Three strokes teach you how to solve the problem that the reducer can't start normally.

The first is to first check whether the power supply of the AC relay and the thermal protection relay is normal. If there is an abnormal problem, then it is necessary to check the power supply and restore the normal power supply of the power supply.

The second is to detect the damage or wear of the AC relay winding coil, and then check whether the magnet is rusted. If it is, the magnet will be rusted during the actual maintenance. If the coil is found to be damaged, it must be replaced in time.

The third is to detect the short circuit of the winding of the AC relay at the end. If there is no short circuit condition, continue to detect whether the wiring contact of the thermal protection relay is unblocked. If there is a short circuit condition, repair the AC relay directly, so that the contact can be in good contact. .
