Rectifier Features
2.1
Front Panel
Figure 2–Cordex 24-3.1kW modular switched mode rectifier (shown with optional charcoal finish)
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.
