and the OUTPUT STATE parameter.
Output OUTPUT 1 : Output 1 is related to the value in the OUTPUT 1 column in the OUTPUT STATE
table. If the value of the angle in the ANGLE input is higher or the same as a value
N in the ANGLE column in the OUTPUT STATE table and less than the value N+1 in
the table, the value of the corresponding OUTPUT 1 column is copied to OUTPUT 1
(1 => output at ON, 0 => output at OFF).
Output OUTPUT 2 : Output 2 is related to the value in the OUTPUT 2 column in the OUTPUT STATE
table. If the value of the angle in the ANGLE input is higher or the same as a value
N in the ANGLE column in the OUTPUT STATE table and less than the value N+1 in
the table, the value of the corresponding OUTPUT 2 column is copied to OUTPUT 2
(1 => output at ON, 0 => output at OFF).
Parameters NUMBER OF DEGREES: Equivalent to the wheel step number (2 to 72 steps of 5° to
180°). \
OUTPUT STATES: Table is listing the output states for each position. These states
can be modified by left-clicking in the corresponding boxes.

Short description
APPLICATION-SPECIFIC FUNCTION: PUMPS MANAGEMENT: (TANK MANAGEMENT WITH CIRCULAR PUMP
CHANGEOVER).
This function is used to set to ON a maximum of four digital outputs which can be activated (OUTPUT 1 ...
OUTPUT 4). This number is equal to the maximum number of digital inputs (from 2 to 4) in the ON state.
In addition, the outputs set to ON are selected so that in the event of prolonged operation, each output
will have been set to ON the same number of times.
The ON duration of the outputs is set to equal values by applying the following technique:
As the number of ON inputs increases, the outputs changing to ON are those following the order of the
PILOT 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
