正实功率继电器：正实功率电平检测可以禁用，用作报警或过程控制。如果不需要此功能，则将此设置点设置为关闭。选择报警继电器将使报警继电器激活，并在正实际功率水平超过所选水平时显示报警信息。选择辅助继电器将使辅助继电器激活设定的正实际功率，但不会显示任何信息。这用于过程控制。•正实际功率水平：当三相实际功率等于或超过此设定值设置的水平时，将出现过多的正实际功率条件。•正实功率延迟：如果正实功率等于或超过此设置点中编程的时间延迟的正实功率电平设置点值，则会出现过大的正实功情况。
POSITIVE REAL POWER RELAY: Positive real power level detection can either be disabled, used as an alarm or as a process control. Set this setpoint to off if the feature is not required. Selecting alarm relay will cause the alarm relay to activate and display an alarm message whenever a positive real power level exceeds the selected level.Selecting auxiliary relay will cause the auxiliary relay to activate for a set level of positive real power but no message will be displayed. This is intended for process control. • POSITIVE REAL POWER LEVEL: When the three phase real power equals or exceeds the level set by this setpoint, an excess positive real power condition will occur. • POSITIVE REAL POWER DELAY: If the positive real power equals or exceeds the POSITIVE REAL POWER LEVEL setpoint value for the time delay programmed in this setpoint, an excessive positive real power condition will occur.
