SAFETY INSTRUCTIONS
1 SAFETY INSTRUCTIONS
Appropriate use
Transducers of the Z6R/Z6R-P 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, commissioning or operation of the trans
ducer must have read and understood the Operating Manual and in particular the techni
cal 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 concerned during use. The same applies to the
use of accessories.
The transducer is not intended for use as a safety component. Please also refer to the
section: "Additional safety precautions". Proper and safe operation requires proper trans
portation, correct storage, siting and mounting, and careful operation.
Operating conditions
SPlease observe the permissible maximum values stated in the specifications for:
-Limit load
-Limit lateral loading
-Breaking loads
-Temperature limits
-Limits of electrical loading capacity
SNote, that when several transducers are installed in a scale, there is not always an
even distribution 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 regulations, old transducers that can no longer be used must be dis
posed of separately and not with normal household garbage, see Chapter 6, Page 13.

Explosion protection version option
SComply with the relevant code of practice during installation.
SComply with the installation conditions cited in the Certificate of Conformity and/or
the Type Certificate.
Qualified personnel
Qualified persons means persons entrusted with the installation, fitting, commissioning
and operation of the product who possess the appropriate qualifications for their func
tion.
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 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 commissioning engineers or service engineers, they have successfully completed
the training to qualify them to repair the automation systems. They are also autho
rized to activate, ground and label circuits and equipment in accordance with safety
engineering standards.
Additional safety precautions
Additional safety precautions to meet the requirements of the relevant national and local
accident prevention regulations 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 mea
surement 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
measurement and automation technology so that residual risks are minimized. This par
ticularly 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 establish safe operating conditions.
General dangers of failing to follow the safety instructions
The transducer corresponds to the state of the art and is failsafe. The transducer may
give rise to residual dangers if it is inappropriately installed or operated.

CONDITIONS ON SITE
6
3 CONDITIONS ON SITE
Series Z6R/Z6R-P load cells are hermetically encapsulated and are therefore not at all
sensitive to the influence of moisture and humidity. Nevertheless, the load cells must be
protected against constant humidity and moisture.
Protection against corrosion
The load cell must be protected against chemicals that could attack the transducer body
steel, or the cable.
Notice
Acids and all substances that release ions also attack stainless steels and their welded
seams.
Should there be any corrosion, this could cause the transducer to fail. If this is the case,
you must provide appropriate means of protection.
Deposits
Dust, dirt and other foreign matter must not be allowed to accumulate sufficiently to
divert some of the measuring force onto the housing, thus invalidating the measured
value (force shunt).

4.1 Important precautions during installation
SHandle the transducer with care.
SWelding currents must not be allowed to flow over the transducer. If there is a risk
that this might happen, you must provide a suitable low-ohm connection to electrically
bypass the transducer. HBK, for example, provides the highly flexible EEK ground
cable, which can be screwed on above and below the transducer.
SMake sure that the transducer cannot be overloaded.
WARNING
There is a danger of the transducer breaking if it is overloaded. This can cause danger for
the operating personnel of the system in which the transducer is installed.
Implement appropriate safety measures to avoid overloads or to protect against the
resulting dangers.
Notice
Load cells are precision measuring elements and need to be handled carefully. Dropping or
knocking the transducer may cause permanent damage. Make sure that the transducer
cannot be overloaded, including while it is being mounted.
4.2 Mounting and load application
Attach the load cells at the mounting holes and apply load to the other end. The screws
and tightening torques to be used are given in the following table:
Maximum
capacities
Thread Min. property class Tightening torque 1))
20 … 200 kg M8 10.9 34 N⋅m
1) Recommendedvalue for the specified property class. Please comply with the screw manufacturer's
instructions with regard to screw dimensions.
Important
Load must not be applied to the side where the cable connection is located, as this would
cause a force shunt.

Z6R, Z6R-P
MECHANICAL INSTALLATION

The load must act as accurately as possible in the direction of measurement. Torsional
moments, eccentric loads and lateral or side forces cause measurement errors and can
permanently damage the load cell. Catch such interference effects, e.g. using lateral stay
bars or guide rollers, but ensure that these elements do not absorb any load or force
components in the direction of measurement (force shunt which will in turn lead to mea
surement errors).
To minimize error effects from load application, HBK offers different load application
elements, according to the mounting conditions:
SPendulum bearing ZPL (1-Z6/200kg/ZPL) (for nominal rated loads 20 kg … 200 kg)
SKnuckle eyes ZGWR (1-Z6/200kg/ZGWR) (for nominal rated loads 20 kg … 200 kg)

5.3 Cable assignment four-wire configuration
When transducers in a six-wire configuration are connected to amplifiers in a four-wire
configuration, the sense leads of the transducer must be connected to the corresponding
excitation voltage leads: Marking (+) with (+) and marking (-) with (-), see Fig. 5.1. This
measure also reduces the cable resistance of the excitation voltage leads. However,
there will be a voltage loss on the supply leads due to the cable resistance that is still
present and not compensated for by the six-wire configuration. A large part of this loss
can be eliminated by a calibration, however, the temperature-dependent part remains.

Z6R, Z6R-P
ELECTRICAL CONNECTION
Important
The TCsvalue given in the specifications for the transducer therefore does not apply for
the cable and transducer combination when connection is in a four-wire configuration,
where the cable percentage must be added.
The following deviations occur in the case of an uncut cable (3 m):
SSensitivity approx. -0.2%
STCSapprox. -0.01% per 10 K.
5.4 Shortening the cable
If the transducer is connected to an amplifier in a six-wire configuration, the transducer
cable can be shortened as required, without adversely affecting the measurement accu
racy.
5.5 Cable extension
Only use shielded, low-capacitance measurement cables for extending. Ensure that con
nection is perfect, with a low contact resistance. The cable of a six-wire transducer can
be extended with a cable of the same type.
Cable types recommended by HBK:
SKAB7.5/00‐2/2/2 (by the meter, Order No. 4‐3301.0071 for gray or 4‐3301.0082 for
blue version)
SCABA1 (cable roll, Order No. CABA1/20 = 20 m or CABA1/100 = 100m long)
5.6 Parallel connection
Only load cells with an aligned output (nominal (rated) sensitivity and output resistance)
are suitable for parallel connection. The load cells can be wired in parallel by joining the
load cell cable core ends of the same color. For this purpose, type VKK junction boxes,
also for explosion protection, are available in the HBK product line. The output signal is
then the average of the individual output signals.
Important
Overloading in an individual load cell cannot then be detected from the output signal after
load cells have been connected in parallel.
5.7 EMC protection
Electrical and magnetic fields often induce interference voltages in the measuring circuit.
To ensure reliable measurement, however, the transducer must be able to transmit signal
differences of a few μV to the analysis unit without interference.

ELECTRICAL CONNECTION

Planning the shielding design
Due to the numerous application options and differing local constraints, we can only
provide you with general information on correct connection. The shielding design suitable
for your application must be planned locally by an appropriate specialist.
HBM load cells with shielded, round cables are EMC-tested in accordance with the
EU Directive and bear the CE mark. Voltage surges as per EN 61000-4-5 can give rise to
deviations from the load cell’s specified accuracy. These surges in plants are caused by
lightning strikes or switching operations in power circuits, for example, and disappear
again when interference is no longer active. This is particularly evident with cables over
30 m long or if the equipment is used outdoors. Customers should take additional pre
cautions in these cases.
Please note:
SConnect the connecting cable shield all over the surface of the shielding electronics
housing. When using several load cells, connect the shields all over the surface of the
junction box (combination of transducer signals, e.g. type VKK2 from HBM). From
there, connect the measurement cable for the electronics over the surface of the
junction box and the shielding electronics housing.
SThe shield of the connecting cable must not be used for discharging potential
differences within the system. You must therefore lay sufficiently dimensioned
potential equalization lines to compensate for possible potential differences.
SUse shielded low-capacitance measurement cables only (HBM cables fulfill these
conditions).
SDo not route measurement cables parallel to electric cables, especially power lines
and control circuits. If this is not possible, protect the measurement cable, for
example with steel conduits.
SAvoid stray fields from transformers, motors and contact switches.
Important
Potential equalization is specified for applications in potentially explosive atmospheres.
