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.
MAIN LOGIC BOARD
The main logic board is responsible for all logic
functions of the changer. It receives information
from other changer modules as well as the vending
machine, and based on this information, controls the
operation of the changer.
The main logic board also contains the changer
power supply. It receives the incoming AC voltage
from the vendor and does the following: First, it is
rectified to a DC voltage for the payout solenoids.
Second, it is routed to the transformer’s primary
where it is reduced to 12 VAC. This 12 VAC is
routed back to the logic board where it is rectified
and filtered to the operating DC voltage.
COIN TUBE SENSING
See figure 8
The low tube sensors in each coin tube continually
report the (blocked/not blocked) coin level to the
microprocessor. This information is used to
determine the availability of change for change
payback, escrow and exact change condition.
The full tube sensors in each coin tube continually
report the (full/not full) status to the coin changer’s
microprocessor. The information is then used to
determine the placement of the next accepted coin.
This information controls the action of the acceptor
coin tube and cash box gates.
EXAMPLE: If the quarter coin tube is full (full
sensors blocked by coins) the acceptor coin tube
gate will remain closed and the cash box gate will
open each time a quarter is accepted, routing all
quarters to the vendor cash box via the changer coin
chute. After one or more quarters is paid out as
change, leaving the full sensor exposed (quarter tube
not full), the acceptor coin tube gate will open each
time a quarter is accepted, routing quarters to the
changer coin tube until it is full again.
