DKG-329 User Manual
WITH UNINTERRUPTED TRANSFER AND MULTIPLE GENSET SUPPORT
DESCRIPTION
The DKG-329 is microprocessor controlled unit
designed to monitor 3-phase mains voltages, send
remote start command to generating sets and
control the changeover of generator and mains
contactors.
The unit offers an internal synchroscope for
uninterrupted transfer in both directions. The
number of gensets to run before transfer is
selectable, allowing multiple genset support.
If a fault condition occurs, the unit disables the
remote starting automatically and indicates the
failure with the corresponding 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.
