The Summit® SD-1150-WP Dialysis Scale is a heavy-duty scale that offers exceptional performance in dialysis
centers and hospitals. The patient simply walks, or is wheeled onto the weighing platform and is weighed.
The Summit SD-1150-WP Dialysis 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 SD-1150-WP uses four corner-mounted, alloy
steel shear beam load cells, with the cells recessed into the frame channels for protection. The SD-1150-WP is
designed to be mounted in a pit flush with the floor.
Load cell cables are run through the main channels, and held down with replaceable cable ties near each corner,
eliminating the possibility of cable damage. One threaded hole, located in the center of the deck, is another useful
feature which allows for placement of a removable eyebolt to lift the scale from above with chains. Because of
the possibility of foot and load cell damage from forklift tines, the scale should always be lifted from above with
chains through the eyebolt which is illustrated in
The adjustable feet are used to allow leveling the scale to make up for minor floor irregularities.
The Summit SD-1150-WP comes equipped with a large 1" LCD indicator display and 6 AA batteries for use
when power is not readily available. There is an optional 120/230V AC adapter which can be purchased.

3.0Scale Installation
The following sections describe the correct installation procedures when installing the Summit SD-1150-WP
Dialysis Scale.
3.1Overview
Standard installation of the Summit SD-1150-WP Dialysis 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.
3.2Site Preparation
The scale must not be loaded beyond its capacity, even momentarily. Avoid areas where the scale might receive
damaging side impacts from wheels, or shock damage from falling objects. Avoid areas where water may
damage a scale not meant for a washdown environment.
The interface cable between the scale and the indicator must be protected against crushing, cutting, or moisture
damage. If the chosen site has such potential dangers, some method of protection, such as running the cable in
conduit, is necessary.
In operation, the scale must be level within 1/4". Either choose a site where the floor is close to this standard to
avoid excessive shimming, or modify the floor at the chosen site to meet this standard.
3.3Unpacking
Remove all packing material and visually inspect the scale and pit frame for visible damage caused during
shipment. The shipping container should contain the scale, pit frame, scale feet, this manual, the indicator, and a
10-ft length of load cell cable.
The Summit SD-1150-WP Dialysis Scale has one threaded eyebolt hole located in the center of the deck to allow
installation of an eyebolt hook for use when lifting the scale with chains. It’s recommended to use a 1/2 in-20NF
eyebolt to lift the scale.
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. When all feet are in contact with the floor, check the
deck with the spirit level to be sure the scale is within 1/4 inch of level.
3.5Electrical Interface to Indicator
Ten feet of 4-wire cable to connect the scale to the weight indicator is supplied with each scale. The junction box
is easily accessible through an access plate located on the side of the Summit SD-1150-WP. Use the following
steps to wire up the junction box.
1. Remove the two #10 x 3/8" screws.
2. Slide the junction box assembly out of the deck.
3. Open and remove the top of junction box.
4. Push the cable end into the junction box through a cord grip.
5. Connect the wires to the indicator terminal (Figure 3-2) as shown in Tab le 3-1.
6. Pull out excess and tighten the cord grip to hold the cable snugly.

9. If necessary, trim corners as described in Section 4.2 on page 7.
10. Check all strain relief fittings for tightness.
11. Put the cover back onto the junction box assembly and slide the junction box back into the floor scale
cutout.
12. Secure the Summit SD-1150-WP side plate.
3.6Pit Installation
The Summit SD-1150-WP Dialysis Scale can be installed in a shallow pit using the optional Summit
SD-1150-WP pit frame. Optional height-adjustment holes are available. The following site considerations and pit
frame drawings are meant only as a brief overview of the principles involved with mounting the scale in a
floor-level pit. The pit must be installed in a suitable poured-concrete foundation according to standard
construction practices.
Figure 3-4. Pit Frame Diagram
Site Considerations
Debris, floor sweepings, or material spills may accumulate in the pit and interfere with scale operation. You
should periodically clean the pit. The Summit SD-1150-WP has a threaded hole centrally located for eyebolts so
the scale can be easily lifted from the pit.
A 1:24 slope is recommended for the pit, with full grouting under the corner pads as shown in Figure 3-5.

4.0Adjustments and Calibration
Potentiometers
The following sections describe adjustments that need to be made to the Summit SD-1150-WP Dialysis Scale.
4.1Mechanical 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. No jam nuts are supplied for locking the feet, as there is a slight decrease in accuracy when jam
nuts are tightened. However, if you feel that your application requires you to secure the feet, we suggest using
®
Teflon
When adjusting scale feet, use care to prevent the scale foot from bottoming out against the underside of the load
cell. Also, the foot stem can be damaged by bending or stripping threads if extended beyond the maximum height
adjustment.
When height adjustments are complete, recheck level of the deck with a spirit level. The deck must be level
within 1/4".
4.2Corner Correction/Trimming
The assembled Summit SD-1150-WP scale is delivered with the junction box corner-trimmed. Corner trimming
is only necessary after replacing a load cell.
To calibrate the scale, the output from each load cell must be matched by adjusting the signals with
potentiometers at the junction box—a process known as trimming.
Remove the junction box cover and identify the correct load cell terminal corresponding to each corner (labeled
CELL 1, CELL 2, and so on). See
The indicator must be connected and calibrated approximately, but it need not indicate the exact weight value. A
test weight is required. The recommended test weight for the SD-1150-WP is 25% of scale capacity.
With no weight on the scale, zero the indicator. Then turn all four potentiometers (Figure 4-1) clockwise to
increase the reading until a clicking sound is heard from each potentiometer. This ensures the maximum signal
from each load cell.

SD-1150-WP Installation & Operation Manual - Adjustments and Calibration7
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.
Adjustments are somewhat interactive, and adjusting the three higher outputs may affect the reference cell
output, especially in smaller scale decks. Rezero the indicator and repeat the test until all corners read within
±.1% of the test weight used.
4.3Calibration Procedure
It is recommended that the scale be “exercised” before calibration to be certain that everything is seated. Load
the scale to near capacity two or three times.
Then, with no load on the scale, place the indicator in its calibration mode and perform a zero calibration. Now
place test weights on the platform equal to 70% - 80% of the scale’s capacity. If several weights are used, they
should be evenly distributed around the platform. Perform a span calibration.
Remove the test weights and check the zero reading. Repeat the calibration process if necessary.

9.0RS-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.
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:

•If displaying weight and not BMI, the scale will send out the following 21 character string:
xxxxxxxxx is the weight with decimal point and " - " sign, if negative uu is the unit (lb or kg).
mmmmm is the mode (gross or net)
In case of under weight or over weight, the word Under or Over will be sent correspondingly.
20SD-1150-WP Installation & Operation Manual
9.2Communication Protocols
The Rice Lake Digital Wheelchair Scale has two communication protocols, escape and maintenance protocol.
9.2.1Escape 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. to make sure that the data that was sent
and received is valid.
Two examples include:
•Scale initiated communication
•PC initiated communication

11.0Maintenance
The following section provides instructions for maintaining and cleaning the Rice Lake line of scales.
Maintenance operations other than those described in this section should be performed by qualified service
personnel.
11.1Basic Maintenance
Before the first use of the scale and after periods of non-use, check the scale for proper operation and function. If
the scale does not operate correctly, contact qualified service personnel.
Go through the following steps for basic maintenance.
1. Check the overall appearance of the entire scale for any obvious signs of damage.
2. Inspect the condition of the AC adapter for cord cracking or fraying or for broken or bent prongs.
11.2Cleaning
Proper 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.

Replacement load cells can be ordered from Rice Lake Weighing Systems. To replace a load cell, lift the scale
with a chain and remove foot, then remove the defective load cell. Disconnect load cell cable from the junction
box and cut cable ties. When the cable is freed, pull cable out of the scale frame channels.
Figure 11-1. Load Cell Assembly
Follow the directions given below to install new load cells.
Lay out the four load cells near the corners where they are to be installed. Thread the cable from each load cell
through the conduit tubing in the frame and into the junction box according to the wiring diagram in
Note that in Figure 11-2 both the scale and the junction box are viewed from the bottom. To verify correct load
cell/junction box terminal matching, see the numbers on the terminals inside the junction box and the corner
numbering diagram in
Figure 11-4 28.
Figure 9-3.
Check that the threaded holes for the load cell screws are free of debris. Use compressed air to blow out holes if

necessary. Position load cells with alignment arrows pointed up toward the deck and loosely install the hex head
cap screws provided, as shown in
Figure 11-1. If the base is used with a pit frame or access ramp, position the
load cell to maintain the dimension shown in Figure 11-3. With the torque wrench, tighten all bolts to 75 ft-lb.
Route the load cell cables near each corner so that the
cable is free from possible contact with each foot.
Hold the cable in position with the supplied
adhesive-backed cable ties.
Do not cut load cell cables. Coil extra cable before it
enters the junction box, tie with cable ties, and insert
the coils into the channel near the junction box.
After coiling excess cable, pass each individual end of
load cell cable through its grommet in the junction
box cover (or through cable fittings in the NEMA 4X
junction box).
Corner correction trimming and calibration is
necessary after load cell replacement. Follow
instructions in
Section 4.2 on page 7.
11.3.1Load Cell Wiring to Junction Box
The four load cells are each wired to their respective
terminals in the junction box according to the corner
numbering system shown in
coloring code in Table 11-1.
Pull excess cable out of the junction box enclosure
and tighten the cable grips with a wrench. To be
watertight, the cable grips must be tightened to the
point where the rubber sleeving begins to protrude out
of the hub. Finally, pull on each of the four cables to
make sure that they do not slip.
