General Information Introduction This manual describes the Woodward Peak200 digital control for single valve steam turbines used for pump and mechanical drive applications. The scope of this manual is to provide information on programming, operation and troubleshooting of the Peak200 control.
This control’s intended use is on mechanical drive or pump control applications (generator drive units should use the Woodward 505 product). The Peak200 can be configured to operate as a stand-alone turbine control unit or can be interfaced via hardwire signals and/or a Modbus communication link to be operated from a plant’s Distributed Control System.
Four LEDs located on the left side – a Summary Trip, Summary Alarm, IO Lock, and CPU Health. The GAP program controls the two Summary LEDs and relate to the status of the control. The IOLOCK and CPU LED’s relate to the H/W status. Woodward...
MPU keeps the turbine operating. The Peak200 determines which MPU is outputting the highest frequency and uses that frequency as the speed feedback to control the turbine. When only one MPU is used, the user can disable the second MPU input. Woodward...

Peak200 Description and Features The Peak200 controller is a significant upgrade to the existing Peak150 product line with enhanced CPU, Graphical display, communications, and I/O functions. Note: This controller supports expanded I/O options when using Woodward CAN distributed LinkNet I/O nodes. Features ...

To use this controller an analog input channel must be configured for use as the Process/Cascade input. The Peak 200 will use this input as the Process Variable (PV) for this controller. If at any time while in Cascade control this PV faults, the Cascade controller will be disabled and the speed setpoint will remain at its current setpoint (bumpless).

This menu is used to configure an optional process control loop. The output of this PID control will determine the setpoint for the speed control.

If the accumulated mechanical gain (actuators, valves, valve linkage, etc.) is very high, the Peak 200’s gain must be very low to be added to the system gain required for system stability. In cases where a small change in the Peak 200's output results in a large speed or load change (high mechanical gain), it may not be possible to take the Peak 200's gains low enough to reach stable operation.

The CPU LED should always be on and GREEN. If it is not, see the "CPU Flash codes in the diagnostic section": Typically if it is solid RED or giving a flash code, it will require a power cycle to possibly clear the issue. Woodward...
If actual speed is less than the speed called for by the speed reference, check for speed droop. Droop causes the actual speed to be less than the speed reference. If the Remote Speed input values are reading incorrectly, ensure the input wire shielding is properly grounded at the Peak200 control end only. Woodward...

The Woodward SOS Servlink OPC server ("SOS") provides an OPC interface for Woodward controls. It runs on a Windows PC that accesses data on controls using the Woodward proprietary Servlink protocol through an Ethernet connection. Woodward OPC client applications, such as Monitor GAP and Control Assistant connect to SOS by selecting a 'Servlink OPC server' connection.
Servlink-to-OPC Server (SOS) The Woodward SOS tool is a sub-component of Control Assistant that handles all of the communications between one or many Peak200’s on a network and the PC. It can be run independently, which is a useful way to clearly establish a connection prior to using the Control Assistant or other programs.
Figure D-5. SOS - Enter Peak200 TCP/IP address The SOS program will locate the control and establish a Woodward Servlink connection between the control and your PC. This will take a few seconds to establish; the dialog box should now look like this (with the IP address being equal to what you typed in above).
Viewing Datalog files Prior to installing Control Assistant, you must install the Microsoft .net framework program which is available on the Woodward website (www.woodward.com). This will install some operating system library files that are used by Control Assistant. Installing Control Assistant License Agreement &...
Define the desired directory to save Control Assistant and press ‘Next’. It is preferable to use the default, as it will keep all Woodward Software in a common folder. If the program folder field is blank, type in “Woodward” and the install will create a program folder named Woodward.

Use File/Open to open a previously saved trend script file (if you have one). To create new trends, the user will need some understanding of how Woodward’s GAP software is constructed as well as some specific knowledge of the Peak200 application software. If the user is not familiar with GAP, recommend limiting use to existing trend script files.

AppManager Service Tool File Management with App. Manager AppManager is a Windows based remote access tool for Woodward controls. The Peak200 is loaded with a service that allows it to interface with AppManager. AppManager is used to manage the applications on the Peak200 and provide access to operating system information.

If this occurs the user must first delete the file on the control before the new one can be transferred. Woodward typically adds a revision or a build number to the end of the file name so that any updates can be added to the control and the previous revisions will still be available.

Use the AppManager tool to install a service pack to update the OS or the real-time process that executes the GUI application. Woodward representatives or a service bulletin directing the user through the process typically does this. Nominally, these are the steps: 1.
