Positive pressure explosion-proof containers usually have 3 modes：Automatic mode, Bypass mode, Manual mode.
Check the functions of all modes, and the functional tests of all modes will be carried out one by one according to the regulations on the FAT file.
Automatic mode: normal use in hazardous areas
