Using The SkyRoof Controller with a photo sensor will prevent an OPEN or CLOSE
signal, from being sent to the Garage Door or Gate Opener, when the telescope is in the unparked (unsafe) position. However, if the manual GD/G button is pushed, a wireless remote or stray opener signal sent,....THE ROOF WILL MOVE!
This will occur, because we do not control the INTERNAL GD/G Opener signal logic, circuits or relays that operate the GD/G Motors.
For this reason, it is mandatory to have a second level of safety to prevent OPENER INITIATED ROOF MOVEMENT. There are two ways to do this-
> One, is to simply use the existing GD/G Opener Sensors to also detect the parked or unparked telescope position.
> The other method would use the Motor Power Interrupt Unit, that cuts off all power to the GD/G Opener when the telescope is unparked.
