Description
No/Light load
0: Not
active
1:
Active
1
0: Not
active
The signal is active, when the function detects a current below the "No load
current" limit. This signal presents a situation where there is a very light load,
or only one or no side of the transformer is energized.
HV side inrush
detected
0: Not
active
1:
Active
1
0: Not
active
The signal is active, when the detected current rises above the "High
overcurrent" limit in the HV side.
LV side inrush
detected
0: Not
active
1:
Active
1
0: Not
active
The signal is active, when the detected current rises above the "High
overcurrent" limit in the LV side.
Load normal
0: Not
active
1:
Active
1
0: Not
active
The signal is active when the measured current is below the "Nominal
current" but above the "No load current" limit.
Overloading
0: Not
active
1:
Active
1
0: Not
active
The signal is active, when the measured current is between the "Nominal
current" and the "High overcurrent" limits.
Heavy overloading
(HVY overloading)
0: Not
active
1:
Active
1
0: Not
active
The signal is active, when the measured current is above the "High
overcurrent" limit.
