Values of the logical signals for BRCPTOC (46) are available on the local HMI underMain menu/Tests/Function status/Current/BRCPTOC(46,lub)/BRCPTOC:X. TheSignal Monitoring in PCM600 shows the same signals that are available on the local HMI.6.3.13.1 Measuring the operate and time limit of set values1. Check that the input logical signal BLOCK to the BRCPTOC (46) function block islogical zero and note on the local HMI that the output signal TRIP from theBRCPTOC (46) function block is equal to the logical 0.2. Set the measured current (fault current) in one phase to about 110% of the setoperating current IP>.Observe to not exceed the maximum permitted overloading of the current circuits inthe terminal.3. Switch on the fault current and measure the operating time of BRCPTOC (46).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 valuetOper.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 setoperating 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.6.3.13.2 Completing the testContinue to test another function or end the testing by setting the parameter TestMode toDisabled under Main menu/Tests/IED test mode/TESTMODE:1. If another function istested, then set the parameter Blocked to No under Main menu/Tests/Function testmodes/Current/BRCPTOC(46,lub)/BRCPTOC:X for the function, or for eachindividual function in a chain, to be tested next. Remember to set the parameter Blocked toYes, for each individual function that has been tested.6.3.14 Directional underpower protection GUPPDUP (37)Prepare the IED for verification of settings as outlined in 5.1 "Preparing the IED to verifysettings".1MRK 505 293-UUS A Section 6Testing functionality71Commissioning manual
