I
I protection protects against instantaneous short circuit.
When the activation threshold is exceeded, the protection trips within a fixed non-adjustable time.
Parameters
The user can set the intervention threshold.
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 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.
