When mains are healthy, then both the D.G. Sets remain in the standby mode. When mains fail, Line Voltage Monitor (L.V.M.) senses it. Starting pulses are given to the Master D.G. Set. (Master D.G.Set is automatically selected by program.) • After satisfactory starting of the D.G.Set 1, voltage is sensed by Generator Voltage Monitor (G.V.M.). If voltage is healthy, then closing signal is given to D.G.1 breaker and it is closed. Giving corresponding pulses from the Synchronizing Panel can then automatically start load.
