LED indication function (HL, HLED)
$XWRPDWLF UHVHW
The automatic reset can only be performed for indications defined for re-starting mode
with the latched sequence type 6 (LatchedReset-S). When the automatic reset of the
LEDs has been performed, still persisting indications will be indicated with a steady
light.

The sequences can be of type Follow or Latched. For the Follow type the LED follow
the input signal completely. For the Latched type each LED latches to the correspond-
ing input signal until it is reset.
The figures below show the function of available sequences selectable for each LED
separately. For sequence 1 and 2 (Follow type), the acknowledgment/reset function is
not applicable. Sequence 3 and 4 (Latched type with acknowledgement) are only work-
ing in collecting mode. Sequence 5 is working according to Latched type and collecting
mode while sequence 6 is working according to Latched type and re-starting 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, the indication obtains corresponding color corre-
sponding to the activated input and operates according to the selected sequence dia-
grams below.
In the sequence diagrams the LEDs have the following characteristics:

This sequence follows all the time, with a steady light, the corresponding input signals.
It does not react on acknowledgment or reset. Every LED is independent of the other
LEDs in its operation.
