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.
