Description
If this parameter is set to
Enable, the system generates
an alarm when the branch
circuit breaker is closed and
no load is connected. If this
parameter is set to Disable,
the system does not generate
the alarm under any
condition.
When Harmonic alarm
enable is set to Enable and
the mains voltage harmonic
value exceeds the alarm
threshold, the system
generates an alarm.
When Harmonic alarm
enable is set to Enable and
the mains current harmonic
value exceeds the alarm
threshold, the system
generates an alarm.
When the mains voltage is
higher than the rated voltage
multiplied by the overvoltage
threshold, the system
generates an alarm.
When the mains voltage is
lower than the rated voltage
multiplied by the
undervoltage threshold, the
system generates an alarm.
