Displays in the AUTOMATIC mode

The following displays are possible for the position controller.
Actual position of valve actuator:
XPOS___ (0...100%)
Set position of valve actuator: WPOS___ (0...100%)
It is possible to change over between these displays by operating the „arrow keys“.
Process controller active
When the process controller is active, the following values can be displayed:
Actual value of process variable (actual process value):
PV ____ (-99.9...999.9)
Desired value of process variable (desired process value): SP ____ (-99.9...999.9)
Actual value of valve drive: XPOS ____ (0...100%)
Desired value of valve drive: WPOS ____ (0...100%)
The arrow keys can be used to switch between these four displays. The «down arrow» key allows
paging through displayed values in the above sequence.
If the additional function PCONTROL SETPOINT INTERN (set desired value via keyboard) was spe-
cified during configuration, pressing either of the two arrow keys for more than 3 seconds while SP
(Setpoint) is shown in the display activates the mode for changing the desired process value. If the key
is released after this time, the first digit of the desired process value flashes on and off. This digit can
be changed by pressing the key again. After confirmation with the HAND/AUTOMATIC key, the set
value is accepted. The same process can be applied to the other digits. When the fourth digit has been
confirmed, the mode switches back.
