○: With function △: Backup at intervals of 5 min and alarm history only.
Model KM1 has a data logging function. Log data is divided into the three types: data that is backed
up every 5 min, data that is backed up at arbitrary timing (5 min, 10 min, 30 min, 1 hour, 2 hours, 6
hours, 12 hours, or 24 hours), and alarm history that is backed up when an alarm is generated.
1) Data that is backed up every 5 min
This data includes the following items.
Total active power consumption, total regenerated energy, and total reactive power
2) Data that can be saved as log data at arbitrary timings
Log data is saved in conjunction with the time of the main body.
For the items, refer to "List of log data to be saved" on Page A-18.
3) Alarm history
Histories of alarms generated in the past can be confirmed via communication.
Data is saved every 5 min.
For details, refer to Page 3-21.
