4. Decrease the voltage slowly and note the reset value.
5. Set and apply about 20% higher voltage than the measured trip value for one phase.
6. Measure the time delay for the TRST1 signal and compare it with the set value.
7. Check the inverse time delay by injecting a voltage corresponding to 1.2 × Vpickup>.
8. Repeat the test to check the inverse time characteristic at different over-voltage levels.
9. Repeat the above described steps for Step 2 of the function.
11.5.2.2

Extended testing

1. The tests above can be repeated for 2 out of 3 and for 3 out of 3 operation mode.
11.5.2.3

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.
