Change-over via digital input MODE
Switching behaviour for coding
Low active
:
(Default factory setting)
●
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 (standard: +24 V DC) = Remote OPEN-CLOSE:
The actuator reacts to operation commands OPEN, STOP, CLOSE.

Input of setpoint position
In Profibus DP version, the setpoint position is transmitted via the fieldbus interface,
channel 1 or channel 2.
Configuration (process representation) is defined via the GSD file only.
Information
If required, download the GSD file (General Station Description) from the Internet:
www.auma.com
Actuator controls with two additional analogue inputs
The setpoint position can also be fed via an analogue input. In this case, one of the
inputs AIN 1 or AIN 2 has to be configured as setpoint position.
Required user level:
Specialist (4)
.
Device configuration M0053
I/O interface M0139
Analogue inputs M0389
Signal AIN 1 M0135
Signal AIN 2 M0138
Setting value:
Setpoint position
Information
Actuator controls will only react to the additional analogue input, if high level
(standard: +24 V DC) is present at the
I/O INTERFACE
input (refer to wiring dia-
gram).
8.6.12.
Input range of setpoint position
The input range defines the signal range, i.e the initial and the end value of the
setpoint signal. For example: 0 – 20 mA, 4 – 20 mA or another value.
In Profibus DP version, the input range for setpoint position is set to 0.0 % ... 100.0
%.
Actuator controls with two additional analogue inputs
If the setpoint position is fed via an analogue input, the signal range of the respective
input (AIN1 or AIN2) has to be correctly set. The configuration is then made via
parameters.
