintenance Protocol Table 7-4 lists the maintenance protocol commands. Command Definition R Reboot V Firmware ID + development version W Current weight A Current AD Z Zero the scale F Show flash values (used for the first flash process) L USB On/Off (not available on USB communication Table 7-4. Maintenance Protocol Commands 7.3 USB Connection The Rice Lake Wheelchair Scale has the capability of connecting to a PC using a USB connection and a USB cable (not included).
1. The graphic below shows the window that pops up when the USB cable is connected to the indicator and the scale is turned on. Follow the screen prompts to navigate through the screens below. 2. Select No, not this time and then select Next. 3. Select Install the software automatically, then select Next.
4. The following screen appears while the driver is installing on to your system. 5. The following screen appears when installation is complete. Click on Finish. 6. If you want to verify the installation, you can view the driver by looking at the device manager of your system.
7. To print a ticket using the USB driver, open the software driver (shown above) and the port assigned to that driver is shown. 8. Ensure that the USB cable is properly connected and unit is on. 9. Another terminal type program (such as Hyperterminal) needs to be opened and connected through the USB driver to the indicator to be able to see the information being sent to the PC. A port needs to be established so select the port that is assigned to Parpar and print the ticket.
8.0 Troubleshooting and Testing Refer to the following to check and correct any failure before contacting service personnel. Symptom Scale does not turn on Questionable weight or the scale does not zero Possible Cause Corrective Action Dead battery Connect the scale to a power source. Faulty electrical outlet Use a different electrical outlet. Bad power supply Replace adapter. External object is interfering with the scale. Remove the interfering object from the scale.
