第六部分 505服务模式.ppt

Service 模式 505 / 505E Speed Control 转速控制 Speed Setpoint rates 转速设定值的速率 Rate to minimum governing speed(pgm) 到最小调速器转速的速率 Slow rate(pgm) 慢速率 Fast rate delay 快速率延时 Fast rate(3xslow rate) 快速率 Entered rate(Slow rate) 键盘直接键入设定值时的速率 Underspeed Setting 欠转速设定 Only used if an underspeed relay is programmed. 仅当组态了欠转速继电器时才可用 Defaulted to 100 RPM below the minimum governing speed. 默认值为最小调速器转速-100 RPM Derivative Ratios 微分系数 Hold Changes? 保持改变？ The “Hold xxxx Changes?” must be set to yes to keep the Service Mode changes active. Otherwise the 505 will default to the Configure Mode defaults the next time the 505 is powered up. 为将在Service模式下的改动保存，必须将“Hold xxxx Changes?” 设为YES。否则，下次505通电时，将用Configure模式下的值作为默认值。 Alarm Adjustments报警调整 Does Trip cause Alarm relay to go active? (yes) 停机是否动作报警继电器？ Blink Alarms? (no) 报警是否闪烁？ Used for multiple alarms 用于多个报警 Blinks when an alarm occurs and has not been acknowledged. 某个报警发生后，如未确认，则闪烁。 Remains active until alarm condition no longer exists. 处于激活状态直至报警条件消失。 Jump to Alarm Screen? (no) 跳转到报警屏？ The two line display automatically displays the alarm screens whenever a new alarm occurs. 当新报警发生时，两行显示器自动显示报警屏。 Key Options 键选项 Stop? (yes) 正常停机键？ When set to no - the controlled stop button on the 505 keypad will not function. 设为NO时，505键盘上的控制停机键STOP不起作用。 Dynamics? (yes) 动态参数键？ When set to no - the dynamics of all the control loops will no longer be adjustable in the “Run” mode. 设为NO时，所有控制回路的动态参数在RUN模式下均不可调整。 Speed Droop Options转速有差率选项 Droop % (pgm) 转速不等率 KW vs position? (pgm) 采用功率不等率？ KW vs MW ? 单位是MW？ Used only for display purposes. 仅用于显示。 MPU Timer Options转速超越记时选项 Use the MPU Override timer? (no) 采用转速超越记时 When set to yes - the 505 will issue a shutdown if the timer expires before speed is detected. 设置为YES时，如果在预定时间内没检测到转速，505将输出停机。 Override Time? (600 seconds) 超越时间间隔 Override On? 超越投入？ Indicates the status of the Override only. 仅指示是否处于超越状态 Not adjustable. 不可调 Auto Start自动启机 The auto start sequence screen is for status only. It will display the ramp
