At this time, the bypass throttle valve supplies air to the positive-pressure cabinet (as preset), stabilizing the pressure inside the cabinet between 100-200Pa (if the pressure is unstable, adjust the throttle valve's lower adjustment nut to adjust the inlet opening until the pressure value stabilizes at a fixed value). At this point, non-explosion-proof instruments can be powered on for operation. During use, if the pressure exceeds 400Pa, the pressure-limiting valve opens to keep the pressure inside the cabinet within the normal working range, preventing high pressure.If the pressure decreases and falls below 50Pa, the system enters an under-pressure alarm state, and the explosion-proof audible and visual alarm light will alarm; if the pressure continues to drop below 25Pa, the system enters a power-off interlock state, and the contactor inside the cabinet automatically cuts off the power to non-explosion-proof instruments in the positive-pressure room, while the explosion-proof audible and visual alarm light continues to alarm. This is the low-pressure protection and electrical interlock process. The alarm sound can be canceled by pressing the "silence" button, but the system state will not change; only changing the pressure can change the system state.If the entire cabinet needs to be powered off for maintenance, all running loads, the positive-pressure room power distribution system, and the automatic control system should be stopped in sequence, and the "inlet manual valve" should be closed. After about 5 minutes, when the pressure inside the positive-pressure room is fully released, the cabinet cover can be opened. For restart, repeat the above steps and perform purging to avoid the risk of flammable gas remaining in the positive-pressure room before power is supplied. The automatic control system box is equipped with a "debug" button, which can be used for full-cabinet power-on commissioning when there is no air source input to the cabinet but the surrounding gas environment is safe.note: Ensure that the surrounding gas environment is safe before using the "debug" button.!！！
