Operation and Programming

Jumpers JP1 and JP4 must be removed in order to activate this function.
The line protection function allows the branch line to be automatically isolated in case of short circuit. If this occurs, LED DL1
lights up to signal the fault (Fig. A). To reinstate the line, after eliminating the problem it is necessary to move jumper JP2 to
position B until the LED (Fig. B) goes off, then move the jumper to position A (Fig. C).
