No. 7 General Sensor Test
The tests listed in Table A-10 detect the
UBA's Sensors operational conditions.
To check the various sensor conditions, set
the DIP Switches according to the sensor
test desired and observe the LED illumi-
nating conditions for the selected test
listed in Table A-10.
Begin sensor testing as follows:
1. Set the UBA into the "Test Mode", by
switching DIP Switch No. 8 to ON
and applying power to the UBA.
NOTE: If the diagnostic LED illuminating
condition results are different from those
listed in Table A-10 a fault condition is
indicated.
