Absolute Encoder – PROFINET

All movable adjusting elements need tolerance in both
axial and radial direction in order to equalize shifts by
temperature and of mechanical nature. Tighten both fixing
and clamp ring screws firmly.
Electrical installation
- Do not modify encoder in any electrical way and carry
out any wiring work under power supply.
- Any electrical connection and plugging-on whilst under
power supply is not permitted.
- A separate encoder supply has to be provided with con-
sumers with high interference emission.
- Installation of the whole system has to be according
to EMC standards. Installation environment as well as
wiring have an impact on the encoder's EMC. Encoder
and supplying lines are to be in separated locations or
remote from lines with high interference emission (fre-
quency transformers, protections, etc.).
- Encoder case and supply cable have to be completely
screened.
- Ground (PE) encoder by using screened cables. The
braided shield has to be connected to cable gland or
plug. Grounding (PE) on both sides is recommended.
Ground the case by the mechanical assembly, if latter
is electrically isolated a second connection has to be
provided. Ground cable screen by the subsequently
connected devices.
- In case of ground loop problems at least grounding on
one side is imperative.
Any disregard may lead to malfunctions, material damage
and personal injury.

General remarks
Additional information
The installation instruction is supplementary to already
existing documentation (e.g. catalog, data sheet, manual).
It is imperative to read the manual carefully prior to star-
ting the device.

Appropriate use
- The encoder is a precision measuring device. It is expli-
citly designed for registration of angular positions and
revolutions as well as evaluation and supply of measu-
ring values as electric output signals for the subsequent-
ly connected device. The encoder must not be used for
any other purpose.
Start up
- Installation and assembly of the encoder only by electri-
cally skilled and qualified personnel.
- Consider also the operation manual of the machine
manufacturer.
Safety instructions
- All electrical connections are to be revised prior to star-
ting the system.
- Incorrect assembly and electrical connections or any
other inappropriate work at encoder and system may
lead to malfunction or failure of the encoder.
- Any risk of personal injury, damage of the system or
company equipment due to failure or malfunction of the
encoder has to be eliminated by corresponding safety
measures.
- Do not operate encoder beyond the limit values stated
in the data sheet.
Any disregard may lead to malfunctions, material damage
and personal injury.

Follow also the instructions of the respective supplier.
- Press mating connector softly into the plug.
- Turn mating connector carefully until the code mark is
interlocking the corresponding space provided by the
plug. Insert bushing completely. Tighten the nut as far
as possible.
An optimized connection between encoder case
and the braided shield of the connection cable is
only achieved by the braided shield being placed
generously onto the connector and the nut being
secured firmly.

Disposal
Encoder components are to be disposed of according to
the regulations prevailing in the respective country.
Transport and storing
- In original packing only.
- Do not drop or expose encoder to major shocks.
Assembly
- Open clamping ring completely before mounting the
encoder.
- Avoid punches or shocks on case and shaft.
- Avoid case distortion.
- Do not open or modify encoder in any mechanical way.
- The spring arm of the spring coupling has to be free
movable.
Hollow shaft, bearing, glass disc or electronic
components might be damaged and a secure
clamping ring
operation is no longer guaranteed.
Hollow shaft mounting
Mounting with clamping ring
Plug encoder completely onto drive shaft (ISO-fit f7) and
tighten clamping ring firmly. The drive shaft must pene-
drive
trate the encoder's hollow shaft to a depth of at least
shaft
35 mm.

Exchange bus cover
The bus cover is to be stored and transported whilst in
the ESD bag only. The bus cover has to fit the case tightly
and has to be firmly secured by screws.
Remove bus cover
- Unscrew both fixing screws of the bus cover.
- Loosen both bus cover elements carefully and remove it in
axial direction.
DUO-LED
Plug on bus cover
- Plug the bus cover carefully onto the D-SUB plug of the
basic encoder, then push it over the rubber seal. Avoid
the case getting wedged. The bus cover has to fit tightly
the basic encoder.
- Tighten both fixing screws firmly and conformable.
- An optimized connection between encoder case and the
braiding shield of the supply cable is only achieved by
a complete and close fit of the bus cover onto the basic
encoder (interlock).

Spring coupling
Fasten spring coupling at the fixing holes provided on housing by means of screws.
Slide encoder onto the drive shaft and fasten spring coupling at the surface provided
with screws.
