ATS Panel
Control System: SmartGen Controller and deep-sea controller integrating digital, intelligent and network techniques is used for automatic control system of diesel generator. It can carry our function including key/automatic start / stop. Ammeters, current transformer, Volt meter, Volt selector switch, hour counter, frequency meter, oil pressure gauge, water temperature gauge, battery conditioner meter, data measure and alarming. High water temperature, low oil pressure, over-speeds and overloads protection. ATS with different current, AMF control panel and circuit breaker can be selected. Adobe Systems

General Control & Synchronization Panel
Synchronizing Panel Synchronizing panel will operate on an automatic mains failure system, so that when the main supply is interrupted on one or all phases (after an adjustable delay period) the generator sets will start-up together. After an initial warm-up period (adjustable) the generators will synchronize with each other by means of motorized circuit breakers or contactors onto a common bus-bar. Next, the motorized change-over switch will be closed and the load will be connected to the main distribution box.The load share units continuously monitor the load and during low demand periods one or two generators will be shut down to save on fuel consumption. As demand rises again the second generator and third generator will be restarted, synchronized and reconnected to the load. When the AMF control unit detects that the main supply has been restored an adjustable observation period is activated before the main supply is reconnected. A cool

down period will then follow, after which the generator sets will be shut down.
