Check the BJB board to see if the
green LED is extinguished and the
yellow LED is lit. (Note that if the
BJB has indeed failed, the green and
yellow LEDs on the other basic
boards will also be lit.) If so, perform
the following steps:
1. Press the reset switch on the front
of the BJB circuit pack. If all
diagnostics pass, it is possible that
some type of one-time
abnormality occurred to cause the
failure (such as hot-insertion of
option boards, shorting backplane
pins when installing optional
equipment, etc.)
2. If the diagnostics did not pass, or
if the problem recurs, replace the
BJB circuit board.
3. If the problem remains, put the
original BJB circuit pack back in
the controller. Remove all BJC
rectifier interface boards and the
BJE alarm relay/display board.
Press the reset switch on the BJB.
If the problem is still present,
replace the BJA power board. If
the problem is resolved, insert all
boards that were removed, reset
the controller, and verify proper
operation.
4. If the problem remains, put the
original BJA back in the
controller. Insert all boards that
were removed, resetting the
controller after each board is
installed and looking for improper
operation. Replace the board that
causes the failure, insert the
remaining option boards, and
verify proper operation.
5. If the problem remains, call your
local RTAC representative.
