The following sections describe the correct installation procedures for the Summit 3000 floor scale.

2.1 Overview

Standard installation of the Summit 3000 floor scale consists of the following steps:

1. Select a site.

2. Check levelness and smoothness of site.

3. Unpack the floor scale.

4. Adjust the four feet on the scale.

5. Install mounting plates to the floor (optional).

6. Connect cable to the system.

7. Calibrate the system.

Access ramps and pit installations are described in Section 2.6 and Section 2.7.

2.2 Site Preparation

Do not load the scale beyond its capacity, even momentarily. Avoid areas where the scale might receive
damaging side impacts from wheels or forklift tines, or shock damage from falling objects. Avoid areas where
water may damage a scale which is 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 inch (6.35 mm). Either choose a site where the floor is close to
this standard or modify the floor at the chosen site to meet this standard, to avoid excessive shimming.

2.3 Unpacking

Remove all packing material and visually inspect the floor scale for visible damage caused during shipment. The
shipping container should contain the floor scale, this manual and a 20 ft length of load cell cable.

All Summit 3000 models have 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.

Lift the scale only with a properly designed spreader bar as shown in Figure 2-1.
Lifting force must be vertical to avoid bending the eye bolt.

Eye bolts must always be inserted into the top of the scale. Lifting should always
occur with the top plate facing up and the eye bolts securely attached through the
nuts welded to the bottom side of the top plate. Lifting from the bottom of the plate
could cause nuts to break loose and the scale to fall.

It’s recommended to use a 1/2 inch-13NC eyebolt inch 2000 to 10,000 lb capacity scales.

The following paragraphs give instructions for adjusting the scale feet and anchor plate.

2.4.1 Adjust feet

The scale feet are secured with a jam nut (located next to each load cell) for load cell protection during shipping.

Figure 2-2. Jam Nut Location on Scale Foot

Jam nut must be loosened prior to adjusting scale feet.

Screw one foot into each load cell and turn until each 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 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.

2.4.2 Anchor Plate Installation

For permanent applications, the anchor plate should be secured to the floor to prevent sideways movement of the
scale. Two mild steel floor anchor plates, with holes that slightly exceed the foot diameter, are available as an
option for that purpose.

Lift the scale so that the feet are approximately one inch off the floor. Slide mounting plates under two diagonally
opposed feet. Lower the scale back to the floor and position the plates so that the boltdown holes are accessible
from above, as shown in Figure 2-3 .

Using the mounting plates as templates, drill pilot holes into the floor for suitable anchor bolts. Bolt the plates to
the floor using 1/2 inch anchor bolts. Recheck foot adjustment and deck level after this operation.

For installations using access ramps, mounting plates are not necessary as the ramps have
built-in mounting plates to secure the scale feet.

Important

Note

Debris, floor sweepings, or material spills may accumulate in the pit and interfere with scale operation. The pit
should periodically be cleaned. All sizes of the Summit 3000 have a threaded hole centrally located for eyebolts
so the scale can be easily lifted from the pit.

Plan the pit location out of main traffic areas to prevent such accidental damaging overloads. Weight overloads,
even momentary ones such as driving a loaded forklift over a scale corner, will damage load cells.

A 1:24 slope is recommended for the pit, with full grouting under the corner pads as shown in Figure 2-6.

Figure 2-6. Section Showing Installed Summit 3000 and Pit Frame

2.7 Access Ramps

Access ramps for Summit 3000 floor scales are designed to bolt to the floor, with built-in mounting plates that
attach to the scale feet. When used with access ramps, side movement of the scale is automatically eliminated,
and no other mounting plates are necessary.

Access ramps can only be oriented on the two scale sides that are perpendicular to the longitudinal axis of the
load cells. For example, the scale shown in Figure 2-7 could have an access ramp on the left side as shown,
and/or on the right side. The top and bottom sides, however, will not accept the standard ramp mounting plates.

Align ramp with the longitudinal axis of the load cells.

Optional custom ramps are available.

The following sections describe adjustments that need to be made to the Summit 3000 floor scale.

3.1 Mechanical Adjustments

To accommodate minor floor unevenness, the scale feet can be used to adjust scale height up or down. Adjust the
feet by hand (lift the scale corner slightly with a pry bar) until all feet are contacting the floor equally. Jam nuts
are supplied for locking the feet, as there is a slight decrease in accuracy when jam nuts are tightened. However,

if the application requires securing the feet, it’s suggested to use 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 inch (6.4 mm).

3.2 Corner Correction

All assembled Summit 3000 scales are 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.

1. Remove the junction box cover and identify the correct load cell terminal corresponding to each corner
(labeled CELL 1, CELL 2, CELL 3 and CELL 4). See Figure 4-3 on page 13 for scale deck corner
numbering.

The indicator must be connected and calibrated, but it does not need to indicate the exact weight value. A
test weight is required. The recommended test weight for all Summit 3000 models is 25% of scale
capacity: for example, 500 lb for 2000 lb models, 2500 lb for 10,000 lb models.

Corner Numbering

Adjustments and Calibration 9

2. With no weight on the scale, zero the indicator.

3. Turn all four potentiometers (Figure 3-1) clockwise to increase the reading until a clicking sound is
heard from each potentiometer. This ensures the maximum signal from each load cell.

4. With all potentiometers at full signal, place the test weight over one corner and record the indicated
weight.

5. Repeat this 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.

6. Place the test weight over one of the other three corners and use that cell’s potentiometer to adjust the
cell output down to match the reference cell output.

7. 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
±0.1% of the test weight used.

3.3 Calibration Procedure

Refer to the indicator manual to determine correct calibration procedures.

It is recommended that the scale be exercised before calibration to be certain that everything is seated.

1. Load the scale to near capacity two or three times.

2. With no load on the scale, place the indicator in its calibration mode and perform a zero calibration.

3. Place test weights on the platform equal to 70% - 100% of the scale’s capacity. If several weights are
used, they should be evenly distributed around the platform.

4. Perform a span calibration.

5. Remove the test weights and check the zero reading.

6. Repeat the calibration process if necessary.

Table 4-1. Troubleshooting Table

4.2 Periodic Maintenance

The space between the platform side, the pit frame and the surface beneath the platform must be periodically cleaned
to prevent debris build up. More frequent cleaning of these areas is necessary with scales mounted in pits.

Do not use scales with load cells that are not hermetically sealed in washdown applications. Water damage is a
common cause of failure in non-hermetically-sealed load cells. Use care with high pressure steam washdowns
for hermetically-sealed load cells. The steam may not damage the load cells, however the elevated temperatures
may cause incorrect readings until the unit cools to room temperature.

Service Information 11

4.3 Load Cell Replacement

Replacement load cells can be ordered from Rice Lake Weighing Systems.

Lift the scale with a chain, spreader bar and the provided eyebolt. Remove the foot and 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 4-1. Load Cell Assembly

Use the following directions to install new load cells.

1. Lay out the load cell near the corner where it is to be installed.

2. Thread the cable from the load cell through the frame and into the junction box. Use the terminal
numbers inside the junction box to match the cable.

3. Check that the threaded holes for the load cell screws are free of debris. Use compressed air to blow out
holes if necessary.

4. Position load cells with alignment arrows pointed up toward the deck.

5. Loosely install the hex head cap screws provided, as shown in Figure 4-1. If the base is used with a pit
frame or access ramp, position the load cell to maintain the dimension shown in Figure 4-2.

6. With the torque wrench, tighten all bolts to 75 ft-lbs.

2000 to 10,000 models: 1.625"

Figure 4-2. Foot Pad - Side View

7. 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.

8. 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.

9. 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 instruction in
Section 3.2 and 3.3.
