3.6.6. LED Functions
Normal Run Time Mode
There are nine tri-colored (green, red, and amber) LEDs on the INFORMA PMD-A front
panel. When the device is on, all nine LEDs keep flashing (anti-clock wise direction) in green
for a maximum of 3 minutes. This indicates that the LCD interface is booting up. If the
firmware is upgrading, then the right side LEDs scroll from top to bottom and the left side
LEDs scroll from bottom to top in green. Once the firmware is upgraded successfully, only
the Health LEDs flash in green and the others are in an OFF state. If a communication
failure occurs during the upgrade, all nine LEDs flash in red.
