MOORE 39ACM24BEN输入控制模块
操作员控制面板
505是一个现场可配置的汽轮机控制和操作员控制面板（OCP）集成到一个包中。全面的图形操作员控件面板显示器和键盘位于505的前面板上。
该显示器可以用于配置505，进行在线程序调整，并操作汽轮机/系统。
易于遵循的说明允许操作员查看实际和设置汽轮机运行期间的任何时间点值。
通信505控制器可以直接与工厂分布式控制系统通信和/或人机界面（HMI）控制面板，通过Modbus通信端口。
一个串行端口支持RS-232或RS-485通信使用ASCII或RTU MODBUS传输协议。
两个以太网端口是也可用于在505和a之间通信相同的信息电厂DCS。
其他功能505还提供以下功能：报警的先出跳闸指示和带有RTC时间戳的跳闸事件，10个外部DI跳闸输入，10个报警输入、临界转速避免（3个速度带）、自动启动顺序（热启动和冷启动），带温度输入选项，双速/负载动态，零速度检测、超速跳闸的峰值速度指示，以及单元之间的等时负荷分担（带DSLC-2控制），前馈回路、初始启动时的加速度保护、远程下垂、频率死区。
使用505控制器有三种正常操作模式：配置模式、维修模式和运行模式。
有关用户的更多信息，请参阅第4章进入每种模式所需的级别。
配置模式–此模式用于选择将控件配置为特定涡轮机应用。
在此模式下，控件将强制硬件输入IO LOCK，意味着没有输出将被激活，所有继电器将被激活断电，所有模拟输出信号将为0电流。
一旦控制通常不再需要程序模式，除非涡轮机选项或操作变更。可以随时查看。
登录此模式需要密码。图1-4显示了505阀门需求概览。
级联和辅助PID是可选控制器，如下图所示仅用于PID关系。
在本手册的后面部分，更详细的功能将显示与每个控制回路PID相关的框图。有20个触点输入可用。
前四个默认值如下功能：关闭、复位、提高速度设定值和降低速度设定值。
如果控制用于发电机应用，必须有两个触点输入配置用于发电机断路器和公用电联络断路器。
其余的附加触点输入可用于配置，以实现各种功能控制器离散输入功能如下所示。
在前面板显示屏上还有4个其他键始终可用–启动/停止/重置和调整Up/Down用于升高或降低高亮显示的值。
Operator Control Panel
The 505 is a field configurable steam turbine control and operator control panel (OCP) integrated into one package. A comprehensive graphical operator control panel display and keypad is located on the 505’s front panel. This display can be used to configure the 505, make On-Line program adjustments, and operate the turbine/system. Easy to follow instructions allow operators to view actual and set point values at anytime during turbine operation. Communications The 505 control can communicate directly with plant Distributed Control Systems and/or Human Machine Interface (HMI) control panels, through Modbus communication ports. One serial port support RS-232 or RS-485 communications using ASCII or RTU MODBUS transmission protocols. Two Ethernet ports are also available to communication this same information between the 505 and a plant DCS. Additional Features The 505 also provides the following features: First-Out Trip indication of Alarm and Trip events with RTC time stamp, 10 External DI trip inputs, 10 External Alarm inputs, Critical Speed Avoidance (3 speed bands), Auto Start Sequence (hot & cold starts) with Temperature Input options, Dual Speed/Load Dynamics, Zero Speed Detection, Peak Speed Indication for Overspeed trip, and Isochronous Load sharing between units (with an DSLC-2 control), Feed-forward loop, Acceleration protection at initial startup, Remote droop, Frequency deadband.
Using the 505
The 505 control has three normal operating modes, Configuration Mode, Service Mode and the Run Mode. See chapter 4 for more information about the User Levels required to enter each of these modes. Configuration Mode – This mode is used to select the options needed to configure the control to your specific turbine application. While in this mode, the control will force the hardware into IO LOCK, meaning that no outputs will be active, all Relays will be de-energized, and all Analog output signals will be at 0 current. Once the control has been configured, the Program Mode is typically not needed again, unless turbine options or operation changes. It is available to be viewed at any time. A password is required to log into this mode.An overview of the 505 valve demands is shown in Figure 1-4. The Cascade and Auxiliary PIDs are optional controllers, and are shown in the following diagrams for PID relationship purposes only. Later in this manual, more detailed functional block diagrams will be shown in relative to each control loop PID.
Twenty contact inputs are available. The first four are defaulted for the following functions: shutdown, reset, raise speed set point, and lower speed set point. If the control is used in a generator application, two contact inputs must be configured for use as for a generator breaker and utility tie-breaker. The rest of the additional contact inputs are available for configuration to function as various controller discrete input functions as listed below. On the front panel display there are 4 additional keys that are always available – Start/Stop/Reset and Adjust Up/Down for raising or lowering a highlighted value.
