1. when any one of first 16 inputs signals (INPUT1 to INPUT16) has logical value 1
the first output signal (OUTPUT1) will get logical value 1.
2. when any one of second 16 inputs signals (INPUT17 to INPUT32) has logical
value 1 the second output signal (OUTPUT2) will get logical value 1.
3. when any one of all 32 input signals (INPUT1 to INPUT32) has logical value 1
the third output signal (OUTPUT3) will get logical value 1.
By use of the settings ModeOutput1, ModeOutput2, ModeOutput3, PulseTime,
OnDelay and OffDelay the behavior of each output can be customized. The OnDelay is
always active and will delay the input to output transition by the set time. The
ModeOutput for respective output decides whether the output shall be steady with an
drop-off delay as set by OffDelay or if it shall give a pulse with duration set by
PulseTime. Note that for pulsed operation and that the inputs are connected in an OR-
function, a new pulse will only be given on the output if all related inputs are reset and
then one is activated again. For steady operation the OffDelay will pickup when all
related inputs have reset. Detailed logical diagram is shown in figure
