Figure 2-15. Switch Cluster
(1) PINS UP SWITCH
(4) MAGNET
The switches in the cluster include:
(1) Pins Up Switch - This switch indicates when the string wagon is in at the back of the machine
and the pins are in the "up" position.
(2) String Brake Switch (SOL) - This switch is used after pins have been knocked over on a first
ball delivery. In operation, after the string wagon has passed the pins up position, this switch
causes the string brake solenoids inside the PMI (Pin Motion Interface) for those pins that were
knocked over to energize. This keeps the pins from lowering onto the pindeck as the wagon
travels toward the front of the machine.
(3) Home Position Switch - This switch indicates when the string wagon is positioned toward the
front of the machine approximately under the String Limiting Bar and the pins are standing on
the pindeck. This switch causes the motor to shut off after the pins are placed on the pindeck.
