magnet allows the acceptance of quarters when
energized. (Refer to 25¢ coin return electro-magnet

DC MOTOR AND GEAR CASE ASSEMBLY
(figure 3-2)
This assembly, located in the lower right corner
in the rear of the changer, consists of a 5000
RPM motor attached to a gear train with an
output of
30 RPM.
a cam attached to the output
shaft of the gear box moves the payout slide
under the coin tubes by means of a driver link.
When the motor runs, the slide pays out change
alternately from the two nickel coin tubes.
K.
MOTOR CARRIER AND PULSE SWITCH
(figure 3-3)
The switch is attached to the bottom of the
gearbox assembly and is actuated by a motor
cam. This switch serves two purposes, first to
complete the motor cycle back to the start
position and secondly, it pulses the logic system
each time a nickel is paid out.
L. I.OW VOLTAGE TRANSFORMER
(figure 3-1)
This transformer assembly is located in the front
upper portion of the coin changer housing behind
the acceptor. It reduces the input line voltage to 18
volts A.C. to power the logic system.
M. THERMAL CUT-OFF
Located behind the transformer is a heat sensitive
device that will open in the event of a shorted
transformer winding. This in turn stops the voltage
to the logic system.
ELECTRONIC LOGIC BOARD
(Figure 3-4, 3-5)
A.
The S75-9800A and 575-98008 logic boards are
directly interchangeable with no modifications
required. The logic boards' inputs are connected to
the three changer coin switches.
At a preset count determined by the sales price
setting, the logic system will energize the vend relay
initiating the vend signal to the vendor.
