6.4.2 Basic Operation

The solenoid plunger is mechanically linked to the coin diverter in the coin chute
assembly. When no power is applied to the solenoid, the plunger is extended and
valid coins fall into the hopper. When 24 V DC is applied to the solenoid, the
plunger retracts, causing the diverter to redirect valid coins to the cash box. A tab at
the lower end of the plunger interrupts the beam in the photo-optic sensor when the
plunger is fully extended.
In this way, the machine software can indirectly monitor the destination of accepted
coins by monitoring the position of the diverter. If the machine software detects that
the diverter optic state does not correspond to the intended diverter position the
machine locks up with the fault message COIN DIVERTER FAULT. The diverter
changes position only at the end of a game.
