All In uses a linear actuator to raise and lower the playfield when the game is powered on. The actuator is located in the middle of the game on the bottom side of the playfield.
The actuator is driven by 12vdc which is supplied to the main board through the safety switch on the back door of the game. If the back door is open or loose causing it to not close the switch contacts there will be no voltage to drive the actuator, this will also generate and error 11 on the game.
The signal to drive the actuator is sent from the main board connector P5 between pins 2 (orange/black wire) and 5 (black/blue wire) and will be 12vdc when the table is going up and -12vdc when the table is going down.
