11.5.11.2 Completing the test
SEMOD175058-66 v4
Continue to test another function or end the test by changing the TESTMODE
setting to Off. Restore connections and settings to their original values, if they were
changed for testing purposes.

11.5.12.1 Measuring the
operate and time limit of set values
SEMOD175021-7 v6
1. Check that the input logical signal BLOCK to the BRCPTOC function block
is logical zero and note on the local HMI that the output signal TRIP from the
BRCPTOC function block is equal to the logical 0.
2. Set the measured current (fault current) in one phase to about 110% of the set
operating current IP>.
Observe to not exceed the maximum permitted overloading of the current
circuits in the terminal.
3. Switch on the fault current and measure the operating time of BRCPTOC.
TRIP is controlled by Gate 13 in the configuration.
Use the TRIP signal from the configured binary output to stop the timer.
4. Compare the measured time with the set value tOper.
5. Activate the BLOCK binary input.
6. Switch on the fault current (110% of the setting) and wait longer than the set
value tOper.
No TRIP signal should appear.
7. Switch off the fault current.
8. Set the measured current (fault current) in same phase to about 90% of the set
operating current IP>. Switch off the current.
9. Switch on the fault current and wait longer than the set value tOper.
No TRIP signal should appear.
10. Switch off the fault current.
