During the last replenish cycle, the system detected a coin pulse from the dispenser that
was much longer than normal. Most likely, one of the change buckets has an incorrect
change load.
Are both photodetector LED's lit?
Check the wiring to the LED in
the back of the dispenser.
Replace any unlit LED with the
part indicated in the components
list for the power supply board.
Is the +5VDC LED on the power control center ON?
Refer to the chart
+5VDC FAILURE
+5VDC LED OUT
Is the +5VDC much
brighter than the other
three LED's?
Are the transport
LED's ON?
A defective +5V regulator VR802.
Replace it with the part indicated in
the components list for the power
supply board. See NOTE.
A harness problem exists.
Check continuity from
J203-4 and J202-8 to the
dispenser J402 (Blue and
Black wires).
Unplug J203 from the power
control center. Check for
+5VDC between pins J203-4
and J202-8. Is the voltage
between 4.5VDC and 5.5VDC?
A harness problem exists.
(Blue and Black wires.)
An internal harness
problem. Replace the
power control center.

Press the FUNCTION button. Does the machine go back
into SHUTDOWN?
YES
A new status message
will appear. See the
troubleshooting chart
for the new message.
YES
NO
Check for a restriction in the
upper coin chute that would
hold up coins.
Check the O/BR, O/B, and O/G
wires from the CCC to the
photodetector for an intermittent
open circuit.
IF OK
A defective CCC. Replace with
a new CCC.
OR
IF ALL 3 LED'S ARE OUT
NOTE:
Make sure the change load in the buckets is
correct before restoring the machine to service.
If the +5 VDC LED is much brighter than the
others, due to VR802 being defective, the
transport cell LEDs, display LEDs, and pho-
todetector LEDs could be burned out.
Testing the coin detectors with objects other
than actual coins (using your fingers, scales,
metal strips, etc.) may cause the machine to
shutdown with this fault message showing.
