The maximum value is 22.0 mA. If it is exceeded (value outside of the maximum
permissible range), then a value of 22.5 mA is output.
Example:
The phase current I is output as analog output 1 at mounting location "B". The
L2
operational nominal current should correspond to 10 mA output, which means that
20 mA correspond to a rate of 200 %. Values below 4 mA are not valid.
Settings:
Address   P$ %
Address  0,1 9$/8( % =  mA.
For the fault location the conversion factor, i. e. the value to be output, is also set to
20 mA. Dependening on whether the fault location should be output in per cent of the
line length or in length unit, set the following:
For analog output 1 at mounting location "B" (Port B1):
Address   P$ %
or
Address  or   P$ %
to be indicated at 20 mA.
For analog output 2 at mounting location "B" (Port B2):
Address   P$ %

For analog output 1 at mounting location "D" (Port D1):
