WARNING
DANGER
The RoughDeck® Floor Scales are fully electronic, low profile load receivers. The RoughDeck scales are available
in sizes from 30 in x 30 in (.76 m x .76 m) to 96 in x 120 in (2.44 m x 3.05 m), and capacities from 2K- to 30K-lb (1000–15000 kg).
All models use four corner-mounted, FM-approved load cells, wi protection. Also included is a signal-trim summing board enclosed in a stainless steel, NEMA 4X junction box for any necessary corner corrections. All models come pre-trimmed; corner corrections should not be necessary.
Load cell cables are enclosed in conduit through the main channe each corner, eliminating the possibility of cable damage in portable applications. Also useful for portable applications are threaded corner holes in the deck for removable eye bolts to allow lifting 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 eye bolts.
The adjustable feet are used to allow leveling the scale to make up installations, two of the four feet can be held in place on the floor with optional floor mounting plates to guard against deck movement.
Other available options include custom frames for pit
installations, and access ramps for all sizes and models of the
RoughDeck. Decks designed for use in pits can be ordered
for adjusting foot height with a screwdriver from above. See Section 4.4 on page 12 for replacement part and optional equipment part numbers.

2.1 Installation Overview

Standard installation of the RoughDeck floor scale consists of the following steps:
1. Select a site
2. Check levelness and smoothness of site
3. Unpack scale
4. Adjust the four feet on the scale
5. Install mounting plates to the floor
6. Connect cable to junction box and indicator
7.
Calibrate the unit
Pit installations and access ramps are described in Section 2.6 and Section 2.7 on page 7.

2.2 Site Preparation

The scale must not be loaded beyond its capacity, even momentarily. Do not select a site where overweight loads would have to maneuver to avoid crossing the platform. 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 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 h conduit, will be necessary.
In operation, the scale must be level within 1/4 inch. Either choose a site avoid excessive shimming, or modify the floor at the chosen site to meet this standard.

The following paragraphs present instructions for installing and adjusting the scale feet and mounting plate installation.

2.4.1 Installing and Adjusting Feet

For load cell protection during shipping, the scale feet are shipped detached from the load cells. The feet are secured to the bottom of the shipping pallet along with the load cell cable, strain relief fitting and product literature. Remove all parts from the envelope.
Screw one foot into each load cell and turn all t of the deck. Then unscrew each foot three complete turns.
Place a spirit level on the deck. Adjust any 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.

2.4.2 Mounting Plate Installation

For permanent applications, the scale should be secured to the floor to prevent sideways movement. Two mounting 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 appro
ximately one inch off the floor. Slide mounting plates under two diagonally opposed feet. Lower the scale back to the floor, and position the plates as shown in Figure 2-2 so that the bolt down holes are accessible from above.
Using the mounting plates as templates, drill pilot holes into the floor for suitable anchor bolts. Bolt th the floor using 1/2 inch anchor bolts (3/4 inch bolts for 20K and 30K-lb capacity scales). 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

2.5.1 Electrical Interface to Indicator

Twenty feet of 6-wire cable to connect the scale to the weight indicator is supplied with each scale. The cable must be routed to the indicator in a manner that will protect the cable from damage. Two methods of cable protection in non-washdown applications are shown. When planning cable routing with either of these two methods, leave a loose coil of excess cable under the scale to facilitate future lifting of the scale for servicing or cleaning.
When the interface cable is protected and in its final position, complete connections to the indicator. See indicator installation manual for wiring information.

2.6 Pit Installation

Any of the RoughDeck models can be installed in a shallow pit using the optional RoughDeck 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 2-5. Section Showing Installed Heavy Capacity (HP-H Model) RoughDeck and Pit Frame
Site Considerations
Debris, floor sweepings, or material spills may accumulate in the pit and interfere with scale operation. You should
periodically clean the pit. All RoughDeck models have threaded holes for eye bolts so the scale can be easily lifted
from the pit.
Weight overloads, even momentary ones such as driving a loade
d forklift over a scale corner, will damage load
cells. Plan the pit location out of main traffic areas to prevent such accidental damaging overloads.

Access ramps for RoughDeck 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 attached to the scale on one of the tw longitudinal axis of the load cells. For example, the scale shown in Figure 2-5 could have an access ramp on the left side as shown, and/or on the right side. The top and bottom sides, will not

3.0 Adjustments and Calibration

3.1 Mechanical Adjustments

To accommodate minor floor unevenness, 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. If the application requires the feet to be secured, use Teflon tape or Loctite.
When adjusting scale feet, use care to prevent scale foot from bottoming out against the underside of the load cell. Also, the foot stem may be damaged by bendi 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".

3.2 Corner Correction

All assembled RoughDeck 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. This process is known as trimming.
Remove the junction box cover and identify the correct load cell terminal corner (labeled CELL 1, CELL 2, and so on). See Figure 4-4 on page 11 for scale deck corner numbering.
The indicator must be connected and calibrate approximately, but it need not indicate the exact weight value. A test weight will be required. The
recommended test weight for all RoughDeck
models is 25% of scale capacity: for example, 500 lbs for 2K-lb models, 5000 lb for 20K-lb models.
With no weight on the scale, zero the indicator. Then turn all four
potentiometers (shaded areas of Figure ) to increase the reading until a clicking sound is heard maximum signal from each load cell.
With all potentiometers at full signal, place the test weight ov the process for each of the other three corners. The load cell with the lowest corner reading will be used as a reference point and will not be trimmed.
Next, place the test weight over one of the other three co output down to the reference cell output. Repeat this procedure with the other two high corners.
Adjustments are somewhat interactive, and adjusting the especially in smaller scale decks. Rezero the indicator and repeat the test until all corners read within ±.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 t
