In this case, the series resistor should be placed as close to the relay as possible to limit the current when charging the cable capacitance.
在这种情况下,串联电阻就应该尽量靠近继电器,以限制电缆电容充电时的电流。
Respectively through the various contacts, in order to dial the corresponding limit switches and over current relay normally closed contacts, to see the ability to cut off the control current.
①分别接通各个接触器,依次拨通相应的限位开关和过电流继电器常闭触头,查看其切断控制电流的能力。
