What is the cause of the decline of the electric gourd by pushing up or down the button?
That's always the case. If you do, you can see if you've got the wrong line
You should not contactor control, through A button should be A phase B phase C phase another button is A phase C phase B phase, and see if it is all in phase, resulting in A decline in only cannot rise
First, see if there is any fault in the rising contactor, see if the control coil is loose or burnt, and then see if there is any loose connection. There is something wrong with the handle or handle
Pushing up or down the button is the reason for the drop: It's going to go up and down the line between the two contacts, Because the wiring is caused by the power phase sequence cannot be changed. The solution: The two lines of the three-phase line will be switched.
