INTRODUCTION

This manual contains installation, operation and maintenance instructions for the DEFENDER 3000 Series Floor

Scale.

SAFETY PRECAUTIONS

Please follow these safety precautions:

•Never operate in hazardous areas.

•The foundation at the installation site must be capable of safely supporting the weight of the

floor scale plus the weight of the maximum load.

•Ensure that vibrations due to machines near the installation site are kept to a minimum. This

applies also when the floor scale is integrated into conveying systems.

INSTALLATION

CAUTION: THE FLOOR SCALE IS VERY HEAVY.

ALWAYS USE AN APPROPRIATE HOIST TO LIFT IT FROM THE PACKAGING

OR TO MOVE IT INTO THE REQUIRED POSITION.

Unpacking

1. Remove the outer packaging

materials from the top and sides

of the floor scale.

2. Install the two included eye bolts

into holes in top of platform.

(See Figure 1.)

3. Lift the floor scale from the

packaging material, see caution

notice.

Positioning

Ensure the surface is flat in the area where the scale will be positioned, especially in the region of the load cell feet.

Small differences in height can be compensated by adjusting the load cell feet.

1. If an Indicator is included with the floor scale, ensure that it is kept with the floor scale during positioning as

there may be an attached connecting cable.

2. With the floor scale positioned over the final work area, remove the 4 shipping feet (if installed).

3. Install the 4 load cell feet (if not already installed).

4. Lower the scale on to the final work area.

5. Check that the floor scale is level; check that the 4 feet are in contact with the floor; make adjustments by

rotating the nuts on the load cell feet. Use an external level.

6. Ensure that the floor scale’s output cable does not become trapped or crushed during lifting or positioning.

Connecting an Indicator

Certain Floor Scale systems will have an Indicator already attached to the cable end. If the Indicator is not

attached or if the Indicator is purchased separately follow the steps listed below to make the proper connections.

1. Route the Floor Scale cable to the position where

the Indicator will be mounted.

2. Consult the installation instructions of the Indicator

to properly attach the cable connections inside the

Indicator,

3. The Signal names of the Floor Scale wires are

shown in Table 1, Floor Scale Wiring Color Code.

Caution: Ensure that the cable is protected against

possible damage when routed to the

Indicator.

OPERATION

For setup, calibration and proper operation, refer to the instruction manual supplied with the indicator. Refer to the

specifications section of the floor scale for capacity, and readability information.

For continued best operating performance:

•Avoid falling loads, shocks and hard lateral impacts

•When weighing, all items should be centrally located on the floor scale and not

over hanging the sides or the ramps.

•Verify the calibration of the floor scale system at regular intervals.

Operating Limits

Although the floor scales have extremely rugged construction, certain load limits must not be exceeded. Depending

on the type of loading, the maximum safe static load, i.e. the maximum admissible loading, is shown in Table 2.

MAINTENANCE

Daily Checks

•Check that the rocker feet are properly seated in the holes of each load cell.

•Check that the 4 feet are in contact with the floor.

•Check that the scale is free from debris, especially under the edges of the scale.

•Check that there is no damage to the connecting cable.

Cleaning

Risk of Electrical Shock

Disconnect the power source before cleaning the scale with any liquids.

Maintenance of the floor scale is limited to regular cleaning.

– Wipe surfaces with a damp cloth.

– Use only common household cleaning agents.

– Never use water spray or high pressure cleaners.

When using optional Ramps or Foot Plates:

– Keep the air gap at the edge of the Floor Scale free of debris.

Installation of Optional Foot Plates and Ramps

Plates are required for certifiable installations. Installation of each Ramp also requires the installation of one set of

Foot Plates. Foot Plates are available separately and are included with the Ramp accessory kit. Refer to Figure 3

for mounting of the Foot Plates and Ramps. Installation of Floor Plates and Ramps must be done before final

placement of the Floor Scale.

Figure 3. Optional Foot Plate and Ramp Installation

Notes: 1. Expanding bolts require 12.5mm diameter holes drilled 60mm deep into the floor surface.

2. Foot Plate center to center dimensions W and L are shown in Table 6.

3. The Floor Scale must be positioned so the load cell feet rest within the large holes of the Foot Plates.

4. Ensure that a free air gap exists between the sides of the Floor Scale and the edges of the Ramps.
