3.2.4 Temperature Inputs
Two temperature input channels, T1 and T2, provide monitoring of battery temperature and temperature
compensation (temp comp) or room/ambient temperature. A voltage is supplied to these terminals to power the
temperature sensors.
3.3 Digital Input Channels
The CXCM can accommodate up to three channels and can monitor digital alarm/control signals from rectifiers,
converters and many other types of equipment.
3.4 Alarm and Control Output Relays
The CXCM contains eight 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.
3.4.1 LVD Control (External Option)
The LVD Control functions can be hardwired directly from the assigned relay output to an optional LVD override
control and distribution alarm card. This provides a safety measure to protect against load disconnect during
CXCM reset or replacement; e.g. when the controller is off-line. Operators may also perform test and
maintenance procedures on the CXCM without disturbing the load.
3.5 System Fail Alarm/Relay
The CXCM system fail alarm (K0) activates because of a major internal failure. During such a condition, the unit
will attempt to reset, but if this fails, an alarm condition will be extended to a relay and the red LED on the front
panel will illuminate. This is a fail-safe signal to the remote monitoring equipment; i.e. alarm will be extended even
if power to the unit is interrupted.
3.6 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 – provided to establish remote communications with your CXC – is available via
the Argus website (www.argusdcpower.com).
