GE DS3800DLIB1B1B PLC控制器卡件
Vab、Vbc、Vca MAXIMUM：显示最大线路电压幅值及其发生的时间和日期。该信息存储在非易失性存储器中，并在失去控制电源期间保留。S1 PQM设置\清除数据\清除最小/最大电压值设置点清除这些值。V U/B MAXIMUM（最大值）：显示最大电压不平衡及其测量时间和日期。该信息存储在非易失性存储器中，并在失去控制电源期间保留。用S1 PQM SETUP\CLEAR DATA\CLEAR MIN/MAX VOLTAGE VALUES（S1 PQM设置\清除数据\清除最小/最大电压值）设定值清除该值。Va PHASOR:显示Va幅值和角度的相量表示。Va用作所有其他相量角度的参考。如果PQM电压输入端没有电压，则Ia将用作所有其他角度的参考。在模拟模式下，Va也用作参考。
Vab, Vbc, Vca MAXIMUM: Displays the maximum line voltage magnitudes and the time and date of their occurrence. This information is stored in non-volatile memory and is retained during loss of control power. The S1 PQM SETUP \ CLEAR DATA \ CLEAR MIN/ MAX VOLTAGE VALUES setpoint clears these values. V U/B MAXIMUM: Displays the maximum voltage unbalance and the time and date of its measurement. This information is stored in non-volatile memory and is retained during loss of control power. The value is cleared with the S1 PQM SETUP \ CLEAR DATA \ CLEAR MIN/MAX VOLTAGE VALUES setpoint.Va PHASOR: Displays a phasor representation for the magnitude and angle of Va. Va is used as a reference for all other phasor angles. If there is no voltage present at the PQM voltage inputs, then Ia will be used as the reference for all other angles. Va is also used as the reference when in Simulation Mode.
