JCM Part No . 960 - 000076R _ Rev . 1 © 2007, JCM - American Corporation A - 4 Appendix A World Bill Acceptor (WBA® - 1x/2x - SS & SS2) Troubleshooting Performance Tests The WBA is equipped with diagnostic features to aid in repair and maintenance . This portion of Appendix A describes the test procedure for use with each function using DIP Switch settings to identify the cause of a failure condition . In order to identify a failure condition’s cause, the WBA has to be in the TEST mode . To enter the TEST mode perform the following steps: 1 . On the CPU Board set DS1 DIP Switches No . 1 through 7 to “OFF” and Switch No . 8 to “ON” . 2 . Supply the power to the WBA . 3 . Check that the Red diagnostic LED blinks at a steady rate . This condition indicates the unit is now in the TEST mode . 4 . Set the DIP Switches depending on the test you wish to execute according to Table A - 4 through Table A - 12 . 5 . Set DIP Switch No . 8 to “OFF” to start a particular test . When the test begins, the Red diagnostic LED will extinguish (go out) . After few seconds, the Red diagnostic LED will independently turn ON & OFF depend - ing on the test being executed . 6 . To finish a test, set DIP Switch No . 8 to ON again, and turn the WBA power OFF . Choosing and Selecting Operational Tests Set the WBA into the “Test Mode”, and then set the related DIP Switches to match each operational test shown in the following Test Tables . Set DIP Switch 8 to OFF initially to start each test . Auto Calibration Mode The Auto Calibration Mode is entered by turning DS1 DIP Switches 5, 6, 7 and 8, to the “ ON ” position and powering up the unit: •   The unit will cycle once and stop to receive the White and Black reference papers –   Insert the calibration paper black end first •   The unit will sample the White Reference Paper then the Black Reference Paper –   It will do this five (5) or more times and then return the calibration paper . If calibration fails, the Test LED/Bezel Light will start to blink, then pause, blink, then pause, etc . Count the number of blinks in between pauses, this number is the error code count (see the Calibration Error Indication Table below to identify the error) . C ALIBRATION E RROR T ABLE Table A - 4 provides the Calibration Error LED Blink indications . DS1 NOTE: If the WBA - 1X does not enter diagnostic mode (i . e . , The LED is constantly OFF (out) or constantly ON (lit), a CPU problem may exist . Re - flash the unit (if a WBA 10/12/14) or change the EPROM (if a WBA 11/13/15) . NOTE: The setting of DIP Switch 8 to ON again will interrupt a test, and restore the system to the Test Mode . DS1 NOTE: The Test LED on the Power Supply or the Bezel Lamps will blink rapidly if the calibration was successful . NOTE: Use calibration paper part number 501 - 000032 for the WBA - 1X .
