Commissioning Manual
Values of the logical signals for LOVPTUV are available on the local HMI under
Main menu/Tests/Function status/Voltage/LOVPTUV(27,U<)/1:LOVPTUV.
The Signal Monitoring in PCM600 shows the same signals that are available on the
local HMI.

Measuring the operate limit of set values

1. Check that the input logical signals BLOCK, CBOPEN and BLKU are logical
zero.
2. Supply a three-phase rated voltage in all three phases and note on the local
HMI that the TRIP logical signal is equal to the logical 0.
3. Switch off the voltage in all three phases.
After set tTrip time a TRIP signal appears on the corresponding binary output
or on the local HMI.
Note that TRIP at this time is a pulse signal, duration should
be according to set tPulse.
4. Inject the measured voltages to their rated values for at least set tRestore time.
5. Activate the CBOPEN binary input.
6. Simultaneously disconnect all the three-phase voltages from the IED.
No TRIP signal should appear.
7. Inject the measured voltages to their rated values for at least set tRestore time.
8. Activate the BLKU binary input.
9. Simultaneously disconnect all the three-phase voltages from the tRestore.
No TRIP signal should appear.
10. Reset the BLKU binary input.
11. Inject the measured voltages to their rated values for at least set tRestore time.
12. Activate the BLOCK binary input.
13. Simultaneously disconnect all the three-phase voltages from the terminal.
No TRIP signal should appear.
14. Reset the BLOCK binary input.

Completing the test

Continue to test another function or end the testing by setting the parameter
TestMode to Off under Main menu/Tests/IED test mode/1:TESTMODE. If
another function is tested, then set the parameter Blocked to No under Main menu/
Tests/Function test modes/Voltage/LOVPTUV(27,U<)/1:LOVPTUV for the
function, or for each individual function in a chain, to be tested next. Remember to
set the parameter Blocked to Yes, for each individual function that has been tested.
