Setting ranges: 0.0 ... 100.0 % of setting range
12.4.9. 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).
Actuators with parallel interface:
For the change-over, a digital input for the MODE signal has to be available and
configured.
Actuators with fieldbus or communication interface:
For control via fieldbus interface, 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 an additional <Parallel interface>, a digital input has to be
available for change-over of the MODE signal and be configured.
Configuration of digital input
Required user level: Specialist (4).
Device configuration M0053
I/O interface M0139
Digital inputs M0116
Example
Use input DIN 1 for change-over:
Parameters: Signal DIN 1 M0118
Setting value: MODE
Information
The logic for the digital inputs may be inverted. Depending on the parameter setting
(e.g.Coding DIN 4M0126), the input is either High active or Low active. Default setting
of MODE input is Low active.
Change-over via digital input MODE
Switching behaviour for coding Low active:
(default setting in the factory)
●
Input MODE = low level (0 V DC or input open) = Remote SETPOINT:
The actuator reacts to a setpoint signal (e.g. 0/4 – 20 mA)
●
Input MODE = high level (default: +24 V DC) = REMOTE OPEN-CLOSE:
The actuator reacts to operation commands OPEN, STOP, CLOSE.
12.4.10. Input of setpoint position: Parallel interface
The setpoint position is generally led via input AIN1, but can also be led via AIN 2.
Required user level: AUMA (6).
