Check the BSJ board to see
if the green LED is
extinguished and the yellow
LED is lit. If so, perform
the following steps:
1. Press the SW201 reset
switch on the top of the
BSJ board. (This circuit
has an automatic restart,
which will try three
times to restart the
microprocessor.)
2. If the diagnostics did not
pass, or if the problem
recurs, remove all the
optional circuit board
cables, then press the
reset switch on the top of
the BSJ board again. If
all the diagnostics pass,
install optional circuit
board cables one at a
time, verifying operation
after each.
3. If the diagnostics did not
pass, replace the BSJ
board and verify the
failure is resolved. If so,
reinstall the optional
circuit boards and cables
one at a time.
4. If the problem is not
corrected, call your local
RTAC representative.
