Safety instructions
HLC / HLC-P A01130_07_Y00_00 HBM: public 3
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.

Safety instructions
4A01130_07_Y00_00 HBM: public HLC / HLC-P
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,

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.

Important
Missing washers and a base plate strength which is too low, cause most faults
that occur during load cell use. In particular, this applies to the strength of the
base plate which has a direct influence on the “Hysteresis error” stated in the
Specifications.

Load introduction
10 A01130_07_Y00_00 HBM: public HLC / HLC-P
5 Load introduction
Loads should act as precisely as possible in the load direction. Torsion
moments, off‐centre loads, as well as transverse or lateral forces cause mea
surement errors and may damage the load cell permanently. Such interfer
ences must be intercepted e.g. by stay rods or guide rollers, with these ele
ments not being permitted to take up any load or force components.
In order to minimize error interferences due to load introduction, HBM offers
various proven load introductions for load cell types HLCB... (versions with
counterbore + thread), depending on the mounting situation, see chapter 8.1
“Mounting accessories for HLC B”, page 21
The load cell type HLCA... (version with tapped through hole) is provided for
use with threaded bolt and locknut. Depending on actual use, the threaded bolt
can be screwed into the tapped through hole in both directions. The locknut will
secure the threaded bolt on both surfaces. Please note the required locknut
torques from 40 N⋅m ... 54 N⋅m.

Electrical connection
HLC / HLC-P A01130_07_Y00_00 HBM: public 11
6 Electrical connection
Load cells can be connected either to carrier‐frequency‐amplifiers or DC‐ampli
fiers.
CAUTION
Electric and magnetic fields often cause interference voltages that are coupled
into the measurement circuit.
Therefore:
SUse only shielded, low-capacitance measurement cables. Measurement
cables from HBM1) or couplings for HLC-P from HBM2) meet these
requirements.
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.
Load cells can be connected electrically in parallel by connecting up the same
color wire ends of the load cell connection cables. The output signal will then
be the mean value of the individual output signals.
1) for example, HBM extension cable, 6-wire:
- CABA1 (cable reel, order no. 1-CABA1/20 = 20 m or 1-CABA1/100 = 100 m long), gray
- CABE2 (cable reel, order no. 1-CABE2/20 = 20 m or 1-CABE2/100 = 100 m long), blue
- CABT1 (cable reel, order no. 1-CABT1/50 = 50 m or 1-CABT1/200 = 200 m long), red, TPE
- CABM1 (cable reel, order no. 1-CABM1/200 = 200 m, braided wire over TPE
2) for example HBM couplings for M12 (x1):
- KAB168 (order no. 1-KAB168-5 = 5 m or 1-KAB168-20 = 20 m), IP67, black, PUR
- KAB175 (order no. 1-KAB175-3-1 = 3 m or 1-KAB175-6-1 = 6 m long), IP68/IP69K, black,
PUR

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 resistance.
If you use the 6‐wire circuit, you may neglect any interference by a change in
the resistance of the extension cables. However, if you extend the cable using
the 4‐wire technique, the characteristic value deviation can be removed by
adjustment. Temperature influences will not be compensated.
