Load Cell Dummies
Load cells are sensitive sensors. To protect them from damage, they should only be
handled as late as possible for installation and transport. During installation and
transport, these should be replaced by dummies or phantoms. Dummies can be
constructed as follows for example:
1. A replica of the mounting element using a welded construction.
A pipe or any other steel profile can be welded between two plates with the
respective hole format for the fastening bolts. The overall height
corresponds with the installation height of the mounting element. This is
the most stable and secure version. Rough assembly work can be
performed.
2. Using a SIWAREX R Combi-mounting unit.
The Combi-mounting units are supplied as completely assembled units. The
units are set at the approximate installation height for an operational unit.
Slight adjustments can be made during the installation.

Load Cell Handling
DANGER
Load cells and mounting units are not machine elements that are constructed
using standard safety factors. It is therefore absolutely necessary to prepare for the
potential danger with respective supports or other means of protection.
CAUTION
To protect against undesirable electrical current, such as static discharge that can
occur during welding or which can be caused by lighting for example, the load
cells should be bridged with highly flexible grounding cable (e.g. SIWAREX R
ground cable 7MH3 701-1AA1).
SIWAREX R load cells may only be installed and connected by qualified personnel.
Load cells are precision components and are to be handled carefully. Pay special
attention during transport and assembly.
CAUTION
Mechanical jolts or dropping could irreparably damage the load cells.
Load cells are not to be carried by their connecting cables.
