ANALOG INPUTS: Changed max setting on the delay time’s tunable range from 3 ms to 3000 ms. The analog input failure delay setting is defaulted to zero but can be adjusted up to 3000msec using the debug mode MAIN.AIx.LATCH_DLY where x is the analog input number. Added a tunable single pole filter (LAG) to each analog input. Output/input = 1/(1+st) where t = 1/(2(pi)f) = LAG_TAU. The Lag-tau is defaulted to zero but can be adjusted in the debug mode using MAIN.AIx_LAG.LAG_TAU where x is the analog input number (1-6). General Description General The 505E is a 32-bit microprocessor-based control designed to control single extraction, extraction/admission, or admission steam turbines. The 505E is field programmable which allows a single design to be used in many different control applications and reduces both cost and delivery time. It uses menu driven software to instruct site engineers on programming the control to a specific generator or mechanical drive application. The 505E can be configured to operate as a stand-alone unit or in conjunction with a plant’s Distributed Control System. Operator Control Panel The 505E is a field configurable steam turbine control and operator control panel (OCP) integrated into one package. A comprehensive operator control panel, including a two- line (24 characters each) display, and a set of 30 keys is located on the 505E’s front panel. This OCP is used to configure the 505E, make OnLine program adjustments, and operate the turbine/system. Easy to follow instructions are presented in English through the OCP’s two-line display and operators can view actual and setpoint values from the same screen.
Turbine Control Parameters The 505E interfaces with two control valves (HP & LP) to control two parameters and limit an additional parameter, if desired. These two controlled parameters are typically speed (or load) and extraction/admission pressure (or flow), however, the 505E could be utilized to control or limit: turbine inlet pressure or flow, exhaust (back) pressure or flow, first stage pressure, generator power output, plant import and/or export levels, compressor inlet or discharge pressure or flow, unit/plant frequency, process temperature, or any other turbine related process parameter. Refer to Volume 2 for details on applications. Communications The 505E 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, or RS-485 communications using ASCII or RTU MODBUS transmission 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.
