SAFETY INSTRUCTIONS
1 SAFETY INSTRUCTIONS
Intended use
Load cells of the PW15PH…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 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 and operated inappropriately or by untrained person
nel. 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.

SAFETY INSTRUCTIONS
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.
Qualified personnel
Qualified personnel means persons entrusted with installing, mounting, starting up and
operating the product, who possess the appropriate qualifications for their function.
This includes people who meet at least one of the three following criteria:
1. Knowledge of the safety concepts of automation technology is a requirement and as
project personnel, you must be familiar with these concepts.
2. As automation plant operating personnel, you have been instructed how to handle the
machinery. You are familiar with the operation of the equipment and technologies
described in this documentation.
3. As commissioning engineers or service engineers, you have successfully completed
the training to repair the automation systems. You are also authorized to operate,
ground and mark circuits and equipment in accordance with safety engineering stan
dards.

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
Attach the load cells at the mounting holes and apply the load to the other end. The table
below contains the required screws and tightening torques:
Maximum capacities Thread Min. property class Tightening torque1)

provided by the screw manufacturer.
Important
Load must not be applied to the side where the cable connection is located, as this would
cause a force shunt.
