The values for the negative fault location and the overflow must be set as large as pos-
sible since the linear transmission range of the fault location values ends 0.5 mA be-
low the smallest of these values.
Set in Addresses
5009 Tmax OUTPUT(B1), 5019 Tmax OUTPUT(B2), 5029 Tmax
OUTPUT(D1)
or 5039 Tmax OUTPUT(D2) for how long the valid fault location is to
be delayed. If a new fault occurs, the fault location is updated. Having set the value to
∞ the transmission of the last fault location will not be interrupted until a further one is
calculated.
Example:
The fault location must be output in kilometers at mounting location “B” via the analog
output 2. At a value of 20 mA the device must indicate 50 km. For a fault in reverse
direction a value of 19.84 mA should be indicated, in the event of overflow a value of
22.5 mA. The value must be output for a time period of 5 s provided that no fault oc-
curs in the meantime.
Settings:
Address
5013 20 mA (B2) = 50 km,
Address
5017 NEG VALUE (B2) = 19.84 mA,
Address
5018 OVERFLOW (B2) = 22.50 mA,
Address
5019 Tmax OUTPUT(B2) = 5.00 s.
Inthiscasethefaultlocationvaluescanbeoutputupto19.84mA–0.5mA=
19.34 mA. Theoretically, this corresponds to a value of 48.35 km.
Maximum Fault
Current
Set the conversion factor and the maximum output time for the maximum fault current:
For Analog output 1 at mounting location “B” (Port B1):
Address
5002 20 mA (B1) = valueinAmpstobeindicatedat20mA
Address
5009 Tmax OUTPUT(B1) = maximum output time of the value.
For Analog output 2 at mounting location “B” (Port B2):
Address
5012 20 mA (B2) = valueinAmpstobeindicatedat20mA
Address
5019 Tmax OUTPUT(B2) = maximum output time of the value;
for Analog output 1 at mounting location “D” (Port D1):
Address
5022 20 mA (D1) = valueinAmpstobeindicatedat20mA
Address
5029 Tmax OUTPUT(D1) = maximum output time of the value;
for Analog output 2 at mounting location “D” (Port D2):
Address
5032 20 mA (D2) = valueinAmpstobeindicatedat20mA
Address
5039 Tmax OUTPUT(D2) = maximum output time of the value;
If the maximum output time value is set to
∞, the transmission of the last fault current
will not be interrupted until a further one is calculated.
The maximum value is 22.0 mA. In case there is an overflow (value is outside of the
maximal permissible threshold), then 22.5 mA is output.
Example:
The fault current must be output in mounting location “D” via analog output 2. 20 mA
corresponds to a value of 20000 A. The value must be output for a time period of 5 s
provided that no fault occurs in the meantime.
