Cyclic operation (X001 = OFF, X002 = OFF)
1)
When the start button X000 is pressed, the outputs turn ON in the order "Y000 (wait indication) → Y001 (center
lamp) → Y002 (center fountain) → Y003 (loop line lamp) → Y007 (loop line fountain) → Y000 (wait indication)",
and then the outputs return to the wait status.
Each output is switched in turn every 2 seconds by a timer.
Continuous operation (X001 = ON)

Y001 to Y007 turn ON in turn repeatedly.
Stepping operation (X002 = ON)
