Threshold I3
Description
By setting the threshold dip-switches to the Off position, the protection is disabled.
It defines the current value that activates the protection when exceeded (with
reference to the curve, it is the part parallel to the y-axis).
IMPORTANT: The I3 threshold set must be higher than the I2
threshold. An incorrect configuration returns an alarm signal.
