2.3 CXCM1 Controller
Details of the controller operation are provided in the software manual.
The controller is mounted in the rectifier system shelf and controls the rectifiers. The controller includes software
that does the following:
•
Direct communication with the rectifiers.
• Battery temperature compensation charging.
• Battery performance diagnostics.
• Local and remote communications.
• User definable alarms.
• Daily logging of power system events and system statistics.
The motherboard is located behind the controller’s front panel. The motherboard contains a microprocessor,
memory chips, and many other electronic components.
The controller includes a web server that provides easy set up and monitoring over an Internet connection to a
web browser.
The data-logging feature allows the user to automatically collect data from multiple sources. The collected data
can be AC/DC voltages, load/battery currents, cell voltages, and temperatures. Up to 16 user-defined logs are
available. Typical applications for the collected data include power system details, thermal performance of
outdoor enclosures, battery cell specifics, or power input variations captured by an AC voltage watchdog.
A built-in audio speaker sounds an intermittent tone during active alarms.
