10.1 Description of parameters
1: SETPOINT
Range of analog setpoint input (Voltage:0-10 V or current: 0-20 mA, 4-20 mA).
2: INIT ALL
Initialisation
Automatic initialisation is started by pressing the
+
or
-
and
→
→
→
→
→
keys (> 3sec). The individual steps of initialisation are
displayed with
„run 1
“ to
„run 5
“.
The positioner’s control parameters to drive the valve are optimised during initialisation.
3: DEFAULT STATE
Standard setting or recovery of factory settings and resetting of initialisation.
The positioner is set to „Default“ by pressing the
+
or
-
and
→
→
→
→
→
keys (> 3 sec).
The positioner must be initialised again after having been set to „Default“ .
All previous actuator parameters are deleted (initial state).
11: X-DIRECTION
Direction of manipulated variable.
Setting of the direction of action (rising or falling) of the display and position feedback.
12: ALARM FUNCTN
Activates or deactivates the alarm function.
The response threshold of the alarms (limit contacts) depends on the scale of POSITION (mechanical travel).
