DESCRIPTION

The DKG-307 is a comprehensive AMF unit for a single generating set operating in standby mode.

In AUTOMATIC position, DKG-307 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.

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-307 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 2 categories as Warnings 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.

It is possible to monitor the operation of the system locally or remotely with the WINDOWS based PC utility program.

The unit is designed for front panel mounting. It is fitted into the cut-out with the steel spring removed. Connections are made with 2 part plug and socket connectors.

EVENT LOGGING

The DKG-307 records last 12 events with date and time stamp. Recorded events are alarms, warnings & generator on-load/off-load information. Event records are only displayed on the PC screen.

WEEKLY OPERATION SCHEDULE

In AUTO mode only, the unit offers the capability of defining a weekly operation schedule. Programmable parameters allow the genset to operate automatically only in defined time limits of each weekday. The internal battery backed-up real time clock allows precise switching times.

DIGITAL INPUTS

  • alarm type: shutdown / load_dump / warning / no alarm;
  • alarm polling: on engine running / always / on mains OK;
  • latching / non-latching operation;
  • contact type: NO / NC;
  • switching: BAT+ / BAT-

ANALOG INPUTS

Engine analog inputs are provided for coolant temperature and oil pressure. The analog inputs connect to resistive sender units to provide precise and adjustable protection. The inputs have programmable sensor characteristics so that they are suitable for any type and any brand of sensors.

RELAY OUTPUTS

The unit provides 6 relay outputs and 2 of them have programmable functions, selectable from a list. In addition to genset control signals any specific alarm information may be output as a relay contact. Using two Relay Expansion Modules, the number of relays may be increased up to 22, 16 of them being volt-free contacts.

STATISTICS

Following incremental counters provide statistics about past performance of the generating set:
  • Engine Hours Run;
  • Engine Hours to Service;
  • Time to Service;
  • Number of Engine Cranks;
  • Number of Genset Runs;
  • Number of Genset on load.

TELEMETRY AND REMOTE PROGRAMMING

The DKG-307 module provides the user with large telemetry facilities via its standard RS-232 serial port. The unit can be either connected to a PC or a modem for remote communication. The PC software offers local, Local Area Network (LAN), internet and modem operation capabilities. Note that the modem mode is also compatible with LAN and internet modes, so that the modem data may be served by PC for reuse in the LAN or internet.
The PC program is used for below purposes:
  • parameter upload/download;
  • remote monitoring;
  • diagnostics and analysis.

The PC software detects automatically new versions over the internet. A menu system will guide the user if he desires to download the new version.
