Usually there is a pull rope near where the door connects to the drive mechanism. This rope releases the door from the drive allowing it to opened and closed manually during a black out. Remember to put the door back in the same position when power is restored to re latch it
You have to make sure the trolley on the drive engages with the catch on the door. You may have to lift the door to the point it will engage while you are running the trolley in the close mode. Check that the trolley latch is open and ready to engage the catch. There is usually a rope to pull on to do this.
There are two possibilities here. First is if the main light flashes 10 times when the door reverses it is a door sensor problem. Make sure the sensors are pointed at one another and the small light on each one is lit and not flickering. Tweak them a little. If you cannot get both lights to come on you have bad sensors.
Second is if the door is reversing when it hits the floor. This is a problem with the door traveling too far in the down direction. Locate the 'down limit' located on the side of the motor unit and turn it a bit in the opposite direction of the arrow printed on the cover. Some tweaking may be necessary.
To release the door with the rope - pull straight down and then pull the rope in the direction away from the door. This should lock the mechanism in the open position. To release this pull straight down and release.
Release the door from the opener by pulling down on the rope. It will be very hard to pull. This should release the tension on the chain but I think you need professional help with this opener. It sounds like it is badly out of adjustment. The chain coming off is an indication of a worn bearing that will have to be replaced.
To make sure the trolley will engage properly pull straight down on the rope and release. Then you can either run the opener or move the door by hand. One way or the other it should connect for you.
