11. Reset the ENABLE binary input.
12. Switch the fault current on.
No TRIP signal should appear.
13. Disable the fault current.
11.5.9.3 Completing the test
Continue to test another function or end the test by changing the TESTMODE setting to Disabled.
Restore connections and settings to the original values, if changed for testing purposes.
11.5.10 Overcurrent protection with binary release BRPTOC
Prepare the IED for verification of settings outlined in Section
Logical signals for BRPTOC protection are available on the local HMI under Main menu /Settings /IED
Settings /Current protection /OvercurrBinRel (50, 2I>) /BRPTOC (50, 2I>):x .
Logical signals for BRPTOC protection are available on the local HMI under Main menu /Settings /IED
Settings /Current protection /OvercurrBinRel (50, 3I>) /BRPTOC (50, 3I>):x .
The Signal Monitoring in PCM600 shows the same signals that are available on the local HMI.

11.5.10.2 Measuring the operate limit of set values
1. Check that the input logical signals BLOCK and BLKTR and the output logical signal TRIP are all
logical zero.
2. If required, activate the input ENABLE on the BRPTOC function block.
3. Set MeasType to DFT for overcurrent operation.
4. For a short while inject a current (fault current) in phase A to about 110% of the set operating
current I>, and switch the current off.
Observe to not exceed the maximum permitted overloading of the current circuits in the IED.
