Controller LEDs

Do-more controllers in the DL205 series have two-color LEDs that are used to visually provide operational status to the user.

Each of the LEDs can be either RED, GREEN, or YELLOW. The LEDs can be ON continuously or blinking This gives the controller many options for color combinations and blink patterns that can indicate different operational modes, and fault conditions, and provide diagnostic information and communication status.

H2-DM1E LED Pattern Descriptions

In addition to the individual definition of each LED, there are times when the controllers will use combinations of LED ON/OFF state and colors to convey status information. The following combinations use some or all of the LEDs:

ERR LED is blinking RED for (15 seconds) Do-more Designer can blink the ERR led for 15 seconds to verify that a communication link is targeting the correct controller

All eight (8) of the LEDs are ON and the color of each LED is YELLOW indicates the boot loader has started running

All eight (8) of the LEDs are ON and the color of each LED is GREEN indicates the operating system has started running

All eight (8) of the LEDs are cycling through RED & GREEN, in a circular 'chase' pattern indicates the operating system is initializing

The left-most four (4) LEDs are cycling through RED & GREEN, in a 'bouncing ball' pattern indicates the controller is running only the boot loader and is NOT going to load and run the operating system. The most likely cause is having DIP switch #1 in the ON position.

All eight (8) of the LEDs are ON and the color of each LED is RED indicates the hardware watchdog timer has expired because the controller's operating system has stopped running.
