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.
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
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.
