| Problem / Phenomenon | Reason | Solution |
| Glovebox Alarm Message: ‘02 valve can’t open’ Circulation button on screen is green but the blower is not working (O2 and H2O increasing slowly) | Working gas pressure is too low to open the circulation valves | Check the working gas supply pressure. Set the working gas pressure to 60 – 80 psi. |
| Glovebox Alarm Message: ‘ 03 blower is protected ’ and Frequency Converter Shows Error Code: ‘ F004 ’ Circulation button on screen is green but the blower is not working (O2 and H2O increasing slowly) | Power supply issue from power outage or unstable power supply | Reset the frequency converter located electrical cabinet by press the red reset button and restart thecirculation 
|
| Clicking Sound while Large Antechamber is Refilling | The pressure inside the glovebox main chamber is too low to supply the large antechamber chamber | Set glovebox main chamber pressure to +3 to +7 mbar or
boost from foot pedal |
| Glovebox Main Chamber Can’t Refill | Working gas pressure is too high which causes electro-pneumatic valve not able to open | Close the working gas supply regulator completely and
manually release the pressure by disconnect the
connection between the gas hose and glovebox. Then set
working gas pressure to 60 – 80 psi. |
| Large or Small Antechamber can’t Refill | The refill gas line between main chamber and antechamber is clogged. | Try to see if there is something clogged the refill gas line. |
| Large Antechamber Can’t Evacuate | a. Working gas pressure is too low which causes the electrical-pneumatic valve behind the large antechamber unable to open.
b. Antechamber door is not closed properly. Or the gasket on the door is loose. | a. Set working gas pressure to 60 – 80 psi
b. Check seals and connections.
Check if the door is closed properly.
Check if the antechamber door gasket is loose. Perform
antechamber leak test. |
| Circulation and Analyzer Shut off Suddenly | Pressure inside the glove box is over +15 mbar which was caused by reaching into the glovebox too fast. | Move slowly while using the gloves. Do not insert your
hand too quickly into the gloves. |
| Purge Valve Open and Close Frequently | Glovebox main chamber pressure is too low to control the purge valve and stay open. | Set the working gas pressure to around 60 psi during
purging. |
| Box Pressure keep increasing during “Purging” | Working gas pressure too high. | Maintain the box pressure around +1m bar (below +5mbar)
and working gas regulator pressure: 60~80psi. |
