Sharing is the greatest support, and following is the best encouragement 1. Calibration of the “Zero Point” After preheating the sensor for 20 minutes, connect the sensor’s gas chamber to the air sample bag using a rubber hose → Use the remote control to set the sensor to the “zero display interface” → Open the … Read more
【Introduction】Anyone working as an electrician knows that when equipment suddenly shuts down, the most frustrating task is troubleshooting external faults: measuring a bunch of sensors, solenoids, and wiring repeatedly, checking from the power supply to the load, only to find after half an hour that it was a broken wire on the proximity switch. This … Read more
Overview: Why can standardized programs reduce 80% of fault misjudgments? In automated production lines, the alarm system is the “language” of human-machine interaction: a flashing red light indicates an emergency fault, a yellow light represents a warning state, and a steady green light is a “reassurance signal” that the equipment is functioning normally. However, in … Read more
