What are the reasons why the nitrogen machine can't start

1, the nitrogen generator power supply is not turned on, check the power supply, turn on the power supply;

2, nitrogen machine drive air source pressure reducing valve is not open or open too small, check the drive air source, adjust to the required range (0.4 ~ 0.6MPa);

3, the front stage without compressed air, to ensure the normal supply of compressed air;

4, the amount of compressed air is insufficient, the adsorption pressure of the nitrogen machine is too low;

5, nitrogen generator magnetic valve failure.
