There is no air in the pressure regulating valve of the edge banding machine.

First of all, check whether the circuit of the air pressure detection sensor is abnormal and whether the plug falls off. Pressure detection sensors are generally equipped with indicator lights to see if the detection lights are on. If it is on, there is no signal to the controller, or the circuit is abnormal. Second, check whether the set value of the pressure sensor is too large, find the adjustment position and adjust it according to the arrow above. Third, how big is the actual air pressure, and whether the pipeline from the gas path to the pressure sensor is blocked by oil pollution. Whether the pressure alarm parameter setting in the fourth touch screen is too large.
