8 Data Structure for EV1X with IO-Link
Connection
Process data
Set points for the 16-bit pressure regulator
The control or the IO-Link master sends the output data (set points) with a length of
2 bytes to the pressure regulator. The set point is sent in bits 0–9. Bits 10–14 are
ignored. Bit 15 is used as a test bit. For values ≥ 1000, the following applies:
W
Values ≤ 1000: The pressure is controlled corresponding to the meaning of
bits 0–9.
W
Values 1001 to 1023:The maximum pressure (10 bar) is controlled.
W
Values ≥ 1024: Bits 10–14 are ignored. The pressure is controlled corresponding
to the meaning of bits 0–9.
In 10-bar devices, the values 0–1000 correspond to an output pressure of 0 to
10 bar. The resolution is 10 mbar.

Actual values of the 16-bit pressure regulator
The pressure regulator sends the input data (actual values) with a length of 2 bytes
to the control. The actual value is sent in bits 0–9. In 10-bar devices, the
values 0–1000 correspond to an output pressure of 0 to 10 bar. The resolution is
10 mbar.

Communication errors due to timeout!
Communication errors (timeout) can arise if the IO-Link master executes a
"parameter save".
O Make sure that the IO-Link master does not execute a parameter save while
you make entries.

Comment
Undervoltage (UA < 19.2 V),
IO-Link allows for lower voltages but
the device does not work as intended
below this threshold.
Parameters were transferred
incorrectly or incorrect parameters
were transferred and not accepted.
NOTICE
Parameters are included in the contents of the configuration file.
The parameters sent to the device via the IO-Link will overwrite the existing
parameters on the device!
No parameter handler is used in this process.

9 Commissioning the EV1X Pressure
Regulator
Before commissioning the EV1X pressure regulator, you must first assemble it and
connect it to your system.

Danger due to loose screws or connections!
Danger of injury!
O Check all screws and connections before starting the system.
Danger of burns caused by hot surfaces!
Touching the surfaces of the EV1X during operation could cause burns. The
temperature on uncoated metal can exceed 64°C and on polymers can exceed
85°C.
O Let the device cool off before working on it.
O Do not touch the device during operation.
Shortened product service life if operated without operating pressure!
Operation with the supply voltage and set point applied, but no operating
2 1 0
pressure, can result in a shortened product service life.
I I I O Never operate the device without compressed air.
Commissioning may only be carried out by qualified electrical or pneumatic
personnel or an instructed person under the direction and supervision of
qualified personnel (see "Personnel qualifications").
O Always observe the system documentation when commissioning the relevant
system component.
1. Make sure that the system is not under pressure.
2. Check all screws and connections once more before starting the system.
3. Switch on the power supply.
4. Check the LED displays on all modules.
– The UL and UA LEDs must be green before switching on the operating
pressure.
– The DIAG LED must be off before commissioning.
If the LEDs are in the correct state:
5. Switch on the compressed air supply.
Make sure that the operating pressure lies at least 1 bar above the maximum
output pressure to be controlled. Otherwise, only a reduced output pressure
range is available.

10 Cleaning and servicing

O Close all openings with suitable safety devices so that no cleaning agent can
enter into the system.
O Never use solvents or aggressive detergents. Only clean the product using a
slightly damp cloth. Only use water and, if necessary, a mild detergent.
O Do not use high-pressure cleaners for cleaning.
O Do not use compressed air for cleaning (blowing off) the maintenance unit or
equipment.
