3.0 Operation
3.1 Switch Functions
Reduces the set pressure
Increases the set pressure
Displays an alternative unit of mesurement
This switch can be programmed to operate in one (1) of the following modes:
Default Unit Mode
Pressing and holding the Switch will momentarily display an alternative unit of
measurement. When you release the switch the display will immediately revert back
to the default unit of measurement.
The pressure can only be set in the default unit of measurement.
Selectable Unit Mode
Pressing and releasung the Switch will display an alternative unit of measurement.
the pressure ca be set in any of the units of measurement.
The units displayed on each machine will vary depending on the software that has
been requested.
The ‚Flat Tyre Only‘ Switch dischanges up to five (5) bursts of air. udes when
the pressure in the tyre is less than 3psi, 20kPa or 0,2 bar.

3.2 Inflation & Deflation
3.2.1 Set the desired pressure, refer to Section 3.1 for the function oft each Switch
3.2.2 Connect the hose to the tyre, ensure the hose is connected securely. Air leaks
will cause an error message to be displayed, refer to Section 4.0.
3.2.3 The Pressure in the tyre will be displayed.
3.2.4 The unit will inflate or defalte the tyre to the set pressure. Periodically the
process will stop and display the pressure in the tyre.
3.2.5 If the pressure in the tyre is less than 3psi, 20kPa or 0,2bar the process will not
commence until the ‚Flat Tyre Only‘ Switch is pressed, refer Section 3.1.
3.2.6 The scroll bar will indicate that the unit is inflating or deflating, see below
3.2.7 When the set pressure is reached the display will flash and the unit will beep
five (5) times. This will continue until the hose is disconnected, during this time
the keypad will be disabled.
3.3 Volume Adjustment
3.3.1 Turn off the unit
3.3.2 Press and hold the Decrease and ‚Flat Tyre Only‘ switches, refer to Section 3.1.
3.3.3 Turn the unit on, VOL will be displayed.
3.3.4 Adjust the volume using the Increase and Decrease switches, refer to Section
3.1.
3.3.5 To store the settings press the ‚Flat Tyre Only‘ switch. Further changes can be
made by repeating the above procedure.

8.0 Compressed Air Systems
The information in this section is designed to provide some basic information about
compressed air systems and the use of digital inflation equipement.
Compressed air systems contain oil and water, it is important to filter and drain these
from the system.
The water is generated by condensation and oil can be carried into the line from the
compressor. A basic system is illustrated below. The components of this system are
as follows:
1. Air compressor
2. Air reciever tank
3. Valves
4. Filter & Regulator
5. Condensate drain (Water Tap)
6. Digital tyre inflator
Each system and installation of digital inflation equipement is different however it is imperative
with any system that the drain valves (No.3) are opened routinely to remove water that has been
collected.
Immediately prior to the tyre inflator (No.6) a regulator (No.4) should be fitted. This should be set
to 10psi, 70kPa or 0,7bar above the maximum set pressure of the unit. this will prevent excessive
pressure being supplied to the unit and the resulting error message Er4. Refer to section 4.0
Troubleshooting.
Also prior to the tyre inflator a filter (No.4) should be fitted. This filter should remove all solid
materials such as scale caused by corrosion inside the pipe and reservoir. Contaminants may
have an adverse effect on theinternal components of the
system due to blockage an corrosion.
