Operating the Machine 50Hz Mobile Generatorswc_tx000884gb.fm 243.6 Main Control Switch Positions/FunctionsPosition DescriptionAUTOMATIC TEST With the control switch in this position: The engine will start automatically. The microprocessor will test the function ofthe generator systems. The results of thetests are displayed on LCD screens. Scrollthrough the LCD screens by using the arrowkeys. The tests do not require the mains supply tobe disconnected from the end consumer.AUTOMATIC RUNNING With the control switch in this position: The engine will start automatically if themachine is not connected to a mains supply. The microprocessor is programmed to routepower (CR closed) from the mains supply tothe end consumer (utility) unless a problemwith the mains supply is detected. At such atime, the microprocessor starts the generatorand routes power (CG closed, CR open)from the generator to the end consumer. Atthe point where the mains supply is againstable, the microprocessor closes contactsCR and opens contacts CG. The engine willrun for approximately 1 minute to allow it tocool.LOCKED ENGINE With the control switch in this position: The engine will not start. Power to all generator systems is discon-nected. The mains supply is the sole source of powerto the end consumer if connected.
