DKG-107 AUTOMATIC MAINS FAILURE UNIT The DKG-107 is a low cost microprocessor based digital unit offering all basic functions needed for the automatic control of a genset including changeover contactors. The unit fits into a standard 72x72mm panel meter opening and offers a very cost effective and space saving solution for the basic genset control. In automatic mode, the unit monitors 3 phases of the mains and controls the automatic starting, stopping and load transfer of the generator. When the engine is running, the unit monitors fault conditions and shuts-down the engine automatically in the occurrence of an alarm. The alarms are identified by a group of LEDs displaying only the first occurring one. DKG-107 provides factory adjusted timers. However it has Oil Level Switch and 60Hz options selected by jumper switches and a potentiometer adjusted low voltage limit situated at the bottom of the unit.
