Figure 58: 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 acknowledge for the LED signals is done for all three signals
(RED, YELLOW, GREEN) of the LED.
• A reset of the LLEDs 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.
