3.3 Description
The GEMÜ Q50 eSyStep 2/2-way pinch valve is motorized.
The eSyStep actuator is designed as an actuator with integ-
rated positioner. The valve guides a tube which is com-
pressed from above by a compressor to control and regulate
media. The compressor's specially developed contour and
the tube holder's contour minimize the strain on the tube and
thus increase the tubes' service life. Tubes can be safely in-
serted and removed in simple steps and without tools. An
optical and electrical position indicator is integrated as
standard.

3.4 Function
The product controls or regulates (depending on version) a
flowing medium by being closed or opened by a motorized
actuator.
The product is equipped as standard with a mechanical posi-
tion indicator as well as an electrical position and status in-
dicator.

11 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
connectors and the current consumption of the actuator are non-compliant with the IO-Link specification.
11.1 Operation on IO-Link
11.1.1 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.

11.1.2 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.

11.1.3 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
result 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.

11.1.4 Direct operation on the IO-Link master
Basics
If the product is to be operated on an IO-Link master, it must be ensured that the GND levels in the product and in the IO-Link
master have the same potential so that there are no compensating currents which would cause damage in the system. This
can be made possible using several procedures.
11.1.4.1 Identical power supply
The IO-Link master is operated from the same power supply as the product.
●Connect pin 4 (CQ) of the master with pin 6 of the product.
However, pin 3 (L-) of the master should not be connected to pin 2 (GND) of the product under any circumstances.
This prevents a ground loop and no unexpected high currents can occur via pin 3 (L-) which can damage the master.
