Card-Edge LEDs
Status LED
The Status LED is located on the front card-edge of the KMV-3901/3911, immediately above
the Select button, and is visible through the front access door of the Densité frame. This
multi-color LED indicates the status of the KMV-3901/3911 by color, and by blinking/steady
illumination:
The Status LED always shows the most severe detected error status that it is configured to
display (see
Alarm Configuration Panel , on page 17), and in the table above error severity
increases from top to bottom, with green representing no error/disabled, and blinking red
the most severe error.
If the Status LED is blinking orange, it means that the card is selected for local control using
the Densité frame’s control panel, or that the card is booting up. See
Using the Densité
Frame Control Panel , on page 11 for details.
