Function block GRP1_LED1 to GRP3_LED15
• The 15 LEDs on the right side of the LCD can indicate in total 45 alarms, warnings or other
signals to the operator. They are organized in three groups 1 to 3.
• Each signal group belongs to one function block.
• Each LED illuminates in one of the three colors: RED, YELLOW or GREEN.
• The organization of flashing, acknowledgment and group selection is done directly between
the function blocks and the basic LHMI keys, the 'Multifunction' key [a] to toggle between the
three groups or the 'Clear' key [b] to acknowledge or reset the LEDs.
• Only the programming of the signals is needed for the LEDs.
• The operation mode of the LEDs is defined in Parameter Setting tool.
