Instruction Manual

INTRODUCTION
This manual covers installation, and maintenance instructions for the Ohaus Defender™ 3000 Series Base. Please read this manual completely before installation and operation.

SAFETY PRECAUTIONS

For safe and dependable operation of this product, please comply with the following precautions:

• Operate the base only under ambient conditions specified in these instructions
• Ensure that the load cell cable does not pose an obstruction or tripping hazard
• Do not operate the base in hazardous environments or unstable locations
• Do not drop loads on the base
• Do not lift the base by the top frame; always lift from the bottom frame when moving the base
• Service should only be performed by authorized personnel

Intended Use
Use the instrument exclusively for weighing as described in the 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 of the instrument may be compromised and OHAUS assumes no liability.

INSTALLATION

Unpacking
Unpack and inspect the product to make sure that all components have been included. The package includes the following:

• Base
• Weighing Pan
• Warranty Card
• Instruction Manual

When purchased as a complete Defender 3000 Series Scale, will also include:

• 3000 Series Indicator
• Column Assembly

Assembly
Weighing Pan
Place the weighing pan securely over the rubber load pads on the top frame of the base.
Wiring Connections
Connect the load cell cable to an indicator using the wiring codes in Table 1 below. Refer to the indicator manual for information about load cell connections, setup and calibration.
Note: When purchased as a Defender Series Scale, the base is already pre- wired to the 3000 Series Indicator.
TABLE 1. SIX WIRE LOAD CELL CONNECTION.

Selecting the Location
To ensure accuracy, proper performance and safety, locate and operate the base on a stable, level surface. Avoid locations with rapid temperature changes or excessive dust, air currents, vibrations, electromagnetic fields or heat.
Level the base by adjusting the four leveling feet until the bubble in the level indicator (located at the rear of the base) is centered. A wrench may be needed to loosen the locking nut above each leveling foot. When the base is level, retighten the locking nuts up against the base to lock each foot into place.
Note: Ensure that the base is level each time its location is changed.

MAINTENANCE

Cleaning
The base components should be kept clean and free of excessive material build up.

• Damp cloth with water and a mild detergent may be used to wipe clean the external surfaces—do not use acids, alkalis, strong solvents or abrasive materials and chemicals

Troubleshooting
Aside from installing components and leveling adjustments, the Defender Series Base does not require any other adjustments as shipped from the factory.
Operational difficulties that may be encountered can often be traced to simple causes such as:

• Loose or incorrect wiring connections
• Obstructions to the base frame
• Unstable environments
• Incorrect calibration or setup of the indicator
