Volume restriction Q
The volume restriction is used to adapt the
air delivery to the actuator size. Two fixed
settings are possible depending on how the
air is routed to the actuator. Refer to sec-
tion 7.2.

Icons assigned to certain codes and func-
tions are indicated on the display. The bar
elements indicate the system deviation that
depends on the sign (+/–) and the value.
One bar element appears per 1 % system
deviation.
If the positioner has not yet been initialized,
the lever position in degrees in relation to
the longitudinal axis is indicated. One bar
element corresponds to approximately a 5°
angle of rotation.
If the fault indication icon appears on
the display, press or until

WARNING!
Do not perform a start-up while the process
is running.
On applying supply air and the electric con-
trol signal, the control valve may move
through its entire travel range/rotational an-
gle range depending on the setting.
4
Connect the supply air (Supply 9).
4
Connect the 4 to 20 mA signal (terminals
+11/–12). Do not touch the key panel!
Note: After connecting the electrical signal
(power supply), the positioner performs a
calibration of the capacitive keys which
takes approx. three seconds. During this
time, do not touch the key panel. Otherwise,
the keys will not work properly.
Disconnect and reconnect the electrical sig-
nal to restart the calibration of keys.
LOW on the display indicates that the refer-
ence variable is lower than 4 mA (0 %).
The positioner is ready for operation with its
default settings for most applications, pro-
vided it has been mounted properly.
Note: The positioner needs to be initialized
again after the position of the volume re-
striction has been changed.
The positioner also needs to be initialized
again after the setting for the fail-safe posi-
tion has been changed.
