DST4602Evolution

DST4602Evolution is fully equipped with internal Load Sharing, Synchronizer and W and VAR regulation. This controller includes a CAN J1939 interface, supporting a wide range of engines (Volvo Penta, Scania, Perkins, MTU, Deutz, Cummins, John Deere, Caterpillar and others).
It can be also used with traditional engines, where measurements and control are performed by the embedded analogue interfaces.

DST4602Evolution can be used together with all Sices genset controllers (GC600, GC400). In case of multiple gensets in parallel with the mains where the reverse synchronization is required, and it can be also interfaced with the Sices mains controllers (MC200, MC400), to avoid in this way any further blackouts on the loads.

The controller’s configurable parameters make standard and customized tasks easy to manage. All the parameters can be set directly by the controller’s keyboard or, alternatively using the free software tool (BoardPRG3), available from Sices’ website. It is also available a free PLC software editor, (SicesPlcEditor) to set the PLC logics.

The enhanced and large 7” graphic colour display with TFT technology, is a user-friendly interface, conceived for a quick and easy visualization of measures and alarms coming from the genset. This controller stores events and periodical data in the internal memory, this information can be read from the front panel display.

DST4602Evolution provides several communications interfaces for local or remote control. In case of complex applications, like Oil&Gas stations, the inbuilt protections can be expanded by using the external protection relay D-PRO.

For each local DST4602Evolution it is possible to add one or more remote displays, called DST4602Remote.
This solution is usually recommended in case of remote-control room where the genset monitoring is required. It is possible to connect up to 4 remote displays to a single DST4602Evolution controller.

Connection Between DST4602Evolution and DST4602Remote

• Via RS485 Modbus RTU (max 800mt)
• Via ethernet TCP/IP (max. distance 100mt without any hub)
• If via ethernet, it is possible to connect several DST4602Remote to one local controller

Graphic display

DST4602Remote is equipped with a powerful 7’’ colour graphic display TFT - 800x480 pixel.

Key selector controls

• Command disabled: no operation is allowed
• Command enabled: all operations are allowed
• Remote reset: reset of alarms/warnings

Push buttons

• REMOTE START: starting is enabled if the operating mode of the local controller is in AUTO
• REMOTE STOP: used to remotely stop the genset. If the genset has been started by the DST4602Remote, the “REMOTE STOP” stops the genset with the cooling operations.
  If the genset has been started by the local DST4602, the “REMOTE STOP” stops the genset immediately without any cooling operations.
• GCB: for manual opening/closure of the Genset Circuit Breaker.

Security

System safety can be increased with a dedicated password, on both local and remote controller.

DST4602Evolution has a built-in innovative and automatic start sequence, that allows to achieve a fast paralleling of several gensets in a maximum time of 9 - 15 sec. (it depends on the alternators and engines features).

The advanced system so called “Fast Paralleling” or “Dead Bus Paralleling”, is an effective solution for those sensitive stations where any mains failure, even for a few seconds, could cause huge problems to people and data security, by creating damages during the production processes (banks, hospitals, data centres, etc…).

Using the Fast Paralleling feature, gensets are switched on, synchronized and ready to supply the loads in a few seconds from the mains failure signal.
