Introduction 1
1.0 Introduction
The Summit 3000 floor scale provides exceptional performance and is an economical solution in light industrial
applications. The
Summit 3000 floor scale is a fully electronic, low profile floor scale that comes in sizes from 36 in
x 36 in (.91 m x .91 m) to 60 in x 60 in (1.52 m x 1.52 m), and capacities from 2000 to 10,000 lb (1000 to 5000 kg).
All models use four corner-mounted, NTEP-certified, alloy steel shear beam load cells, with the cells recessed into
the frame channels for protection. All models are shipped pre-trimmed, so corner corrections are not needed on
arrival. However, the signal trim summing board is enclosed in a durable ABS enclosure that has a convenient
top-access for future corner corrections.
Other available options include custom frames for pit installations and access ramps for all sizes.

2.0 Installation
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.
Figure 2-1. Proper Lifting Technique
Important
WARNING
Large Platform
(Larger then 5 ’ x 5 ’ , and /or more than 10,000 lb capacity)
Use two 3/4
” eye bolts, insert into threaded holes in
opposite corners of top plate for lifting.
Small Platform
(5
’ x 5 ’ or smaller and/or 10,000 lb or less capacity)
Use one 1/2
” eye bolt, insert into threaded hole in
center of top plate for lifting.

2.4 Assembly
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.

2.5 Electrical Interface to Indicator
To connect the scale to the weight indicator, twenty feet of 6-wire cable is supplied with each scale. The junction
box is easily accessible through a top access plate located on the top of the Summit 3000. Use the following steps
to wire up the junction box.
1. Remove the four screws using an Allen wrench.
2. Lift the junction box assembly out of the scale deck.
3. Open and remove the top of junction box.
Figure 2-4. Junction Box Opened
4. Push the cable end into the junction box through a cord grip.
5. Connect the wires to the indicator terminal (Figure 2-4) as shown in Table 2-1.
6. Pull out excess and tighten the cord grip to hold the cable snugly.

7. Route the cable so that it is protected from damage. Leave a loose coil of excess cable under the scale to
allow for servicing and cleaning.
8. Connect the cable to the indicator. See the indicator installation manual for wiring information.
9. If necessary, trim corners as described in Section 3.2 on page 9.
10. Check all strain relief fittings for tightness.
11. Put the cover back onto the junction box assembly and place the junction box back into the floor scale cutout.
12. Secure the Summit 3000 floor plate.
