4.14.2 General Events Recording Function
Switch off event
When there is switch off event, the meter will add 1 total count of switch off times. Total
switch off times and time of last 10 switch off event will be recorded.
Switch on event
When there is switch on event, the meter will add 1 total count of switch on times. Total
switch on times and time of last 10 switches on events will be recorded.
Time synchronization event
When the meter time is synchronized, the meter will add 1 to total count of time
synchronization times. Total time synchronization times and time of last 10 time
synchronization events will be recorded.
Power purchase event
The meter can record total 60 valid power purchased Token, purchase energy quantity.
Power off event
When the meter is powered off, it will add 1 to total count of power off times. Total power
off times and time of last 10 powers off events will be recorded.
Phase off event
In case the meter detects some phase, voltage failure requirement is met and that
situation continues for certain time, it will be determined as the occurrence of phase off
event. The meter will add 1 to the No. of phase off times. Besides, the meter will display
the failure phase, if phase A, it will display L1; if phase B, display L2, while phase C,
display L3. Total phase off times and last 10 phases off time can be recorded. In
addition, phase A, B and C can independently record phase off event.
Reverse overload event
When the power of meter one phase is reversed and overloaded for certain seconds, the
meter will add 1 to total count of reverse overload times. The meter can record starting
time and ending time of the latest 10 overload events.
Over voltage event
When meter one phase voltage is over the set value and this state keeps for more than
certain seconds, the meter will add 1 to total count of over voltage times. The starting
time and ending time of the latest 10 over voltage events will be recorded. Besides,
phase A, B, and C can independently record overvoltage event.
Under voltage event
When meter one phase voltage is lower than the set value and this state keeps for more
than certain seconds, the meter will add 1 to total count of under voltage times. The starting
time and ending time of the latest 10 under voltage events will be recorded. Besides, phase
A, B, and C can independently record under voltage event.
