Located in the No.1 top sign (access door end of machine), this board drives a sounder to produce
the alarm tone for tilt, motor jam etc.

Pusher Box Motor Control
This system utilises an opto-electronic method to monitor the motor load, and stop the motor in the
event of a restriction/jam.
The motor drive shaft extends some 35mm out of the rear end of the motor case. It is here that the
opto sensor PCB is located, secured to the motor case. The motor shaft has a hole drilled in it,
through which the infrared beam may pass when correctly aligned. With the rotation of the motor
shaft, this results in the beam being continually interrupted, and a resultant string of pulses produced
by the opto receiver.
