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; if the
module is unable to source power as a result of any of the following conditions:
Output fuse blown AC Mains Input Fail Module fail (ramp test fail)
High voltage (OVP) shutdown Thermal shutdown Local shutdown
UPF fail No output power Fan (1 and 2) fail.
The LED will flash (~2Hz) when a minor alarm is detected; if the modules output capability has
been reduced or a minor component failure is detected during the following conditions:
VAC meter fail AC foldback Remote equalize
Fan (1 or 2) fail Low output voltage High output voltage
Current limit (programmable option) Power limit (programmable option) High temperature foldback
Temperature sense fail Soft start operation Communications lost.
The LED remains off in the absence of an alarm. If the unit output is not connected to a battery
or parallel rectifier, the LED will extinguish if no AC power is present.
