GE DS3800HRDB1D1D继电器光学驱动器板
•3Φ正无功功率需求水平：当三相无功功率要求等于或超过该设定值时，将出现三相正无功需求警报或过程控制指示。•3Φ负实际功率需求继电器：三相负实际功率要求检测可以禁用或用作报警或过程控制。如果不需要此功能，则设置为OFF。选择ALARM（报警）将激活报警继电器，并在等于或超过负三相实际功率需求水平时显示报警消息。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负实际功率需求水平：当三相实际功率需求为负并超过该设定值时，将出现三相负实际功率要求警报或过程控制指示。
• 3Φ POSITIVE REACTIVE POWER DEMAND LEVEL: When the three-phase reactive power demand equals or exceeds this setpoint, a three-phase positive reactive power demand alarm or process control indication will occur. • 3Φ NEGATIVE REAL POWER DEMAND RELAY: Three-phase negative real power demand detection can be disabled or used as an alarm or process control. Set to OFF if this feature is not required. Selecting ALARM activates the alarm relay and displays an alarm message whenever the level of the negative three-phase real power demand 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 NEGATIVE REAL POWER DEMAND LEVEL: When the three-phase real power demand is negative and exceeds this setpoint, a three-phase negative real power demand alarm or process control indication will occur.
