main voltage output is OFF; so, threshold tests are performed
the following way:
. After pressing ON, values are adjusted first so that the relay
does not give permission;
. We make sure that the relay is not tripped looking at light
(42); then, we slowly modify the parameter until the relay
trips. It may occur that the relay does not trip, even if you
have reached the minimum value: this is because you moved
too fast. Normally you should reach the limit (VN, or 0°, or 50
Hz) in 20 s or more; so, in this instance, repeat the test more
slowly.
