Description of DKG171
The DKG171 is a microprocessor-controlled unit designed to monitor the 3-phase mains voltages, send a remote start command to the generating set and make a changeover of both generator and mains contactors.
The front panel mimic diagram provides information about mains and generator power availability as well as contractor positions.
The low limit of the mains and Genset voltages may be manually adjusted via the potentiometer situated on the left side of the unit. The leftmost position corresponds to 70 volts, the middle position to 170 volts, and the rightmost position to 270 volts-AC.
The DKG-171 continuously monitors the AC mains phase voltages. If at least one of the phase voltages goes outside set limits, it initiates a transfer cycle like below:
-The green MAINS led turns red.
-The unit de-energizes the mains contactor output and the green LOAD MAINS led is extinguished.
-After Wait Before Remote Start Delay, the Remote Start output is energized. The generator remote start unit receives this signal and runs the engine.
-When the generator phase voltage is within set limits, the yellow GENSET led will illuminate and the unit will allow the Genset to run without load during the Engine Heating Period.
-When the Engine Heating Period is elapsed, the yellow LOAD GENSET led will start blinking and the unit will wait for the Generator Contactor Delay.
-At the end of the Generator Contactor Delay, the generator contactor output will be energized and the yellow LOAD GENSET led will illuminate steadily.
-When all mains phase voltages are within limits, the MAINS led will turn to green and the unit waits for Mains Return Delay for stabilization.
-At the end of the Mains Return Delay, the yellow LOAD GENSET led is extinguished, the generator contactor output is de-energized and the green LOAD MAINS led will start blinking. The unit will wait for Mains Contactor Delay.
-At the end of the Mains Contactor Delay, the green LOAD MAINS led will illuminate steadily, the mains contactor output is energized and the Remote Start output is de-energized. The unit will wait ready for a new mains failure sequence.
The DKG-171 provides a TEST mode pushbutton allowing the Genset to be tested without a mains failure.
In TEST mode, the Remote Start output will be energized but no load transfer will take place unless the occurrence of a mains failure. If the mains fail, the load will be transferred to the Genset. When the mains voltages are within limits the load will be transferred to the mains, but the Genset will be kept running. It will only stop if the TEST mode is canceled.
