1 Safety instructions

Appropriate use

Transducers of the FIT7A type series are designed solely

for technical weighing applications within the application

limits detailed in the specifications. Any other use is not

appropriate.

Any person instructed to carry out installation, commis

sioning or operation of the transducer must have read

and understood the Operating Manual and in particular

the technical safety instructions.

In the interests of safety, the transducer should only be

operated by qualified personnel and as described in the

Operating Manual. It is also essential to comply with the

legal and safety requirements for the application con

cerned during use. The same applies to the use of

accessories.

The transducer is not intended for use as a safety com

ponent. Please also refer to the "Additional safety pre

cautions" section. Proper and safe operation requires

proper transportation, correct storage, siting and mount

ing, and careful operation.

Operating conditions

SPlease observe the permissible maximum values

stated in the specifications for:

- Limit load

- Limit load at max. eccentricity

- Limit lateral loading

- Breaking loads

- Temperature limits

Safety instructions

FIT®7A A3924-1.1 HBM: public 5

- Limits of electrical load-carrying capacity

SPlease note that when several transducers are

installed in a scale, there is not always an even distri

bution of load on the individual transducers.

SThe transducers can be used as machine elements.

When used in this manner, it must be noted that, to

favor greater sensitivity, the transducer is not

designed with the safety factors usual in mechanical

engineering.

SThe transducer must not be modified from the design

or safety engineering point of view except with our

express agreement.

SThe transducer is maintenance-free.

SIn accordance with national and local environmental

protection and material recovery and recycling regula

tions, old transducers that can no longer be used

must be disposed of separately and not with normal

household garbage, see Chapter 9, Page 25.

Qualified personnel

Qualified persons means persons entrusted with the

installation, fitting, commissioning and operation of the

product who possess the appropriate qualifications for

their function.

This includes people who meet at least one of the three

following requirements:

SKnowledge of the safety concepts of measurement

and automation technology is a requirement and as

project personnel, they must be familiar with these

concepts.

SAs measurement or automation plant operating per

sonnel, they have been instructed how to handle the

Safety instructions

6A3924-1.1 HBM: public FIT®7A

machinery. They are familiar with the operation of the

equipment and technologies described in this docu

mentation.

SAs commissioning engineers or service engineers,

they have successfully completed the training to qual

ify them to repair the automation systems. They are

also authorized to activate, ground and label circuits

and equipment in accordance with safety engineering

standards.

Working safely

SThe device must not be directly connected to the

power supply system. The supply voltage must be

between 10 and 30 VDC.

SError messages should only be acknowledged once

the cause of the error is removed and no further dan

ger exists.

SMaintenance and repair work on an open device with

the power on may only be carried out by trained per

sonnel who are aware of the dangers involved.

SAutomation equipment and devices must be designed

in such a way that adequate protection or locking

against unintentional actuation is provided (e.g.

access checks, password protection, etc.).

SFor those devices operating in networks, safety pre

cautions must be taken both in terms of hardware and

software, so that a line break or other interruptions to

signal transmission do not cause undefined states or

loss of data in the automation device.

SAfter making settings and carrying out activities that

are password-protected, ensure that any controls that

may be connected remain in a safe condition until the

switching performance of the device has been tested.

Additional safety precautions

Additional safety precautions to meet the requirements of

the relevant national and local accident prevention regu

lations must be taken in plants where malfunctions could

cause major damage, loss of data or even personal

injury.

The scope of supply and performance of the transducer

covers only a small area of measurement technology.

Before starting up the transducer in a system, a project

planning and risk analysis must first be implemented,

taking into account all the safety aspects of measure

ment and automation technology so that residual risks

are minimized. This particularly concerns personal and

machine protection. The transducers function passively

and cannot implement any (safety-relevant) cutoffs. In

the event of a fault, the relevant precautions must estab

lish safe operating conditions.

General dangers of failing to follow the safety

instructions

The transducer corresponds to the state of the art and is

reliable. The transducer may give rise to residual dangers

if it is inappropriately installed or operated.

Markings used

8A3924-1.1 HBM: public FIT®7A

2 Markings used

2.1 Symbols on the device

Statutory waste disposal mark

In accordance with national and local environmental pro

tection and material recovery and recycling regulations,

old devices that can no longer be used must be disposed

of separately and not with normal household garbage.

Also see Section 9 on Page 25.

CE mark

The CE mark enables the manufacturer to guarantee that

the product complies with the requirements of the rele

vant EC directives (the Declaration of Conformity can be

found on the HBM website (www.hbm.com) under

HBMdoc).

2.2 The marking 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 Significance

WARNING This marking warns of a potentially dangerous situ

ation in which failure to comply with 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 safety requirements can

lead to damage to property.
