What to do if the operation failure of the variable frequency electric chain hoist is not reflected
In daily life, there are often users who forget to press the button or forget to turn on the power when using the electric hoist, causing the equipment to malfunction. In addition to the above forgotten situations, what other situations will cause the equipment to malfunction?
1: It is caused by internal short circuit or poor contact of the brake switch. In this case, a special electric test is required to check where the short circuit is found. Only when the circuit is confirmed that there is no fault can it be put into use.
2: The rated voltage is not connected. At this time, we can use a voltage or a multimeter to test.
3: The power cord is connected to the wrong phase, and the phase protection function will start after the frequency conversion chain electric hoist is connected to the wrong phase. The solution only needs to reverse the two phases.
4: Check if the fuse of the power supply is burned out, if it is necessary to replace the fuse immediately.
5: The electric hoist motor makes a sound, but it never starts. It is necessary to check whether the phase is accurate, maintain it well and make a good insulation method.
The above 5 points are the ways to deal with the operation failure of the variable frequency electric chain hoist we have explained for you. Hope it will be helpful to your work.
