Settings and displays
The factory settings are described in the following sections.
After connecting the device to the power supply, it displays the standard screen. The
measuring and switching functions are operational.
On the display, the "Lock" symbol (25) indicates whether the device is protected by a
password or whether you can navigate the menu structure without a password.
The device requires a password.
The device does not require a password.
Enter password
The device displays the standard screen.
The lock symbol is closed.
O Press the
button.
This takes you to the edit level where you can use the
the password.
O Press the
button to confirm the password.
If the password is correct, you are taken to the menu level.
The lock symbol is open.
If the password is incorrect, you are returned to the standard screen. The
lock symbol is closed.
Resetting the password
If you have forgotten the password, you can reset it as follows:
O Press and hold both arrow buttons at the same time while switching on the
power.
You are immediately taken to the "Lock" menu item without a request for the
unlock code (see below, section "Lock").
Automatic return to the standard screen (timeout)
If you do not make any entries for longer than one minute, the display automatically
returns to the standard screen from within all menu levels, with the exception of the
manual set point specification.
If the device is password-protected, you have to enter the password again to reach
the menus.
Manual return to the standard screen
Pressing and holding the button for longer than 1 s takes you one menu level
higher (Escape).
O Repeat the process until you have reached the standard screen.
User adjustment active
If the user adjustment active symbol (24) is displayed, one or more of the
following factory settings was changed via button input on the device:

Information
Device no.
Displays the device's material number, e.g. R414011384.
Serial nr
Displays the device's serial number, e.g. 123456.
Software
Displays the installed software version, e.g. V.1.0.0.0.
Ctrl type
Displays the regulator type in factory settings (see section "Product identification" in
chapter 5), e.g. 010-L12
W
1st to 3rd position: set point, e.g. "010" (0–10 V analog) or "IOL" (control via
IO-Link)
W
5th position: flow direction
– L = left to right
– R = right to left
– C = continuous pressure supply
W
6th and 7th position: connection thread
– 12 = G1/2
– 38 = G3/8
– 34 = G3/4
– 1 = G1
Control
Dynamics
The dynamics define the control behavior of the control loop.
The following settings are possible:
Value range: speed opt., plug&play, value opt.
and buttons to enter
W
Speed opt.: fastest control upon set point change,
requires the fewest switching cycles for control;
possibly with overshooting
W
Plug&Play: standard control loop: no optimized
control behavior; ideally, minimal overshoot, more
value opt. than speed opt.
W
Value opt.: control loop with optimized values,
requires the most switching cycles upon set point
change; without overshoot; for applications that are
to run sluggishly
Factory setting: speed opt.
Accuracy
The accuracy defines the active zone of the pressure regulator.
The following settings are possible:
Value range: optimized, Plug&Play, generous
W
Optimized: the control is active until the deviation is less than 5 mbar. The control
is reactivated if the deviation exceeds 8 mbar.
W
Plug&Play: the control is active until the deviation is less than 20 mbar. The
control is reactivated if the deviation exceeds 25 mbar.
W
Generous: the control is active until the deviation is less than 50 mbar. The
control is reactivated if the deviation exceeds 100 mbar.
Factory setting: Plug&Play
