•3Φ负无功功率需求继电器：三相负无功电力需求检测可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。如果等于或超过负三相无功功率需求的水平，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可激活相应的辅助继电器，但不显示任何信息（用于过程控制）。•3Φ负无功功率需求水平：如果三相无功功率要求为负且等于或超过该设定值，则会出现三相负无功需求警报或过程控制指示。•3Φ视在功率需求继电器：可禁用三相视在功率要求检测，或将其用作报警或过程控制。如果不需要此功能，则设置为OFF。
• 3Φ NEGATIVE REACTIVE POWER DEMAND RELAY: Three-phase negative reactive 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 if the level of the negative three-phase reactive power demand is equalled or exceeded. Selecting AUX1, AUX2 or AUX3 activates the respective auxiliary relay with no message displayed (intended for process control). • 3Φ NEGATIVE REACTIVE POWER DEMAND LEVEL: If the three-phase reactive power demand is negative and equals or exceeds this setpoint, a three-phase negative reactive power demand alarm or process control indication will occur. • 3Φ APPARENT POWER DEMAND RELAY: Three-phase apparent power demand detection can be disabled or used as an alarm or process control. Set to OFF if this feature is not required.
