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
and
. 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.
