4.2.3 WIC1-2
For the relay version WIC1-2 the adjustment of protective functions can be done via DIP switches; there are 4 DIP
switches for binary coded setting of one protective parameter.
Because there are only 16 steps available for setting the individual protective parameters, scaling is coarser than
this is the case with parameter setting via software.
For the relay version WIC1-2 setting of parameters via interface is not possible any more, but it is possible to read-
out the stored fault values as well as the setting values of the WIC1.
The interface for this version can be found at the left of the relay and additionally above the DIP switch block.
