- 4. 4 Current to Pressure Converter - II Description: The CPC is an electrohydraulic pressure-regulating valve that utilizes a very accurate internal pressure sensor and PID controller to precisely control steam turbine valves. The CPC consists of a valve-actuator assembly, pressure sensor, and electronic driver module. The unit’s driver module accepts one (or two) 4-20mA-pressure setpoints and compares these setpoints to the sensed oil pressure, to accurately control turbine valve oil pressure.

Editor's Notes
- This introduction slide is a great talk tool. Key points to talk to are: GAP - Graphical Application Programmer. The Atlas control executes the GAP code as our existing MicroNet control. GAP has several benefits that make it an excellent tool for turbine applications. This is discussed in more detail later. Pre-defined and fully tested function block library Deterministic Rate group execution Multiple File execution for separation of Core Engine control and Sequencing Self Documentation and revision control Suite of service tools and simulation tools The Atlas platform uses a PC104 bus and hardware modules that allow it to be built up to meet the applications functional needs. This allows one platform to meet a huge variety of applications and benefits our customers by leveraging a higher market volume to minimize cost. The Atlas Core Fuel control is designed as a flexible/modular control platform. The target application is on-skid core fuel control. Package sequencing and can be accomplished directly out of the Atlas control using on board and distributed I/O or by interfacing with a PLC, or PC. The control uses a Pentium CPU and a real time extension to the NT operating system. This allows us to take advantage of the PC economics driving the hardware and software tools. The result is a cost effective platform with a very open interface. Woodward has been running field applications with the Pentium and NT operating system in our MicroNet control since November 98.
