Voltage harmonic alarm threshold (%)
When harmonic alarming is enabled and the main route voltage harmonic value exceeds
the alarm threshold specified by this parameter, the system generates an alarm. The value
range is 0.0%–30.0%, and the default value is 30.0%.
Current harmonic alarm threshold (%)
When harmonic alarming is enabled and the main route current harmonic value exceeds
the alarm threshold specified by this parameter, the system generates an alarm. The value
range is 0.0%–30.0%, and the default value is 30.0%.
System overvoltage threshold (%)
When the main route voltage is higher than the rated voltage multiplied by the value of
this parameter, the system generates an alarm. The value range is 105.0%–125.0%, and
the default value is 120.0%.
System undervoltage threshold (%)
When the main route voltage is lower than the rated voltage multiplied by the value of
this parameter, the system generates an alarm. The value range is 75.0%–95.0%, and the
default value is 85.0%.
Overload threshold (%)
Branch and main route current overload alarm threshold. When the branch current is
lower than the rated branch current multiplied by the value of Br. cur. shock protect (%)
and higher than the rated branch current multiplied by the value of Overload threshold
(%), the system generates a branch overload alarm. When the main route current is
higher than the rated main route current multiplied by the value of Overload threshold
(%), the system generates a main route overload alarm. The value range is
100.0%–120.0%, and the default value is 100.0%.
Overcurrent threshold (%)
Branch and main route overcurrent threshold. When the main route or branch current is
higher than the rated main route or branch current multiplied by the value of
Overcurrent threshold (%) and lower than the value of rated current multiplied by the
value of Overload threshold (%), the system generates an alarm. The value range is
80.0%–100.0%, and the default value is 80.0%.
Undercurrent threshold (%)
Branch and main route undercurrent threshold. When the main route or branch current is
higher than the rated main route or branch current multiplied by the value of
Undercurrent threshold (%) and lower than the value of rated current multiplied by the
value of Overcurrent threshold (%), the system generates an alarm. The value range is
30.0%–80.0%, and the default value is 60.0%.
Three-phase load imbalance
Main route current three-phase load imbalance alarm threshold. The value range is
0.0%–50.0%, and the default value is 15.0%. When the value obtained after the
difference between the maximum and minimum main route three-phase currents is
divided by the minimum current is higher than the value of Three-phase load
imbalance, the system generates an alarm.
LN1 power voltage lower limit (%)
ATS LN1 voltage lower limit. The value range is 5%–30%, and the default value is 20%.
When the input voltage is lower than the rated voltage x (1 - LN1 power voltage lower
limit (%)), LN1 will disable output.
LN1 power voltage upper limit (%)
