6.4 Rectifier Features
6.4.1 Rectifier Front Panel Lights
Refer to the Cordex CXRF 48-1.8 kW manual for further details.
AC LED light
The top LED (green) is on when AC
is within valid 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.
DC LED light
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
controller.

Alarm (ALM) LED light
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 fail.
The LED will flash (~2Hz) when a minor alarm is detect-
ed; 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 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 rec-
tifier, the LED will extinguish if no AC power is present.
