The DKG-707 is a comprehensive Manual and Remote Start unit for multiple generating sets operating in parallel with load sharing.
The unit supports both diesel and gas gensets based on electronic and non-electronic engines.
Up to 8 gensets may be combined together using DKG-707 units without the need for extra modules. The communication between modules is made with the Datalink connection.
In AUTOMATIC position, DKG-707 monitors the Remote Start input and controls the automatic starting, stopping, synchronizing and load sharing of the generating set.
When the genset is running, it monitors internal protections and external fault inputs. If a fault condition occurs, the unit shuts down the engine automatically, indicates the failure source on the LCD display and turns on the red ALARM led.
On a Remote Start request, the sufficient number of gensets to supply the programmed prime power are started, synchronized and closed to the busbar. They will share the load in equal percentage of the rated genset power. The master unit will monitor continuously the power delivered to the load and starts/stops slave gensets automatically.
The genset which is to run first is automatically elected as master. If the master genset fails or the running priority changed, a new master will be elected automatically.
The unit provides user configurable speed governor and AVR outputs allowing direct connection to various engines and alternators. The AVR output is fully isolated for a more flexible usage.
The operation of the unit is controlled with front panel pushbuttons. The TEST, AUTO, MANUAL and OFF pushbuttons select the operating mode. Other buttons run and stop the genset, control synchronizing and load sharing, select the program mode entry/exit, scroll display parameters, provide alarm mute and lamp test functions.
The DKG-707 provides a comprehensive set of digitally adjustable timers, threshold levels, input and output configurations and operating sequences. The unauthorized access to program parameters is prevented by a 3 level password system. All programs may be modified via front panel pushbuttons, and do not require an external unit.
The modification of programs may be disabled also by the hard wired PROGRAM LOCK input.
The fault conditions are considered in 3 categories as Warnings, Load-dumps and Alarms. Measured values have separate programmable limits for warning and alarm conditions.
The service request indicator lamp turns on at the expiration of either engine hours or time limits.
