AUMA AC 01.2 User Manual

This prevents end position(s) OPEN and/or CLOSED from being approached in
modulating duty. The actuator stops when reaching the set limit value.
For OPEN-CLOSE control (LOCAL or REMOTE OPEN-CLOSE operation mode),
this limitation is not active.The valve can then be run into the end positions either
via the local controls or from remote.

8.4.9. Change-over between OPEN - CLOSE control and setpoint control
For actuators equipped with a positioner, it is possible to change over between OPEN
- CLOSE control (Remote OPEN-CLOSE) and setpoint control (Remote
SETPOINT).
Change-over via fieldbus command:
For control via fieldbus interface, the change-over is done via fieldbus command
Fieldbus SETPOINT.
Switching behaviour:
●
Fieldbus SETPOINT = 0 = Remote OPEN-CLOSE:
The actuator reacts to operation commands OPEN, STOP, CLOSE
●
Fieldbus SETPOINT = 1 = Remote SETPOINT:
The actuator reacts to a setpoint signal (e.g. 0,0 ... 100,0 %)
If the operation commands are not transmitted via fieldbus commands, but via
<Additional inputs> or additional <Parallel interface>, a digital input for the MODE
signal has to be available and configured for change-over.
