8.8.6 AO Function
This menu is for the configuration of the analog output.
After registration, each analog output checks the current signal for plausibility. Signal deviations of more than
5% from the nominal value will generate an error message (causes: short circuit or interruption of cable,
actuator not connected).
The steepness of the current signal can be adjusted in the range of 10 to 100% in case of local control.
If several measuring points are assigned, you can define whether the minimum, the maximum or the average
of all the assigned signals is output. It is likewise possible to define which signal of the measuring points
(source) is output.
If the 4 - 20 mA signal is used as a safe signal (SIL level), the following mandatory parameters must be
used:

use only the relay functionality.
