When the control is powered up 加电and afterthe brief下达CPU self test自检测has been completed完成, the control displays a ready status就绪状态(Controlling Parameter调节参数/Push Run or Program). The 505’s normal operating正常工作architecture is divided分成into two sections到两部分零件: the Run Mode and the Program Mode. The Program Mode is used to configure the 505 for the specific application专用应用程序andset all operating parameters工作参数(see Chapter 4). The Run Mode is simply仅仅the normal正常turbine operation mode工作操作方式and is used to view operating parameters and run the turbine. A Service Mode预检（服务）模式is also同样available可用to make制做additional另外附加的on-line adjustments调整机构while the unit装置is running. See Volume 2 for information on the Service Mode.505愿意从界面上通过用户的友好界面进行服务与维修。
其基本程序体系结构为离散模拟输入/输出与Modbus通讯（插图说明见5-1）。
当控制电源加电与CPU下达自检测完成后，控制面板显示ready status就绪状态(Controlling Parameter调节参数/Push Run or Program)。
505正常工作体系结构分为两部分，即：the Run Mode and the Program Mode（设置全部的工作参数见第四章）。
运行模式仅为正常工作操作方式与用户去浏览工作参数和启动汽轮机。
预检（服务）模式同样可用需制做另外附加的调整机构，当装置运行时可以在服务模式上看见容积信息。
表5-1基本程序体系结构An overview of Run mode keys and screens is shown in Figure 5-2. This diagramshows all of the potential screens that could appear. However, only the screensthat are related to the 505’s programmed functionality will appear. Figure 5-2also sh ows the keys that are active for each screen. The ‘hot’ keys (Speed, Aux,etc.) are always active if the function is programmed. The ADJUST UP/DOWN,ENTER, YES/NO keys, however, are only active with certain screens. Figure 5-2can be referred to, when determining what keys are active and what screens willappear on the display.运行模式控制键与屏显见表5-2综述，这个图表显示全部的下级屏显并显示出来。
无论如何，屏幕仅显示与505程序功能有关的显示。
表5-2也显示在屏幕上各功能键的功能。
这些热键（Speed, Aux, etc.）总是在组态程序功能后处于激活状态。
那些ADJ（ADJUST调整键）UP/DOWN、ENTER、YES/NO 键、不论何时仅在确定屏显时处于激活状态。
表5-2能够查阅，当决定什么键是激活的和屏幕将要显示什么时。
Keypad and DisplayThe 505 is a field configurable steam turbine control and operator control panel(OCP) integrated into one package. The 505’s service panel consists of a 30-keykeypad and LED display located on the front of the control. The LED display hastwo, 24 character lines that can be used to display operating parameters andtrouble-shoot parameters in plain English. The service panel is used to configurethe 505, make On-Line program adjustments, and operate the turbine/system.No additional panels are required to operate the turbine, every turbine controlfunction can be from the 505’s front panel. However, the turbine can also beoperated remotely. Every front panel control operation can be performedremotely through contacts or Modbus communications. For safety purposes,however, the 505’s Overspeed Test function cannot be pe rformed through aModbus link.键区与显示505汽轮机控制配置范围与操作员控制面板（简称OCP）整合在一个安装包内。
505维护操作面板同由30个键组成，键民LED显示固定在前面板上，国LED有两行显示，可显示24个字符供用户显示工作参数与用浅显的英语进行故障参数检修。
这个面板是用配置505，做在线程序调整，与运行汽轮机系统。
不需要另外附加面板支控制汽轮机，每次汽轮机控制功能可从505控制面板操作。
无论何时汽轮机也能遥控操作。
每次从控制面板操作都能完成任务。
遥控通过接点或MODBUS通讯。
出于安全的目的，无论何时，都不能把超速试验通过连接MODBUS来完成任务。
Run Mode Front Panel KeysFor a detailed description of each 505 key functionality see Chapter 1.Of the thirty front panel keys, not all are active at all times in the Run mode.However, from the 505’s servic e panel, the keys that are active will be apparentsince there is immediate display feedback when an active key is pressed. Whena respective “Hot” key (Aux, Casc, KW, etc.) function is not programmed, aFUNCTION NOT PROGRAMMED message will be appear if the key is pressed.The following are generalizations when determining what keys will function:运行模式下的前面板键从详细的描述至每一个505键的功能见第一章的30个键的控制面板，在运行模式下它们不是总在激活状态下，而是在一定的时间内才可用。
无论何时从505操作面板，那些可用的键总是有显示的，以后那儿有即时反馈显示，当键入活动中的按键时，当各自的热键(Aux, Casc, KW, etc.)功能没有组态时，如果按下此键时，将显示FUNCTION NOT PROGRAMMED信息，以下是通用的当决定什么时候将要键入什么功能时。
Starting ProceduresRefer to the turbine manufacturer’s operating procedures for completeinformation on turbine start up, and Chapter 3 of this manual for a step by stepprocedure, depending on the start mode selected. The following is a typical startupprocedure:起动过程在汽轮机启动前查阅汽轮机厂家的操作程序完善信息。
