组态编程 505 / 505E Start-Up Sequences启机顺序 Manual 手动启动 Control speed with the Trip and Throttle(TT) valve until minimum governor speed. 用TT阀控制升速至最小调速器转速。 Fully open the TT valve after minimum governor speed 然后将TT阀全开。 Semi-Automatic 半自动启动 Fully open the TT valve. 将TT阀全开 Control speed with the Valve Limiter until minimum governor speed. 用阀位限制器控制升速至最小调速器转速。 Fully open the Valve Limiter to 100%. 然后将阀位限制器全开。 Automatic 自动启动 Fully open the TT valve. 将TT阀全开 The speed reference and valve limiter will automatically ramp up at the programmed rate to minimum governor speed. 转速给定值和阀位限制器将按组态好的速率上升至最小调速器转速。 Manual Start Mode 手动启动 Automatic Start Mode 自动启动 Semi-Automatic Mode 半自动启动 Start-Up Functions顺序启动功能 Idle to Rated 暖机到额定 Automatic or manually operated.自动或手动操作 Can be set up for back and forth or Idle to Rated only. 可设定为往复式或暖机到额定单方向 Start Sequence 启机曲线 Two Idle Speeds 2个暖机转速 Two Critical Speed Avoidance zones 2个临界转速区 Hot and Cold ramp rates. 热态及冷态升速率 - 热态与冷态之间采用插值 Fully adjustable rates in Configure mode. 组态模式下升速率可调 Service mode (view only) Service模式下只能查看。 Automatic-Sequence Start-up自动升速曲线启动 Speed Control转速控制 Frequency to RPM conversion 频率到RPM转换 Gear Ratio 齿轮速比 Number of teeth 齿数 Dynamics 动态参数 On-Line vs. Off-Line (2 Sets) 在线和离线（2套） Proportional Gain 比例增益 Integral Gain 积分增益 Derivative Response 微分响应 Speed References转速给定值 Speed Setpoints 转速设定值 Setpoints 设定值 Set in Configure 在Configure 模式下设置 Adjustable in Service 在Service模式下可调整 Remote Setpoint 远程设定值 4 - 20 ma Signal 采用4-20mA输入信号 Directly maps to a Speed Reference 直接作用到转速给定值上 High and Low limits 高/低限制 Adjustable from Service Mode 在Service模式下可调整 Critical Bands (2) 临界转速区（2） Will not allow the turbine to remain in a Critical Band 不会停留 Critical Rate -Rate Speed Reference moves in Critical Band 采用临界转速区升速速率 Turbine will shut down if it remains in band for five times the calculated rate. 如果汽机在临界转速区内时间超过其计算时间的5倍，则停机。 Operations 运行方式 Generator vs Mechanical 发电与机械拖动 Generator = Generator 选择发电机应用 Everything else is mechanical 其它均为机械拖动 KW
