SECTION 5: TROUBLESHOOTING
INTRODUCTION
The Troubleshooting Guide on the following pages is
intended to help locate problems within the bill acceptor.
If a bill acceptor cannot be repaired by following this
guide, return the unit to the nearest Coinco Service
Center for repair along with a complete description of the
problem you are having with the bill acceptor.
Logic troubleshooting minimizes the time spent in
removing and replacing parts that are not defective.
Some failures are caused by minor problems such as dirt
or loose/faulty connections. Please check the following
before replacing any parts:
Clean any dirt or dust from the bill path.
Coin changer inventory tubes are filled to their
correct levels.
Connectors are inserted correctly.
Connector pins are not bent or broken.
All wires are properly secured.
MAG50 DIAGNOSTIC CODES
Troubleshooting can be done by reading the number of
flashes or blinks of light from the LED located inside the
logic board cover. These flashes can be seen through the
gray cover.
Diagnostic codes 2, 8, 14, and 18 are not used. Codes 1,
3, 4, 5, 15, 16 may appear during normal servicing of the
MAG50. If the MAG is flashing a #5 code, turn off
power to the MAG for 10 seconds. Reapply power to the
MAG50 and diagnostic codes 6, 7, 9, 10, 11, 12, 13, and
17 will appear for approximately 30 seconds. After 30
seconds these codes will revert back to the #5 code. If
more than one error exists, the lower number code will
appear until its condition is corrected. The left and right
sensors referenced in the next column are given viewing
the MAG50 from the front.
NOTE: With software 67090 and 67126, diagnostic
code #4 (4 flashes) will not appear if all bill accept
switches are off.
