1 Safety instructions
In cases where a breakage would cause injury to persons
or damage to equipment, the user must take appropriate
safety measures (such as fall protection, overload protec
tion, etc.). For safe and trouble‐free operation, weighing
modules 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 pre
vention regulations. In particular you should take into ac
count the limit loads quoted in the specifications.
Use in accordance with the regulations
HLCM... 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 load cell requires proper transportation,
correct storage, assembly and mounting and careful
operation and maintenance.
General dangers due to non‐observance of the
safety instructions
The HLCM... weighing modules correspond to the state
of the art and are fail‐safe. The weighing modules can

Safety instructions
4A1140-4.0 HBM: public HLCM…
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.
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 minimize 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 ma
terials 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

Safety instructions
HLCM… A1140-4.0 HBM: public 5
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

General
HLCM… A1140-4.0 HBM: public 7
3 General
HBM supplies HLCM... weighing modules with maximum
capacities of 110 kg; 220 kg, 550 kg, 1.1 t, 1.76 t, 2.0 t,
2.2 t and 4.4 t. They are mainly designed for tank weigh
ing applications and they are equipped with a lift‐off se
curing device.
The modules consist of a base plate, the load cell com
plete with load application elements, and the cover plate.
A pendulum support is used for the load application, pro
viding compensation for horizontal load shifts (as, for ex
ample, can arise through thermal strain). The weighing
modules are pre‐assembled and supplied with grounding
cable.

Mounting instructions
8A1140-4.0 HBM: public HLCM…
4 Mounting instructions
SIt should be ensured that the mounting / siting sur
faces are clean, flat and level. Depending on the
installation circumstances, any levelling error can be
compensated for example by suitable wedges and
compensating plates (weld on) or by grinding away
the mounting surface.
Important
On no account the module plates must be grind off.
SThe foundation/base frame must be sufficiently stiff so
that no impermissible deformations (e.g. deflections)
occur on loading.
SIn order to keep the mounting free of straining forces,
the fastening holes on the base frame and the tank
joint must be sufficiently in alignment.
SUniform loading on the support points should be pro
vided where possible. Correct adjustment of the
height on the supporting points must be ensured
(have compensating shims ready). This is especially
important for statically undefined supports.

Mounting
HLCM… A1140-4.0 HBM: public 9
5 Mounting
SThe module is delivered with lifted cover plate. Prior to
mounting, the cover plate has to be lowered by un
screwing the nut.
SIt 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.
SWith statically undefined supports, non‐uniform load
ing of the modules occurs due to flexibility as the load
is taken up or due to inadequate accuracy 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, large non‐uniformities should
be compensated by inserting shims under those sup
ports which are least loaded.
SWith heavy tanks or unfavorable installation condi
tions the use of mounting aids (auxiliary supports, jack
equipment) is recommended.
SThe weighing modules should be mounted such that
are free of transverse forces in the initial state. This
means that the mounted pendle support must be lined
up as near to the perpendicular as possible. This is
the case when the foundation and tank joint are hori
zontal and the mounting holes on the foundation and
the tank are sufficiently aligned.
SThe mounting plate and the cover plate should be
firmly fixed to the foundation, respectively the tank
joint.

Mounting

SAs protection against welding currents that can dam
age the electronic parts of the load cell, it is recom
mended that the EEK4 grounding cable is used.
SIn load cells with an additional outer braided wire over
the cable (item no. K-HLCM with option B2, together
with codes 3R, 6R or 12R), this cable is only used for
protection against increased mechanical stress (e.g.
damage caused by gnawing rodents). To avoid acci
dental energization, the outer braided wire has to be
connected to potential equalization at least once. This
outer braid is not used to shield the load cell. The
inner braid of the load cell cable is used for shielding.
Information
If the load cell is to be replaced, the upper module plate
can be lifted by max. 1.5 mm.
Lock the nut in place to hold the upper module plate in
this position. Dismounting the tank itself is not required.
When replacing the load cell, the following tightening
torques of the fastening screws must be considered
110 kg - 2.0 t electrogalvanized 130 NVm
stainless 90 NVm
2.2 t - 4.4 t electrogalvanized 400 NVm

6 Operation
SDust, dirt and other foreign bodies must not be
allowed to collect in such a way that movement of the
transducer is restricted.
SThe load introduction device (pendle bearing) applies
restoring forces which have a self‐centering effect in
the case of transverse forces. If these are exceeded,
an inadmissibly large inclination of the pendle bearing
and thus incorrect measuring results or damage to the
load introduction elements or the load cell can result.
SLateral displacements which exceed the maximum
permissible value should be avoided by aligning the
other modules appropriately, or should be absorbed
by other stops or retention devices.

8 Connection
Load cells can be connected either to Carrier‐frequency‐
amplifiers or DC‐amplifiers.
The load cell connection cable should be routed so that
any condensed water or dampness forming on the cable
can drip off. It must not be led to the load cell. In addition,
it must be ensured that no dampness can penetrate the
open end of the cable.

SDo not route these measurement cables in parallel to
power and control lines. If this is not possible, protect
the measurement cable (e.g. by means of
steel‐sheathed pipes).
SAvoid the leakage fields of transformers, motors and
contactors.
Parallel connection of several weighing modules
The load cells of the weighing modules can be connected
electrically in parallel by connecting up the wire ends with
the same color . For this HBM offers the junction boxes
VKK... or for use in intrinsically safe circuits and hazard
ous areas the junction box VKEX (EEx e II T6). The out
put signal will then be the mean value of the individual
output signals.
CAUTION
In such cases, an overload situation on a single load cell
cannot be detected from the output signal.
Cable extension
For extending cables, only use shielded low capacity
measurement cables (measurement cables provided by
HBM1) meet these requirements). Ensure that there is a
perfect connection with the lowest possible transition re
sistance. If you use the 6‐wire circuit, you may neglect
any interference by a change in the resistance of the ex
tension cables. However, if you extend the cable in a
