Mounting

 When fitting the tank, vessel or silo, ensure that e.g. when lowering it onto
the bearing points no shock loads act upon the module. Even short term
loads that exceed the load cell limit values can result in damage to the load
cell.
 For heavy containers or unfavourable fitting conditions, the use of
appropriate fitting aids (auxiliary supports, lifting devices) is required.
 Lower module plate and upper module plate are to be firmly connected
with the foundations or tank connection.
 The weighing modules must be assembled such that, in their original state,
they are free from lateral forces. The pendulum bearing version requires
the fitted pendulum bearing to be aligned exactly vertically, if possible. This
is the case, if foundations and tank connection are horizontal and the
mounting bores on the basic construction and the container connection are
sufficiently aligned. Slotted holes in the module plates facilitate alignment.
 For protection against welding currents which may destroy the electronic
components of the transducer the fitted EEK4 ground cable is provided.
 Especially in the case of a statically indefinite bearing uneven loading of
the modules can occur due to an insufficiently precise height adjustment.
This unevenness is to be checked on the individual load cells by applying
an excitation voltage and comparing the output voltages. In order to avoid
any overloads, major unevenness is to be compensated for by inserting
spacer plates on the bearings with the lowest loads.
Mounting of the load cell
In order to assemble the load cell into the weighing module the pre‐fitted
dummy needs to be removed.
