一般說明505控制器設計用于控制單或雙（分程）致動器汽輪機（抽汽式汽輪機需要505XT版本）。
505是現場可編程，允許單個設計用于多種不同的控制應用程序并減少成本和交付時間。
它使用菜單驅動指導現場工程師將控件編程為特定控件的軟件發電機或機械驅動應用。505可以配置為運行作為獨立單元或與工廠的分布式控制系統結合使用。
505控制器有五個PID控制器，可以影響進氣口的需求蒸汽流入汽輪機；速度/負載PID控制器，輔助PID控制器、輔助2 PID控制器和級聯PID控制器。
依靠在505的配置中，這些PID相互之間的交互方式不同。
請參閱本章后面列出的框圖，以全面了解PID關系。
另一個PID可用作獨立的控制回路，即可選，可用于驅動獨立的模擬輸出信號（即不驅動蒸汽閥），用于任何單回路輔助控制需要（如密封氣體、壓蓋密封或潤滑油壓力回路。
使用時隔離PID控制，建議選擇“啟用回讀”配置為隔離PID的模擬輸出通道的“故障”選項需要如果輸出電路故障檢測。默認情況下，模擬輸出通道未配置為產生輸出電路故障時報警。
505驅動一個或兩個汽輪機節流閥來控制一個汽輪機參數，如果需要，根據其他參數限制汽輪機運行參數。然而，一個受控參數通常是速度（或負載），505可用于控制或限制：渦輪進口壓力或流量、排氣（反）壓力或流量、一級壓力、發電機功率輸出、設備進口和/或出口液位、壓縮機入口或出口壓力或流量、裝置/裝置頻率、工藝溫度或任何其他與汽輪機相關的工藝參數。有關應用的詳細信息，請參閱本手冊第2卷。
General Installation and Operating Notes and Warnings
This equipment is suitable for use in Class I, Division 2, Groups A, B, C, and D (Class I, Zone 2, Group IIC) or non-hazardous locations. The 505s are suitable for use in European Zone 2, Group II environments per compliance with EN60079-15, Electrical apparatus for explosive atmospheres – Type of protection ‘n’ These listings are limited only to those units bearing the certification identification. Field wiring must be stranded copper wire rated at least 75 °C for operating ambient temperatures expected to exceed 50 °C. Peripheral equipment must be suitable for the location in which it is used. Wiring must be in accordance with North American Class I, Division 2 or European Zone 2 wiring methods as applicable, and in accordance with the authority having jurisdiction. For the Marine Type approved version, the field wiring must be installed with an additional shield layer which is grounded to the enclosure. The additional shielding is beyond the standard shielding described elsewhere in the manual, and it may be made from solid or flexible metal conduit, armored cabling, or a cable with an overall shield.
General Description
The 505 controller is designed to control single or dual (split range) actuator steam turbines (extraction steam turbines require the 505XT version). The 505 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 505 can be configured to operate as a stand-alone unit or in conjunction with a plant’s Distributed Control System. The 505 control has five PID controllers that can affect the demand of the inlet steam flow into the turbine; the Speed/load PID controller, the Auxiliary PID controller, Auxiliary 2 PID controller, and the Cascade PID controller. Depending on the configuration of the 505, these PIDs interact differently with each other. Please refer to the Block diagrams listed later in this chapter to fully understand PID relationships. An additional PID is available as an isolated control loop that is optional and can be used to drive an independent Analog Output signal (that is not driving a Steam Valve) for any single loop ancillary control that may be required (such as Seal Gas, Gland Seals, or lube oil pressure loops. When using the Isolated PID Control, it is recommended to select the “Enable Readback Fault” option for the Analog Output channel configured as the Isolated PID Demand. This will trigger an alarm in the 505 if a fault of the output circuit is detected. By default, Analog Output channels are not configured to produce an alarm when the output circuit has a fault. The 505 drives one or two steam turbine throttle valves to control one turbine parameter at a time, and if desired, limit turbine operation based on other parameters. The one controlled parameter is typically speed (or load), however, the 505 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.
