1 Safety instructions
In cases where a breakage may cause injury to persons or damage to equip
ment, the user must take appropriate safety measures (such as fall protection,
overload protection, etc.). Safe and trouble‐free operation of the load cells re
quires proper transportation, correct storage, assembly and mounting as well
as careful operation and maintenance.
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
HLC type load cells have been designed for weighing applications. Use for any
additional purpose shall be deemed to be not in accordance with the regula
tions.
To ensure safe operation, the load cells should only be used 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 HLC load cells can be used as machine components (e.g. with tank
weighing). Please note in these cases that, in order to provide a high sensitiv
ity, the load cells have not been designed with the safety factors normally
applied in machine design. The load cell is not a safety element within the
meaning of its use in accordance with the regulations. The measuring signal
processing electronics has to be designed in such a way that with a measuring
signal failure no damages can occur.
General dangers due to non‐observance of the safety instructions
The HLC load cells correspond to the state of the art and are fail‐safe. The
load cells 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 load cell 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 load cells covers only a small part
of weighing technology. In addition, equipment planners, installers and operat
ors should plan, implement and respond to the safety engineering considera
tions of weighing technology in such a way as to minimize residual dangers.
Prevailing regulations must be complied with at all times. There must be refer
ence to the residual dangers connected with weighing technology.
Environmental conditions
In the context of your application, please note that acids and all materials
which release (chlorine) ions will attack all grades of stainless steel and their
welding seams. This may result in corrosion which can lead to the failure of the
load cell. In such cases the operator must take appropriate safety measures.
Prohibition of own conversions and modifications
The load cells 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 load cells are only to be installed by qualified personnel strictly in accor
dance with the specifications and with the safety rules and regulations which
follow. It is also essential to observe the appropriate legal and safety regula
tions for the application concerned. The same applies to the use of acces
sories.
Qualified personnel means persons entrusted with the installation, fitting, com
missioning and operation of the product who possess the appropriate qualifica
tions for their function.
Accident prevention
Although the specified maximum capacity in the destructive range is several
times the full scale value, the relevant accident prevention regulations from the
trade associations must be complied with. Take into consideration the values
specified in particular in chapter 7 for
Slimit loads,

Smax. longitudinal forces,
Smax. transverse forces.
Option: Explosion proof version
SUsers must comply with all relevant erection regulations during installation.
SThe installation conditions listed in the certificate of conformity and/or type
examination certificate must be complied with.

2 Used markings
2.1 The markings used in this document
Important instructions for your safety are specifically identified. It is essential to
follow these instructions in order to prevent accidents and damage to property.
Symbol Significance
CAUTION This marking warns of a potentially dangerous
situation in which failure to comply with safety
requirements can result in slight or moderate physical
injury.
Important
This marking draws your attention to important
information about the product or about handling the
product.
Emphasis

4 Mounting
Please pay attention on the following points for the mounting of load cells:
SDo not overload load cells, not even temporarily.
SThe mounting surface must be horizontal, flat across the entire surface, and
absolutely clean. Dust, dirt, and other foreign matter should not collect such
that they have a detrimental effect on the mobility of load cells, thus
falsifying the measured value.
SWhen mounting, or immediately after mounting, each load cell should be
bridged by means of a twisted copper cable (e.g. EEK... by HBM = approx.
16 mm2). In this way, you prevent damage caused by welding currents.
SLoad cell grounding reduces the risk of load cell damage due to lightning.
SIn load cells with an additional outer braided wire over the cable (item no.
K-HLCB2 with option 5, code 3R, 6R or 12R), this cable is only used for
protection against increased mechanical stress (e.g. damage caused by
gnawing rodents). To avoid accidental 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.
CAUTION
Never load in a direction opposite to the load direction specified (see arrow on
the load introduction front of the load cell). This would cause measurement
errors and the damage of the mounting bolts. If load direction is correct, the
load cell output signal is positive.
