Overload signal (OL)
The overload signal (OL) is output when the current value set with
PNU C041 is exceeded.
X To configure digital output 11 or 12 or signalling relay K1 as OL,
define the current under PNU C041 at which, when exceeded,
the OL signal is activated.
X Then configure one of the outputs 11 or 12 as OL by entering
the value 03 under PNU C021 or C022, or under PNU C026 for
signalling relay K1.
