Example: current monitoring on the N
If the current on the N is higher than 100 A for 60 seconds,
then Digital output 1 should be active for at least 2 minutes.
The following programming must be undertaken:
1. Comparator group 1
Select Comparator group 1 for threshold value monitoring.
The comparator group only has an effect on Digital output 1.
Since only one threshold value is being monitored, select
Comparator A and program it as follows:
The address of the measured value of Comparator A to be
monitored:
Addr. 110 = 866 (address of the current on the N)
The measured values for Comparators B and C are 0.
Addr. 116 = 0 (the comparator is inactive)
Addr. 122 = 0 (the comparator is inactive)
The threshold value to be observed.
Addr. 108 = 100 (100 A)
Digital output 1 should remain active for a min. switch-on
time of 2 minutes if the threshold value is exceeded.
Addr. 111 = 120 seconds
The exceedance should be present at least for the lead time
of 60 seconds.
Addr. 112 = 60 seconds
The operator for the comparison between measured value
and threshold value.
Addr. 113 = 0 (meaning >=)
2. Selection of source
Select Comparator group 1 as the source.
Addr. 200 = 0 (Comparator group 1)
3. Inverter
The result from Comparator group 1 can also be inverted
here. However, we will not do so here.
Addr. 201 = 0 (not inverted)
4. Combine the comparators
Comparators B and C were not set and equal zero.
Using the OR operator on Comparators A, B and C, the result
of Comparator A is output as the comparator result.
Addr. 107 = 0 (combine with the OR operator)
Result
If the current on the N is higher than 100 A for over 60 seconds,
then Digital output 1 is active for at least 2 minutes.
Digital output 1 becomes active. A current can flow.
