GE DS3800HSAA1U1N伺服电路板
相位A/B/C/N电流需求继电器：相位/中性点电流需求检测可以禁用或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OFF。选择报警继电器激活报警继电器，并在相/中性电流需求水平等于或超过时显示报警信息。选择AUX1、AUX2或AUX3继电器将激活相应的辅助继电器，但不显示任何信息。这用于过程控制。•阶段A/B/C/N电流需求水平：当阶段A/B/C/C/N电流需求等于或超过此设定值时，阶段A/B/C/N需求警报或过程控制指示出现3Φ正实功率需求继电器：三相正实功率功率需求检测可以禁用或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OFF。
PHASE A/B/C/N CURRENT DEMAND RELAY: Phase/neutral current demand detection can either be disabled or used as an alarm or process control. Set this setpoint to OFF if the feature is not required. Selecting alarm relay activates the alarm relay and displays an alarm message whenever a phase/neutral current demand level is equalled or exceeded. Selecting AUX1, AUX2 or AUX3 relay activates the respective auxiliary relay with no message displayed. This is intended for process control. • PHASE A/B/C/N CURRENT DEMAND LEVEL: When the phase A/B/C/N current demand equals or exceeds this setpoint, a phase A/B/C/N demand alarm or process control indication occurs.• 3Φ POSITIVE REAL POWER DEMAND RELAY: Three-phase positive real power demand detection can either be disabled or used as an alarm or process control. Set this setpoint to OFF if the feature is not required.
