5 Automatic spray gun A15 eco ENGLISH 1 Function and identification 1.1 Function Automatic spray guns are used for the automatic coating/marking of surfaces Dosing of fluids Placement of adhesive or marking points Typical spray fluids are paints, dyes, adhesives, debonding agents, etc. The spray fluid is fed into the automatic spray gun under pressure. This pressure is typically generated by pumps or pressure containers. The automatic spray gun is controlled via compressed air. Upon opening, the control piston charged with compressed air initially opens the air nozzle and then with a short delay the fluid nozzle of the spray gun. Upon closing, initially the fluid nozzle and then the air nozzle is closed in order to prevent a subsequent dripping of the spray fluid. For the precise control of the automatic spray gun, electrically-activated solenoid valves can be used, for example. Switching times of 60 ms can be achieved this way. The spray fluid is atomised using compressed air. The geometry of the spray jet and the sprayed quantity of the spray fluid can be adjusted with the following measures: Selection of the air and fluid nozzle Changing of the atomiser air pressure Changing of the spray fluid pressure Adjustment of the needle stroke on the regulator of the automatic spray gun. The automatic spray gun also features the following additional characteristics: Head section only in aluminium, hard-coated Main element with flat jet regulator or with flat and round jet control 1.2 Identification Scope of delivery Model Product number Aluminium head section; fluid connection on the bottom Operating instructions T-Dok-665 Serial number The serial number of the automatic spray gun is located on the main element.

23 Automatic spray gun A15 eco ENGLISH 6.3 Operation To achieve optimal results, adhere to the following: Rinse the automatic spray gun with cleaning products before commissioning. Too-high air pressure causes unnecessarily high air consumption and too-strong atomisation of the spray fluid. The diameter of the hose for the supply of atomiser air must be 8/10. Too-low air pressure produces an unsatisfactory spray pattern. Select the lowest possible fluid pressure. 1. Make sure that the control air and atomiser air connections are not reversed. 2. Close the control air (connection "St"). 3. "Open" material supply. Depending on the type of material supply, the "opening" of the material supply is carried out By opening the connection tap By applying pressure to the storage container By filling the material into a storage container (hydrostatic inherent pressure). 4. Open the control air. ð The fluid is sprayed. Generally, the adjustment of the spray pattern is now required ( Ä Chapter 6.4 Adjusting the spray pattern on page 23). 6.4 Adjusting the spray pattern Air and fluid nozzles are available in various sizes. There are 4 different families: Round jet cone-shaped jet in front of the nozzle. Flat jet width-adjustable jet for flat-shaped application. Depending on the design, flat jet nozzles can be adjusted to adapt steplessly to the work piece geometry or in 45 increments. Adjust the spray pattern with the following measures: Change the atomiser air pressure. Change the pressure of the spray fluid. Select another nozzle size. Adjust the needle stroke (optional) ( Ä Chapter 6.5 Setting the zero point of the needle stroke setting on page 26) GB 23

24 Operating instructions T-Dok-665-GB-Rev. 0 Excessive air pressure causes unnecessarily high air consumption and excessive atomisation of the spray fluid. It is recommended that you first adjust the spray pattern by varying the air and spray fluid pressure. If you cannot achieve satisfactory results this way, you should experiment with other nozzle sizes. To reduce overspray and the concentration of harmful substances when coating, observe the following points: Guide the spray jet vertically to the surface Adjust the spray jet to suit the geometry of the work piece The spray gun should be as close to the work piece as possible Always spray in the extraction direction GB 24 mail@krautzberger.com,
