EX2Ultra not responding after changing sleep settings

Hi, I updated the EX2Ultra settings to put the drive to sleep at night (Made the circles black for the hours i wanted it to go to sleep; hope it is not the other way round). Now i find that the top blue light keeps blinking and then turns red and I am unable to connect to the drive. Please share resolution.

Thanks in advance
