Fluorescent Lighting
WARNING – Dangerous Voltages (115v) - switch OFF prior to replacing!
Fluorescent tube lighting is situated in the top sign area, with the attendant gear tray. A second
gear tray provides for the coin entry lighting. The tilt board is located in the 110v Power Box
(Section 4.7), and this interrupts the electrical supply to the Top Sign Fluorescent lamps in the
event of a tilt or tamper condition.
5.2
Dichroic Lighting
Low voltage dichroic spot lamp lighting is situated at the top of each playfield. These lamps are
easily replaced by simply pulling the old bulb free from the fitting, and pushing the replacement
bulb back in place. These lamps are rated at 35W, and should only be replaced with a similarly
rated lamp.
WARNING - These lamps become very hot in operation - allow to cool before handling!

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
through, which conduits the infra-red beam 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.
