Dagu T'Rex Motor controller issues

I just started out to build a 6WD using the Wild thumper and Dagu’s T’Rex Motor Controller. I got a new T’Rex from Dagu.

When I plugged the board through USB to my laptop, I see both the Motor fault LEDs brightly lit along with the power led.

I am not sure whether the board is faulty or not. Is there any way I can figure out if everything is fine or not? I haven’t powered the motors yet. I just was looking to download the code to the board so connected it through USB.

Appreciate your comments!
