13.4.2 Event History Log
This key sequence prints the entire Event History Log of the UPS at the time the data is requested. The printout begins with the oldest alarm entry in the queue and ends with the most recent. Any alarms that occur while the Event History Log is printing are included in chronological order.
The Event History Log lists up to 500 system events in chronological order with the most recent event listed last. Figure
In this mode, system events are continually logged through the serial port to the device connected to the port.
The printed log entries contain a time and date stamp and the alarm text message. Terminal mode uses this format for printing alarm entries:
