GE DS3800HPTK1D1F涡轮机控制门驱动板
如果三相视在功率需求水平等于或超过，选择ALARM（报警）将激活报警继电器并显示报警信息。选择AUX1、AUX2或AUX3将激活相应的辅助继电器，但不显示任何信息。这用于过程控制。•3Φ视在功率需求水平：当三相视在功率要求等于或超过该设定值时，将出现三相视在电力警报或过程控制指示。•脉冲输入1继电器：任何PQM开关输入均可分配给计数脉冲输入，如第31页第4.3.4节：开关输入所示。如果编程水平等于或超过，该设定点可用于给出指示（报警或控制）。如果不需要此功能，则将此设置点设置为OFF。每当脉冲计数水平等于或超过所选水平时，选择ALARM（报警）将使报警继电器激活并显示报警信息
Selecting ALARM activates the alarm relay and displays an alarm message if the three-phase apparent power demand level is equalled or exceeded. Selecting AUX1, AUX2 or AUX3 activates the respective auxiliary relay with no message displayed. This is intended for process control. • 3Φ APPARENT POWER DEMAND LEVEL: When the three-phase apparent power demand equals or exceeds this setpoint, a three-phase apparent power alarm or process control indication will occur.• PULSE INPUT 1 RELAY: Any of the PQM switch inputs can be assigned to count pulse inputs as shown in Section 4.3.4: Switch Inputs on page –31. This setpoint can be used to give an indication (alarm or control) if the programmed level is equalled or exceeded. Set this setpoint to OFF if the feature is not required. Selecting ALARM will cause the alarm relay to activate and display an alarm message whenever a pulse count level equals or exceeds the selected level
