16 Annex A (configuration instructions)
The actuator is configured with the TROVIS-VIEW software (
u
EB 6661).
16.1 Input signal
The input signal determines the actuator stem position. A voltage or current signal can be
used as the input signal.
The default lower and upper range values of the input signal are 0 to 10 V or 0 to 20 mA.
At least 2.5 V or 5 mA (depending on the input signal used) must separate the upper and
lower range values.

Click 'Settings' folder ('Inputs and outputs').
The settings for the input and output signal are shown:
Settings\Inputs and outputs\Input signal
Input signal WE Adjustment range
Lower range value 0.0 V or 0.0 mA 0.0 to 7.5 V or 0.0 to 15.0 mA
Upper range value 10.0 V or 20.0 mA 2.5 to 10.0 V or 5.0 to 20.0 mA
16.1.1 Split-range operation
The input signal range can be adapted, e.g. to achieve a plant operation characteristic by
connecting two or more actuators in parallel (split-range operation).
Example: Two valves regulate the process medium in one common pipeline to achieve a
large rangeability. One valve opens with a 0 to 5 V input signal, while the second valve also
opens when the input signal increases further (5 to 10 V) and the first valve remains open.
The two valves close in the reverse order.
