3 Mounting
• lt should be ensured when mounting the tank that, for example, no shock
loads are applied to the module when lowering it onto the supports. Even
short‐term loads which exceed the load cell limits can lead to damage.
• With heavy tanks or unfavorable Installation conditions the use of mounting
aids (auxiliary supports, jack equipment) is recommended.
• The mounting plate and upper module plate should be firmly fastened to the
foundation, respectively the tank joint.
• The weighing modules should be mounted such that they are free of trans­
verse forces in the initial state. This means that the mounted rocker pin load
cell must be lined up as near to the perpendicular as possible. This is the
case when the foundation and tank Joint are horizontal and the mounting
holes on the foundation and the tank are sufficiently aligned. As supplied,
the transport locking plate is fitted such that this is the case, thus allowing
hole patterns to be checked easily.
• A anti‐liftoff device can be effected by screwing in a threaded rod of an ap­
propriate length and checking with a nut in the lower module plate. The
threaded rod must have a working clearance in a though hole of the vessel
base. Two further nuts are to be checked over a washer with approx. 2 mm
working clearance relative to the vessel base.
• As protection against welding currents that can damage parts of the trans­
ducer, it is recommended that the EEK4 Earthing Cable is used (included in
the supply).
• With statically undefined supports, non‐uniform loading of the modules oc­
curs due to flexibility as the Ioad is taken up or due to inadequate accuracy
in the height adjustment. This non‐uniformity should be checked an the indi­
vidual Ioad cells by applying an excitation voltage and comparing the Out­
put voltages. To prevent overloads, large non‐uniformities should be com­
pensated by inserting shims under those supports which are least loaded.
