Example: Current supervision in N
If the current in N is higher than 100A for 60
seconds, digital output 1 shall be active for at
least 2 minutes.
The following programmings must be carried
out:
1. Comparator
We select comparator group 1 for the limit, as
this is the only group to influence digital output
1. As only one limit is supervised, we select
comparator A and program as follows:
Program the address of the measured value to
be supervised of comparator A.
Addr. 015 = 278 (Current in N)
The measured values for comparator B and C
are set to 0.
Addr. 020 = 0 (comparator is inactive)
Addr. 025 = 0 ( comparator isinactive)
The limit is set to.
Addr. 013 = 100 (100A)
For the minimum time of 2 minutes, the digital
output 1 must be switched on while exceeding
the limit.
Addr. 016 = 120 seconds
For a run up time of 60 seconds, the limit must
be exceeded.
Addr. 064 = 60 seconds
The
Operator
for comparison between meas-
ured value and limit.
Addr. 017 = 0 (corresponds to >=)
2. Inputs and outputs
Terminal 12 gets the function
Digital output 1
.
Addr. 002 = 1 (Digital output)

Result
If the current in neutral exceeds 100A for more
than 60 seconds, digital output 1 is active for at
least 2 minutes. Relay K1 attracts.
If memory profile 4 is selected for storage in
data memory (Option), the results of the com-
parators will be stored with date and time under
address 500.
