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.
