The DKG-329-DUAL iis designed to control a 3-phase transfer panel featuring 1 mains and 2 gensets. It monitors 3-phase mains voltages, sends remote start commands to generating sets 1 and 2 and controls the changeover of both generator and mains contactors.
The unit provides equal aging of gensets, running the next genset at each mains failure and periodically switching gensets during mains failures.
If a fault condition occurs, the unit disables the remote starting of the corresponding genset automatically and indicates the failure with led lamp and text.
The unit provides a comprehensive set of digitally adjustable program parameters. 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 any external unit.
Last 100 faults are stored in the event log file. The event log includes not only the date-time information, but also a comprehensive list of measured parameters at the time that the fault has occurred.
The WINDOWS based RAINBOW program allows remote monitoring and control.
The unit supports MODBUS protocol enabling communication with PLCs and building management systems. The MODBUS protocol is also supported through GSM and PSTN modems.
The unit offers multiple language support.
