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.
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
These 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.
