The 505E control is packaged in an industrial hardened enclosure designed to be mounted within a system control panel located in a plant control room or next to the turbine. The control’s front panel serves as both a programming station and operator control panel (OCP). This user-friendly front panel allows engineers to access and program the unit to the specific plant’s requirements, and plant operators to easily

start/stop the turbine and enable/disable any control mode. Password security is used to protect all unit program mode settings. The unit’s two-line display allows operators to view actual and setpoint values from the same screen, simplifying turbine operation.

Turbine interface input and output wiring access is located on the controller’s lower back panel. Unpluggable terminal blocks allow for easy system installation, troubleshooting, and replacement.

Cost‐Effective Design

The 505E control is designed to function as the turbine control, system sequencer, operator control panel, and first-out indicator. This encompassing design minimizes external system devices as well as system installation, wiring, and troubleshooting. This field configurable controller allows major functional changes to be made at site, often by knowledgeable plant personnel, and minor functional changes to be on-line as process changes require. The 505E control’s first-out-indicator logic indicates internal as well as external system related alarm and shutdown conditions, greatly simplifying and reducing system troubleshooting.

Communications

The 505E controls can communicate directly with plant Distributed Control Systems and/or CRT-based operator control panels, through two Modbus® * communication ports. These ports support RS-232, RS-422, and RS-485 communications using ASCII or RTU Modbus protocols. Communications between the 505E and a plant DCS can also be performed through hardwired connections. Since all 505E PID setpoints can be controlled through analog input signals, interface resolution and control is not sacrificed. *—Modbus is a trademark of Schneider Automation Inc.

Control Accessories

Control Assistant (Configuration Management Tool)

The Woodward Control Assistant software program is a computer-based service tool that can be used with the 505E control to upload, save, and download controller configurations. Optionally, this service tool can also be used to trend unit parameters, to compare differences in configuration files, and to verify if control settings have been changed.
