When more than one color is used the rules for priority are valid. Two basic
principles are:
•
Two or more signals are still
ON
when the LED is acknowledged.
•
All colors (signals) are acknowledged and they will illuminate in steady
state.
•
Incoming additional signals with lower priority will illuminate when
they become the highest priority in steady mode.
•
One or more signals with higher priority are changing to
ON
after an
acknowledgement.
•
The higher priority color (signal) will illuminate in flash mode.
