4 ASSEMBLY INSTRUCTIONS
 Checking after completed assembly
When assembling the HEUFT encoder the following conditions must be fulfilled in order that it can be
assembled with other parts properly and without any limitation of the safety and the health of persons to a
completed machine:

• The HEUFT encoder may be put into operation as a partly completed machine only if it has been
determined that the machine into which the encoder has been assembled corresponds to the
Machinery Directive.

• The HEUFT encoder has been completely assembled.

• The HEUFT encoder has been correctly connected to the terminals (24 V DC (PELV)) provided on the
standard device (refer to the wiring diagram of the standard device).

• Assembly of the encoder support and of the protective hood has been carried out in such a way that no
interventions on moving parts of the encoder (= encoder coupling) are possible.

• The cables have been laid in such a way that there is no risk of stumbling or falling.

• The bolts for fastening to the conveyor side frame are not too long, i.e. the return conveyor cannot hit
against the bolts.

 EC declaration of incorporation (template)
The template for the EC declaration of incorporation is in the folder of the complete documentation in which
these assembly instructions can also be found.

Intended use (purpose)

The encoder is used for recording conveyor movements.

The encoder is not suitable for application in potentially explosive areas.

The encoder has been designed exclusively for industrial and commercial purposes.

The encoder must not be used for other purposes than those for which it has been designed.

The operator is responsible for the proper use of the encoder.

HEUFT encoder (short variant) HEUFT encoder

Operating principle
Per rotation of the encoder shaft the encoder transmits a particular number of pulses to the standard device.
HBDR119TM ENG MA Taktgeber

The encoder shaft is connected to the drive shaft of the conveyor chain. Each encoder pulse thus
corresponds to a distance the conveyor has moved. Therefore it is possible for the standard device to
determine the container movement on the conveyor.

ASSEMBLY INSTRUCTIONS 7
Technical specifications
Encoder output: Open collector or HEUFT ISI
Pulses per revolution: 800/5,000*
Required space: approximately 100 mm x 210 mm (width x depth)
Maximum encoder frequency: 10 kHz
Weight: 3.2 kg
* The number of pulses depends on the application.

Electrical system
The electric power supply is carried out via the HEUFT standard device.

Supply voltage: 24 V DC (PELV)

Degree of protection
The encoder belongs to degree of protection IP54 according to the specification DIN EN 60529 / EN 60529 /
IEC 60529.

Ambient conditions
The encoder has been designed for use in closed rooms under the following conditions:

Air temperature: 5° to 40° centigrade

Air humidity: 30% to 95% relative air humidity, non-condensing

The limit values are in accordance with the details as per DIN EN 60204-1 / EN 60204-1 / IEC 60204-1.
Sudden fluctuations in temperature should be avoided because they could result in condensation forming.
Strong sunlight should be avoided because it can heat up the casings.

Noise emission
The A-weighted emission sound level of the encoder is lower than 70 dB(A).

EMC protection (electromagnetic compatibility)

The encoder was manufactured according to the valid EMC standards and is a class A encoder. It fulfils the
limit values for industrial environments and is not designed for domestic use. Improper use or modifications to
the encoder may cause malfunctions.

Transport and storage

11.00.007

Transport and store the encoder only in its original packaging. The packaging may only be opened by people
authorised by the HEUFT SYSTEMTECHNIK company. The entire packaging material is reusable and the
customer should arrange for it to be returned to the material flow or collected for recycling.
HBDR119TM ENG MA Taktgeber

Temperature range for storage: -20 °C to +60 °C

8 ASSEMBLY INSTRUCTIONS
 Assembly
The encoder support makes it possible to assemble the encoder to a HEUFT conveyor system or to a
conveyor system available on site.

The assembly instructions describe the attachment of the encoder to a HEUFT conveyor system. Information
is given then to other assembly options. This information should help when assembling the encoder to a
conveyor system available on site.

Assembly of the encoder is carried out by HEUFT service personnel or by qualified

personnel who have been trained by the HEUFT company.

Before carrying out any assembly work stop the conveyor and secure it to prevent it
being inadvertently switched on again!

Working at, above and below the conveyor belts is only permitted when the conveyor
system (and thus the conveyor belts) has been switched off and secured against
being inadvertently switched on again!

When the drive shafts of encoder and conveyor are not correctly aligned, the
unbalanced mass at the encoder shaft will cause the destruction of the encoder.

During assembly it must be taken into consideration that the encoder is attached to the
drive shaft of the conveyor passing at the standard device and at the rejector.

Do not work on the encoder shaft with a hammer or other objects.

Assembling the encoder

Assembly is subdivided into:

Preparing the drive shaft (provided that a tapped hole in the drive shaft of the conveyor system is not
already available), page 10

Mounting the encoder, page 11

Assembling the encoder (short variant), page 13

14 ASSEMBLY INSTRUCTIONS
 Assembly to conveyors available on site
There are different variants to assemble the encoder holder. During assembly it is thus possible to deal with
the mechanical conditions of a conveyor system available on site individually.

In the case of a HEUFT conveyor system the encoder can be assembled directly as
tapped holes already exist. In the case of a conveyor system on site it may be
necessary that the user makes appropriate tapped holes or other holes himself if they
do not yet exist in the conveyor system.

Electrical installation
Connect the encoder to the terminals (24 V DC (PELV)) provided on the standard device (refer to the wiring
11.00.007

diagram of the standard device).
