505E还提供以下功能：先出跳闸指示（共5个
跳闸输入）、临界速度避免（2个速度带）、自动启动顺序（热启动）
&冷启动）、双速度/负载动态、零速度检测、峰值速度
超速跳闸指示和机组间的等时负荷分配。
使用505E
505E控制有两种正常操作模式，编程模式和编程模式
运行模式。程序模式用于选择配置所需的选项
该控件适用于您的特定涡轮机应用。一旦控制完成
配置后，程序模式通常不再使用，除非：
选项或操作更改。配置后，运行模式用于运行
汽轮机从启动到停机。除了程序和运行之外
有一种服务模式可用于增强系统运行
当单元运行时。有关维修模式的信息，请参阅第2卷。
505E输入和输出
控制输入
两个速度输入，可跨接配置，用于MPU（磁拾波器
单元）输入或接近探针。
六个模拟输入可用。一个专用于提取/接纳
输入其余五个是可配置的。第六模拟输入具有隔离
并且应用于非隔离的自供电信号。
16个触点输入可用。四个专用于关闭、重置和恢复，

如果控制装置用于电力系统，则专用于发电机断路器和公用设施连接断路器
生成器应用程序。可以配置十个额外的触点输入。如果
该装置不用于发电机应用，则需要12个额外的触点输入
可以配置。
控制面板上的四个功能键。F1和F2专用于
报警和超速测试。F3和F4可用于启用或
禁用控件的各种功能。
控制输出
高压和低压阀的两个带线性化曲线的执行器输出
输出。
六个4–20 mA输出，用于仪表或其他读数。
八个Form-C继电器触点输出，六个可配置。两人都很专注
继电器输出用于停机和报警指示。

The 505E also provides the following features: First-Out Trip Indication (5 total trip inputs), Critical Speed Avoidance (2 speed bands), Auto Start Sequence (hot & cold starts), Dual Speed/Load Dynamics, Zero Speed Detection, Peak Speed Indication for Overspeed trip, and Isochronous Loadsharing between units. Using the 505E The 505E control has two normal operating modes, the Program Mode and the Run Mode. The Program Mode is used to select the options needed to configure the control to your specific turbine application. Once the control has been configured, the Program Mode is typically never again used, unless turbine options or operation changes. Once configured, the Run Mode is used to operate the turbine from start-up through shutdown. In Addition to the Program and Run modes, there is a Service Mode which can be used to enhance system operation while the unit is running. Refer to Volume 2 for information on the Service Mode. 505E Inputs and Outputs Control Inputs Two speed inputs which are jumper configurable for MPU (magnetic pickup units) inputs or proximity probes. Six analog inputs are available. One is dedicated as the extraction/admission input. The remaining five are configurable. The sixth analog input has isolation circuitry and should be used for a self-powered signal that is not isolated. Sixteen contact inputs are available. Four are dedicated for shutdown, reset, raise speed setpoint, and lower speed setpoint. Another two contact inputs must be dedicated for generator breaker and utility tie breaker if the control is used in a generator application. Ten additional contact inputs can be configured. If the unit is not used in a generator application, then twelve additional contact inputs can be configured. Four function keys on the front panel of the control. F1 and F2 are dedicated to alarm and overspeed test, respectively. F3 and F4 can be used to enable or disable various functions of the control. Control Outputs Two actuator outputs with linearization curves for the HP and the LP valve outputs. Six 4–20 mA outputs, for meters or other readouts. Eight Form-C relay contact outputs, six that are configurable. The two dedicated relay outputs are for shutdown and alarm indication.
