Abnormal transmission of safety edge signal includes signal interruption, interference and delay.
Signal interruption is manifested as no response of the device after triggering, due to cable disconnection, connector oxidation, controller interface failure, or broken conductive strip inside the edge.
Signal interference can distort the signal and cause the device to shut down by mistake, which is caused by electromagnetic radiation from nearby high-power equipment, unshielded cables, or poor grounding.
Signal delay refers to slow shutdown after triggering, due to long cables with high resistance, slow controller processing speed, or complex transmission paths with multiple transfer points. These abnormalities affect safety protection and need to be investigated and resolved in a targeted manner.
