AWORKING PRINCIPLE
The LARIUS MINI-MIX is a bi-component mixing machine. It
therefore provides for the dosage, mixture and application of
bi-component products.
This machine allows the user to work in low, medium or high
pressure, with both airless or air assisted airless manual or
automatic spray-guns.
The dosing and the mixing of the components are regulated by
an electronic control system.
The hydraulic unit contains two owmeters which regulate the
input of the two components into the mixing lines. It is here,
thanks to a static mixer, that the mixing of the products takes
place.
The machine is made up of 3 main units:
- The intake for the components
- The hydraulic mixing unit
- The command and control unit
ADVANTAGES OF USING THE LARIUS MINI-MIX
- The possibility of using every methodology (low-medium-high
pressure / Air assisted airless / airless painting).
- Increased product savings and consequent waste disposal
savings.
- “Ecological” painting: performed in complete respect for the
working and external environment – Quick drying (even without
a drying oven).
- High quality nish – Less use of paint thinners during cleaning
phases.
- Increased resistance with respect to mono-component paints.
Sectors of use: Generic metalworking, Woodworking and Furnishings,
Aerospace industry, Plastics, Bicycles and motorcycles, Automobile
components, Automobiles, Painting of furniture, chairs, doors, Varnishing,
Emulsion painting.
- The operator must possess and be familiar with the
data sheets of the 2 components (Aand B).
- The operator must be familiar with the characteristics
of both the wash fluid to be used with the catalyser B,
and the wash fluid to be used with the product A.
LARIUS srl SHALL BEAR NO RESPONSIBILITY FOR ANY EVENTUAL DAMAGES DERIVING FROM THE USE OF
WASH FLUIDS INCOMPATIBLE WITH PRODUCTS A AND/OR B.
LARIUS srl SHALL BEAR NO RESPONSIBILITY FOR ACCIDENTS OR MALFUNCTIONS DERIVING FROM LACK
OF FAMILIARITY WITH THE DATA SHEETS AND THE PRODUCTS UTILISED OR RESULTING FROM THE USE OF
PRODUCTS WHICH ARE NOT COMPATIBLE WITH ONE ANOTHER.
ATENTION
- The catalyser and its relative circuit must never be
cleaned with incompatible liquids.
- Make sure that: if the product to be used is water-based,
the relative circuit within the machine is cleaned using
water. If, on the other hand, the product to be used
is solvent-based, the relative circuit must be cleaned
using a solvent.

Make sure that the air line to be connected to the machine is
capable of constantly providing pressure at 7 bar.
Before opening the air line, turn the ball valve (F7) on the general
regulator (F8) to its closed position (horizontal tap).
After having opened the machine's air supply, open the valve
completely and set the regulator to maximum.
WASHING OF THE NEW EQUIPMENT
• The machine has been tested at the manufacturer’s facilities.
Perform a wash cycle with the paint thinner before suctioning
any product.
• Place the suction tubes in the solvent containers or else
pour solvent into the gravity tanks.
• Make sure that all of the taps are closed.
• Circulate the solvent within the output pumps and afterwards
within the entire system.
• Open the machine’s intake taps, as well as those at the
owmeter intake and leave the relative bleeder valves closed.
• Activate an automatic work cycle and circulate the solvent
until it comes out of the machine clean.
• Stop the automatic work cycle and activate a wash cycle.
This cycle will help the user set all of the wash settings so
that that machine will be predisposed to perform future wash
cycles during working phases.
PNEUMATIC CONNECTION
The machine must be connected to the compressed air feeding
system, which is necessary for the pneumatic interlocking.
The connection must be carried out in the following way:

500-700 mm
Check the circuit’s internal pressure by checking the values indi-
cated on the two displays (G3) located above the owmeters (G4).
Make sure that the values are equal, within a certain tolerance
(the tolerance may vary in relation to the working pressure with
which the machine will normally be used).
Wait for the exible spray-gun tube to load (wait for the valves
(G2) to shut off automatically).
Before painting, spray the product into a container (G5) or into
a part of the cab (G6) dedicated to purging, while keeping the
spray-gun at a constant distance from the surface (500-700mm).
Use this same distance for all other applications.
This procedure will allow the user to perform any necessary
adjustments, such as: widening the spray, atomising-air
adjustment, adjustment of the various working pressures, etc.
Once this purging phase has been completed, the operator can
proceed with normal working operations.

The manual cycle keeps most of the interlocking
parts disabled. It is therefore the operator who
must activate or deactivate each single function.
The operator will be responsible for the correct
use the system’s functions in order to avoid
damaging or blocking the lines.
During automatic function, the selection of the
manual cycle will provoke the arrest of all of the
system's functions and the cancellation of the
manual cycle.
The operator can activate manual cycle functionality in the
following manner:
- make sure that nobody is within the working area;
- turn the manual-automatic selector (I1) to the manual position.
Manual controls
Press the F2 button on the operating panel to access the manual
controls screen. Select the eld for the desired valve and set the
value to 1. The valve will open automatically.

The valves are dened as follows:
- Ev A: component A electrovalve
- Ev B: component B electrovalve
These four elds can be used to switch over/open every single
electrovalve while the selector (I1) is set to MAN.
Modify the eld’s value to 0 or 1 in order to activate or deactivate
the relative electrovalve and to allow the selected component to
ow within the machine.
This function is necessary for performing a
complete wash of the entire system when the
two pumps have to be washed using two different
wash fluids (i.e. component A requires water to be
used as a wash fluid and the catalyser B requires
the use of a solvent).
This operation (manual valve opening), must also be carried out
when discharging pressures.
When a valve is opened in the absence of product, the pressure
contained within the mixing block is released.
Carry out the operation for component A and component B (Ev
A, Ev B).
AUTOMATIC MODE
The automatic cycle is used for regular working functionality.
In order to activate automatic mode functionality, the operator
must turn the selector (I1) to the automatic position.
To deactivate automatic mode functionality, just turn the selector
(I1) to the manual position.
When the automatic cycle is active, the program controls the
sequence of the valves for the two components and doses them
based on the requested ratio and based on the “impulse count
frequency” settings.
Access the “General Settings” screen.
The “impulse count frequency" setting affects the frequency of
the valve sequence.
Example:
Let us suppose we are selecting a volume ratio of 3/1 (3 parts A
and 1 part B) and setting a pulse frequency of 1. The programme
will control the valve opening, counting 30 pulses of the A supply
measurer and 10 pulses of the B supply measurer.
If a pulse frequency of 2 were set, the machine would count 60
pulses of A and 20 pulses of B.
The adjustment of the “impulse count frequency”
must be done in such a way so as to avoid high
frequencies which may not be supported by the
components.
TOTAL SHUTDOWN OF THE CONTROL PANEL
The system shutdown procedure requires the main switch (I2)
to be turned to the OFF position.
This operation completely arrests all of the system’s functionalities.

JDESCRIPTION OF THE
PANEL’S FUNCTIONS
The OP73 panel is used by the operator to view and modify
system process variables.
This interface allows the operator to congure some of the
parameters which are necessary for working. This panel also
displays any anomaly messages and/or alarms during the work
cycle.

GENERAL SETTINGS SCREEN (1)
The F1 screen is divided into two parts:
- The rst, for setting the IMPULSE FREQUNCY (impulse multiplication
factor) and the A/B RATIO (the volumetric mixing ratio with which
product A and catalyser B are dosed in order to obtain a proper
mixture);
- The second, where the machine displays the information
regarding the passage of the components through the two
owmeters.
IMPULSE COUNT FREQUENCY:
When setting the IMPULSE FREQUENCY, keep in mind that the
value inserted in inversely proportional to the mixing speed. The
higher the value inserted, the slower the mixing speed.
General settings
Impulse count frequency 000
A/B Ratio 00 /00
This number must be set in accordance with the
viscosity of the materials as well as the pressure
with which the machine is working.
High pressure, low viscosity and a low IMPULSE
FREQUENCY may cause excessive stress to the
equipment and lead to non-homogeneous mixtures.
- In case of high viscosity and low working pressure, use a value
between 10 and 15.
- On the other hand, in case of low viscosity and high working
pressure, use a value around 15 and 20.

POT LIFE
Before initiating any work activities, always make
sure that this field is set properly in relation to
that which is specified in the data sheets of the
products being utilised.
Incorrect settings could lead to the solidification
of the mixed product within the mixing lines.
The pot life is the value which indicates the reaction time (in
minutes) of product A with catalyser B.
Once the set time has passed, the machine displays a message
and a relative alarm indicating that a wash cycle is required.
If the data sheets indicate a value of X as the reaction time, the
machine must be set to a value inferior to X.
In the event of loss of electrical power, the wash cycle
will have to be performed by manually manipulating
the relative electrovalves:
Leave the air intake open.
Since, in this case, the wash cycle cannot be
initiated from the control panel, the valve will
have to be switched manually using a flathead
screwdriver. Alternate valve opening between
the wash fluid and the air, thereby simulating an
automatic wash cycle.
