HARMONIC ANALYSIS
Controller has harmonic analysis function for voltage and current, which can monitor harmonic
distortion rate and 3-21 times harmonic component of voltage/current of all phases.
In main menu interface, select "4. Harmonic Analysis", and press
key to enter harmonic analysis
interface.
Enter harmonic analysis page, press
and
key to select the voltage needed to analyze;

AUTOMATIC SWITCH OPERATION
Press
key, and auto mode indicator becomes light and the controller is in the auto mode.
Under auto mode, the controller will switch automatically to ensure power supply for loading according
to S1&S2 status, switch priority and Auto Trans./Restore status. The following illustrates the control
logics by the example of "S1 Master", "S1 Mains S2 Gen".
