OUTPUT NUMBER: 1 for OUTPUT 1, 2 for OUTPUT 2, 3 for OUTPUT 3 and 4 for OUTPUT 4. For example, if the
"outputs controlled" parameter has the value 4, if PILOT OUTPUT NUMBER has the value 3 and just one input
is set to ON, only the OUTPUT 3 output will be set to ON. As soon as two inputs change to ON, the OUTPUT
3 output remains at ON and the OUTPUT 4 output changes to ON. As soon as a third input changes to ON, the
OUTPUT 3 and OUTPUT 4 outputs remain ON and OUTPUT 1 changes to ON.
As soon as the number of outputs decreases, the outputs changing to OFF will be those which have been in
the ON state the longest. As soon as one output changes to OFF, PILOT OUTPUT NUMBER takes the value of
the output number after the output(s) which has (have) just been set to OFF. To complete
the above example,
as soon as one input changes to OFF, the OUTPUT 3 output changes to OFF and PILOT OUTPUT NUMBER displays the
integer value 4.
The Parameters tab in the property box contains the number of outputs which may change to ON depending
on the number of inputs which are set to ON. The values of this parameter are fixed at 2, 3 or 4.
If the value of the parameter is fixed at 2, only the OUTPUT 1 and OUTPUT 2 outputs are used and may
therefore change to ON. In this case, if more than two inputs change to ON, the OUTPUT 1 and OUTPUT 2
outputs remain at ON and the OUTPUT 3 and OUTPUT 4 outputs remain fixed at OFF.
If the value of the parameter is fixed at 3, only the OUTPUT 1, OUTPUT 2 and OUTPUT 3 outputs are used and
may therefore change to ON. . In this case, if four inputs change to ON, the OUTPUT 2, OUTPUT 2 and OUTPUT
3 outputs remain at ON and OUTPUT 4 remains fixed at OFF.
If the value of the parameter is fixed at 4, only the OUTPUT 1, OUTPUT 2, OUTPUT 3 and OUTPUT 4 outputs
are used and may therefore change to ON.
All inputs which are not connected have the value OFF.
When the program is initialized, PILOT OUTPUT NUMBER is fixed at 1.
The Parameters tab contains the default check box which re-initializes PILOT OUTPUT NUMBER to 1 (and
defines the first output activated when the first input changes to 1) after a controller power failure.
Example of use:
Filling a tank with a group of four pumps operating in parallel. The operating duration of each pump is the
same.
