a visual check by the attendant ensuring that there is no longer any item causing the obstruction.
Reset of the system is done by depressing the recessed button switch located on the rear of the
machine on the right.
There is an LED on the Motor Control PCB, which indicates the output of the opto-sensor. In
normal operation this will appear to be continuously ON, due to the high repetition rate of the
pulses. This facility may be used to check the operation of the sensors, by manually rotating the
motor shaft and observing the LED. The LED should turn on then off as the hole in the shaft
passes between the sensors. Disconnect the motor 110v mains supply first.
The 20mm fuse on this PCB is to provide over current protection to the solid-state relay/motor
combination.
The other relay (RL1) is used to provide a switching function upon system operation, which is
used for signalling to other circuits for alarm operation etc.

Coin Entry
Each player section has three coin entry chutes. The chutes are designed to reject fraud coins into
a reject tray just inside the door.
This is not a high level of discrimination, but serves well and reliably in this application. Other
than keeping the chutes clear and clean no specific maintenance is required
Coin entry chutes are situated on the front of the machine. The chutes are fixed and require no
maintenance. Twin-opto sensors are fitted to detect coins, and to detect and discourage
fraudulent intent.
The central chute on the pin-perspex is motorised as shown below.

Pusher boxes
The pusher boxes are mounted on two Accuride slide bearings. An annual check to remove any
build up of dust, and a light coat of grease will ensure many years of reliable service.
