three LED groups. The LEDs are lit according to priority, with red being the highest and green
the lowest priority. For example, if on one panel there is an indication that requires the green
LED to be lit, and on another panel there is an indication that requires the red LED to be lit, the
red LED takes priority and is lit. The LEDs can be configured with PCM600 and the operation
mode can be selected with the LHMI or PCM600.
Information panels for the indication LEDs are shown by pressing the Multipage button.
Pressing that button cycles through the three pages. A lit or un-acknowledged LED is indicated
with a highlight. Such lines can be selected by using the Up/Down arrow buttons. Pressing the
Enter key shows details about the selected LED. Pressing the ESC button exits from
information pop-ups as well as from the LED panel as such.
The Multipage button has a LED. This LED is lit whenever any LED on any panel is lit. If there are
un-acknowledged indication LEDs, then the Multipage LED blinks. To acknowledge LEDs, press
the Clear button to enter the Reset menu (refer to description of this menu for details).
There are two additional LEDs which are next to the control buttons
for example, represent the status of a circuit breaker. The LEDs are controlled by the function
block OPENCLOSE_LED which must be configured to show the status of the breaker.
