3.2.1 Display Alarm History (Fn000)
You can use this utility function to display a history of up to the last 10
alarms.
You can check the alarm numbers and time stamps of the alarms that
have occurred.
A time stamp gives the total operation time to the point at which the
alarm occurred in increments of 100 ms from when the control power
supply and main circuit power supply were turned ON. The total operat-
ing time is recorded continuously for approximately 13 years.
Preparations
No preparations are required.
Time Stamp Display Example
If 36000 is displayed,
3,600,000 ms = 3,600 s = 60 min = 1 h
Therefore, the total operating time in hours is 1 hour.
