5 MOUNTING
S
The module is delivered with lifted cover plate. Prior to mounting, the cover plate has
to be lowered by unscrewing the nut.
S
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 supports. Even transient
loads can damage the load cell if they exceed its limit values.
Notice
The factory‐fitted overload stop is designed for handling overloads during normal opera­
tion. 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.
S
In the case of statically undefined supports, non‐uniform loading of the modules oc­
curs due to flexibility as the load is taken up or due to inaccuracy in the height adjust­
ment. 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 sup­
ports that are least loaded.
S
When tanks are heavy or mounting conditions are unfavorable, the use of mounting
aids such as auxiliary supports or lifting equipment is recommended.
S
The weighing modules must be installed so that they are not exposed to lateral 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 suit­
ably aligned.
S
The base plate and cover plate should be firmly fastened to the foundation and tank
respectively.
S
The fitted EEK4 grounding cable is used to protect against welding currents that can
damage the electronic parts of the transducers.
