Test Trip

The REB500 system provides a test facility to activate and deactivate a test trip per bay. For
this purpose the signal 21120_EXT_TEST_TRIPcan be set and reset via bay. For this purpose
the signal 21120_EXT_TEST_TRIP can be set and reset via the LHMI Test Trip menu.
The LHMI Test Trip can be combined with a current criteria, so that the test trip is only issued
if the current of one phase does not exceed a certain factor of the rated current.
