Universal Bill Acceptor (UBA-1x-SS & x4-SS-SU)
Appendix A
Performance Tests
The UBA 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 UBA has to
be in the TEST mode.
To enter the TEST mode perform the following
steps:
1. Set DIP Switch No. 8 to ON and supply the
power to the UBA.
2. Check that both the Red and Green diagnos-
tic LEDs are lit. This condition indicates the
unit is now in the TEST mode.
3. Set the DIP Switches depending on the test
you wish to execute.
4. Set DIP Switch No. 8 to OFF to start a par-
ticular test. When the test begins, both the
Red and Green diagnostic LEDs will extin-
guish (go out) After few seconds, the diag-
nostic LEDs will independently turn ON &
OFF depending on the test being executed.
5. To finish a test, set DIP Switch No. 8 to ON
again, and turn the UBA power OFF.
Choosing and Selecting Operational
Tests
Set the UBA into the “Test Mode”, and then set the
DIP Switches to match each operational test shown
in the following Test Tables. Set DIP Switch 8 to
OFF initially to start each test.
No. 1 Transport Motor Forward/Reverse
Rotation Test
The tests listed in Table A-4 detect the for-
ward and reverse rotational motor speed.
Confirm that the motor operates smoothly
without emitting abnormal noise.
NOTE: The setting of DIP Switch 8 to ON
again will interrupt a test, and restore the
system to the Test Mode.

The Transport Motor Speed Encoder Sensor does not detect
motor rotation. Check that all harness connectors are seated. A
Motor or CPU Board failure may have occurred. Exchange the
Motor/CPU Board with a known good board. Refer to Section 4
regarding Circuit Board Removal.
DIP Switch Block Settings
If diagnostic LED status is different from
the Table A-4 listed states, contact JCM
Technical Support.
No. 2 Stacker Test
The tests listed in Table A-5 detect the Bill
Stacker’s operational condition. When the
test starts, the pushing mechanism will
begin operating constantly.
When the Green LED lights, it indicates
the Stacker is working properly.
If the Red LED flashes, refer to the
Stacker Test Error Conditions listed in
Table A-5 to discover the probable error
condition.
