1 Safety instructions
Intended use
Load cells of the PW15AH…type series are designed for technical weighing
applications within the load limits detailed in the specifications. Any other use is
not the intended use.
The load cells may only be installed by qualified personnel in compliance with
the specifications and with the safety requirements and regulations of these
mounting instructions. It is also essential to observe the applicable legal and
safety regulations for the application concerned. The same applies to the use
of accessories.
Load cells are not intended for use as safety components. Please also refer to
the “Additional safety precautions” section. Proper and safe operation of the
load cells requires proper transportation, correct storage, siting and mounting,
and careful operation.
Load-carrying capacity limits
Comply with the data in the technical data sheets when using the load cells.
The respective specified maximum loads in particular must never be exceeded.
Do not exceed the values stated in the technical data sheets, for example, for
Slimit load
Slateral load limiting
Sbreaking loads
Stemperature limits
Slimits of electrical load-carrying capacity
Note that when several load cells are installed in a scale, there is not always an
even load distribution on the individual load cells.

Safety instructions
4A02435_02_Y00_00 HBM: public PW15AH
Use as machine elements
The load cells can be used as machine elements. When used in this manner, it
must be noted that, to favor greater sensitivity, the load cell is not designed
with the safety factors usual in mechanical engineering. Please refer to the
"Load-carrying capacity limits" section and to the specifications.
Accident prevention
The applicable accident prevention regulations from employers’ liability
insurance associations must be taken into account, even though the stated
load in the destructive range is well in excess of the full scale value.
Additional safety precautions
Load cells cannot (as passive transducers) implement any (safety-relevant)
cutoffs. This requires additional components and constructive measures, for
which the installer and operator of the plant is responsible.
In cases where a breakage or malfunction of the load cells would cause injury
to persons or damage to equipment, the user must take appropriate additional
safety measures that meet at least the requirements of applicable safety and
accident prevention regulations (e.g. automatic emergency shutdown, overload
protection, catch straps or chains, or other fall protection).
The electronic processor that processes the measurement signal should be
designed so that failure of the measurement signal cannot lead to secondary
failures.
General dangers of failing to follow the safety instructions
Load cells are state-of-the-art and reliable. Transducers can give rise to
residual dangers if they are mounted, installed, used or operated
inappropriately or by untrained personnel. Everyone involved with siting,
starting up, operating or repairing a load cell must have read and understood
the mounting instructions and in particular the technical safety instructions.
Load cells may be damaged or destroyed by improper use or non-compliance
with the mounting and operating manual, these safety instructions or any other
applicable safety regulations (safety and accident prevention regulations of
employers’ liability insurance associations) when handling the load cells. Load

cells can break, particularly if overloaded. The breakage of a load cell can also
cause damage to property or injury to persons in the vicinity of the load cell.
If load cells are not used according to their designated use, or if the safety
instructions or specifications in the mounting and operating manual are
ignored, it is also possible that the load cells may fail or malfunction, with the
result that persons or property may be affected (due to the loads acting on or
being monitored by the load cells).
The scope of supply and performance of the transducer covers only a small
area of weighing technology, as measurements with (resistive) strain gage
sensors presuppose the use of electronic signal conditioning. In addition,
equipment planners, installers and operators should plan, implement and
respond to the safety engineering considerations of the weighing technology in
such a way as to minimize residual dangers. Pertinent national and local
regulations must be complied with.
Conversions and modifications
The design or safety engineering of the transducer must not be modified with
out our express permission. Any modification shall exclude all liability on our
part for any damage resulting therefrom.
Resale
If the load cell is resold, these mounting instructions must be included with the
load cell.
Environmental protection, disposal
In accordance with national and local environmental protection, material
recovery and recycling regulations, old transducers that are no longer
serviceable must be disposed of separately from normal household waste.
If you require more information about disposal, please contact your local
authorities or the dealer from whom you purchased the product.

4 Mounting and load application
4.1 Mounting instructions
When mounting the load cells, pay attention to the following:
SPlease handle load cells with care!
SLoad cells are precision sensors and so their achievable accuracy depends
greatly on their being mounted correctly!
SUse suitable hoisting gear for mounting the weighing device!
SDo not overload load cells even briefly (e.g. due to unevenly distributed
support loads)!
SWhen carrying out adjustment work that could endanger the load cells, use
supports (dummies) of equal height!
SAvoid lateral forces and torques!
SDepending on the construction, use anti-liftoff devices and limit stops if
necessary!
SProtect load cells against
- one-sided heat radiation
- the influences of subsequent welding work
- strong temperature variations!
STo prevent rapid wear, grease the force application part. Please take care
not to use too much grease, as this will cause the rubber ring of the cell to
stick (from maximum capacity >4.7 t)!
Notice
Load cells are precision measuring elements and need to be handled carefully.
Dropping or knocking the transducer may cause permanent damage. Make
sure that the transducer cannot be overloaded, including while it is being
mounted.

O-ring (provided by customer)
Even without a cable protection system, standard load cells can achieve an IP
rating of IP68/IP69K. In applications where the PVC cable of the load cell could
be chemically or mechanically attacked or destroyed, extra cable protection
can be provided using standard cable protection systems.
5.3 Shortening and extending the cable
When a six-wire configuration is used, the 6‐wire cable of the load cell can be
shortened with no adverse effect on measurement accuracy.
Use only shielded, low-capacitance measurement cables to extend cables,
making sure there is a proper connection with minimal contact resistance.
The cable of a six-wire load cell can be extended using a cable of the same
type.
5.4 Parallel connection (option)
Only single-point load cells with a compensated output (nominal (rated)
sensitivity and output resistance) are suitable for parallel connection.

Electrical connection
14 A02435_02_Y00_00 HBM: public PW15AH
5.5 EMC protection
Electrical and magnetic fields often induce interference voltages in the
measuring circuit. To ensure reliable measurement, however, the transducer
must be able to transmit signal differences of less than 1 μV to the analysis
unit without interference.
Therefore:
SUse only shielded, low-capacitance measurement cables (HBM cables fulfill
both conditions).
SDo not route measurement cables parallel to power lines or control circuits.
If this is unavoidable, protect the measurement cable, e.g. using rigid steel
conduits
SAvoid stray fields from transformers, motors and contact switches
Planning the shielding design
Due to the numerous application options and differing local constraints, we can
only provide you with general information on correct connection. The shielding
design suitable for your application must be planned locally by an appropriate
specialist. HBM load cells with shielded, round cables are EMC-tested in
accordance with EC directives and bear the CE mark.
Please note:
SConnect the whole surface of the connection cable shield to the shielding
housing of the electronics.
SIf using several load cells, connect the whole surface of the shields to the
junction box (grouping transducer signals, e.g. type VKK2 from HBM).
SFrom there, connect the whole surface of the measurement cable for the
electronics to the junction box and to the shielding housing of the
electronics.

Corrosion protection and maintenance
PW15AH A02435_02_Y00_00 HBM: public 15
6 Corrosion protection and maintenance
Protect load cells against chemicals that could attack the cable or the steel of
the housing.
Notice
Acids and all substances that release ions also attack stainless steels and their
weld seams.
The resulting corrosion could cause the transducer to fail. If this is the case,
you must provide appropriate means of protection.
The transducer is basically maintenance free.
Dust, dirt and other foreign matter must not be allowed to accumulate
sufficiently to divert some of the measuring force onto the housing, thus
distorting the measured value (force shunt).
Do not use hard or pointed objects to clean the transducer. The transducer
achieves an IP rating of IP68 (test conditions: 100 hours under 1 m water
column) and IP69K (water at high pressure, steam cleaning), as per
DIN EN 60529. The transducer is therefore suitable for wet cleaning. Despite
this, the transducer should be protected against the long-term effects of
moisture.
