Description
When the system frequency
is higher than the rated
frequency plus the value of
this parameter or is lower
than the rated frequency
minus the value of this
parameter, an alarm is
generated.
If this parameter is set to
Enable, an alarm is
generated when the alarm
condition is met.
If this parameter is set to
Enable, an alarm is
generated when the alarm
condition is met.
If this parameter is set to
Enable, the system generates
an alarm when the branch
circuit breaker opens. If this
parameter is set to Disable,
the system does not generate
the alarm under any
condition.
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.
