3. Plug in the Auto Tire Fill System
4. Turn both valves on NTF unit to “FILL TIRE”
5. Connect hoses to tires
6. Set the final target pressure by pressing + or - buttons
7. To change Over Pressure and Nitrogen Purge Cycles
Settings, see sections below
8. Move “Red” slider valve to up position
9. Press N2 button once for Standard Inflation,
or
hold
N2 button to invoke Nitrogen Purge Cycle
- Standard Inflation will inflate or deflate to the
target pressure
- One complete Nitrogen Purge Cycle is the
process in which the Auto Tire Fill System will
deflate to 3 PSI, Inflate to target pressure, deflate
to 50% of target pressure, then inflate to final target
pressure (If 2 or more Nitrogen Purge Cycles are
programmed, the above process will be repeated)
10. When unit beeps 5 consecutive times, slide “Red”
valve to down position
11. Wait 10 seconds before disconnecting hoses

Unstable pressure
Verify that air chuck is pressed
all the way onto the tire
ER2
Unstable pressure,
incorrect supply pressure,
or Inflate/deflate valve
connections are reversed
Verify that air chuck is pressed
all the way onto the tire. Check
valve connections on PCB.
ER3
Low or no supply pressure
Verify that air chuck is pressed
all the way onto the tire
ER4
Initial or final pressure is
too high, exceeds
maximum pressure by
more than 20 psi, 140
kPa, or 1.4 bar
Turn bottom valve on NTF unit
to vacuum tire. Turn off power
for a minimum of 5 seconds. If
error reappears, call RTI
ER5
Low supply voltage
Check power supply, message
will clear when correct voltage
is restored

Program or PCB error
Turn off power for a minimum of
5 seconds. If error reappears,
call RTI
ER8
Calibration error
Calibration required, call RTI
ER9
Calibration error
Turn off power for a minimum of
