The Event log table keeps a record of changes to the state of the system to help with troubleshooting.
The types of state changes that are logged include:
• Alarm states
• Configuration changes
• Battery Mode changes (for example, discharging)
To view the Event log, go to Logs > Events and Alerts .
Events are stored in a ‘first in first out’ (FIFO) buffer holds up to 3000 events. Of the most recent events,
up to 25 can be viewed on the LCD, and up to 300 can be viewed via the web. From the web interface,
all 3000 events can be exported as a .csv file.
To export an Event log go to
Logs > Events and Alerts , and press the Export button at the top of the
Event table.
Module Alerts
The Modules Alerts log table tracks what is happening on individual modules without interfering with
Alarms or the Event log.
10.4.2 Battery Log
The Battery log records the duration and change in capacity (A-h) for every charge and discharge of a
battery. If you have Battery Runtime and Heath enabled, the log will also record the change in State
of Charge (SOC) and State of Health (SOH).
Because of the large quantity of information that can be collected for battery charges and discharges,
a complete dataset can only to obtained by exporting the log. The following three figures provide exam -
ples of the data.
When viewed on the LCD, the log shows time, activity type, duration and amp hours delivered.
When viewed on the web, the log includes the battery ID, battery capacity, state of charge, state of
health and the activity results.
When exported to a .csv file, the log includes the Peukert exponent, starting and ending voltages plus
the minimum, maximum and average battery currents and temperatures.
