GE DS3800NFCDISIK PC点火电路板
OVERFREQUENCY LEVEL（过频率水平）：当测量的频率等于或超过该设置点设置的水平时，将出现过频率情况。OVERFREQUENCE DELAY（过频率延迟）：如果过频率等于或超出该设置点中编程的时间延迟的OVERFREQUENCY LEVEL（超频率水平）设置值，将出现过频情况。这些设定值范围取决于功率报警水平基本单位设定值。如果功率警报水平基本单位=kW/kVAR，则范围以kW/kVAR为单位。如果功率警报水平基本单位=MW/Mvar，则范围以MW/Mvar功率警报水平基础单位为单位：此设置点用于选择所有功率警报的基础单位乘数。当设置为kW/kVAR时，所有功率警报级别都可以设置为kW和kVAR，阶跃值为1 kW/kVAR。当设置为MW/MVAR时，所有功率警报级别都可以根据MW和MVAR进行设置，阶跃值为0.01 MW/MVAR。
OVERFREQUENCY LEVEL: When the measured frequency equals or exceeds the level set by this setpoint, an overfrequency condition will occur.OVERFREQUENCY DELAY: If the overfrequency equals or exceeds the OVERFREQUENCY LEVEL setpoint value for the time delay programmed in this setpoint, an overfrequency condition will occur.These setpoint ranges are dependent upon the POWER ALARMS LEVEL BASE UNITS setpoint. If POWER ALARMS LEVEL BASE UNITS = kW/kVAR, then the ranges are in kW/kvar. If POWER ALARM LEVEL BASE UNITS = MW/Mvar, then the ranges are in MW/Mvar POWER ALARMS LEVEL BASE UNITS: This setpoint is used to select the base unit multiplier for all power alarms. When set to kW/kVAR, all power alarm levels can be set in terms of kW and kVAR with a step value of 1 kW/kVAR. When set to MW/MVAR, all power alarm levels can be set in terms of MW and MVAR with a step value of 0.01 MW/ MVAR.
