DATAKOM DKG-173 230/400V Generator / Mains Automatic Transfer Switch Panel (ATS)

The DATAKOM model DKG-173 is a DIN Rail mounted ATS controller not requiring DC supply. The unit monitors 3-phase mains voltages, sends remote start command to the generating set and performs changeover of both generator and mains contactors. The front panel leds provide information about mains and generator power availability as well as contactor positions.

Mains return delay and genset contactor delays are adjustable between 1 and 40 seconds through front panel knobs.

Description

OPERATION

When both mains voltages are over the limit:

  • RMCRST leds are on.
  • The MCB terminal is supplied with voltage R.
  • The REMOTE START relay contact is open.

If any AC phase voltage goes below limit:

  • RMCRST leds turn off.
  • The MCB terminal is open.
  • The REMOTE START relay contact closes.

The REMOTE START output is expected to provide a genset running condition.

When the genset voltage G is over the limit:

  • The G led turns on.
  • At the expiration of the genset contactor delay the GC  led  turns  on  and  the GCB terminal is supplied with voltage G.

When both mains voltages are over the limit:

  • R and RST leds turn on.
  • At the expiration of the mains return delay the MC led turns on and the MCB terminal is supplied with voltage R.
  • The REMOTE START relay contact opens.

The  contactor delays for the genset and are manually adjusted via potentiometers situated on the front panel of the unit.
