Safety instructions
Z6AM A01559_03_Y00_00 HBM: public 3
1 Safety instructions
In cases where a breakage would cause injury to persons or damage to equip
ment, the user must take appropriate safety measures (such as fall protection,
overload protection, etc.). For safe and trouble‐free operation, weighing mod
ules must not only be correctly transported, stored, sited and installed but must
also be carefully operated and maintained.
It is essential to comply with the relevant accident prevention regulations. In
particular you should take into account the limit loads quoted in the specifica
tions.
Use in accordance with the regulations
Z6AM type weighing modules are conceived for weighing applications. Use for
any additional purpose shall be deemed to be not in accordance with the
regulations.
In the interests of safety, the weighing modules should only be operated as
described in the Mounting Instructions. It is also essential to observe the
appropriate legal and safety regulations for the application concerned during
use. The same applies to the use of accessories.
The weighing modules are not safety elements within the meaning of its use as
intended. Proper and safe operation of this transducer requires proper
transportation, correct storage, assembly and mounting and careful operation
and maintenance.
General dangers due to non‐observance of the safety instructions
The Z6AM weighing modules correspond to the state of the art and are
fail‐safe. The weighing modules can give rise to residual dangers if they are
inappropriately installed and operated by untrained personnel.
Everyone involved with the installation, commissioning, maintenance or repair
of a force transducer must have read and understood the Mounting Instructions
and in particular the technical safety instructions.
Safety instructions
4A01559_03_Y00_00 HBM: public Z6AM
Residual dangers
The scope of supply and performance of the weighing modules covers only a
small area of weighing technology. In addition, equipment planners, installers
and operators should plan, implement and respond to the safety engineering
considerations of weighing technology in such a way as to minimise residual
dangers. Prevailing regulations must be complied with at all times. There must
be reference to the residual dangers connected with weighing technology.
Environmental conditions
In the context of your application, please note that all materials which release
chlorine ions will attack all grades of stainless steel and their welding seams. In
such cases the operator must take appropriate safety measures.
Prohibition of own conversions and modifications
The weighing modules must not be modified from the design or safety
engineering point of view except with our express agreement. Any modification
shall exclude all liability on our part for any damage resulting therefrom.
Qualified personnel
These weighing modules are only to be installed by qualified personnel strictly
in accordance with the technical data and with the safety rules and regulations
which follow. It is also essential to observe the appropriate legal and safety
regulations for the application concerned. The same applies to the use of
accessories.
Qualified personnel means persons entrusted with the installation, fitting,
commissioning and operation of the product who possess the appropriate
qualifications for their function.
Accident prevention
Although the specified nominal capacity in the destructive range is several
times the full scale value, the relevant accident prevention regulations from the
trade associations must be taken into consideration.

3 General
HBM supplies Z6AM weighing modules for max. capacities from 50 kg to
200 kg and 500 kg. The weighing modules are designed mainly for use in
weighing applications.
These weighing modules are fitted with lateral stay rods. An integral over‐load
stop is also fitted.
The modules consist of a base plate, the load cell complete with load applica
tion elements, and the cover plate. A pendulum support is used for the load
application, providing compensation for horizontal load shifts (such as may
occur as a result of thermal strain, for example). The weighing modules are
pre‐assembled and a grounding cable is supplied.

4 Prior to mounting
SCare should be taken to ensure that all surfaces for siting and mounting are
clean, smooth and level. Depending on the mounting conditions, any level
ing error can be compensated for by using suitable wedges and compensa
tion plates (permanently welded) or by grinding away the mounting surface,
for example. On no account must the module plates be ground.
SThe base or foundation frame must be sufficiently rigid to prevent unaccept
able deformation under load (such as sagging).
SIn order to keep the mounting as free of constraining forces as possible, the
fastening holes on the foundation frame and container joint must be suitably
aligned.
SEvery effort should be made to ensure uniform loading on the support
points. Care should be taken to adjust the height on the support points cor
rectly (compensating shims need to be available). This is especially impor
tant in the case of statically undefined supports.

5 Mounting
SWhen 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.
Notice
The factory‐fitted overload stop is designed for handling overloads during nor
mal 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 val
ues.
SIn the case of statically undefined supports, non‐uniform loading of the mod
ules occurs due to flexibility as the load is taken up or due to inaccuracy in
the height adjustment. This non‐uniformity should be checked on the indi
vidual load cells by applying an excitation voltage and comparing the output
voltages. To prevent overloads, any large non‐uniformity should be com
pensated for by inserting shims under the supports that are least loaded.
SWhen tanks are heavy or mounting conditions are unfavorable, the use of
mounting aids such as auxiliary supports or lifting equipment is recommen
ded.
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 suitably aligned.
SThe upper module plate and lower module plate should be firmly fastened to
the foundation and tank respectively (applies only to modules nondistorted
installed on the support).
SThe fitted EEK4 grounding cable is used to protect against welding currents
that can damage the electronic parts of the transducers.
