Safety light curtain common fault analysis
- Jul 09, 2018 -

At present, safety light curtains are widely used in safety production as safety protection products, and play a vital role in protecting workers and machinery. In the process of installing and using the safety light curtain, there are often some problems. The following is a detailed analysis:


The first is the problem of light. The safety light curtain can't work normally. The most common problem is the light problem. The specific performance is that the red light on the safety light curtain receiver is on. Again, the interference problem is manifested in the case that the safety light curtain is connected to the normal line of the light, the controller is normal, and the fault indicator is strobed. The possible cause of this situation is that there is a large interference around the safety light curtain or there is interference in the ground of the equipment. If you need to check whether the transmission line of the safety light curtain is placed next to the motor, inverter, etc. with interference, remove the ground wire on the controller wiring device and check whether the safety light curtain is back to normal. In the end, the damage of the components, in the normal situation of the light, the controller still shows the fault, there are three reasons for this: one is the transmitter or the receiver has a problem, the most direct way is to check the red color of the safety light curtain Fault indicator. One is that there is a problem with the transmission line. Another is that there is a problem with the controller. If the indicator light of the safety light curtain is green, the problem of the safety light curtain can be eliminated, but the problem of the open circuit of the lower end of the light curtain is not excluded. If you are unable to determine which part is causing the problem, you can replace the safety light curtain, signal cable, controller, and check the status of the controller's normal and fault indicators to determine the problematic part.
