The product
The Cyclomix
®
Evo allows the selection of all connected products.
It is therefore possible to choose a product connected to the A, B or C color changer, whether this product is a solvent,
a color or a catalyst.
Volume or time
It is possible to choose a volume of product to be circulated or to define a time during which the product valve will
remain open.
When the product passes through the flow meter, it is best to select a volume. This allows the Cyclomix
®
Evo to
control that the correct volume of product has passed.
When a time is selected, even if the gun is closed, the time will run out when no solvent has been circulated. There is
therefore a risk that the flushing will not be done properly.
2.5.7.2. AIRCHOP strategy
The AIRCHOP strategy corresponds to a cycle where solvent and air
are sent in succession. This mixture of air and solvent provides a
mechanical action that improves the flushing cycle while consuming a
minimum of solvent.
The different parameters to be filled in to define an AIRCHOP step are:
• The circuit to be cleaned. Refer to the appropriate section..
• The product to be used. See the appropriate section.
• The fluid valve opening time.
• Air injection time.
• The number of solvent/air cycles to be performed.
• The time delay between the solvent valve closing and the air valve opening.
• The equipment where the product must be evacuated..
Knowing that the mixture of air and solvent will create disturbances in the circuits, all the cycles are defined by a time.
It is therefore not possible to measure the volume of solvent used during this flushing stage..
The tempo field is useful mainly when the product pressure is higher than the air pressure. The air pressure is usually
set around 6 bar.
When the product pressure is higher than 6 bar, it is then necessary to have a time delay in order to allow the
pressure in the circuit to go down below 6 bar and thus allow the injection of air in the circuit.
2.5.7.3. Temporization strategy
Contrary to the "Airchop" strategy which allows to bring a mechanical action to the flushing cycle, the
"Temporization" strategy will allow to have a chemical action by leaving the circuit closed during the defined time.
This strategy must always be positioned after a "Product" strategy where solvent has been introduced into the
circuit. This delay will allow the solvent to dilute the paint and thus facilitate the cleaning of the hoses wall.
During this delay phase, it is necessary to leave the gun closed. When the Cyclomix
®
Evo is equipped with a flushing
box, it will not be controlled during this waiting phase.
2.5.7.4. First stage of flushing
If the paint optimization function has been activated in the configuration menu, then the first step will necessarily be
defined with a product strategy and it will only be possible to select a solvent.
