Modulating output (AO)

8.2.1 Purpose and activation
The AO x (modulating output) function block generates a continuous DC 0...10 V
output signal for a modulating actuator with a corresponding input.
The AO x function block is not available with the RLU220 controller.
To activate the AO x function block, you must assign an output (Y x) to it.
8.2.2 Function
You can connect the load signal for the modulating output from the sequence
controller to the modulating output.
Additionally, it is also possible to use an analog input (IN X) as the load signal. If
one or more (maximum 2) internal load signals and the external load signal are
connected at the same time, the controller uses maximum selection.
For example, this provides for combination of the air cooling coil signal from an
external dehumidification controller with that from a temperature controller.
The external signal is considered only if the controller operates in Comfort or
Economy mode!
You can invert any output. Meaning:
INVERS = NO: 0...100% load = 0...100% output
INVERS = YES: 0...100% load = 100...0% output
If the controller has an analog output and is switched off during operation (input D1
= Protection), the output signal behaves as follows:
INVERS = NO: 0% output
INVERS = YES: 100% output
