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 diagram
shows all of the potential screens that could appear. However, only the screens
that are related to the 505’s programmed functionality will appear. Figure 5-2
also 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 5-2
can be referred to, when determining what keys are active and what screens will
appear 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 Display
The 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-key
keypad and LED display located on the front of the control. The LED display has
two, 24 character lines that can be used to display operating parameters and
trouble-shoot parameters in plain English. The service panel is used to configure
the 505, make On-Line program adjustments, and operate the turbine/system.
No additional panels are required to operate the turbine, every turbine control
function can be from the 505’s front panel. However, the turbine can also be
operated remotely. Every front panel control operation can be performed
remotely through contacts or Modbus communications. For safety purposes,
however, the 505’s Overspeed Test function cannot be pe rformed through a
Modbus 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 Keys
For 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 apparent
since there is immediate display feedback when an active key is pressed. When
a respective “Hot” key (Aux, Casc, KW, etc.) function is not programmed, a
FUNCTION 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 Procedures
Refer to the turbine manufacturer’s operating procedures for complete
information on turbine start up, and Chapter 3 of this manual for a step by step
procedure, depending on the start mode selected. The following is a typical startup
procedure:
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 Screens
Figure 5-4 shows the possible screens that may appear if the SPEED key is
pressed. Only th e screens related to the Speed control’s programmed
functionality will be displayed. In addition, the order of the screens may change
depending on the status of the control. Screens 4, 5 and 6 will always appear. If
idle/rated is programmed, screen 1 will appear. If the auto start sequence if
programmed, screens 2 and 3 will appear. Once the auto start sequence is
complete, 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，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。

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5＆6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 Start
For details on the idle/rated startup, refer to Chapter 3. When a RUN command
is issued, the 505 automatically displays the SPEED screen and shows the
Idle/Rated status. The speed setpoint is in stantly set to the actual turbine’s
speed. To increase the speed to the programmed ‘Rated Setpt’ setting, select
the Rated command. A Rated command can be issued by pressing the front
panel YES key from the Idle/Rtd screen (screen 1), closing the Idle/Rated
contact (if programmed) or selecting a Go To Rated command from Modbus communications.
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 selecting a Go To Rated command from Modbus communications.（未用）
When the speed setpoint is ramping to the Rated Setpoint setting it can be
stopped at any point that is not within a critical speed avoidance band by issuing
a Speed Setpt Raise or Lower command. This can be done by pressing the
ADJUST UP or DOWN from the front panel SPEED screen (screens 1,2,3 or 4),
closing a Speed Raise/Lower contact input or selecting Speed Raise or Lower
from 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 Rated
command is re-issued. To re-issue the Rated command press the front panel
YES key from the Idl/Rtd screen (screen 1), toggle the Idle/Rated contact open
and closed again (if programmed) or select Go To Rated from a Modbus
communications 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 startup. However,
the Idle Speed setting can be re-selected, when conditions allow, (see Chapter
3) by pressing the front panel NO key from the Idl/Rtd screen (screen 1), opening
the Idle/Rated contact (if programmed), or selecting Go To Idle from a Modbus
communications 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opening the Idle/Rated contact (if programmed), or selecting Go To Idle from a Modbus communications link.
Another feature of Idle/Rated function is the ‘Ramp to Rated’ opt ion which allows
the Speed setpoint to only move to the Rated Speed setting; Idle is not
selectable. This feature is configurable in the Service Mode only. When this
feature is used with the Idle/Rated contact input, closing the contact results导致in the
Speed setpoint ramping to the Rated Speed setting and opening the contact
stops the speed setpoint ramp—rather than selecting Idle. To continue ramping
to the Rated Speed setting, re-close the contact, press the front panel YES key
from the Idl/Rtd screen (screen 1) or select Go To Rated from Modbus
communications.
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 communications
Table 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。

The following indications are available through the Modbus links: Ramping to
Idle, At Idle, Turbine in Critical Speed Band, Ramping to Rated, and At Rated. In
addition to these indications, the Idle Speed Setpoint and Rated Speed Setpoint
analog 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 Sequence
When a RUN command is issued, the 505 automatically displays the SPEED
screen (unless used with the Semiautomatic start mode) and shows the Status of
the Auto Start Sequence (screen 2). The Speed setpoint is instantly set to the
turbine’s actual speed and the sequence will continue from this point. This
sequence is automatic, however the sequence can be halted. Halting the Auto
Start Sequence can be performed by pressing the front panel NO key from the
Sequence Status screen (screen 2), opening the Halt/Continue contact (if
programmed), selecting Halt from a Modbus communications link, or selecting
Speed Setpt Raise or Lower. To provide feedback, a relay can be programmed
to indicate the Auto Start Sequence is Halted.
自动启动顺序
当运行命令发出时，505自动显示速度屏（除在半自动启动模式以外）和显示自动启动顺序的状态（屏显2）。转速设置点就开始汽轮机的实际转速与顺序将连续地从这点开始。这是自动启动顺序，无论何时程序都可暂停。暂停自动启动后可在程序状态屏（屏显2）按下控制键NO键，暂停/继续开度（如组态），选择从MODBUS总线暂停，或选择转速设置点升高或降低。按规定反馈，编程后的继电器显示Auto Start Sequence is Halted.自动开机暂停。
The Sequence can be restarted again by pressing the front panel YES key from
the Sequence Status screen (screen 2), closing the Halt/Continue contact, or
selecting Continue from a Modbus communications link. Table 5-3 lists the Auto
Start status messages that may appear on the display and the meanings of each.
