My home automatic rotation of the door is broken, maintenance staff said the structure is unreasonable, slip ring can not be demolished and installed, 12 Road, broken 4 Road, heroes who help out ideas. Thank you
If there is a large revolving door will have a transmission slip ring, slip ring is the movement of the conductive parts, in the rotation process may also produce a false signal, you need to observe the PLC input port to judge.
Solution Check the slip ring whether there is a spare line, usually there is, the line to replace, more trouble.
As long as there are two power supply to ensure that there are two good no problem.
My home automatic revolving door control system (national patent product), only two signal lines through the slip ring, do not know how your slip ring is damaged: is serious wear, the door sink sinking, or water caused by other The road is intact, that is, as long as you have to ensure that there are two power supply, the other two good no problem! You search "Dalian Eno" can be clear.
