Revision 09/04
Loads must be introduced precisely in the direction of measurement of the load
cells. Torsion and bending moments, excentric loading and lateral loads are
disturbance forces that lead to incorrect measurements and can cause damage if
exceeding the permitted limitations of the load cells and mounting elements.
The mounting components allow enough play in movement that thermal expansion
does not lead to lateral loading.
1.6
Welding and Installation Work
As long as installation work is not complete on the scale, the load cells should be
replaced with dummies to protect them from jolts or welding current.
CAUTION
If welding is required after installing the load cells, make absolutely sure that the
welding current is not routed through the load cells. The ground clamp of the
welder is to be securely connected in the direct vicinity of the point to be welded.
The load cells must be bridged with a grounding cable. The individual load cells are
to be disconnected. The free cable ends should be insulated.
1.7
Mounting
Load cells are never to be overloaded. Slowly put the load platform on. Especially
with load cells having lower rated loads, there is a danger that external forces
during installation, e.g. tightening counter nuts, will bend the load cell bodies.
WARNING
Proper tools are to be used for lifting the load platform. Ensure that the respective
safety regulations are followed.
NOTE
Molded brackets or eyebolts should exist on the loading platform for the proper
utilization of lifting instruments.
If overload security mechanisms are available, set them up so that the desire load
can be taken on safely. They must permit an unrestricted increase in weight up to
the set weight.
The gap between the load cell and the overload protection is to be guarded from
contamination and icing.
Overload protection is to be checked regularly during maintenance work for easy
adjustment.
