Most standby units are automatic. They start, pickup the load, run and stop without an operator in attendance.
Standby units can not change the governor control setting automatically. The governor control must be preset for the proper operation of that unit. Whenever the set is exercised or operated manually, be sure the goveroner speed setting is correct for automatic operation. Check all switches to see they are properly set: Start Selector Switch in AUTOMATIC position and any Emergency Stop Switches in RUN position.
