for analog output 1 at mounting location “D” (Port D1):
Address
5021 20 mA (D1) =
value in % to be indicated at 20 mA
Address
5026 MIN VALUE (D1)
the minimum value permitted
for analog output 2 at mounting location “D” (Port D2):
Address
5031 20 mA (D2) =
value in % to be indicated at 20 mA
Address
5036 MIN VALUE (D2)
the minimum value permitted
The maximum value is 22.0 mA. If it is exceeded (value outside of the maximum per-
missible range), then a value of 22.5 mA is output.
Example:
The phase current I
L2
is output as analog output 1 at mounting location “B”. The oper-
ational 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.

Fault Location 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):

5001 20 mA (B1) =
value in % to be indicated at 20 mA
or
Address
5003
or
5004 20 mA (B1) =
value in kilometres or miles that is
to be indicated at 20 mA.
For analog output 2 at mounting location “B” (Port B2):
Address
5011 20 mA (B2) =
value in % to be indicated at 20 mA
or
Address
5013
or
5014 20 mA (B2) =
value in kilometres or miles that
is required to be indicated at 20 mA.

Address
5021 20 mA (D1) =
value in % to be indicated at 20 mA
or
Address
5023
or
5024 20 mA (D1) =
value in kilometres or miles that
is required to be indicated at 20 mA.
For analog output 2 at mounting location “D” (Port D2):
Address
5031 20 mA (D2) =
the value in % that is required to be indicated at
20 mA
or
Address
5033
or
5034 20 mA (D2) =
value in kilometres or miles
to be indicated at 20 mA.

5017 NEG VALUE (B2)
,
5027 NEG VAL-
UE (D1)
or
5037 NEG VALUE (D2)

,
5018 OVERFLOW (B2)
,
5028 OVERFLOW (D1)
or
5038 OVERFLOW (D2)
the value of the numerical overflow (fault outside the maximum permissible range) is
set.
