1 Safety instructions
Appropriate use
Transducers of the Z6... 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 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 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 transportation, correct storage, siting and mounting, and care
ful operation.
Operating conditions
Please observe the permissible maximum values stated in the specifica
tions for:
- Limit load
- Limit load at max. eccentricity
- Limit lateral loading
- Breaking loads
- Temperature limits
- Limits of electrical loading capacity
Note, that when several transducers are installed in a scale, there is not
always an even distribution of load on the individual transducers.
The 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.

Safety instructions
Z6… A01027_04_Y00_02 HBM: public 5
The transducer must not be modified from the design or safety engineering
point of view except with our express agreement.
The transducer is maintenance-free.
In accordance with national and local environmental protection and material
recovery and recycling regulations, old transducers that can no longer be
used must be disposed of separately and not with normal household
garbage, see Chapter 6, Page 14.
Explosion protection version option
Comply with the relevant code of practice during installation.
Comply 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, com
missioning and operation of the product who possess the appropriate qualifica
tions for their function.
This includes people who meet at least one of the three following requirements:
Knowledge of the safety concepts of measurement and automation technol
ogy is a requirement and as project personnel, they must be familiar with
these concepts.
As 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.
As commissioning engineers or service engineers, they have successfully
completed the training to qualify them to repair the automation systems.
They are also authorized to activate, ground and label circuits and equip
ment 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 mal
functions could cause major damage, loss of data or even personal injury.

Safety instructions
6A01027_04_Y00_02 HBM: public Z6…
The scope of supply and performance of the transducer covers only a small
area of measurement technology. Before starting up the transducer in a sys
tem, 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 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 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 trans
ducer may give rise to residual dangers if it is inappropriately installed or oper
ated.

Conditions on site
8A01027_04_Y00_02 HBM: public Z6…
3 Conditions on site
Series Z6... load cells are hermetically encapsulated and are therefore not at
all sensitive to the influence of moisture and humidity. The transducers achieve
protection class IP68 (test conditions: 100 hours under 1 m water column) as
per DIN EN60529. Nevertheless, the load cells must be protected against con
stant humidity and moisture.
Protection against corrosion
The load cell must be protected against chemicals that could attack the trans
ducer 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 transducer must not be
exceeded.
Deposits
Dust, dirt and other foreign matter must not be allowed to accumulate suffi
ciently to divert some of the measuring force onto the housing, thus invalidating
the measured value (force shunt).

Mechanical installation
Z6… A01027_04_Y00_02 HBM: public 9
4 Mechanical installation
4.1 Important precautions during installation
Handle the transducer with care.
The bellows material is very thin and can therefore be easily damaged.
Welding 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 connec
tion 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.
Make 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:

Thread Min. property class Tightening torque 1)
5 - 200 kg M8 10.9 34 N⋅m
500 kg M10 12.9 76 N⋅m
1 t M12 10.9 115 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 direction of measurement.
Torsional moments, eccentric loads and lateral or side forces cause measure
ment errors and can permanently damage the load cell. Catch such interfer
ence 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 mea
surement (force shunt which will in turn lead to measurement errors).
To minimize error effects from load application, HBM offers different load appli
cation elements, according to the mounting conditions:
Pendulum bearing ZPL
Knuckle eyes ZGWR
Force feedback ZRR (for maximum capacities 5kg …200kg)
Rubber-metal bearing ZEL
Cone/conical pan ZK
Oscillating loading foot PCX (for maximum capacities 5kg …500kg)
Oscillating loading foot ZFP (for maximum capacities 5kg …200kg)
Oscillating loading foot ZKP (for maximum capacities 5kg …200kg)
Mounting base / mounting kit ZPU Z6/ZPU/200KG (for maximum capacities
5kg …200kg)
Z6/ZPU/500KG (for maximum capacity 500 kg)

5 Electrical connection
The following can be connected for measurement signal conditioning:
carrier-frequency amplifiers
DC amplifiers
designed for strain gauge measurement systems.
The load cells are delivered with a six-wire configuration.

Fig. 5.1 Pin Assignment
With this connector pin assignment, the output voltage at the measuring ampli
fier is positive when the transducer is loaded.
5.2 Connection in 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

Electrical connection
12 A01027_04_Y00_02 HBM: public Z6…
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.
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):
Sensitivity approx. -0.2%
TCSapprox. -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.
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:
KAB7.5/00‐2/2/2 (by the meter, Order No. 4‐3301.0071 for gray or
4‐3301.0082 for blue version)
CABA1 (cable roll, Order No. CABA1/20 = 20 m or CABA1/100 = 100m
long)

Electrical connection
Z6… A01027_04_Y00_02 HBM: public 13
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.
5.6 EMC protection
Background information
Electrical and magnetic fields often induce interference voltages in the measur
ing circuit. For reliable measurements, signal differences of less than 1μV must
be transmitted without interference from the transducer to the evaluation elec
tronics.
Planning of the shielding concept
Due to the numerous application options and the different local constraints, we
can only provide you with information for correct connection. The shielding con
cept suitable 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
Use shielded, low-capacitance measurement cables only (HBM cables fulfill
both conditions).

Waste disposal and environmental protection
14 A01027_04_Y00_02 HBM: public Z6…
Do 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 conduit.
Avoid stray fields from transformers, motors and contact switches.
Connect the shield of the connection cable extensively on the shielding
electronics housing. When using several load cells, connect the shield
extensively to the junction box (combination of transducer signals, e.g. type
VKK2 from HBM). From there, connect the measurement cable for the elec
tronics extensively to the junction box and extensively to the shielding elec
tronics housing.
The shield of the connection cable must not be used for discharging poten
tial differences within the system. You must therefore lay sufficiently dimen
sioned potential equalization lines to compensate for possible potential dif
ferences.
Important
Potential equalization is specified for applications in potentially explosive
atmospheres.
6 Waste disposal and environmental protection
The correct disposal of old equipment prevents ecological damage and health
hazards.
As waste disposal regulations may differ from country to country, we ask that
you contact your supplier to determine what type of disposal or recycling is
legally applicable in your country.
Packaging
The original HBM packaging is made from recyclable material and can be sent
for recycling. Store the packaging for at least the duration of the warranty.
For ecological reasons, empty packaging should not be returned to us.
