电动机不能启动

Motor does not start

1．电源不通

Disconnected to power supply

2． 操 作 回 路 不 通Control circuit is dead

3．行程或力矩控制器开关动作Switches of limit or torque act.

1．接通电源

Check power supply

2．排除回路故障

Circuit troubleshooting

3．解除动作开关

Eliminate the action of switches.

2

输出轴旋向与

规定要求相反

Motor is overheated

电机电源相序不对

Phase of motor power is not in right phase sequence

三相线中任意对调二相

Exchange any two of three phase

3

电机过热

Motor is overheated

1．连续试车时间过长

Too long a time to continue operating

2．电装与阀门选配不当Motordoes not mate with the

actuator

3．电机二相运转One phase is off
