1 Trouble Shooting

• Check all displays.

1.1 Problem: The compressor does not start even though power is connected

1. Check if the On/Off Switch is set to ON.
2. Check if the pressure and/or flow display in the front are illuminated and the LCD shows data. (picture 3.1)
3. Check the pressure inside the device's pressure tank. (picture 3.1)

• If the LCDs are illuminated and show data and the pressure is higher than ambient pressure, then this is normal behavior. The compressor will start, once the pressure inside the tank falls below a configured limit.

• If the switch is set to On, but the LCDs remain dark and show nothing, the internal fuse might be dead. Open the device and replace the fuse. Some devices store a replacement fuse inside. See Technical Data

1.2 Problem: The compressor does not provide the necessary pressure

1. Check the pressure sensor display.
   • confirm the compressor stops once the pressure gauge has reached .650 MPa (6.5 bar).
2. Check the flow sensor display.
   • confirm the maximum flow-rate shown, right before compressor stops and the value reverts to 0, is approximately 1.0 L/min to 1.4 L/min.
3. Check the tubes connected to the device for leaks and good fit.

• The tubes connected to the NitroPro Go, might be loose and loosing pressure.
• The pressure controller might have lost it's configure. Contact support.
• There might be a leak internally. Contact support.

1.3 Test if device operates within specifications

Initial Filling Test

1. Disconnect the GAS OUT tube from the generator.
2. Turn the blue switch to GAS ON, which will empty the tank. Wait at least 10s until no more gas is flowing out of the GAS OUT connector.
3. Turn the blue switch to GAS OFF.
4. Confirm the pressure gauges shows no pressure inside the tank.
5. Prepare a time-measuring device. e.g. your smartphone.
6. Switch the generator on, start your timer.
7. Initially, the flow display on the left side should show about 1.8 L/min.
8. Once the pressure switch display reaches .645 MPa:
   • Stop the timer.
   • Note down the flow-rate on the flow display.
9. At .650 MPa the generator will stop running.
10. The measured runtime should be between 7 to 9 minutes.
11. The flow rate, measured at 0.645 MPa or shortly before the compressor stops, should be between 1.0 to 1.4 L/min.

Leakage Test

1. Turn the blue switch to GAS OFF.
2. Switch Generator Power ON.
3. Wait about 7 to 9 minutes until the pressure has reached at least .645 MPa (6,5 bar) and the compressor has stopped.
4. Note down the pressures shown on the the pressure gauge and the digital pressure switch.
5. Wait 30 minutes.
6. Again, note down the pressures shown on the the pressure gauge and the digital pressure switch.
7. Compare the values from before and now. No dramatic change should be noticeable. A small difference of 50-100 mBar is expected.

1.4 Maintenance

Every year, open the device and check or perform maintenance on the following:

• Change the Compressor Inlet-Filter.
• Optically check the gas cleaning unit for contaminants. In the unlikely case that pollutants are visible inside the unit, please contact support as the unit needs replacement.
