Source-changeover systems with automatic controllersCompact NS100 to 1600 87Masterpact NW 90
Note:Diagram shown with circuits de-energised, circuit breakersopen and relays in normal position.
Electrical interlocking by the IVE unitRecommended electrical control system
(1) : the “normal” and “replacement” source transfer orders must be interlocked electrically(2) : operating diagram: the SDE “fault-trip” signals are transmitted to the IVE unit. The SDEauxiliary contacts are mounted in the circuit breakers.

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.
