JCM Part No . 960 - 000076R _ Rev . 1 © 2007, JCM - American Corporation A - 5 Troubleshooting 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 . 5 Gain Error (White level adjustment error) If the reference paper was loaded correctly, change the Upper Sensor Board 6 Digital/Analog Error If the reference paper was loaded correctly, change the Upper Sensor Board 7 Bar Sensor Error Change the Upper Sensor Board 8 Acceptor Head Removed Check condition of the 20 pin connector that connects head to the CPU Board 9 Magnetic Setting Error Change the Upper Sensor Board 10 Write - in Error Change the Upper Sensor Board 11 Black Level Error Replace the Upper or Lower Sensor board Table A - 4 WBA - 1X Calibration Error Indications (Continued) Number of LED Blinks Description Possible Cause Table A - 5 WBA - 1X/2X Functional Test DIP Switch Settings Test DIP Switch Positions Functional Test No . 8 7 6 5 4 3 2 1 1 E/D * X † Transfer Motor Forward Rotation Test (test light OFF = motor speed OK) 2 E/D X Transfer Motor Reverse Rotation Test (test light OFF = motor speed OK) 3 E/D X Stacker Motor and Pusher Mechanism Test 4 E/D X Acceptor Head/Stacker Test (Use Error Table A - 11 only) 5 E/D X X Acceptor Stacker Test without the head (Use Error Table A - 11 only) 6 E/D X Solenoid Test 7 E/D X Acceptor Head Sensor Test (PH06) 8 E/D X Transport Sensor Test (PH07) 9 E/D X X X Bill Acceptance Test without Cash Box and Frame (Error Table A - 10 or Table A - 12) 10 E/D X X X X Bill Acceptance Test with Cash Box and Frame (Error Table A - 10 or Table A - 12) * .
