產品詳情內容介紹
MOORE 39ACM24BEN輸入控制模塊
操作員控制面板
505是一個現場可配置的汽輪機控制和操作員控制面板（OCP）集成到一個包中。全面的圖形操作員控件面板顯示器和鍵盤位于505的前面板上。
該顯示器可以用于配置505，進行在線程序調整，并操作汽輪機/系統。
易于遵循的說明允許操作員查看實際和設置汽輪機運行期間的任何時間點值。
通信505控制器可以直接與工廠分布式控制系統通信和/或人機界面（HMI）控制面板，通過Modbus通信端口。
一個串行端口支持RS-232或RS-485通信使用ASCII或RTU MODBUS傳輸協議。
兩個以太網端口是也可用于在505和a之間通信相同的信息電廠DCS。
其他功能505還提供以下功能：報警的先出跳閘指示和帶有RTC時間戳的跳閘事件，10個外部DI跳閘輸入，10個報警輸入、臨界轉速避免（3個速度帶）、自動啟動順序（熱啟動和冷啟動），帶溫度輸入選項，雙速/負載動態，零速度檢測、超速跳閘的峰值速度指示，以及單元之間的等時負荷分擔（帶DSLC-2控制），前饋回路、初始啟動時的加速度保護、遠程下垂、頻率死區。
使用505控制器有三種正常操作模式：配置模式、維修模式和運行模式。
有關用戶的更多信息，請參閱第4章進入每種模式所需的級別。
配置模式–此模式用于選擇將控件配置為特定渦輪機應用。
在此模式下，控件將強制硬件輸入IO LOCK，意味著沒有輸出將被激活，所有繼電器將被激活斷電，所有模擬輸出信號將為0電流。
一旦控制通常不再需要程序模式，除非渦輪機選項或操作變更。可以隨時查看。
登錄此模式需要密碼。圖1-4顯示了505閥門需求概覽。
級聯和輔助PID是可選控制器，如下圖所示僅用于PID關系。
在本手冊的后面部分，更詳細的功能將顯示與每個控制回路PID相關的框圖。有20個觸點輸入可用。
前四個默認值如下功能：關閉、復位、提高速度設定值和降低速度設定值。
如果控制用于發電機應用，必須有兩個觸點輸入配置用于發電機斷路器和公用電聯絡斷路器。
其余的附加觸點輸入可用于配置，以實現各種功能控制器離散輸入功能如下所示。
在前面板顯示屏上還有4個其他鍵始終可用–啟動/停止/重置和調整Up/Down用于升高或降低高亮顯示的值。
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.
