characteristic curve. The following settings are possible:
Value range:
6-bar devices: 1.2–6 bar (17–87 psi)
10-bar devices: 2–10 bar (29–145 psi)
Increments: 0.1 bar (1 psi)
Factory setting:
6-bar devices: 6 bar
10-bar devices: 10 bar
Display
Language
Defines the language in which the control/navigation is shown on the display.
The following settings are possible:
Value range: German, English, French
Factory setting: English
Units
Defines the unit system in which the pressure-related values are displayed.
Pressure-related values include the actual pressure value, the manually or
externally specified pressure set point, the hysteresis threshold values,
and the pressure range adjustments. The following settings are possible:
Value range: bar, psi
Factory setting: bar
Contrast
Defines the contrast settings for the display. The following settings are possible:
Value range: 15%–32%
Increments: 1%
Factory setting: 25%
Dynamics
Defines the response sensitivity for displaying the set point and actual value.
The following settings are possible:
Value range: high, middle, low
Factory setting: middle
Backlight
Defines the time when the display backlight automatically switches off if no button
is pressed. The following settings are possible:
Value range: 1 min, 3 min, 5 min, On
Factory setting: 3 min
Analog I/O (analog interface)
The menu item "Analog I/O" is not available with EV03 pressure regulators
for IO-Link.
With EV03 pressure regulators, the type of analog interface can be selected.
The following settings are possible:
Value range:
Set point and actual value 0–10 V,
Set point and actual value 4–20 mA,
Set point and actual value 0–20 mA,
Set point 0–10 V, actual value: switch output,
Set point 4–20 mA, actual value: switch output
Set point 0–20 mA, actual value: switch output
Factory setting: Corresponding to your configuration (see chapter "Product
identification").
Switched Out
The menu item "Switched Out" is not available with EV03 pressure
regulators for IO-Link.
Hysteresis
The hysteresis defines the max. permissible deviation from the standard. The switch
output is active within these limits.
The following settings are possible:
Value range: 0.1–1.0 bar (1–15 psi)
Increments: 0.1 bar (1 psi)
Factory setting: 0.1 bar
defines the highest pressure value of the
Delay
Defines the delay period after which the switch output is set to active once a stable
value within the defined tolerance range has been reached. The following settings
are possible:
Value range: 50–1000 ms
Increments: 10 ms
Factory setting: 50 ms
Force
In the "Force" menu item, users can set their own set point. As long as the user
remains in the edit level of this menu item, the manually set value is maintained.
The external set point is overwritten. Timeout monitoring that exits the menu
is deactivated in this menu item. The device controls the manually set value until
the user exits the menu.
Increments: 0.1 bar (1 psi)
Value range: p to p
min max
Lock
Defines the access lock for the device. The following settings are possible:
Value range: integer values in the range from 1–9999, lock off
Factory setting: lock off
Memory
Manages memory. The following settings are possible:
Value range:
Cancel (exit the menu item without saving),
Save (all settings are saved),
Reset (all settings are reset to factory settings).
Changed settings must be saved, otherwise they will not be available
in the event of a power failure or upon the next start-up.
9 Data Structure for EV03 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/6 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.

1) If the test bit is set, this is reported in the actual value.
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.
