DATAKOM DKG-171 Generator/Mains Automatic transfer switch control panel (ATS)

* All prices are retail and VAT exclusive

The DATAKOM DKG-171 is a low cost, microprocessor controlled unit designed to monitor the 3-phase mains voltage, send remote start command to the generating set and make changeover of both generator and mains contactors.

The front panel mimic diagram provides information about mains and generator power availability as well as contactor positions.

The low limit of the mains and genset voltages may be manually adjusted via the potentiometer. The upper voltage limit is factory set. The unit uses high current two part connectors for easy replacement.

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.

The DKG-171 provides a TEST mode pushbutton allowing the genset to be tested without a mains failure. The Test mode is also called Emergency Backup mode which keeps the genset running and makes a quick transfer in the event of a mains failure.

In the 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 cancelled
