Figure 6:
The function button and indication LED panels are not visible at the same time. Each panel is
shown by pressing one of the function buttons or the Multipage button. Pressing the ESC
button clears the panel from the display. Both panels have a dynamic width that depends on
the label string length.

LEDs

The LHMI includes three status LEDs above the display: Ready, Start and Trip.
There are 15 programmable indication LEDs on the front of the LHMI. Each LED can indicate
three states with the colors: green, yellow and red. The texts related to each three-color LED
are divided into three panels and can be browsed with the Multipage button.
There are 3 separate panels of LEDs available. The 15 physical three-color LEDs in one LED
group can indicate 45 different signals. Altogether, 135 signals can be indicated since there are
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
LEDs can indicate the status of two arbitrary binary signals by configuring the
OPENCLOSE_LED function block. For instance, OPENCLOSE_LED can be connected to a circuit
breaker to indicate the breaker open/close status on the LEDs.
