1.3 Description of Swivel Caster Deck Scale System

1.3.1 Major Components

The system has two major parts:

1. Swivel caster deck scale assembly

2. Remotely mounted indicator (see indicator for operation instructions)

Figure 1.1 shows the scale deck.

Figure 1.1 Swivel caster deck scale

See the simplified block diagram in Figure 1.2.

Figure 1.2 Swivel caster deck scale system simplified block diagram

The swivel caster deck assembly consists four Avery Weigh-Tronix 5000 lb capacity

Weigh Bars, a junction box, a subframe and mounting components. See the

illustrations in the back of this manual for details of the scales construction.

2 Installation and Wiring Information

2.1 Scale Deck Installation

The surface of the scale deck should be parallel to the floor slab in the direction of daily

travel. The deck must be level front to back, in the direction of container travel and the

scale must be anchored in place with expansion bolts.

Following are the steps for installing the scale platform. See Figure 2.1.

1. Determine the scale location and position mounting base plates per outline

drawing for your system.

2. Drill holes in concrete floor and fasten base plates with 5/8" x 3" long

expansion bolts and flat washers.

3. Set a support channel on center of each base plate.

4. Place the scale platform in position with the sub-frame inside the support

channels.

5. Insert two .75" diameter bolts with washer through support channel and sub-

frame. Thread nut on bolt but DO NOT TIGHTEN.

6. Adjust scale platform to desired height using the .62" diameter bolts in each

corner and tighten the support channels to the sub-frame.

7. Center support channel on base plates and weld the base plates and support

channels together. (Repair paint finish upon completion of welding.)

8. Install interface cable between the scale platform and indicator enclosure.

Figure 2.1 Mounting illustration

2.2 Indicator

Make the necessary connections between the indicator and the scale junction box as

shown in Wiring Digram on page 8. Plug the AC power cable into the appropriate power

source, 110 V ac, 60 Hz.

Do all welding prior to installation of the interface cable.

Do not weld on or near a Weigh Bar. Excessive heat or high currents may cause

internal damage. Place welding ground on the support channel and not on the

sub-frame.

3 Operating Instructions

See the user and service manuals for the indicator used with this scale for instructions

on daily operation and calibration procedures.

SCS Operation and Maintenance Manual 5

4 Maintenance and Calibration

4.1 Caster Maintenance

1. Check casters for free movement.

2. Casters do not require lubrication.

3. Replace any faulty casters.

4.2 Weigh Bar Maintenance

1. Check for cracks or abrasions on cables.

2. Check to see that cables are not pinched or restricting scale movement.

3. Check adjustment of overload stops.

4. Remove any debris from around weigh bar suspension points. Be sure that

suspension points have no restrictions to free movement.
