BC-3500 Bill and Coin Changer
CK COIN DETECTORS
Symptom:
More than one coin detector was blocked while the bill changer was in STANDBY. One of the buckets may have
an incorrect change load, or one of the hopper motors may have been running in standby mode.
Corrective Action:
More than one of the coin photodetector inputs is, or was, giving an incorrect signal.
1. One of the LEDs on the dispenser may have burned out. If any LEDs are out, check the wiring to that LED.
Check the LEDs and replace any defective LEDs.
2. If all LEDs are not lit, check the +5 VDC LED on the power control center. If it is not lit, check the power supply.
If it is lit, check +5V power distribution lines in the harness (Blue wires).
3. Press the FUNCTION button. If the message reappears, check for dirt on the detectors and LEDs. If they are
clean, check the coin photodetectors (per Section 3). If they are OK, check the wiring from the photodetectors
to the CCC for open connections or shorts to Ground. If no problems are found, replace the CCC.
4. If this message does not reappear after resetting the bill changer, check the wiring to the hopper motors and
coin detectors. If no problems are found, replace the CCC. To restore the bill changer to operation, press
the FUNCTION button after correcting the problem.
NOTE:
This error code may be the result of a leaky output to the hopper drive motor from the CCC. If this is
the case, replace the CCC.
