Just got a shadow that wasn't working for a good price. I got everything working now except for the wall to the inner sanctum. In the solenoid test menu I can get the wall up and wall down to work. In the switch test menu the wall up switch registers fine. There is no wall down switch that I can find. Thought maybe it was the magnet optos, but they seem to be working fine and the magnet test works fine. I do get an error report on startup that says er.wall target bad. I assume this is my problem, but don't know what it refers to . I have scoured the manual and cant seem to find it. If anyone out there can assist I would sure appreciate it. Thanks
