Verifying that backup signal is released when STALARM is reset

1. Set
2. Set
3. Use default value for
4. Use default value for time delay backup trip
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
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
(3.750 s).

8. Apply START signal, and after 0.200 s apply the current above the set
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).
