2.1.1 LEDs
The front panel LEDs provide:
• Rectifier status summary,
• Rectifier software upgrade in progress indication,
• Locate module pattern.
Rectifier status summary will show the rectifier alarm status, communication fail status and rectifier on/off status.
2.1.1.1 AC
ON
The top LED (green) is on when AC is within valid range. The LED will flash (~2Hz) when AC is
outside the nominal range – AC voltage is invalid if the AC Mains Low or AC Mains High
alarm is active. The LED turns off when AC has failed.
2.1.1.2 DC
ON
The middle LED (green) is on when the rectifier is delivering power to the load. The LED will
flash when communication is lost. The LED turns off when the rectifier is off; e.g., when
commanded via the CXC.
2.1.1.3 ALARM
The bottom LED (red) is on continuously in the event of an active Module Fail alarm. The LED
will flash (~2Hz) when a minor alarm is detected. The LED remains off in the absence of an
alarm.
