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)
SRubber-metal bearing ZEL (1-Z6/200kg/ZEL) (for nominal rated loads 20 kg … 200 kg)
SCone/conical pan ZK (1-Z6/200kg/ZK) (for nominal rated loads 20 kg … 200 kg)
SOscillating loading foot PCX (1-Z6/PCX/500kgSet) (for nominal rated loads
20 kg … 200 kg)
SOscillating loading foot ZKP (1-Z6/ZKP/200kg) (for nominal rated loads
20 kg … 200 kg)
SMounting plate / Mounting set ZPU (1-Z6/ZPU/200kg) (for nominal rated loads
