If the settings are changed to speed up times during the tests, they
must later be reset and verified.
2.1 Set operation = Off.
2.2 Apply a stationary current over the set value.
2.3 Apply a start pulse to BFP--STL1.
2.4 Verify that neither retrip nor back-up trip is achieved.
3.1 Set RetripType = No I>check, I> = 100% I
3.2 Apply a stationary three-phase current over the set value.
3.3 Apply a start pulse to BFP--STL1.
3.4 Verify that retrip in phase L1 is achieved.
3.5 Apply a stationary current over the set value.
3.6 Apply a start pulse to BFP--ST3PH.
3.7 Verify that all three retrips are achieved.
4.1 No retrip function
4.1.1 Set RetripType = Retrip Off and I> = 100% I
4.1.2 Apply a stationary three-phase current over the set value.
4.1.3 Apply a start pulse to BFP--STL1.
4.1.4 Verify that retrip in phase L1 is not achieved.
4.2 Retrip function with current check
4.2.1 Set RetripType = I> check, t1 = 100 ms and I> = 100% I
4.2.2 Apply a stationary three-phase current over the set value.
4.2.3 Apply a start pulse to BFP--STL1.
4.2.4 Verify that retrip is achieved.
4.3 Retrip function without current check
4.3.1 Set RetripType = No I> check, t1 = 100 ms and I> = 100% I
4.3.2 Apply a stationary three-phase current over the set value.
4.3.3 Apply a start pulse to BFP--STL1.
4.3.4 Verify that retrip is achieved.
