2


c) Installation.

1- Drill the wall using the Pneutronic´s back plate.

2- Replace the PNEUTRONIC in the support using
the four screws that were previously released.

3- Before placing the incoming hose, let the air flow
for some seconds so as to remove all dirt and
humidity.

4- Install the incoming and out flowing hoses. Both
hoses are attached by using two clamps.

5- THE INCOMING PRESSURE OF THE
EQUIPMENT SHOULD NOT EXCEED 175 PSI
(12 Bar). IF NECESSARY, USE A PRESSURE
REGULATOR.

6- Plug Pneutronic to power supply. Make sure the
power supply is compatible.

d) Functioning.

1- Choose the desired pressure value using the buttons and ;

2- Connect the nozzle to the tire ;

3- Wait for the “beep” ;

4- Push button for flat tire;

5- Remove the nozzle from the tire that has been calibrated and repeat the
process with any other tires to be calibrated. If you wish to calibrate the same
pressure value in every case, it is needed to connect the nozzle to the tire and
wait for the beep when the process is ended.

3


e) Maintenance.
To ensure perfect performance of PNEUTRONIC, as well as its life span it is
necessary to adopt some measures.

1 - Never allow the incoming pressure of the equipment to exceed 175 PSI (12 Bar).

2 - The nozzle of PNEUTRONIC must be changed every time those losses are
recorded.

NEVER PLACE A NOZZLE “CLOSE-END” IN THE PNEUTRONIC BECAUSE SUCH
A NOZZLE PREVENTS THE EQUIPMENT FROM FUNCTIONING.

3 - It is necessary to keep the air line free from dirt so as to avoid the clogging of the
filter.

4 - It is necessary to perform a regular cleaning of the front panel of the PNEUTRONIC
using soap and water.

f) Troubleshooting.
If the PNEUTRONIC does not reach the desired pressure, and gives a higher or a
lower value instead - it is necessary to verify if there is any leak in the hose, in the
connections or in the nozzle;

If the calibration takes a long time - it is necessary to clean the air line or the filter
of the PNEUTRONIC;

If the PNEUTRONIC does not perform the calibration - it is necessary to replace
the nozzle of the hose just in case it is improperly connected, or to change it if it has
any problem, or to push the “FLAT TIRE” button, if the tire is empty;

If the beep sounds when there is no tire connected to the hose - it is necessary to
verify if the nozzle of the hose is not clogged or change it for an “open-end” one;

If it seems that PNEUTRONIC is functioning by itself - without stopping, please
verify if the nozzle of the hose is not clogged or to change it with an “open-end” one;

In case of doubt, or if your PNEUTRONIC needs to be repaired, please get in touch
with the Technical Assistance Department of your Dealer.

4


g) Accessories.
The accessories of the PNEUTRONIC that are available are the following:

• European hose nozzle open-end;
• Pedestal to be used when the equipment can not be affixed to a wall; incorporates a
metallic hood to protect the equipment from the effects of the weather.

11. Basic characteristics of Pneutronic Software

When the equipment is turned on, the default pressure configured (for example,
“26” PSI) is shown.

The keys “+” and “-“ are used to increase or decrease the value of the pressure
shown on the display (chosen value). As the value on the display is increased or
decreased a “beep” sound is heard. It can be noticed that the values shown on the
display change more quickly (to make the selection quicker) after the value has
been increased or decreased three consecutive times.

When the “FLAT TIRE” key is pressed alone it starts the calibration process in a
flat tire. CHARGE is activated eight times, with a short interval at each time. The
equipment reads the amount of pressure each time the CHARGE is activated and if
it detects a pressure that is higher than the minimum (“0,2” Bar) it will shift to an
automatic calibration process.

This “FLAT TIRE” process can be aborted by pressing again the “FLAT TIRE” key,
only before it starts the automatic calibration process.

When the “i” key and the “-“ key are pressed in sequence the message “Cnt” shall
appear for a moment on the display followed by a number between 0 and 1999
indicating the number of calibrations performed by the equipment.

When the conversion key (“i”) is pressed the message “PSI” (or “BAR”, unit to be
converted ) appears for a moment on the display, and then it shows the converted
value.

19. Procedure to Test Precision

Objective: Testing the pressure measured by Pneutronic against a master meter on
different temperatures and pressures.

Procedure:
0 - Go through calibration procedure.
0.1 - Close the equipment to its normal use (with the cover in the back).
1 - Turn on the equipment and wait for 10 minutes for temperature stabilization.
2 - Turn it off and turn it on again, and enter in the test mode.
3 - Test different pressures
4 - The temperature can be changed to another value. Wait for thermal stabilization
before further tests.
5 - Test different pressures.

34


20. ERROR MESSAGES TABLE

Er1 – Board Problems, contact Distributor/Factory for technical support. Not user
serviceable.

Er2 – Valve Problems, check the diaphragm of the valve.

Er3 – Verify that the incoming pressure (compressor) is below the level necessary to
obtain the desired calibration. It is also necessary to verify if the air tap is closed.

Er4 – Calibrate and make the basic parameterization of the equipment.

Er7/Chuck - It is necessary to verify if the nozzle of the hose is not clogged or to
change it for an “open-end” one; It also appears if the nozzle keeps connected to the
tire more than 15 seconds.
