Parameter
Description
Enable
By setting the threshold dip-switches to the Off position, the protection is disabled.
Threshold I3
It defines the current value that if exceeded activates the protection (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.
