Mode: Including self-diagnosis, power off self-start features, with pressure control and adaptive functions. Automatic control, cycle control, password protection, vacuum chamber control using LCD display. The unit is controlled by Siemens PLC touch screen. 3.2. Pressure control: Control the pressure of the box and the transition chamber at a certain set value. a) The user can arbitrarily set the working pressure range between +12.5 and -12.5 mbar, and the PLC will automatically adjust the pressure of the box within the set range. The default value of the operating pressure range is -1 to +3 mbar. b) When the box pressure is greater than 12 mbar, the PLC automatically opens the safety valve to relieve the pressure and protect the gloves, equipment and materials in the box. c) Use the foot switch to fine-tune the tank pressure. 3.3. Foot pedal: can control the pressure of the glove box, easy operation.   4. Circulation system (including purification and regeneration system) 4.1.
