16 Annex A (configuration instructions)

Note

The actuator is configured with the TROVIS-VIEW software (u EB 6661).

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.

Note

At least 2.5 V or 5 mA (depending on the input signal used) must separate the upper and

lower range values.

Î Click 'Settings' folder ('Inputs and outputs').

The settings for the input and output signal are shown:

Settings\Inputs and outputs\Input signal

Input signal

Lower range value

Upper range value

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.
