3.8 Signal jump electronics
Compliance with functional safety
An external safety control system independent of the force transducer must monitor the
safe functioning of the force transducer.The functional test with a signal jump of
4 mA / 2 V is executed at an interval of 24 hours.The safety control system activates the
relay A, thus changing the output signal of the force transducer in a defined manner.
If the expected change in the output signal occurs, it can be assumed that the entire
signal path from the Wheatstone bridge via the amplifier through to the output is
functioning correctly. If this does not occur, then it can be concluded that there is a error
in the signal path.
Moreover, the measuring signal should be checked by the safety control for the min.
(A) and max. (B) signal value to ensure that any cable break or short-circuit that has
occurred is detected.The default setting of the force transducer with current output
4 ... 20 mA for overload detection is, for example:
With a fixed signal jump of, for example, 4 mA, the test cycle can then be triggered, in any
operating state, by activating the test relay.The upper measuring range limit of 20 mA will
never be reached and thus the checking of the signal jump is enabled.

3.9 RoHS evaluation
The tension/compression force transducers are intended for use in stationary large
tools, large systems and moving machines.The tension/compression force transducers
are therefore excluded from the scope of the EU Directive 2011/65/EU (RoHS); see
2011/65/EU, Article 2 (4) d), e) and g) and thus also to the Restriction of the Use of
Certain Hazardous Substances in Electrical and Electronic Equipment Regulations

4. Transport, packaging and storage
4. Transport, packaging and storage
4.1 Transport
Check the tension/compression force transducer for any damage that may have been
caused by transport. Obvious damage must be reported immediately.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to property can occur.

When unloading packed goods upon delivery as well as during
internal transport, proceed carefully and observe the symbols on the
packaging.

With internal transport, observe the instructions in chapter 4.2
“Packaging and storage”.
As precision measuring instruments, the transducers require careful handling during
transport and mounting. Load impacts during transport (e.g. hitting a hard surface) can
lead to permanent damage, resulting in measuring errors in the subsequent measuring
operation.
4.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change
in installation site, sending for repair).
The measuring spring is made completely of stainless steel.The version of the
accessory cables has an ingress protection of IP67. During storage the protection cap
must always be on the electrical connection to avoid entry of moisture and dirt.
Permissible conditions at the place of storage:

Storage temperature: -40 ... +85 °C [-40 ... +185 °F]

Humidity: 35 ... 85 % relative humidity (non-condensing)
Avoid exposure to the following factors:

Mechanical vibration, mechanical shock (putting it down hard)

Dust, dirt, and other objects may not be deposited in such a way that they form a
force shunt with the measuring spring, since this will falsify the measuring signal.

5.1 Precautions before mounting

Tension/compression force transducers are sensitive measuring instruments and
must be handled with appropriate care.

Before installing the tension/compression force transducer, check whether the
threaded bores of the installation position have been executed dimensionally
accurately, thus guaranteeing problem-free mechanical installation of the tension/
compression force transducer.

Before installation, make sure that any drilling chips have been removed from the
threaded bores.
5.2 Mounting instructions
CAUTION!
Damage to the instrument through improper installation

With the installation of the force transducer, the installation position and
the load direction must be considered.

Torsional and shear forces must be avoided. Transverse loads and
lateral forces also include the corresponding components of the
measurands that are introduced slanted.

Torsional moments, eccentric loads and transverse loads or lateral
forces cause measuring errors and may permanently damage the
tension/compression force transducer.

The supplied counter nuts must never rest on the deformation element.
A gap of at least 0.5 mm [0.02 in] must be provided.

A possible counterpart may also not be screwed in as far as it will go in
the internal thread.

The installation of the tension/compression force transducer must not
be made with any violent force.

During installation of the tension/compression force transducer,
the output signal (force value) must always be monitored to avoid
mechanical overload.

When subjected to loads in other instruments, other than those
planned in the application, a change in the zero signal may result in
permanent damage.

Do not use the tension/compression force transducer as a climbing aid.

If high shear forces or lateral forces are to be expected, the use of
swivel heads is recommended (see chapter 10 “Accessories”).


Connect the cable shield with the case of the tension/compression force transducer.
In the cables of the accessories, the cable shield is connected by means of the
knurled nut, thus connecting it to the case of the tension/compression force
transducer (for cables, see chapter 10 “Accessories”).

Do not install measuring cables in parallel to 3-phase-current cables and control
cables.

Avoid stray fields of transformers, motors and contactors.

Transducers, amplifiers and processing or display units must not be grounded
several times. Connect all instruments to the same protective conductor.
The pin assignment of the connector or of the cable can be found on the product label.
When using extensions, only shielded and low-capacitance cables should be used.The
permitted maximum and minimum lengths of cable are defined in ISO 11898-2. Care
should be taken about the shielding.
