1.0 Introduction

The RoughDeck® Floor Scales are fully electronic, low profile load receivers. The RoughDeck is 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-lbs (1000–15000 Kg). The RoughDeck comes in several ve rsions, including the stainless steel HE model designed for harsh washdown environments.

All models use four corner-mounted, FM-approved load cells, with the cells recessed into the frame channels for protection. A signal-trim summing board for any necessary corner corrections is enclosed in a junction box mounted on a slide-out tray for easy access. The stainless steel models use a stainless steel NEMA Type 4X junction box. Mild steel models feature the same board housed in a standard plastic junction box. All models come pre-trimmed, and corner corrections should not be necessary.

Load cell cables are enclosed in conduit through the main channels, and held down with replaceable cable ties near 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 for minor floor irregularities. For permanent 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 with holes drilled in the deck directly above each foot for adjusting foot height with a screwdriver from above. optional equipment part numbers.

1.2 Model Designations

The model identification plate is located on the side of the frame next to the slide-out junction box tray. Include both model number and serial number when ordering replaceme nt parts.

The following model designations are used to describe the different scale versions:

• HP — Mild steel, high precision, NTEP-certified as “legal-for-trade” and FM-approved load cells.

• HP-H — 20K- and 30K-lb capacity HP models.

• SS — Non-washdown stainless steel, NTEP-certified model, for dry chemical and corrosive environments.

• HE — Washdown stainless steel, external mounted, NTEP-certified model with hermetically-sealed load

cells and NEMA 4X J-box for hostile environments.

1.3 Operating Requirements

Electrical Grounding

Load Cell Excitation

Rated Excitation: 10 VDC, Maximum Excitation: 15 VDC

Grade Level Requirements

The supporting surface for the four feet of the scale must be level within 1/4 in. of horizontal.

Safe Static Overloading Capacity

Maximum: 150% of scale capacity

Nominal Scale Height

2K–10K lb (1000–5000 Kg) models: 3.5 in (89 mm) 20K lb (10000 Kg) models: 4.0 in (102 mm) 30K lb (15000 Kg) models: 5.0 in (127 mm)

2.0 Installation

Important

2.1 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 from junction box to indicator

Calibrate the unit

Pit installations and access ramps are described in Section 2.6 and Section 2.7.

2.2 Site Preparation

Location

The scale must not be loaded beyond its capacity, even momentarily.

• Select a site where overweight loads can maneuver easily without crossing the platform.

• Avoid areas where damage could occur from side impacts of wheels or forklift tines.

• Avoid areas where falling objects could cause

• Avoid areas where water may damage a scale not

Cabling

The interface cable between the scale and the indicator must be protected against crushing, cutting, or moisture da

mage.

If the chosen site has such potential dangers, some method of protection, such as running the cable in conduit, will be required.
