8.7 Auxiliary Board LEDs
1. DL 11 (relay 1) / DL12 (relay 2), will come on (green) when the relay is energized.
2. DL 7 (Channel 1) green
DL 8 (Channel 2) green
DL 9 (Channel 3) green

When device detection occurs, these four (4) LED lights will come on in sequence. This shows that
power is applied to each of the channels on the barrier. When devices are sensed on a channel its LED
will remain on. When a device is not sensed on a channel, its LED will go off. Device detection occurs
when power is applied to the console, the software is updated or device detection is started.
3. DL 4 (green): This LED will flash when the firmware on the auxiliary board operates. When the
software is updated the light will first stay on and then it will flash.
4. DL 5 (yellow): This LED will flash when communication between the auxiliary board and the console
mainboard is occurs. When there is no communication for more than 30 secs, the LED will stay on.
During a software update the LED will go off.
