The CFV1 board is to be installed in the electric cabinet of the spray booth and carries out alla the control operations.

At hardware level, the board is equipped with outputs designed to control:

• Single stage, 2 stage, sliding or modulating burners

• "Belimo" air shutter

• Inverter or "soft-start" operated fans

• Air cylinder-operated valves

• Solenoid valves

• Lighting of the interior of the booth

Also, the inputs can handle:

• Temperature of booth and output conduits

• Pressure of booth and filters

• Air humidity

• Alarms from inverter and burner

• Fire dampers

CFV1's software allows it to be configured for many different types and setups of booths.

The working process is organized and memorized in programs that the user can easily create and edit. A temperature and a duration in minutes can be set for every step of the job and the system automatically proceeds to the next one without needing any intervention on the operator's behalf after the painting has been done.

The typical program is composed of: painting, passivation, drying and cooling but the operator can also insert steps such as pre-flashing, pre-drying and "smart-cure".

The CFV1 board checks the temperature of the booth using different algorithms suited to the type of burner installed. In additon to the well-known PID control, smart-following systems have been implemented to increase greater accuracy and smaller heat shocks in booths with high thermal inertia.

The control of the pressure inside the booth is a very important functionality. The internal pressure is kept at -5mBar (but the user can set a different one) to avoid the leak of fumes or dust during the painting. CFV1 is also able to detect the clogging of any of the filters and sounds an alarm when it has to be replaced. This means increased safety and always working in optimal conditions for both the operator and the booth.

CFV1 can also monitor the consumptions, memorize how much fuel and electricity have been used during each working step and file the data grouping them by day, month or year. An optional Bluetooth interface can be added to connect CFV1 to a computer equipped with a specialized software that allows the user to download the data relative to consumptions and cost of each working step and also to set every parameter of the system.
