AUMA AC 01.2 User Manual

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.
8.4. 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 the 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.
8.4.1. Positioner: activate
Required user level: Specialist (4) or higher.
Device configuration M0053
Application functions M0178
Activation M0212
Positioner M0158
Default value: Function not active
Setting values:
Function not active
Function <Positioner> deactivated.
Function active
Function <Positioner> activated.
8.4.2. Adaptive behaviour: activate deactivate
Adaptive positioning may reduce the number of starts and compensate for the overrun
of the actuator.
Customer settings M0041
Positioner M0145
Adaptive behaviour M0147
Default value: Adaptive I
Setting values:
Off
Adaptive behaviour switched off.
Adaptive I
Adaptive behaviour for precise positioning (high positioning accuracy).
Due to the inertia of both actuator and valve, the valve position changes only slightly
after switching off the actuator (overrun). The positioner determines the resulting
error between setpoint and actual value for both directions and automatically adapts
the inner dead bands Xi and therefore switching point P2.
