The signal DLECND must be connected to the input LDCND for selected mho impedance
measuring zones ZMOPDIS.
In case several loops have to be released at the same time, the value is the sum of the values
for all loops, like the value for three-phase fault is the sum of the phase-to-phase loop
values (8+16+32=56).
