type and collecting mode while Sequence 6 is working according to Latched type and
re-starting (Reset) mode. The letters S and F in the sequence names have the meaning S
= Steady and F = Flash.
At the activation of the input signal to any LED, the indication on the corresponding
LED obtains a color that corresponds to the activated input, and operates according to
the selected sequence diagrams shown below.
In the sequence diagrams the different statuses of the LEDs are shown using the
following symbols:
= No indication
= Green
