CREDIT AND ACCUMULATION
See Figure 7
There are two sensors, one in the separation section
of the acceptor and one in the cash box path of the
acceptor. As coins pass either one of these sensors,
the changer sends credit information to the vendor
electronic controller where the coin credit is
accumulated.
VEND
Vend is a function of the vendor electronic
controller. The vendor controller accumulates all
credit information received from the coin changer.
As credit is accumulated in the vendor controller,
vend selections can be made when their respective
vend price settings are equalled.
COIN PAYOUT
Coins are paid out from the coin changer when a
change payback is required or when either of the
coin changer inventory switches are manually
operated. Coins are dispensed by D.C. solenoid-
operated slides located at the bottom of each of the
three coin tubes. The payout solenoids are controlled
by signals generated by the vendor controller or the
three inventory switches.
When a solenoid energizes, the upward motion of its
plunger compresses a spring and draws the solenoid
lever, which in turn pushes a payout slide forward.
This loads the coin for payout. When the solenoid
de-energizes, the spring force returns the plunger to
its de-energized state, which returns the solenoid
lever and payout slide, dispensing a coin. Coin
payout rate is determined by the vendor electronic
controller board.
Inventory Switches
Located on the front of the coin changer is a nickel,
dime and quarter inventory switch. These switches
are used to manually remove coins from the changer
coin tubes. They are disable while the vendor is in a
vend cycle.
