Functional Description of the Series AC2002/2002.1 Changer
To follow along with this walk-through of your changer, fill the hoppers with coins and turn the changer on.
1.
When power is applied, the validator will cycle twice; the out-of-service LED flashes, then goes out; the
green LED on the main logic board comes on steady; and the decimal point on the main logic board
number display will flicker on once per second in the standby mode.
2.
During the power-up mode, the main logic board relay clicks twice, enabling power (120VAC) to the
validator. When this relay is not enabled, it routes 12VDC ground to the out-of-service LED. With no
power to the validator, the changer cannot accept bills. Since it is not in the error mode, the red LED on
the validator logic board is on steady.
3.
When a bill is inserted into the validator bill slot, the bill will be pulled inside. The validator then compares
what the bill looks like to its memory. After the bill is validated, it grounds the 5VDC lines, causing a pulse
along the yellow and blue validator harness wires to pins 5 and 15 of the main logic board. Each pulse
stands for the amount of the denomination validated (i.e., 1 pulse for $1, 5 pulses for $5).
4.
The 5VDC pulse then travels from pins 5 and 15 to the EEPROM chip (ver. DBCG-1”) pin #25. The EPROM
sends a 12VDC pulse to the meter chip (U5) out pins #21 and 22 (one pulse per denomination validated).
5.
The EEPROM also multiplies the bill pulse by the dip switch settings. (The EEPROM reads the dip switch
settings during the power-up mode and stores them into memory.)
