Mounting

− When mounting the container it is important to ensure that no sudden heavy
loads are applied to the module, for instance when lowering it onto the sup-
ports. Even transient loads can damage the load cell if they exceed its limit
values.
NOTE
The factory-fitted overload stop is designed for handling overloads dur-
ing normal operation. It is not designed to deal with short, sharp loads
imposed during mounting, as these commonly amount to a multiple of
the permissible limit values.
− In the case of statically undefined supports, non-uniform loading of the
modules occurs due to flexibility as the load is taken up or due to inaccu-
racy in the height adjustment. This non-uniformity should be checked on the
individual load cells by applying an excitation voltage and comparing the
output voltages. To prevent overloads, any large non-uniformity should be
compensated for by inserting shims under the supports that are least loa-
ded.
− When tanks are heavy or mounting conditions are unfavorable, the use of
mounting aids such as auxiliary supports or lifting equipment is recommen-
ded.
− The weighing modules must be installed so that they are not exposed to lat-
eral forces in the initial state. This means the built-in pendulum support
must be aligned as near to the perpendicular as possible. This is the case
when the foundation and tank joint are horizontal and the fastening holes on
the foundation and container joint are suitably aligned.
− The upper module plate and lower module plate should be firmly fastened
to the foundation and tank respectively (applies only to modules nondis-
torted installed on the support).
− The fitted EEK4 grounding cable is used to protect against welding currents
that can damage the electronic parts of the transducers.
