Parameter
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.
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.

10 Commissioning the EV03 Pressure
Regulator
Before commissioning the EV03 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 EV03 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
pressure, can result in a shortened product service life.
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").
Comment
Undervoltage (UA < 19.2 V),
IO-Link allows for lower voltages but
the device does not work as intended
below this threshold.

CAUTION
NOTICE
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.
11 Disposal
O Comply with national regulations regarding disposal.

12 Troubleshooting

Table 14 contains an overview of malfunctions, possible causes, and remedies.
If you cannot remedy a malfunction, please contact AVENTICS GmbH.
The address is printed on the back cover of these instructions.

the EV03 operating line and
results in a large pressure
drop in the device.

Remedy
Connect the power
supply.
Check the polarity
of the power supply.
Switch on system
component.
Stipulate a set point.
Connect the operating
pressure.
Increase the operating
pressure
Reduce air consumption.
Adjust the operating
pressure to at least 1 bar
above the maximum
output pressure to be
controlled.
replace, if necessary.
Exchange the pressure
regulator.
Stipulate the correct type
of set point.
Stipulate the correct set
point.
Check the exhaust line.
Stipulate valid
parameterization.
Exchange device since
a pressure sensor is
defective.
