Safety instructions

The supply connection, as well as the signal and sense leads, must be

installed in such a way that electromagnetic interference does not adversely

affect device functionality (HBM recommendation: ”Greenline shielding

design”, downloadable from the Internet at http://www.hbm.com/Greenline).

Automation equipment and devices must be covered over in such a way that

adequate protection or locking against unintentional actuation is provided

(such as access checks, password protection, etc.).

When devices are working in a network, these networks must be designed in

such a way that malfunctions in individual nodes can be detected and shut

down.

Safety precautions must be taken both in terms of hardware and software, so

that a line break or other interruptions to signal transmission, such as via the

bus interfaces, do not cause undefined states or loss of data in the

automation device.

Appropriate use

The CFT piezoelectric force transducer is intended for compressive force

measurements in test benches, press‐fit processes, test and inspection

equipment and presses. Use for any additional purpose shall be deemed to

be not appropriate.

In the interests of safety, the transducer should only be operated as described

in the Mounting Instructions. 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 force transducer is not a safety element within the meaning of appropriate

use. For safe and trouble‐free operation, this transducer must not only be

correctly transported, stored, sited and mounted but must also be carefully

operated and maintained.

Each time, before starting up the equipment, you must first run a project

planning and risk analysis that takes into account all the safety aspects of

automation technology. This particularly concerns personal and machine

protection.

Additional safety precautions must be taken in plants where malfunctions

could cause major damage, loss of data or even personal injury. In the event

of a fault, these precautions establish safe operating conditions.

This can be done, for example, by mechanical interlocking, error signaling,

limit value switches, etc.

General dangers of failing to follow the safety instructions

The CFT piezoelectric force transducer is state of the art and reliable.

The transducer complies with the state of the art and is safe to operate. If the

transducer is used and operated inappropriately by untrained personnel,

residual dangers may arise.

Anyone responsible for installing, starting up, maintaining or repairing the

transducer needs to have read and understood the operating manual and in

particular the safety instructions.

Remaining dangers

The scope of supply and performance of the force transducer covers only a

small area of force measurement technology. In addition, equipment planners,

installers and operators should plan, implement and respond to the safety en

gineering considerations of force measurement technology in such a way as

to minimize remaining dangers. Prevailing regulations must be complied with

at all times. There must be reference to the remaining dangers associated

with force measurement technology.

Remaining dangers are indicated in these Mounting Instructions by the

following symbols:

Symbol: WARNING

Meaning: Dangerous situation

Warns of a potentially dangerous situation in which failure to comply with

safety requirements can result in death or serious physical injury.

Symbol: ATTENTION

Meaning: Possibly dangerous situation

Warns of a potentially dangerous situation in which failure to comply with

safety requirements could result in damage to property or some form of

physical injury.

Symbol: NOTE

Means that important information about the product or its handling is being

given.

CFT

A2529-2.0 en/de/frHBM

Symbol:

Meaning: CE mark

The CE mark enables the manufacturer to guarantee that the product

complies with the requirements of the relevant EC directives (the Declaration

of Conformity can be found at http://www.hbm.com/HBMdoc).

Symbol:

Meaning: Statutory marking requirements for waste disposal

National and local regulations regarding the protection of the environment and

recycling of raw materials require old equipment to be separated from regular

domestic waste for disposal.

For more detailed information on disposal, please contact the local authorities

or the dealer from whom you purchased the product.

Conversions and modifications

The force 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.

The product is delivered from the factory with a fixed hardware and software

configuration. Changes can only be made within the possibilities documented

in the manuals.

Qualified personnel

The transducer may be used by qualified personnel only; the specifications

and the special safety regulationsneed to be followed in all cases.

This means people who meet at least one of the three following requirements:

-Knowledge of the safety concepts of automation technology is a

requirement and as project personnel, you must be familiar with these

concepts.

-As automation plant operating personnel, you have been instructed how to

handle the machinery and are familiar with the operation of the equipment

and technologies described in this documentation.

CFT

A2529-2.0 en/de/fr HBM

-As commissioning engineers or service engineers, you have successfully

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

You are also authorized to activate, to ground and label circuits and

equipment in accordance with safety engineering standards.

It is also essential to comply with the appropriate legal and safety regulations

for the application concerned during use. The same applies to the use of ac

cessories.

Qualified personnel means personel familiar with the installation, fitting,

start-up and operation of the product, and trained according to their job.

Conditions at the place of installation

Protect the force transducer from moisture and dampness or weather

conditions such as rain, snow, ice and salt water.

To comply with EN 61326-1, para. 3.6 , the connecting leads of the CFT force

measurement chain must not be more than 30 m in length (if run in a building)

and must not exit the building.

Maintenance

The CFT piezoelectric force transducer is maintenance free.

Accident prevention

The prevailing accident prevention regulations must be taken into account,

even though the nominal (rated) force values in the destructive range are well

in excess of the full scale value.

2 Application instructions

Piezoelectric force transducers of the CFT type series are suitable for

measuring compressive forces. Because they provide highly accurate

dynamic and quasi‐static force measurements, they must be handled very

carefully. Particular care must be taken when transporting and installing the

devices. Dropping or knocking the transducers may cause permanent

damage.

The transducers are extremely rigid and have a high natural frequency.

The specifications list the permissible limits for mechanical, thermal and

electrical stress. It is essential that these are taken into account when

planning the measuring set‐up, during installation and ultimately, during

operation.

3 Conditions on site

ATTENTION

The insulation resistance is crucial for piezoelectric transducers; it

should be greater than 1013 ohms. To obtain this value , all the

plug connections have to be kept thoroughly clean. A positive or

negative signal drift of the nominal (rated) output signal indicates

insufficient insulation resistance. The plug connection contacts

should then be cleaned with a clean, lint‐free cloth and a cleaning

agent (petroleum ether, isopropanol).

ATTENTION

Protect the transducer plug against pollution and under no

circumstances touch the connectors (plug face) with your

hand. The supplied cover should always be in place when the

connection is not in use.

Once mounted, the connection cable should remain connected to the

transducer, if possible.

3.1 Ambient temperature

The temperature has little effect on the output signal. To obtain optimum mea

surement results, the nominal (rated) temperature range must be observed.

Temperature‐related measurement errors are caused by heating on one side

(e.g. radiant heat) or by cooling. A radiation shield and all‐round thermal in

sulation produce noticeable improvements, but must not be allowed to form a

force shunt.
