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 con-
dition. 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 HP.
AC ON (3)
The green LED is on when the AC input voltage is qualified and within the specified range 90Vac to 310Vac and
frequency 44 to 66 Hz.
LED Activity During the Locate Module Command from CXC HP
The Locate Module command from the CXC HP, causes the LEDs of the target rectifier to flash in a cyclical pat-
tern. 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.
