2 Safety information
The safety information in this document refers only to an indi-
vidual product. Potentially dangerous conditions can arise in
combination with other plant components, which need to be
considered on the basis of a risk analysis. The operator is re-
sponsible for the production of the risk analysis and for com-
pliance with the resulting precautionary measures and re-
gional safety regulations.
The document contains fundamental safety information that
must be observed during commissioning, operation and main-
tenance. Non-compliance with these instructions may cause:
•Personal hazard due to electrical, mechanical and chemical
effects.
•Hazard to nearby equipment.
•Failure of important functions.
•Hazard to the environment due to the leakage of dangerous
materials.
The safety information does not take into account:
•Unexpected incidents and events, which may occur during
installation, operation and maintenance.
•Local safety regulations which must be adhered to by the
operator and by any additional installation personnel.
Prior to commissioning:
1. Transport and store the product correctly.
2. Do not paint the bolts and plastic parts of the product.
3. Carry out installation and commissioning using trained
personnel.
4. Provide adequate training for installation and operating
personnel.
5. Ensure that the contents of the document have been fully
understood by the responsible personnel.
6. Define the areas of responsibility.
7. Observe the safety data sheets.
8. Observe the safety regulations for the media used.
During operation:
9. Keep this document available at the place of use.
10. Observe the safety information.
11. Operate the product in accordance with this document.
12. Operate the product in accordance with the specifications.

3.3 Description
The GEMÜ 566 2/2-way straight seat control valve has a body
with an integrated control mechanism. Manual, pneumatic
and motorized actuator types are available. The GEMÜ 566
valve was specially developed for controlling small quantities
and allows flow rates from 63 l/h to 2500 l/h.
3.4 Function
The product has a valve body with an integrated control
mechanism which can be controlled by various actuator types
(manual, pneumatic and motorized). The medium and actu-
ator are hermetically separated.

12 Specific data IO-Link (pin 6)
IO-Link process data and parameters can be set via pin 6 for the motorized linear actuator eSyStep. The assignment of the con-
nectors and the current consumption of the actuator are non-compliant with the IO-Link specification.
12.1 Operation on IO-Link
12.1.1 Operation on PLC as a 24 V device
The motorized actuator GEMÜ eSyStep can be operated directly in a PLC control unit without limitations. Technical data of the
product and of PLC must be complied with.

12.1.2 Operation on PLC and additional parameterization via USB master with galvanic isolation
Basics
When operating the product on a PLC control unit, a parameterization via a USB IO-Link master is possible at the same time. In
this case, a galvanically isolated USB interface must be used. The PC/laptop can be used as usual and all peripheral devices can
remain connected.
Connection
1. Connect pin 3 (L-) of the master with pin 2 (GND) of the product.
2. Connect pin 4 (CQ) of the master with pin 6 of the product.
During IO-Link operation, pin 6 cannot be evaluated by the PLC control unit as an output signal.

12.1.3 Operation on PLC and additional parameterization via USB master without galvanic isolation
Basics
Only one laptop can be used if no galvanic isolation is available for the USB interface during communication via a USB IO-Link
master. No other peripheral devices may be connected to the laptop. The laptop may only be operated without a power supply
unit.
If further peripheral devices and the power supply unit are not disconnected, different ground potentials to the product can res-
ult in excessive compensating currents. These can damage the USB interface of the laptop, the connected peripheral devices or
the USB IO-Link master.
Connection
1. Connect pin 3 (L-) of the master with pin 2 (GND) of the product.
2. Connect pin 4 (CQ) of the master with pin 6 of the product.
During IO-Link operation, pin 6 cannot be evaluated by the PLC control unit as an output signal.
