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.

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.
