1 Safety instructions
Appropriate use
Transducers of the Z6R... 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 section: "Additional
safety precautions". 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
Z6R… A4514-1.0 HBM: public 5
- 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 regula
tions, old transducers that can no longer be used
must be disposed of separately and not with normal
household garbage, see Chapter 6, Page 18.
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 function.
This includes people who meet at least one of the three
following requirements:

Safety instructions
6A4514-1.0 HBM: public Z6R…
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
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.
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.

Conditions on site
Z6R… A4514-1.0 HBM: public 9
3 Conditions on site
Series Z6R... load cells are hermetically encapsulated
and are therefore not at all sensitive to the influence of
moisture and humidity. The transducers achieve protec
tion class IP68 (test conditions: 1,000 hours under 2 m
water column) as per DIN EN60529. 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.
Explosion protection version option
The ambient temperature range specified on the trans
ducer must not be exceeded.
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).

Mechanical installation

4 Mechanical installation
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. HBM, 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 over
loaded. This can cause danger for the operating person
nel of the system in which the transducer is installed.
Implement appropriate safety measures to avoid over
loads or to protect against the resulting dangers.
Notice
Load cells are precision measuring elements and need to
be handled carefully. Dropping or knocking the trans
ducer may cause permanent damage. Make sure that the
transducer cannot be overloaded, including while it is
being mounted.

Mechanical installation
Z6R… A4514-1.0 HBM: public 11
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.
The load must act as accurately as possible in the direc
tion of measurement. Torsional moments, eccentric loads
and lateral or side forces cause measurement errors and
can permanently damage the load cell. Catch such inter
ference 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 measure
ment (force shunt which will in turn lead to measurement
errors).
To minimize error effects from load application, HBM
offers different load application elements, according to
the mounting conditions:
SPendulum bearing ZPL (Z6/200kg/ZPL) (for nominal
rated loads 20 kg … 200 kg)
SKnuckle eyes ZGWR (Z6/200kg/ZGWR) (for nominal
rated loads 20 kg … 200 kg)

Fig. 5.1 Pin Assignment
With this connector pin assignment, the output voltage at
the measuring amplifier is positive when the transducer is
loaded.

Electrical connection
14 A4514-1.0 HBM: public Z6R…
5.2 Connection in four-wire configuration
When transducers in a six-wire configuration are con
nected 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 volt
age 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 configu
ration. A large part of this loss can be eliminated by a
calibration, however, the temperature-dependent part
remains.
Important
The TCsvalue given in the specifications for the trans
ducer therefore does not apply for the cable and trans
ducer combination when connection is in a four-wire con
figuration, 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.
5.3 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
accuracy.

Electrical connection
Z6R… A4514-1.0 HBM: public 15
5.4 Cable extension
Only use shielded, low-capacitance measurement cables
for extending. Ensure that connection 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 HBM:
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)
5.5 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.
The type VKK terminal boxes or the VKK2R-8 Ex version
for potentially explosive areas are available in the HBM
product line for this purpose. 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.

Electrical connection
16 A4514-1.0 HBM: public Z6R…
5.6 EMC protection
Background information
Electrical and magnetic fields often induce interference
voltages in the measuring circuit. For reliable measure
ments, signal differences of less than 1μV must be trans
mitted without interference from the transducer to the
evaluation electronics.
Planning of the shielding concept
Due to the numerous application options and the different
local constraints, we can only provide you with informa
tion for correct connection. The shielding concept suit
able for your application must be planned locally by an
appropriate specialist.
The load cells with shielded, round cables are EMC-
tested in accordance with EC directives and identified by
CE certification.
Points to be observed
SUse shielded, low-capacitance measurement cables
only (HBM cables fulfill both conditions).
SDo not route the measurement cables parallel to
power lines and control circuits. If this is not possible,
protect the measurement cable with e.g. steel con
duit.
SAvoid stray fields from transformers, motors and con
tact switches.
SConnect the shield of the connection cable exten
sively on the shielding electronics housing. When
using several load cells, connect the shield exten
sively to the junction box (combination of transducer
signals, e.g. type VKK1R-4 from HBM). From there,

Electrical connection
Z6R… A4514-1.0 HBM: public 17
connect the measurement cable for the electronics
extensively to the junction box and extensively to the
shielding electronics housing.
SThe shield of the connection 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.
Important
Potential equalization is specified for applications in
potentially explosive atmospheres.

Waste disposal and environmental protection
18 A4514-1.0 HBM: public Z6R…
6 Waste disposal and environmental protection
The correct disposal of old equipment prevents ecologi
cal damage and health hazards.
As waste disposal regulations may differ from country to
country, we ask that you contact your supplier to deter
mine what type of disposal or recycling is legally applica
ble in your country.
Packaging
The original HBM packaging is made from recyclable
material and can be sent for recycling. Store the packag
ing for at least the duration of the warranty.
For ecological reasons, empty packaging should not be
returned to us.
