Section 1: System Description

DOLLARS ACCEPTED COUNTER
The dollars accepted counter registers the number of dollars accepted by the machine. The counter increments once
for each dollar. (For example: A $5 bill will make the counter increment five times.) This counter is not resettable.
POWER SUPPLY
The
ON/OFF
switch controls power to the machine.
A 7-amp circuit breaker is in the power line to the bill changer. The power transformer is protected by a 2-amp circuit
breaker in the primary winding. A 7-amp and a 5-amp circuit breaker protect the secondary windings.
The power supply circuit board rectifies and filters the 36 VAC and 22 VAC to provide 40 VDC, 30 VDC (current
limited), 12 VDC, 8 VDC, and 5 VDC to the rest of the system. It contains indicator LED’s for the 40 VDC, 30
VDC, 12 VDC, and 5 VDC supplies. Note that the 12 VDC actually runs at about 14.6 V – this is normal.
TEST SWITCHES
The three
TEST
switches are used to manually initiate a change dispense cycle for each of the machine’s escrow
buckets. The computer will not recognize a
TEST
switch closure if the machine is in the process of validating a bill,
dispensing change, or in
SHUTDOWN
. Pushing a
TEST
switch will also cause the stacker to cycle.
POWER CONTROL RELAY
The power control relay switches the 40 VDC, 30 VDC, and 120 VAC supplies to the machine and 5 VDC to the
OUT OF SERVICE
lamp. This relay is controlled by the CCC and is energized under normal operating conditions.
Under
OUT OF SERVICE
conditions, the CCC de-energizes the relay to disconnect the previously mentioned
voltages from the rest of the system and shut down the machine. In this condition, the +40 VDC LED on the power
supply board will be
OFF
, while the other three remain
ON
.
