1 Safety instructions

Intended use

Load cells of the PWS type series are designed for technical weighing applica

tions within the load limits detailed in the specifications. Any other use is not

the designated 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 section: “Additional safety precautions". Proper and safe operation of the

load cells requires proper transportation, correct storage, siting and mounting,

and careful operation.

Load-carrying capacity limits

The data in the technical data sheet must be complied with when using the

load cells. In particular, the respective maximum loads specified must never be

exceeded. The following limits set out in the specifications must not be

exceeded, e.g.:

SLimit load

SLimit load at max. eccentricity

SLimit lateral loading

SBreaking loads

STemperature limits

SLimits of electrical loading capacity

Note that, when several load cells are installed in a scale, there is not always

an even distribution of load on the individual load cells.

Safety instructions

4A05750_02_XA0_00 HBM: public PWS

Use as a machine element

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 here to

the section “Loading capacity limits" and to the specifications.

Accident prevention

The prevailing accident prevention regulations must be taken into account,

even though the maximum capacity values in the destructive range are 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 layout of the electronics conditioning the measurement signal should be

such that measurement signal failure does not cause damage.

General dangers of failing to follow the safety instructions

Load cells are state‐of‐the‐art and reliable. Transducers can give rise to resid

ual dangers if they are incorrectly operated or inappropriately mounted,

installed and operated 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. The

load cells can be damaged or destroyed by non‐designated use of the load

cells or by non‐compliance with the mounting and operating instructions, these

safety instructions or any other applicable safety regulations (BG safety and

accident prevention regulations) when using the load cells. Load cells can

break, particularly in the case of overloading. The breakage of a load cell can

Safety instructions

PWS A05750_02_XA0_00 HBM: public 5

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 instructions 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 gauge

sensors presuppose the use of electronic signal processing. In addition, equip

ment 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.

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 Meaning

WARNING This marking warns of a potentially dangerous situa

tion in which failure to comply with the safety require

ments can result in death or serious physical injury.

Note This marking draws your attention to a situation in

which failure to comply with the safety requirements

can result in damage to property.

Emphasis

See …

Italics are used to emphasize and highlight text and

identify references to sections, diagrams, or external

documents and files.

Conversions and modifications

The transducer 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.

Safety instructions

6A05750_02_XA0_00 HBM: public PWS

Maintenance

The load cells of the PWS series are maintenance free.

Waste disposal

In accordance with national and local environmental protection and material

recovery and recycling regulations, old transducers that can no longer be used

must be disposed of separately and not with normal household garbage.

If you need more information about disposal, please contact your local authori

ties or the dealer from whom you purchased the product.

Qualified personnel

Qualified personnel means persons entrusted with siting, mounting, starting up

and operating the product who possess the appropriate qualifications for their

function.

This includes people who meet at least one of these three requirements:

SThey know about the safety concepts of automation and as project person

nel, are familiar with these concepts

SAs automation plant operating personnel, they have been instructed how to

handle the machinery. They are familiar with the operation of the equipment

and technologies described in this documentation.

SAs system startup engineers or service engineers, they have successfully

completed the training to qualify them to repair the automation systems.

They are also authorized to activate, ground and label circuits and equip

ment in accordance with safety engineering standards.

It is also essential to comply with the legal and safety requirements for the

application concerned during use. The same applies to the use of accessories.

The load cell may only be installed by qualified personnel, strictly in accor

dance with the specifications and with the safety requirements and regulations.

3 General application instructions

Load cells are suitable for measuring compressive forces. Because they pro

vide highly accurate static and dynamic force measurements, they must be

handled very carefully. Particular care must be taken when transporting and

installing the devices. Dropping and knocking the transducer may cause per

manent damage.

For information on the permissible limits for mechanical, thermal and electrical

stress, please see PWS data sheet.
