DATAKOM DKG-309 Automatic Mains Failure Unit

The DKG-309 is a comprehensive AMF unit for a single genset
standby or dual genset mutual standby operations.
In AUTOMATIC position, DKG-309 monitors mains phase
voltages and controls the automatic starting, stopping and load
transfer of the generating set in case of a mains failure and
once the generator is running, it monitors internal protections
and external fault inputs. If a fault condition occurs, the unit
shuts down the engine automatically and indicates the failure
source with the corresponding red led lamp and text.
The operation of the unit is controlled with front panel
pushbuttons. The LOAD TEST, TEST, AUTO and OFF
pushbuttons select the operating mode. Other buttons select
the display parameter scroll, alarm mute and lamp test
functions.
The DKG-309 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 the program lock
input. All programs may be modified via front panel pushbuttons,
and do not require an external unit.
The fault conditions are considered in 3 categories as
Warnings, Loaddumps and Shutdown Alarms. Measured
values have separate programmable limits for warning and
shutdown conditions. The unit is able to initiate modem calls
and sending SMS messages in fault conditions.
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 genset parameters at the time
that the fault has occurred.
The service request indicator lamp turns on at the expiration of
either engine hours or time limits.
It is possible to monitor and control the operation of the system
locally or remotely with the WINDOWS based RAINBOW
program.
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 is designed for front panel mounting. Connections are
made with 2 part plug and socket connectors.
The unit offers triple language support. Default languages are
English-Turkish and Chinese.
