Shearing machines are similar to large machines such as bending machines and punching machines. They are machines with high risk factors. In order to reduce deaths, protective devices are installed to protect them. Light curtains are a relatively common protective device. A set of machine light curtain includes a light emitter, a light receiver, a signal cable, a mounting bracket and a light curtain controller, so why should the light curtain of the shearing machine be equipped with a controller? Today I will take you to understand the advantages and importance of the light curtain controller.
If the light curtain is not connected to the controller, the conventional signal output is a high and low level signal, it can be directly connected to the PLC. Because the shearing machine is relatively vibrating, it may affect the light curtain of the light curtain. If the light curtain fails, it is very likely Cause death, but the controller can change this shortcoming. If the light curtain of the matching controller fails, the controller will lock this state in the presence of obstructions and give a signal to the machine. The stoppage of the equipment is the double guarantee of the light curtain protection.
The light curtain controller can solve the factors caused by the loss of the light curtain. It can also monitor the state of the grating. It has a shielding mode. If you don't need the grating to work, you can turn on the shielding mode, and the grating will not work. When customers choose gratings, they must tell the manufacturer what equipment they use, and treat different equipment differently before they can perform nursing work.
