Connections and functions

The following illustration shows the function block connections as shown on the
configuration sheet:

MODE 3: 2X-INV
Y Y
See below on how to assign connections (inputs and outputs).
The function block provides these functions :
• Limit the input signal's low and high value (MIN VAL, MAX VAL) for each of the
output signals AO 1 and AO 2.
• Adapt the low and high value (MIN POS, MAX POS) for each of the output
signals AO 1 and AO 2.
• Invert output signals AO 1 and AO 2.
Corresponding signals in the DC 0...10 V range appear at the outputs.
The following function diagrams illustrate the above statements. Limitation of input
signal X is selected to result in signal doubling, with AO 2 starting to operate after
control of AO 1.
