This sequence has a latched function and works in collecting mode. Every LED is in-
dependent of the other LEDs in its operation. At the activation of the input signal, the
indication starts flashing. After acknowledgment the indication disappears if the signal
is not present any more. If the signal is still present after acknowledgment it gets a
steady light.
