DKG-207 AUTOMATIC NETWORK RESPONSIBILITY UNIT
The DKG-207 is a complete AMF unit for a single generator set operating in standby mode.
In the AUTOMATIC position, the DKG-207 monitors the mains phase voltages and controls the automatic start, stop and load transfer of the generator set in the event of a mains failure, and when the generator is running, it monitors the internal protections and external fault inputs.
If a fault occurs, the device automatically switches off the engine and indicates the source of the fault with the corresponding red LED lamp.
The device is controlled using the buttons on the front panel. The TEST, AUTO and OFF buttons select the operating mode. The other buttons select the functions of scrolling through the display parameters, turning off the alarm signal and checking the lamp.
The DKG-207 provides a full range of digitally adjustable timers, threshold levels, input and output configurations, and operating sequences. Unauthorized access to program parameters is prevented by the introduction of a program lock.
All programs can be changed using the buttons on the front panel and do not require an external device.
