SAFETY INSTRUCTIONS
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 specifi
cations 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 applica
tion concerned. The same applies to the use of accessories.
Load cells are not intended for use as safety components. Please also refer to the “Addi
tional 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 respec
tive 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.
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" sec
tion and to the specifications.
Accident prevention
The applicable accident prevention regulations from employers’ liability insurance associ
ations 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-compli
ance 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, partic
ularly 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 without our
express permission. Any modification shall exclude all liability on our part for any dam
age resulting therefrom.
Resale
If the load cell is resold, these mounting instructions must be included with the load cell.

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!
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.
4.2 Load application
Clamp the load cells firmly at the mounting holes and apply the load at the other end. The
recommended screws and tightening torques can be found in the table below:

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 stan
dard 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.
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 a few μV to the analysis unit without interference.
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.

PW15AH
ELECTRICAL CONNECTION
12
HBM load cells with shielded, round cables are EMC-tested in accordance with the
EU Directive and bear the CE mark. Voltage surges as per EN 61000-4-5 can give rise to
deviations from the load cell’s specified accuracy. These surges in plants are caused by
lightning strikes or switching operations in power circuits, for example, and disappear
again when interference is no longer active. This is particularly evident with cables over
30 m long or if the equipment is used outdoors. Customers should take additional pre
cautions in these cases.
Please note:
SConnect the connecting cable shield all over the surface of the shielding electronics
housing. When using several load cells, connect the shields all over the surface of the
junction box (combination of transducer signals, e.g. type VKK2 from HBM). From
there, connect the measurement cable for the electronics over the surface of the
junction box and the shielding electronics housing.
SThe shield of the connecting cable must not be used for discharging potential
differences within the system. You must therefore lay sufficiently dimensioned
potential equalization lines to compensate for possible potential differences.
SUse shielded low-capacitance measurement cables only (HBM cables fulfill these
conditions).
SDo not route measurement cables parallel to electric cables, especially power lines
and control circuits. If this is not possible, protect the measurement cable, for
example with steel conduits.
SAvoid stray fields from transformers, motors and contact switches.

PW15AH
CORROSION PROTECTION AND MAINTENANCE
6 CORROSION PROTECTION AND MAINTENANCE
Protect load cells against chemicals that could attack the cable or the steel of the hous
ing.
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 pro
vide 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.

Zusätzliche Sicherheitsvorkehrungen
Die Wägezellen können (als passive Aufnehmer) keine (sicherheitsrelevanten)
Abschaltungen vornehmen. Dafür bedarf es weiterer Komponenten und konstruktiver
Vorkehrungen, für die der Errichter und Betreiber der Anlage Sorge zu tragen hat.
Wo bei Bruch oder Fehlfunktion der Wägezellen Menschen oder Sachen zu Schaden
kommen können, müssen vom Anwender geeignete zusätzliche Sicherheitsvorkehrungen
getroffen werden, die zumindest den Anforderungen der einschlägigen Unfallverhütungs
vorschriften genügen (z.B. automatische Notabschaltungen, Überlastsicherungen,
Fanglaschen oder ‐ketten oder andere Absturzsicherungen).
Die das Messsignal verarbeitende Elektronik ist so zu gestalten, dass bei Ausfall des
Messsignals keine Folgeschäden auftreten können.
Allgemeine Gefahren bei Nichtbeachten der Sicherheitshinweise
Die Wägezellen entsprechen dem Stand der Technik und sind betriebssicher. Von den
Aufnehmern können Gefahren ausgehen, wenn sie von ungeschultem Personal oder
unsachgemäß montiert, aufgestellt, eingesetzt und bedient werden. Jede Person, die mit
Aufstellung, Inbetriebnahme, Betrieb oder Reparatur einer Wägezelle beauftragt ist, muss
