If load current decreases for partial or total load failure (sensitivity 20% standard adjustable via
RS485) the yellow LED becomes ON and alarm relay changes status.
If CD3000M is still in conduction with no input signal (LED green OFF) it means that there is a
short circuit on thyristors and red LED (SC) becomes ON.
The diagnostic is active only when the switching period is longer than 60ms (3 main
voltage cycles).
If the load has been changed calibration procedure must be done again.
