HONEYWELL SPS5785脉冲模块
计量、操作和报警通过单击计量按钮或单击可查看计量、操作和报警屏幕菜单栏上的屏幕并单击计量/操作。计量上显示的信息，通过在查看屏幕时单击计量按钮，或通过以下方式冻结操作和报警屏幕：单击菜单栏上的测光，然后单击禁用测光。可通过单击恢复计量按钮，或单击菜单栏上的计量并单击启用计量。计量，操作和报警屏幕由两个选项卡组成：操作和报警/状态。操作标号操作选项卡计量值、设定值和控制功能如图5-16所示。发电机电压（V）。这些计量值报告了VA-B、VC-B、VCA和VAVG发电机的状态电压。报告的值是在端子E1、E2和E3处感测到的电压与发电机PT比。所有计量值每秒更新一次。当单相感应为使用（系统配置屏幕、感测电压）和DECS-100感测电压端子（E1，E2和E3）如图4-7或4-9所示连接，所有发电机电压计量值将是相同的。运行状态。操作状态控制和指示器包括三个按钮和三个相应的指标。
操作状态按钮标记为PF、VAR和OFF
单击PF按钮将相邻PF指示器的颜色更改为绿色，并使DECS-100保持期望功率因数调节点。功率因数调节点可设置在0.6范围内导致0.6滞后。单击VAR按钮将相邻VAR指示器的颜色更改为绿色，并使DECS-100保持期望的var调节点。可以设置无功调节点在100%吸收到100%生成的范围内。单击“关闭”按钮可更改相邻关闭指示器的颜色为红色，并禁用功率因数和无功调节。工作状态控制装置的操作由跨接触点的状态决定DECS-100 Var/PF控制端子（52J、52K）。当这些触点打开时，工作状态控件已启用。闭合端子52J和52K处的触点将禁用工作状态控制和中断VAR或功率因数的调节，直到触点再次打开。
设定值-电压（V）。该设置字段可用于输入所需的发电机输出端子电压电压设定值也可以在设置调整屏幕、设定值选项卡、或其他位置输入，自动电压调节器（AVR）-AVR设定点（V）。以下情况下，此字段的背景色为绿色：在AVR模式下运行，功率因数和无功调节被禁用。设定值-电流（A）。该设置定义了在FCR模式下运行时的磁场电流设定值。这个电流设定值也可在设置调整屏幕、设定值选项卡、现场电流中输入调节器（FCR）-FCR设定点。可以以0.01的增量输入0到7 Adc的电流值Adc。在FCR模式下操作时，该字段的背景颜色为绿色。
Operating Status. The Operating Status controls and indicators include three buttons and three corresponding indicators. Operating Status buttons are labeled PF, VAR, and OFF. Clicking the PF button changes the color of the adjacent PF indicator to green and causes the DECS-100 to maintain the desired power factor regulation point. The power factor regulation point can be set within the range of 0.6 lead to 0.6 lag. Clicking the VAR button changes the color of the adjacent VAR indicator to green and causes the DECS-100 to maintain the desired var regulation point. The var regulation point can be set within the range of 100 percent absorb to 100 percent generate. Clicking the OFF button changes the color of the adjacent OFF indicator to red and disables power factor and var regulation. Operation of the Operating Status controls is determined by the status of the contacts connected across the DECS-100 Var/PF Control terminals (52J, 52K). When these contacts are open, the Operating Status controls are enabled. Closing the contacts at terminals 52J and 52K disables the Operating Status controls and interrupts regulation of vars or power factor until the contacts are opened again. Setpoint - Voltage (V). This setting field can be used to enter the desired generator output terminal voltage. The voltage setpoint can also be entered at the Setting Adjustments screen, Setpoint tab, Automatic Voltage Regulator (AVR) - AVR Setpoint (V). The background color of this field is green when operating in AVR mode and power factor and var regulation is disabled. Setpoint - Current (A). This setting defines the field current setpoint when operating in FCR mode. The current setpoint can also be entered at the Setting Adjustments screen, Setpoint tab, Field Current Regulator (FCR) - FCR Setpoint. Current values from 0 to 7 Adc may be entered in increments of 0.01 Adc. The background color of this field is green when operating in FCR mode.
