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.
