Section 4: Troubleshooting
CK BILL RETRN SW
Symptom:
The bill return switch was closed longer than 10 seconds. This error will disable the bill return function. All other
changer functions continue to operate.
Corrective Action:
1. Remove the bind or jam in the bill return linkage.
2. Check the R/G wire from the bill return to CCC (P5 Pin 9) for a short to ground.
3. Check the bill return switch. If it is defective, replace it. If it is not defective, replace the CCC.
Bill Changer Errors (Shutdown)
Only one of these errors will exist at a time. The display will flash the error code indicating a SHUTDOWN. One of
these errors may also exist with up to three NON-SHUTDOWN errors.
COIN DETECTOR ERRORS WHILE IN THE STANDBY MODE
CK L COIN DETCTR
Symptom:
The left coin detector was blocked while the bill changer was in the STANDBY state. One of the buckets may have
an incorrect change load.
Corrective Action:
The left coin photodetector input is, or was, giving an incorrect signal / or the left hopper may have been running in
standby mode.
1. The left LED on the dispenser may have burned out. If the LED is still out, check the wiring to that LED. Check
the LED and replace it if it is defective.
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 left detector and LED. If they
are clean, check the coin photodetector (per Section 3). If it is OK, check the wiring from the photodetector
to the CCC for an open connection or short to Ground. If no problems are found, replace the CCC.
