Access levels
The following two access levels are provided for operation of the positioner:
Control level (A: AUTO, B: MANUAL)
This level is automatically set each time the positioner is switched on. You can toggle between the AUTO and MANUAL
operating modes at this level.
In the MANUAL mode, the valve can be operated with the
+
key
and
-
key. The specified value is activated only when the
→

In the AUTO operating mode, the valve is controlled by a setpoint signal.
Configuration level (C: CONFIG)
Different parameters can be set at this level (see list of parameters on page 12).
This allows for optimal adaptation to your specific application.
