Woodward 505DR Dual Redundant Turbine Controller Description

Description

Like the MicroNet Plus, the 505XT system designates one controller

as the System Controller (Syscon), actively controlling the fan.

The second device is configured as a backup.

The system automatically evaluates the health of the Syscon and initiates a fast switchover in the event of a failure.

Switchover can also be initiated manually. The system closely synchronises

the Syscon's software status and memory with the backup,

ensuring that the control output remains stable and does not affect turbine operation (a true ‘bufferless’ switchover).

If the optional HMI version is selected, the display and keypad are redundant

(input from either keypad will command Syscon, and the display can be independently selected to show different screens.

For example, one screen can display speed and speed settings, and another can display a steam map.

Woodward's optional RemoteView programme allows remote monitoring from any networked PC.

The programme can be used either with the rear panel mounted version (as the main HMI)

or as an additional remote monitor to the HMI version.

The optional FTM (Field Terminal Module) allows easy multiplexing of

redundant signals and facilitates fast installation and commissioning.

Cost-effective design

The 505DR is a G-efficient redundant turbine controller.

It consists of a turbine controller, system sequencer, operator control panel and first-out indicator.

The design minimises external equipment and wiring for easy troubleshooting.

Like the 505XT, the 505DR can be fully configured in the field

(under password control by knowledgeable personnel) and minor functional

changes can be made while the turbine is running online.

Minor functional changes can be made online while the turbine is running.
