Especially in the condition that the speed signal device is connected to the power, don't disconnect the connection between PT and the speed signal device. 特别是在转速信号装置接通电源的情况下,勿断开PT与转速信号装置间的连接。
To calibrate the circuit, first disconnect or obscure the input photodiode so that A1A converts no ac signal. 为校准电路,首先断开或使输入光敏二极管变暗,以便A1A转换非交流信号。
The control and logic device receives the control command from the upper controller, and orders the switch device connect or disconnect, Simultaneously, offers the upper controller the status and trip signal according to the state of SSPC and the information from the current-sense device. 控制和逻辑部件从上位机接收控制指令,根据接收的指令激励开关部件断开或闭合,同时依据SSPC的状态和来自电流感受部件的信息,向上位机提供状态和跳闸信号。
