SCF Controller Basic Controller
BJA (power board): If no problem exists, the green LED is lit.
BJB (microprocessor board): After power up, or after a reset, the
green and amber LEDs will both be lit while self diagnostics are in
progress (which will take about 10 seconds). If all diagnostics pass, the
amber LED will extinguish and the green LED will remain lit. If failures
are detected during diagnostics the green LED will extinguish, and the
amber LED will remain lit. During normal operation if a failure occurs
the green LED will extinguish and the amber LED will light.
Other Basic Boards: The basic controller boards (rectifier interface,
alarm relay/display, and power) are diagnosed by the basic controller's
microprocessor. During normal operation, each board’s green LED is
lit. Note that if the basic controller microprocessor board fails, both the
green and amber LEDs on the other basic controller boards will be lit.
Intelligent Controller
BJJ (power board): If no problem exists, the green LED is lit.
BJH (microprocessor board): After power up, or after a reset, the
green and amber LEDs will both be lit while self diagnostics are in
progress (which will take about 30 seconds). If all diagnostics pass, the
amber LED will extinguish and the green LED will remain lit. If failures
are detected during diagnostics the green LED will extinguish, and the
amber LED will remain lit.
Intelligent Option Boards: The intelligent option boards (modem, data
switch, and peripheral monitor) are diagnosed by the microprocessor.
During normal operation, each board’s green LED is lit.
