Manual econ sens+ Version 1.40

Frequency drift

The supply frequency is checked. Sudden frequency changes of more than 1Hz of the

nominal supply voltage are detected.

A waveform is stored for this event. Default Value 100%

Vector jump

The 3 supply phases are checked. Jumps of the voltage angle of more than 30° are detected.

A waveform is stored for this event. Default Value 30%

Neutral overvoltage

The neutral voltage is checked. A voltage above 10% of the nominal supply voltage is

detected. Default Value 10%

Power on/off

The last power on and off times are logged.

Harmonic current

The 3 supply phases are checked. Total harmonic distortions of a current above 2% are

detected. A waveform is is stored for this event. Default Value 100%

Time change

Changes to the internal clock time are logged.
