•
From function input
•
The active indications can also be acknowledged/reset from an input,
ACK_RST, to the function. This input can for example be configured to a
binary input operated from an external push button. The function is positive
edge triggered, not level triggered. This means that even if the button is
continuously pressed, the acknowledgment/reset only affects indications
active at the moment when the button is first pressed.
•
Automatic reset
•
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.
Operating sequence
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
corresponding 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
working 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
corresponding to the activated input and operates according to the selected sequence
diagrams below.
In the sequence diagrams the LEDs have the following characteristics:
= No indication
= Steady light
= Flash
G
= Green
Y
= Yellow
R
= Red

Symbols used in the sequence diagrams
Sequence 1
(Follow-S)
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.
