Introduction
This manual contains installation, operation and maintenance instructions for the DEFENDER 2500 Series Drum Scale.
Safety Precautions
CAUTION: Read all safety warnings before installing, making connections, or servicing this equipment. Failure to comply with these warnings could result in personal injury and/or property damage. Retain all instructions for future reference.
- Verify that the AC adapter's input voltage range and plug type are compatible with the local AC mains power supply.
- Make sure that the power cord does not pose a potential obstacle or tripping hazard.
- Do not position the equipment such that it is difficult to reach the power connection.
- Operate the equipment only under ambient conditions specified in these instructions.
- Do not operate the equipment in wet, hazardous or unstable environments.
- The foundation at the installation site must be capable of safely supporting the weight of the Drum Scale plus the weight of the maximum load.
- Ensure that vibrations due to machinery near the installation site are kept to a minimum.
- Disconnect the equipment from the power supply when cleaning.
- Use only approved accessories and peripherals.
- Service should only be performed by authorized personnel.
Intended Use
Use the equipment exclusively for weighing, as described in these operating instructions. Any other type of use and operation beyond the limits of technical specifications, without written consent from OHAUS, is considered as not intended. This instrument complies with current industry standards and the recognized safety regulations; however, it can constitute a hazard in use. If the instrument is not used according to these operating instructions, the intended protection provided by the instrument may be impaired.
Installation
[WARNING] The drum scale base is heavy -- please move the drum scale carefully!
Unpacking
1. Remove the outer packaging materials from the Drum Scale.
2. Lift it up to vertical by handles.
3. Move it into the required position on its wheels.
Figure 1 and Figure 2 illustrate the unpacking process, showing the scale body, cartons, scale feet, plate, and indicator components.
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.
- The Indicator is included with the Drum Scale. Ensure that it is kept with the Drum Scale during positioning and protected along with the attached connecting cable.
- Lower the scale base carefully onto to the floor in the final work area.
- Check that the Drum Scale is level; check that the 4 feet are in contact with the ground; make adjustments by rotating the nuts on the load cell feet or rotating the foot bolt head with slot with a screwdriver from the top. Use an external level.
- Ensure that the Drum Scale's cables do not become trapped or crushed during lifting or positioning.
Connecting an Indicator
Align the tab on the inside of the loadcell connector socket on the indicator to the slot on the loadcell cable connector end. Insert the cable connector end into the indicator and then fasten it by rotating the locking collar.
Caution: Pay attention on PINs when connecting to the indicator, otherwise the connector may be broken. 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 Drum 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 Drum Scale and not overhanging the sides or the ramps.
- Verify the calibration of the Drum Scale system at regular intervals.
Operating Limits
Although the Drum 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 permissible 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 ground.
- 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 Drum Scale is limited to regular cleaning.
- Wipe surfaces with a damp cloth.
- Use only common mild cleaning agents.
- Never use water spray or high pressure cleaners.
- Keep the air gap at the bottom of the Drum Scale free of debris.
