Case Analysis Of Failure Of Magnetic Induction Switch Of Rodless Cylinder
Publish Time: Author: Site Editor Visit: 22
Generally speaking, the principle of the Rodless Cylinder magnetic induction switch is that a magnet is installed in the cylinder. When the rodless cylinder is in this position, the magnet provides a signal to the magnetic induction switch, thereby turning on the magnetic induction switch. So, let's take a look at the rodless cylinder magnetic induction switch failure case analysis!
The reason for the failure of the rodless cylinder magnetic induction switch is that after the cylinder arrives, the magnetic induction switch is not lit and there is no output. The reasons are generally as follows.
1. There is a problem with the wiring. The magnetic induction switch is divided into three-wire and two-wire types, please pay attention to the wiring
2. The installation position of the cylinder magnetic switch is not installed at the position of the cylinder magnet. In this case, just move the position of the cylinder magnet.
3. When the cylinder magnetic induction switch is damaged, replace it and perform a new fault diagnosis.
4. There is also a special case. I encountered this situation. The rodless cylinder magnetic sensor switch is also on. When you detect the signal, although there is also an output, it occasionally sends a signal that cannot be triggered. The phenomenon is sometimes that the equipment suddenly stops during operation and there is no alarm. However, if the position of the magnetic sensor switch is manually moved, the device will start again from the bright place to the bright place (or the cylinder is manually pulled out and retracted, and the automatic mode is tried. This method must be supported by the program). In this case, please replace the cylinder magnetic induction switch. The equipment is operating normally and has been in operation for about 4 months. Repeat the program inspection and compare the same program and equipment. There is no magnetic induction of the cylinder, but the rising signal in the PLC cannot be triggered (both the rising and falling edges send signals instantly. Finally, replace the cylinder magnetic induction switch for fault diagnosis)
The above is an analysis of the failure case of the rodless cylinder magnetic induction switch. Since there is no need to set the pilot valve and its mounting bracket at both ends of the rodless cylinder stroke, and there is no need to set the baffle at the piston rod end, it is easy to use, compact, reliable, low cost, fast switch response time, and wide response.
