LHMI: Function key operation mode
The LEDs have a number of different operation modes, see
•
General definitions
•
Each LED can illuminate in one of three colors: RED, YELLOW,
GREEN.
•
Only one color is illuminated at a time.
•
The priority for illumination and the color is linked.
•
Prio 1 = RED
•
Prio 2 = YELLOW
•
Prio 3 = GREEN
•
When RED and YELLOW are ON at the same time, the LED will
illuminate in RED.
•
The operator's acknowledgement for the LED signals is done for all three
signals (RED, YELLOW, GREEN) of the LED.
•
A reset of the LEDs operates also on all three signals of the LEDs.
•
Follow-S
•
The LED illumination follows the status of the signal. The LED
illuminates steady (S).
•
Follow-F
•
The LED illumination follows the status of the signal. The LED
illuminates flashing (F).
•
LatchedAck-F-S
•
The LED latches the signal change OFF-ON and flashes (F) until it is
acknowledged.
•
When the signal is still ON at the time the signal is acknowledged, the
LED changes to steady (S) mode.
•
When the signal has already changed to OFF before the time it is
acknowledged, the LED turns to OFF.
