GE DS3800HSHA1B1A数字量输入卡件
如果功率因数引线1/2继电器设定值设置为AUX1、AUX2或AUX3，则相应的辅助继电器将停用。•功率因数滞后1/2继电器：功率因数检测可以禁用，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。当功率因数滞后于设定的水平时，选择报警继电器将使报警继电器激活并显示报警信息。当功率因数等于或大于设置的电平滞后时，选择AUX1、AUX2或AUX3继电器激活相应的辅助继电器，但不会显示任何信息。这用于过程控制。在该功能运行之前，所有电压输入端必须至少施加20 V电压。•功率因数滞后1/2拾取：当滞后功率因数等于或超过此设置点设置的水平时，将出现功率因数滞后/2情况
If the POWER FACTOR LEAD 1/2 RELAY setpoint is set to AUX1, AUX2, or AUX3, the respective auxiliary relay will deactivate. • POWER FACTOR LAG 1 / 2 RELAY: Power factor 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 when the power factor is more lagging than the level set. Selecting AUX1, AUX2, or AUX3 relay activates the respective auxiliary relay when the power factor is equal to or more lagging than the level set, but no message will be displayed. This is intended for process control. A minimum of 20 V applied must exist on all voltage inputs before this feature will operate.• POWER FACTOR LAG 1 / 2 PICKUP: When a lagging power factor equals or exceeds the level set by this setpoint, a power factor lag 1/2 condition will occur
