The electric hoist does not work after pressing the start switch
< br >
Because the hoist is not connected to the rated operating voltage, it cannot work in 3 cases:
< br >
1, whether the power supply system for the electric hoist power supply, generally use the test pen test, such as no power supply, such as power supply and then work;
< br >
2, hoist main, control circuit electrical damage, line disconnection or poor contact, will also make hoist motor can not power, this situation, need to overhaul the main, control circuit, overhaul, in order to prevent the main, control circuit to the three-phase motor power supply phase and burn the motor, or hoist motor suddenly run, produce harm, be sure to disconnect the hoist motor from the power line, Only power the main and control circuits, and then click the start and stop switch, check and analyze the working condition of the control electrical appliances and lines, repair or replace the electrical appliances or lines with problems, and restart the test when it is confirmed that the main and control circuits are fault-free;
< br >
3, hoist motor end voltage lower than the rated voltage of more than 10%, the motor starting torque is too small, so that the hoist lifting does not move the goods, and can not work, check, use a multimeter or voltmeter to measure the motor input terminal voltage, because the voltage is too low, so that the motor can not start, need to wait for the system voltage to return to normal after the use of electric hoist.
Common fault one, the transmitter LED light is not bright, the receiver does not respond at all.

The correct approach is as follows:
1. Check whether the battery power supply is normal.
Check the battery installation direction, the direction in which the battery box is installed, and the battery level.
2. Confirm whether the micro-processing control unit is faulty.
First unplug the transmitter key, and then plug the key switch in again; Do not press the \"Start\" button, directly press the \"up, down\" and other action keys, the transmitter should quickly flash a red light indicating that the startup mode is wrong. If no, the microprocessor control unit is faulty or the power cable is improperly connected.
3, if the above can not solve the problem, then send to send repair.
