Verifying that backup signal is released when STALARM is reset
1.
Set StartMode = FollowStart.
2.
Set FunctionMode = Current.
3.
Use default value for tStartTimeout = 1.0 s.
4.
Use default value for time delay backup trip t2 = 0.150 s.
5.
Leave the inputs for CB close inactivated. These signals should not influence.
6.
Apply START signal at t=0s, and after 1.5 s apply the current above the set IPPU value.
7.
Check that STALARM signal is set after 1.0s and backup trip is blocked.
8.
Reset START signal after 3.5s, ensure that STALARM reset immediately.
9.
Set START after 3.6s, ensure that backup trip is set after t2 backup trip delay has expired (3.750 s).
11.4.9.13
Test of FollowStart&Mode behaviour
1.
Set StartMode = FollowStart&Mode.
2.
Set FunctionMode = Current.
3.
Set RetripMode = UseFunctionMode.
4.
Use default value for tStartTimeout = 1.0 s.
5.
Use default value for time delay backup trip t2 = 0.150 s.
6.
Use default value for time delay re-trip t1 = 0.000 s.
7.
Leave the inputs for CB close inactivated. These signals should not influence.
8.
Apply START signal, and after 0.200 s apply the current above the set IPPU value.
9.
Check that STALARM does not come and that re-trip TRRET is instantly set at 0.200s while the
backup trip TRBU set only when t2 expires at 0.200 + 0.150s.
11.4.9.14
Test of FollowStart behaviour
1.
Set StartMode = FollowStart.
2.
Set FunctionMode = Current.
3.
Set RetripMode = UseFunctionMode.
4.
Use default value for tStartTimeout = 1.0 s.
5.
Use for example the default value for time delay backup trip t2 = 0.150 s.
6.
Use for example the default value for time delay retrip t1 = 0.000 s.
7.
Leave the inputs for CB close inactivated. These signals should not influence.
8.
Apply START signal, and after 0.200 s apply the current above the set IPPU value.
9.
Check that STALARM does not come and that both re-trip TRRET and backup trip TRBU comes
instantly at 0.200 s (that is, as soon as current is given to the function).
11.4.9.15
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.
