4. Features
4.1 3.0kW Rectifier
4.1.1 Front Panel LEDs
The front panel LEDs indicate the rectifier status summary and patterned response to Locate Module command.
ALARM / FAULT (1)
The red LED is on during an active Module Fail alarm if the module is unable to source power due to a fault condi-
tion. Refer to the relevant controller manual for fault details.
The LED flashes (~2Hz) when a minor alarm is detected if the modules output capability has been reduced or a
minor failure is detected.
DC ON (2)
The green LED is on when the rectifier is delivering power to the load. The LED goes out when the rectifier is off. For
example, when commanded by the CXC.
AC ON (3)
The green LED is on when the AC input voltage is qualified and within the specified range 85Vac to 310Vac and
frequency 45 to 65 Hz.
LED Activity During the Locate Module Command from CXC
The Locate Module command from the CXC, causes the LEDs of the target rectifier to flash in a cyclical pattern.
This flashing normally lasts 60 seconds.
LED Activity During Power Save
When a rectifier is put into power save mode, only the AC ON LED remains illuminated.
NOTE:
The red LED will remain active if the module is receiving power from the DC bus.
