INTRODUCTION
This manual covers installation, and maintenance instructions for the Ohaus Defender 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.
INSTALLATION
Unpacking
Unpack and inspect the product to make sure that all components have been
included. The package includes the following:
- Defender™ Series Base
- Weighing Pan
- User Guide
When purchased as a complete Defender Series Scale, the package will also include:
- Indicator
- Column Assembly
ASSEMBLY
Weighing Pan
Remove the shipping spacers, and place the weighing pan securely over the
rubber load pads on the top frame of the base.
Note: Not included with some models.
Wiring Connections
When connecting the base to an Ohaus indicator equipped with the matching
circular connector, push the base connector onto the indicator connector and
turn the locking ring clockwise to lock it in place.
When connecting the base to an indicator that does not have the matching
connector, install the optional load cell cable adapter (P/N 30429931sold
separately) to the indicator using the wiring codes in Table 1. Then attach
the load cell cable to the cable adapter.
Note: As an alternate wiring method, cut off the connector, strip the
wires and attach them to the indicator using the wiring codes in Table 1.
- Detailed instructions that describe how to prepare the load cell cable for connection to the terminal block inside an indicator.
- The extension cable accessory (P/N: 30429931) cannot be used if the scale will be used in a legal for trade or legally controlled application, because there is no provision to seal the connection between the indicator and platform.

Selecting the Location
Level the base by adjusting the four leveling feet until the bubble in the
level indicator is centered.
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.
-
A 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.
To maintain surface integrity, do not allow debris to remain on the surface of the painted or stainless steel base frame. -
Remove the pan and use fresh water to clean the base frame surface of any debris. Dry the base with a clean cloth or allow to air dry before replacing the pan. Repeat daily for best care.
