1, the oxygen content is greater than 200ppm

Cause: New glove box debugging or false operation.

Method: Stop loop, turn it on, clean it to 100 ppm, turn on the loop.

2, the screen shows that the main valve pressure is less than 0.4MPa or main valve signal fault

Cause: The gas source is insufficient.

Method: ventilation bottle, increase the pressure to 0.4-0.5 mpar.

3, the screen displays “pump switch off”

Cause: The vacuum pump is too large, causing trip.

Method: After repairing the vacuum pump, turn on the electric cabinet and close the trip switch.

4, the cycle can not be opened

Cause: The voltage does not stabilize the inverter protection, resulting in a loop that cannot be turned on.

Method: After the equivalent is stable, restart the glovebox to resolve.

5. When regenerating, the amount of gas is far less than before.

Cause: The organic solvent content in the glove box is too high, and the organic solvent enters the circulatory system during cycle, and the organic solvent is blocked when the organic solvent is blocked.

Method: 1 Change the one-way valve as a straight valve, which is set to 0.03 ~ 0.04 MPa; 2 Observe whether the regenerative gas flowmeter is displayed in 20 ml / min, otherwise adjust the pressure reducing valve pressure.
