Description
The DATAKOM model DKG-107 automatic mains failure unit 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. DKG-107 provides factory adjusted timers. However it has Oil Switch Type and 60Hz options selected by jumper switches: If the jumper is placed between:
A & B : 50 Hz nominal, Oil Level switch
B & C : 50 Hz nominal, Oil Pressure Switch
C & D : 60 Hz nominal, Oil Pressure Switch
D & A : 60 Hz nominal, Oil Level Switch
The unit has also a potentiometer in order to adjust the mains and genset low voltage limit. This potentiometer is situated at the bottom of the unit. he low voltage limit is adjustable between 70 and 270V-AC. The mode selection is made via a pushbutton which toggles between OFF and AUTO modes. The unit saves the last operation mode in a non-volatile memory and resumes to this mode when powered up. In OFF mode the unit monitors 3 phases of the mains. If all mains phase voltages are above the limit set with the potentiometer, the mains contactor is energized. In AUTO mode, the unit monitors 3 phases of the mains. If at least one of the mains phase voltages is below the set limit, it starts the engine and transfers the load to the generator. When the engine is running, it 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. When all mains phase voltages are above the limit, the unit waits for the mains stabilization timer then transfers the load to the mains. If Cooldown operation mode is selected, the engine runs during the Cooldown period, otherwise it stops immediately. The occurrence of below fault conditions will cause the engine to be stopped immediately:
-Overspeed,
-Underspeed,
-Low generator voltage, (speed led flashes)
-High engine temperature,
-Low oil pressure/level.
To reset the alarms press the mode selection button. If the mode selection button is hold pressed for 2 seconds, the unit will select the lamp test mode and all LEDs will turn on.
