一般安装和操作说明及警告该设备适用于I级2类A、B、C和D组（I类，2区，IIC组）或非危险场所。
根据符合EN60079-15，爆炸性环境用电气设备-保护类型“n”这些清单仅限于持有认证的单位识别现场接线必须为额定温度至少为75°C的铜绞线，以便操作预计环境温度将超过50°C。外围设备必须适合其使用位置。
接线必须符合北美I级2类或欧洲2区布线方法（如适用），并符合具有管辖权的当局。
对于船用类型批准的版本，现场接线必须安装接地至外壳的附加屏蔽层。
附加屏蔽超出了手册其他地方所述的标准屏蔽，它可以由实心或柔性金属导管、铠装电缆或带有整体屏蔽的电缆。
一般说明505控制器设计用于控制单或双（分程）致动器汽轮机（抽汽式汽轮机需要505XT版本）。
505是现场可编程，允许单个设计用于多种不同的控制应用程序并减少成本和交付时间。
它使用菜单驱动指导现场工程师将控件编程为特定控件的软件发电机或机械驱动应用。505可以配置为运行作为独立单元或与工厂的分布式控制系统结合使用。
505控制器有五个PID控制器，可以影响进气口的需求蒸汽流入汽轮机；速度/负载PID控制器，辅助PID控制器、辅助2 PID控制器和级联PID控制器。
依靠在505的配置中，这些PID相互之间的交互方式不同。
请参阅本章后面列出的框图，以全面了解PID关系。
另一个PID可用作独立的控制回路，即可选，可用于驱动独立的模拟输出信号（即不驱动蒸汽阀），用于任何单回路辅助控制需要（如密封气体、压盖密封或润滑油压力回路。
使用时隔离PID控制，建议选择“启用回读”配置为隔离PID的模拟输出通道的“故障”选项需要如果输出电路故障检测。默认情况下，模拟输出通道未配置为产生输出电路故障时报警。
505驱动一个或两个汽轮机节流阀来控制一个汽轮机参数，如果需要，根据其他参数限制汽轮机运行参数。然而，一个受控参数通常是速度（或负载），505可用于控制或限制：涡轮进口压力或流量、排气（反）压力或流量、一级压力、发电机功率输出、设备进口和/或出口液位、压缩机入口或出口压力或流量、装置/装置频率、工艺温度或任何其他与汽轮机相关的工艺参数。有关应用的详细信息，请参阅本手册第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.
