AUMA AC 01.2 User Manual

For torque seating, the end positions OPEN and CLOSED of the limit switching
should be set as close as possible to the end positions of the valve to minimise the
deviation of the feedback.
Torque
Torque feedback E6
Condition: MWG position transmitter in actuator.
The zero point is in the centre of the selected output range (10 mA or 12 mA). The
torque in direction CLOSE is indicated with 0 – 10 mA or 4 – 12 mA, the torque in
direction OPEN with 10 – 20 mA or 12 – 20 mA. For 127 % of the maximum nominal
output torque, 0 or 4 mA are indicated in direction CLOSE, and 20 mA are indicated
in direction OPEN.

Input AIN 1
Analogue value transmitted via AIN1 (refer to wiring diagram) to the actuator.
Condition: An analogue signal (e.g. 0 – 20 mA) is connected to the analogue input
AIN 1.
Input AIN 2
Analogue value transmitted via AIN 2 (refer to wiring diagram) to the actuator.
Condition: An analogue signal (e.g. 0 – 20 mA) is connected to the analogue input
AIN 2.
Fieldbus AOUT 1
Analogue value transmitted from the fieldbus to the actuator.
The value is transmitted via fieldbus in per mil (value: 0 – 1000) and can be sent as
continuous value. e.g 4 to 20 mA, via output Signal AOUT 1.
Fieldbus AOUT 2
If another analogue value is transmitted via fieldbus to the actuator, it can be sent
as continuous value. e.g 4 to 20 mA, via output Signal AOUT 2.
Temp. ctrls norm. ‰
Actuator controls temperature (normalised) in per mil.
Condition: MWG position transmitter in actuator.
Temp. ctrl unit norm ‰
Control unit temperature (normalised) in per mil.
Condition: MWG position transmitter in actuator.
5.4.2. Signal range of analogue output 1
Required user level: Specialist (4) or higher.
Device configuration M0053
I/O interface M0139
Analogue outputs M0335
Signal range AOUT1 M0129
Default value: 0 - 20 mA
Setting values:
0 - 20 mA
Analogue output 1 generates a 0 – 20 mA signal.
4 - 20 mA
Analogue output 1 generates a 4 – 20 mA signal.
20 - 0 mA
Analogue output 1 generates a 20 – 0 mA signal.
20 - 4 mA
Analogue output 1 generates a 20 – 4 mA signal.
X to Y mA
The signal range (X-Y) of the analogue output can be freely configured using two
parameters.
