2.14.3 Data Logging
This feature of the CXC web interface allows the user to perform complex/custom configurations of the
data gathered by the Alpha controller. Various ways of setting the log frequency/limit and start/stop trig-
gers enables greater management of the events for collection.
The data is stored in files showing the records associated with each for easy archiving and retrieval. File
Save Option enables a FIFO (first in first out) or “Stop when full” means of data collection.
Recommended size is up to seven signals and a maximum one thousand entries, as very large log files
may not be viewable. If the datalog screen comes up blank, the log is too large to be displayed.

2.14.4 Event Log
The CXC can record up to 500 events. Each unique event is stamped with the date and time. Multiple
events are time stamped for the first daily occurrence and then the accumulated total is shown at the last
daily occurrence of the event. Refer to Relay 7 in the following event log.
Some of the events include the following:
• All alarm events (activation and deactivation).
• Rectifier alarm details.
• Any change of state of the digital inputs.
• Other miscellaneous events; such as, rectifiers being turned off or on due to the Power Save feature.
Once the maximum number of events have been recorded, the oldest events are erased as new events
are added.
