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).

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.
