This manual describes the Woodward Peak 150 digital control for steam turbines and the hand-held programmer (9905-292) used to program it. The following topics are covered in the chapter indicated: ? Installation & Hardware (Chapter 2) ? Overview of Turbine System Operation (Chapter 3) ? Peak 150 Inputs & Outputs (Chapter 4) ? Peak 150 Control Functions (Chapter 5) ? Explanation of Operating Procedures (Chapter 6) ? Overview of Hand Held Programmer and Menus (Chapter 7) ? Set up of Configuration menus (Chapter 8) ? Set up of Service menus (Chapter 9) ? Detailed Functional Block Diagram (Chapter 10) ? Modbus Communications (Chapter 11) ? Troubleshooting (Chapter 12) ? Service Options (Chapter 13) ? Program Worksheets (Appendix) Parameter names are shown in all capital letters and match the syntax as seen on the Hand Held Programmer or the plant wiring diagram.

Packaging Figure 2-1 is an outline drawing of the Peak 150 control. All Peak 150 control components are contained in a single, NEMA 4X enclosure. The enclosure can be mounted indoors or out. Access to internal components is through a righthand-hinged door which is held closed by six captive screws. The approximate size of the enclosure is 19 x 12 x 4 inches (approximately 483 x 305 x 102 mm). The enclosure has two openings in the bottom for wiring access. One hole is approximately 25 mm (1 inch) diameter, and the other is approximately 38 mm (1.5 inch) diameter. These holes accept either English or metric standard conduit hubs.

All internal components are industrial grade. The components include the CPU (central processing unit), its memory, the switching power supply, all relays, all input/output circuitry, and all communications circuitry for the front door display, touch keypad, remote RS-232, RS-422, and RS-485 Modbus communications.

Mounting The standard Peak 150 control enclosure must be vertically mounted on a wall or 19" (483 mm) rack, allowing sufficient room for lid opening and wiring access. Two welded flanges, one on the right side and one on the left side, permit secure mounting.

Electrical Connections All electrical connections must be made through the two openings in the bottom of the enclosure to the terminal blocks inside the enclosure. Route all low-current lines through the large wiring port. Route all high-current lines through the small wiring port. Wiring for each MPU and for each actuator must be separately shielded. We also recommend separate shielding for each mA input. Contact inputs may be bundled together within a single multi-conductor cable with one overall shield. Shields should be connected only at the Peak 150 control. Relay and power supply wiring do not normally require shielding.
