Operation:
The current flowing to the projector is monitored by the circuit.
When this current increases beyond a certain level such as when the lamp is illuminated, the circuit will output power to the DOWN motor of the screen.
This output will remain on for 2 minutes to allow plenty of time for the screen to reach its down limit.
Thirty seconds after the projector has been switched on, the auxiliary relay will also operate which can be used to turn off house lights via a suitable dimmer or control system.
When the projector is turned off and after a short delay, the UP output will become powered to drive the screen back up and
also the auxiliary relay will change state to turn on house lights if connected.
