The Ball Gate Assembly: Technical Informaon
Two half-moons aached together and connected to a single motor. The posion of the le half-moon is
sensed by two reed switches. A small magnet is located under the le moon. When the reed switch is
acvated, it will be at 0 VDC, the other will be opposite, +5 VDC.
On the main board at J14, pins 1 and 2 supply the voltage to the ball gate motor. Pins 3 and 4 are the sense
lines used to determine the posion of the ball gate. Located underneath the le side of the ball gate is a
magnet. When the gate is closed this magnet acvates the sensor aached to pin 3 taking the signal to
ground. Pin 4 will be at +5 VDC. When the gate opens, pin 4 will go to ground and pin 3 will have +5 VDC on
it.
If the magnet sensors are not ush to the wood surface, the magnet will not acvate the sensor causing the
ball gate to move pass the closed or open posion. When this occurs, the ball gate will shut down and only a
power cycle will allow the ball gate to work again.
If aer checking that the ball gate is not having a sensor problem, look at the linkage for any of the Grubb
screws that might have goen loose. Also look at the connector rod and make sure it is sloed and not
rounded out.
** Note ** If the game doesn’t see the open or close reed switches it will open the ball gate and not
aempt to run the ball gate motor again unl you power cycle the game.
Reed switch embeds into the wood instead of being at the surface.
