World Bill Acceptor (WBA®-1x/2x -SS & SS2)
Appendix A
Diagnostic Test Mode
To enter the Diagnostic Test Mode perform the
following steps:
1. Set DS1 DIP Switch No. 8 on the CPU
Board to
“
ON
”
and DIP Switches 1 thorough
7 to
“
OFF
”
.
2. Apply power and observe that one of the
following conditions occur:
• The test LED/Bezel light blinks at a steady
rate, indicating diagnostic mode is active
• The WBA-1X does not enter diagnostic mode
• The LED is constantly OFF (out) or ON (lit)
–
A CPU problem exists [Re-flash the unit
(WBA 10/12/14) or change the EPROM
(WBA 11/13/15)].
Functional Tests
Table A-5 provides a DIP Switch settings chart for
performing WBA-1X Functional Tests.
Head Sensor Test (PH06)
Perform the following steps to enter the Head
Sensor Test:
1. Enter diagnostic mode – DIP Switch No. 8,
to
“
ON
”
.
2. Apply power to the WBA Unit.
3. Turn DIP Switch No. 6,
“
ON
”
and turn DIP
Switch No. 8,
“
OFF
”.
This activates the Head
Sensor Test. DIP Switch No. 6 will now be
used as the Enable/Disable function switch
for these tests.
