vice. The troubleshooting actions can be performed based on error codes displayed or symptoms displayed by
the NTI 105.
5.1 Based on error codes
Error code Messages Actions
01 HOSE IMPROPER
R
Disconnect the filling nozzle from the tire and connect it back to tire. Ensure
that the hose is connected to the digital outlet port.
R
Check if there is leakage at the connector. If there is leakage, the clip should
be tightened.
02 SET PRESSURE EXCEEDS Check the set pressure value. It should be equal to or lesser than 65 psi.
03 POWER SUPPLY ERROR Contact customer service.
04 PRESSURE SENSOR ERROR Contact customer service.
06 Pressure Plausibility
R
Check tire pressure and ensure that it is within recommended range.
R
Refer and execute actions described for error 1.
R
Ensure sufficient tank pressure/inlet pressure during filling.
R
Pressure sensor may not be functioning. Contact customer service.
5.2 Based on symptoms
Symptom Indication Actions
Nitrogen pressure gauge displays
0 psi
No nitrogen in the nitrogen tank because of any
of the following reasons:
R
Leakage at the CMS tank outlet.
R
Failure of non-return valve.
R
Bursting of the pneumatic pipe at the output
of CMS tank.
R
End fittings of the nitrogen tank are loose.
R Safety valve is loosely connected.
R Burst or leakage in the pneumatic pipe at the
output of nitrogen tank.
R Leakage at the end fitting of pressure gauge.
R
Contact customer service to replace
the pneumatic pipe of the CMS tank.
R

Filling rate of nitrogen is slow
R
Pressure of the compressed air supply to the
unit is less than 8 bar.
R Pressure of the compressed air supply is not
continuous.
R Flow rate of the incoming compressed air is
less than 120 lpm.
R
For best performance, ensure that the
pressure of compressed air supply is
constantly in the range of 10 bar to 16
bar. Also, ensure that the flow rate is
120 lpm.
