Tests on “Normal” source voltage

A = 0 single-phase test,A = 1 three-phase test.

Voluntary transfer (e.g. for energy management)c action in the event of genset failureB = 0 circuit breaker N opens,B = 1 circuit breaker N remains closed.c maximum permissible genset startup time (T6)C = 0 T = 120 s,C = 1 T = 180 s.After this time has elapsed, the genset is consid-ered to have failed.

The address of the UA controller is setusing the two BBus dials.
