AUMA ACVExC 01.2 Series - Positioner (Operation Mode Remote SETPOINT); Positioner: Activate

Execute operation commands via digital input:
Designation of digital input OPEN / CLOSE
(wiring diagram designation: OPEN/CLOSE
Default setting
●
Input OPEN / CLOSE = low level (0 V DC or input open):
Actuator runs in direction CLOSE.
●
Input OPEN / CLOSE = high level (standard: +24 V DC):
Actuator runs in direction OPEN.
Configuration of digital input
For the two-wire control, a digital input for the OPEN / CLOSE signal has to be
configured.
Required user level: Specialist (4)
Device configuration M0053
I/O interface M0139
Digital inputs M0116
Example
Use input DIN 5 for signal OPEN / CLOSE:
Parameter: Signal DIN 5 M0122 = OPEN/CLOSE
Information
The logic for the digital inputs may be inverted. Depending on the parameter setting
(e.g. Coding DIN 6 M0128), the input is either High active or Low active. Default
setting is High active.
8.5. Positioner (operation mode Remote SETPOINT)
Conditions
This function requires one of the following equipments within the actuator:
●
Electronic control unit (non-intrusive version)
●
Potentiometer
●
Electronic position transmitter EWG/RWG
Further conditions for the positioner operation mode:
●
Positioner enabled and activated.
●
Operation mode Remote (selector switch = position Remote control).
Characteristics
The positioner records setpoint position E1 and actual position value E2 for
comparison. Depending on the detected deviation, the actuator motor then runs in
direction OPEN or CLOSE.
Information
●
If the actuator is controlled via a setpoint (e.g. 0 – 20 mA), the status indication
S0003 on the display shows both setpoint position E1 and actual position value
E2.
●
If the status indication S0003 only shows actual position value E2, OPEN-
CLOSE control is active and there is no setpoint control via the positioner. In
this case, you have to change-over to setpoint control first, refer to <Change-
over between OPEN-CLOSE control and setpoint control> chapter.
