6、ode 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 505s programmed functionality will appear. Figure 5-2also shows the keys that are active for each screen. The hot keys (Speed, Aux,etc.) are
7、 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
8、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。表5-2 运行模式综述TripControlling parameterRemoteMessagesMessagesMessagesMessages8Messages7Messages4Extemal Trip Input ShutdownDisabledEnter shutdown buttonCo

14、OCP) integrated into one package. The 505s 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
15、 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 505s front panel. However, the turbine can also beoperated remotely. Every front panel control operation can
16、be performedremotely through contacts or Modbus communications. For safety purposes,however, the 505s Overspeed Test function cannot be performed 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
17、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
18、 Run mode.However, from the 505s service 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
19、 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
20、。Starting ProceduresRefer to the turbine manufacturers 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。比较第三章的手册一步一
21、步的配置程序，依靠启动模式下的选择，下面是典型的启动程序（生产过程）。Speed Key ScreensFigure 5-4 shows the possible screens that may appear if the SPEED key ispressed. Only the screens related to the Speed controls programmedfunctionality will be displayed. In addition, the order of the screens may changedepending on the status of t
22、he control. Screens 4, 5 and 6 will always appear. Ifidle/rated is programmed, screen 1 will appear. If the auto start sequence ifprogrammed, screens 2 and 3 will appear. Once the auto start sequence iscomplete, these screens no longer appear.转速键显示表5-4表示可能需要的显示，如按下SPEED键。仅显示与转速控制有关的程序功能补充，那些显示可能会变化，
23、用控制面板开机。4、5、6、总是有显示的。如在空转/额定程序下，1将显示。如在按自动顺序启动程序下2、3、将显示。一次自动运行完成后，这些显示将不在显示。1# -selects rated选择额定 -selects idle选择空转2# YESselects continue auto sequence选择继续自动运行 NOselects halt auto sequence选择停止、中断、暂停自动运行3#-increases speed setpt加速设定;-decreases speed setpt减速设定4# ENTET-direct entry of speed setpt直接确定转速

26、 the select key屏显1仅显示空转/额定的配置和低转速的额定设置。初次在屏显1上设定适当的转速后见屏显4.屏显2$3仅显示自动开机的配置和至额定转速的设置。屏显56仅显示用户动态可调。这(*)表示可调参数去用ADJ调节，这符号必须是在线显示状态下，然后移动选择键进行选择。Idle/Rated StartFor details on the idle/rated startup, refer to Chapter 3. When a RUN commandis issued, the 505 automatically displays the SPEED screen and sh
27、ows theIdle/Rated status. The speed setpoint is instantly set to the actual turbinesspeed. To increase the speed to the programmed Rated Setpt setting, selectthe Rated command. A Rated command can be issued by pressing the frontpanel YES key from the Idle/Rtd screen (screen 1), closing the Idle/Rate
28、dcontact (if programmed) or selecting a Go To Rated command from Modbuscommunications.空载/额定启动空载/额定启动的详细资料，查阅第三章。当发出运行命令时，505自动显示速度和显示空载/额定状态。转速设置点就立即去设置汽轮机的转速。通过程序“Rated Setpt（额定转速设置点）”设置加速，选择额定转速命令。从Idle/Rtd屏显(screen 1)下，额定转速命令的发出可通过按下控制面板YES键，closing the Idle/Ratedcontact (if programmed) or select
29、ing a Go To Rated command from Modbuscommunications.（未用）When the speed setpoint is ramping to the Rated Setpoint setting it can bestopped at any point that is not within a critical speed avoidance band by issuinga Speed Setpt Raise or Lower command. This can be done by pressing theADJUST UP or DOWN
30、from the front panel SPEED screen (screens 1,2,3 or 4),closing a Speed Raise/Lower contact input or selecting Speed Raise or Lowerfrom a Modbus communications link.当转速设置点是按坡度（曲线）时去额定转速设置点设置它时，它能暂停在任一点但不能在临界转速之内避免波动转速设置点升高或降低命令。通过按下控制面板选择SPEED屏显（屏显123或4），closing a Speed Raise升高/Lower降低 contact input输
31、入接点 or selecting Speed Raise or Lower from a Modbus communications link.The Speed setpoint will again ramp to the Rated Speed setting if the Ratedcommand is re-issued. To re-issue the Rated command press the front panelYES key from the Idl/Rtd screen (screen 1), toggle the Idle/Rated contact openand
32、 closed again (if programmed) or select Go To Rated from a Modbuscommunications link.这转速设置点将按坡度去设置额定转速如果额定命令是复位发出。这复位发出额定命令从Idl/Rtd屏显（屏显1）按下控制面板YES键，触发Idl/Rtd触点打开与关闭(if programmed) or select Go To Rated from a Modbus communications link.The Speed setpoint will ramp to the Idle Speed setting upon sta
33、rtup. However,the Idle Speed setting can be re-selected, when conditions allow, (see Chapter3) by pressing the front panel NO key from the Idl/Rtd screen (screen 1), openingthe Idle/Rated contact (if programmed), or selecting Go To Idle from a Modbuscommunications link.这转速设置点将按坡度在启动上去设置空载转速，无论空载转速设置
34、能否重选，当条件允许时，（看第三章）从Idl/Rtd屏显（屏显1）按下控制面板NO键openingthe Idle/Rated contact (if programmed), or selecting Go To Idle from a Modbuscommunications link.Another feature of Idle/Rated function is the Ramp to Rated option which allowsthe Speed setpoint to only move to the Rated Speed setting; Idle is notsele
35、ctable. This feature is configurable in the Service Mode only. When thisfeature is used with the Idle/Rated contact input, closing the contact results导致 in theSpeed setpoint ramping to the Rated Speed setting and opening the contactstops the speed setpoint ramprather than selecting Idle. To continue
36、 rampingto the Rated Speed setting, re-close the contact, press the front panel YES keyfrom the Idl/Rtd screen (screen 1) or select Go To Rated from Modbuscommunications.另外Idle/Rated function的特点是曲线控制额定选项哪个允许转速设置点去仅传送额定转速设置，空载不能先择。这特点是仅在服务模式配置的。当这特点是用户在Idle/Rated接点输入时，闭合触点导致在转速设置点按曲线去额定转速设置与断开触点停止转速设
37、定点曲线宁愿选择空载。继续曲线去额定转速设置，再次接通接点，从Idl/Rtd屏显（屏显1）按下控制面板YES键或select Go To Rated from Modbus communicationsTable 5-2 lists the Idle/Rated status messages that may appear on the front panel display and the meanings of each.桌面5-2列表是Idle/Rated状态信息，可能在面板上显示每一个信息含义。Table 5-2.

39、tAt Rated Spd Speed Setpt is at the rated SetptRtd Inhibited Selection of rated is not allowed不容许选择额定Idle Inhibited Selection of idle is not allowed不容许选择空载The following indications are available through the Modbus links: Ramping toIdle, At Idle, Turbine in Critical Speed Band, Ramping to Rated, and
40、At Rated. Inaddition to these indications, the Idle Speed Setpoint and Rated Speed Setpointanalog values are also available.下列各项表示可以通过在线MODBUS：曲线去空载、空载、汽轮机过临界转速频率、曲线去额定、额定。适当地添加这些指示，空载转速设定点与额定转速设定点模拟值也同样有效。Auto Start SequenceWhen a RUN command is issued, the 505 automatically displays the SPEEDscree
