1.1 General information

1.1.1 Application

The Generator Protection Unit, Ŷƥ՟3ռ is a compact microprocessor-based protection unit containing all necessary functions for protection of a synchronous/asynchronous generator. It contains all necessary galvanically separated 3-phase measuring circuits. The Ŷƥ՟3 is intended for land- and marine-based applications. It is well-suited for PLC-controlled systems, and the interfacing can be done via digital and analogue I/Os or via serial communication.

Display unit

The display unit is separate and can be installed directly on the main unit or in the front of the switchboard door (3 m display cable included). Up to two additional displays can be installed within 200 m.

The display unit shows all measured and calculated values as well as alarms and data from the event log.

Self-test

The Ŷƥ՟3 automatically carries out a cyclical self-test at start-up. If any errors are found, they will be displayed in clear text in the display and indicated with a relay output (status output).

This configuration tool is part of the PC utility software which is free of charge. With this tool, it is possible to customise the application to your needs. It is possible to dedicate specific functions or logical conditions to different inputs and outputs.

Setup

Setup is easily done via a menu structure in the display (password-protected) or via the USB PC connection and the Multiline 2 Windows ® -based PC utility software. The PC utility software can be downloaded free of charge from www.deif.com/ Documentation & Software. The utility software offers additional features such as monitoring of all relevant information during commissioning, saving and downloading of settings and downloading of software updates.

Synchronisation

As an option, the Ŷƥ՟3 can perform synchronisation of the generator. After closing of the breaker the regulation is switched OFF, and the Ŷƥ՟3 will carry out all necessary protective functions.

Engine control and protection

With the engine control and protection option added, the Ŷƥ՟3 will control the start and stop sequences of the engine and furthermore it can be used as engine protection unit providing full backup of engine shutdown channels in case the main processor fails. The option includes an engine interface I/O card with separate power supply and processor. The card is equipped with the following I/Os:

Options

In order to perfectly match the product solution to specific applications, the functionality of the Ŷƥ՟3 can be equipped with a number of available options. The options selected by the customer will be integrated in the standard Ŷƥ՟3ռ hereby securing the same user interface unaffected by whether the application needs a highly complex or a more basic genset controller.

Refer to the paragraph "Available options" for the options available

Approvals

The Ŷƥ՟3 is marine-approved by all major classification societies and is UL/cUL Listed.
