Electric revolving door has been kept non-stop why?
Usually the probe has a sensor swivel, stop switch failed to normal transmission of the signal, in question, plus my network name number, detailed to you
1 Check the door sensor.
The revolving door may generate a signal every revolution, because the rotary door senses the sensor, resulting in a rotating command signal that produces a rotation every day.
Solution: adjust the sensitivity of the sensor, the sensor has the sensitivity of the size of the adjustment knob, reduce the sensitivity, adjust the sensor angle, pay attention to let the sensor out.
2, the above no problem is to check the slip ring
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.
3, special features
Some automatic doors are the function of this often turn.
4, the door position sensor '
If the door of the positioning sensor is also a problem.
Solution, first determine your flat function or lock the door function there is no, if there is no problem here, if there is no need to check the positioning sensor, adjust its gap with the magnet
5 other
Many of the models do not know which one you are using
Some manufacturers are positioned with the encoder, the shield without encoder, KBB has an encoder. Or Qingdao type encoder, other manufacturers of the specific but also on-site inspection
