Section 3: Pinsetter Electronics
Switch Cluster Switches
The pinsetter uses a 3-phase motor and V-belt to run the string wagon drive gear and shaft. A cam and
switch cluster located at the opposite end of the drive shaft determines the location of the string wagon
by monitoring the rotation of the shaft. Refer to Figure 3-30.
Figure 3-30. Switch Cluster
(1) PINS UP SWITCH (2) STRING BRAKE SWITCH (3) HOME POSITION SWITCH
(4) MAGNET
The switches in the cluster include:
(1) Pins Up Switch - This switch indicates when the string wagon in at the back of the machine
and the pins are in the “up” position. Used only for string tension adjustment.
(2) String Brake Switch - 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 in at the front of the
machine and the pins are sitting on the pindeck. This switch caused the motor to shut off after
setting the pins onto the pindeck.
