Commissioningmethod

Pay AttentionMachineCommissioning:ConfigureBrilliantAir SourceAfter-sales，WeldingVentilationpower supply。Fully open the inlet valve, press the "Start" button to open the inlet solenoid valve, and the 30-minute countdown begins, entering the ventilation state.。After the 30-minute ventilation period ends, when the pressure value exceeds 100 Pa, the sensor detects the pressure value inside the positive pressure chamber and displays it on the system window. The inlet solenoid valve closes, and air is supplied to the cabinet through the solenoid valve bypass throttle valve, maintaining the pressure gauge between 200~300 Pa, meaning the entire cabinet enters automatic operation state. At the same time, power is supplied to the "contactor" inside the positive pressure chamber, enabling the main circuit to operate normally, thus completing the debugging of the explosion-proof positive pressure cabinet.。

During the use of the explosion-proof positive pressure cabinet, when the pressure drops below 100 Pa, the explosion-proof alarm light activates, entering the under-pressure alarm state; when the inlet fault is not resolved and the cabinet pressure drops below 50 Pa, the automatic control system will cut off the main power supply of the positive pressure chamber; the system remains in the under-pressure alarm state (pressing the "mute" button can release it); this is the low-pressure protection and electrical interlock process.。

When the pressure in the positive pressure chamber exceeds 400 Pa, the pressure limiting valve opens, and after a period of time, the pressure in the positive pressure chamber gradually decreases, keeping the pressure inside the cabinet within the normal pressure range, and the valve closes.。

OutputFactoryWhenLocationsWithparameterallalreadyEquipmentStable，Strictly ProhibitUserExpertSelfGreaterModification。During user debugging, attention should be paid to whether the instruments, automatic control lines, and sampling pipelines are unobstructed.。

1. During transportation and installation of the explosion-proof positive pressure cabinet, inspection must be strictly carried out in accordance with the inspection and debugging standards for low-voltage complete equipment.。

2. Check and operate item by item according to the technical accessories accompanying the explosion-proof positive pressure cabinet (such as assembly drawings) and the user's design drawings.。

After debugging is completed, it can be put into use.。
