MAG TROUBLESHOOTING GUIDE

This Troubleshooting Guide 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 American Changer or 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.

MAG 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. Since the red

LED is normally ON, the number of flashes is the

number of times it blinks OFF. These flashes can

be seen on the side of the logic box.

Diagnostic codes 2, 8, 14, and 18 are not used.

Codes 1, 3, 4, 5, 15, and 16 may appear during

normal servicing of the MAG. If the MAG is

flashing a #5 code, turn off power to the MAG for

10 seconds. Reapply power to the MAG 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 code descriptions are given viewing the MAG

from the front.
