16.3 Explanation of parameters
1: Set Point
Range of analogue set value input (Voltage: 0-10 V or power:
0/4-20 mA).
2: Init All
Initialization
Press and press and hold the key (> 3 sec) to start the
automatic initialization. The progress of the initialization is
shown with RUN 1 to RUN 5 in the display.
During the initialization process, the positioner optimizes its
control parameters for controlling the valve concerned.
NOTICE
▶ This process must be carried out in order to be able to se-
lect automatic or manual operation and should be re-
peated after every change to the mechanical end posi-
tions (e.g. seal replacement on the valve/operator re-
placement).
3: Default State
Default setting
Return to default setting and reset initialization. Press
and press and hold the key (> 3 sec) to set the controller
to Default.
NOTICE
Setting to default
▶ After setting to Default, the product must be reinitialized.
All actuation parameters established so far are deleted.
The parameters D.Refresh and the New Code 1-3 are not
taken into account.
11: X-Direction
Correcting variable direction
Here the display direction (rising or falling) and the position
feedback can be adjusted.

12: Alarm Functn
Activates or deactivates the alarm function
The reaction of the alarms (limiting contacts) relates to the
position measurement (mechanical distance).

13: Level Alarm 1
Switch point for Alarm 1. When the switch point has been
reached, digital output A1 (24 V DC output) is switched.
14: Level Alarm 2
Switch point for Alarm 2. When the switch point has been
reached, digital output A2 (24 V DC output) is switched.
15: Error Functn
Function of the error message output (24 V DC output)
The table shows which functions are relevant to the setting of
the output at which setting value.
