The 2301E has four modes of operation:

Speed Control

Provides a wide range of dynamic flexibility. Can be used for pumps or compressors.

Remote 4-20 mA speed reference via configurable analogue input.

Asynchronous Load Sharing

Compatible with most existing analogue load sharing speed control systems.

Now with soft loading and unloading capabilities.

Dropped Base Load

Adjustable load control using discrete lift contacts.

Constant Speed Base Load

Provides constant load level operation against the mains bus. 

Load settings can be fixed or changed using discrete raise and lower inputs or a remote 4-20 mA input.

The Woodward 2301E provides load sharing and speed control for generators driven by diesel or gas

engines.

With the flexible configuration software in the 2301E hardware,

Application variations can now be selected using an external computer (PC).

Applications can be changed to accommodate engine speed ranges, gear tooth counts,

and forward and reverse selections with a simple software setup.

The 2301E is capable of communicating using the Modbus® * RTU protocol,

operating as a Modbus slave device via an RS-422 driver.

The 2301E includes

 1 load cell circuit

 1 actuator driver, 4-20 mA, 0-20 mA, 0-200 mA or PWM

 1 MPU speed sensor

 1 configurable analogue output

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.

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.

The QuickTrip trip block assembly is designed for use in steam, gas, and hydro

turbine shutdown systems for quick and reliable dumping of the turbine’s trip oil

header. This integrated trip block assembly is intended for use on mechanical-drive

or generator-drive steam turbines that use low pressure (5–25 bar / 73–363 psi)

hydraulic trip oil headers.

The QuickTrip’s fault tolerant design makes it ideal for critical steam turbine

applications, where turbine up-time and availability are essential. This trip block

assembly’s 2-out-of-3 voting design provides users with a very high level of system

reliability as well as compliance with industry standard API-670.

The QuickTrip is certified for use in IEC61508 based turbine safety systems, and

when paired with the Woodward ProTechTPS, can be applied into systems that

require a “Safety Integrity Level – 3” rating or below.

Manually Stroking QuickTrip (powered)

Manually Stroking Valve Procedure:

1. To manually stroke the QuickTrip valve, the actuators must be powered with 24 VDC. Make sure the

power supply is connected and operating while performing this procedure. This can be verified by

viewing the LED status through the sight window on top of the valve. One or two blue LED’s indicate

that the power supply is connected and is turned on.

2. If QuickTrip is in a run state, as indicated by a green LED as viewed through the sight glass,

QuickTrip may be manually tripped either by de-energizing the logic solver interposing relay to initiate

a trip state or by tripping the breaker to the Control In discrete input terminals on the QuickTrip

electronics module (terminals 5 and 6 of TB2).

3. If QuickTrip is in a trip state, as indicated by a red as LED viewed through the sight glass, QuickTrip

may be energized to close either by activating the logic solver interposing relay to initiate a run state

or by supplying a separate 24 VDC input to the Control In terminals on the QuickTrip electronics

module (terminals 5 and 6 of TB2).

Manually Stroking QuickTrip Using ProTechTPS (powered)

Manually stroking valve using ProTechTPS procedure:

1. If QuickTrip is in a run state, as indicated by a green LED as viewed through the sight glass,

QuickTrip may be manually tripped by de-energizing the ProTechTPS interposing relay to initiate a

trip. This may be done by using the Temporary Overspeed Setpoint Test (see ProTechTPS product

manual for more detailed instructions on this function).

2. If QuickTrip is in a trip state, as indicated by a red LED as viewed through the sight glass, QuickTrip

may be energized to close by activating the ProTechTPS interposing relay to initiate a run state. This

may be done by pressing the RESET button on the front panel of the ProTechTPS (see the

ProTechTPS product manual if module does not reset when the RESET button is pressed).
