2.3.7 Alarm and Control Output Relays
The CXC contains Form C digital alarm output relays to extend alarms and control external apparatus. Each
internally generated alarm or control signal may be mapped to any one of the relays, or, several signals may be
mapped to just one relay or none at all.
2.3.8 Network Connection and Remote Communications
The Cordex system can be set up, monitored and tested via Ethernet 10/100 Base-T serial data connection. The
communication protocol supports a web interface. All alarming and control of Cordex rectifiers is accomplished
with a CXC via a CAN bus.
A step-by-step connection wizard (Windows® 2000 operating system) – provided to establish remote
communications with your CXC – is available via the Argus website (www.argusdcpower.com).
2.4 Cordex 48-1.8kW Rectifier
Figure 6–Cordex 48-1.8kW modular switched mode rectifier
2.4.1 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.
2.4.1.1 AC
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.
2.4.1.2 DC
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.
2.4.1.3 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 fail.
