4 1 Product description The foam marker transforms a mixture of foaming agents, added to clean water, into a foam that can be seen on the ground. The foam, which is inert, visually marks out previously treated areas of crop, thus avoiding double treatments, product wastage and potential damage to the crop. 1.1 Intended use Device designed for installation to crop-spraying, spraying agricultural machinery and forestry machinery. This equipment has been designed and manufactured in compliance with the following directives and standards: 2004/108/CE and subs. mod. (Electromagnetic Compatibility); 97/23/CE and subs. mod. (Pressure equipment); 98/37/CE and subs. mod. (Machinery); EN ISO (Agricultural and forestry machinery - Electromagnetic Compatibility - Test methods and acceptance criteria). 2 precautions Foaming agents in general are potentially toxic! Only use the foam marker outdoor or in well ventilated environments wearing the required individual protection gears, overall, gloves and mask. Never expose the equipment to water jets. Never use solvents or petrol to clean the external parts of the container. Do not use direct jets of water for cleaning the device. Comply with the specific power supply voltage (12 Vdc). In case of electric arc welding, make sure that the power supply to the device is disconnected; if necessary, disconnect the power supply cables.

On seeders, install the electric-compressor unit sheltered from areas that are too dusty. Install the foam marker at bar ends using the supplied supports at a distance from the last spraying nozzle equal to half the distance of one nozzle to the other (Fig. 3). The foam must fall in an area sheltered from the nozzle and the point where it falls must mark the area treated by the boom. Fix the pipes of the pneumo-hydraulic system to the framework with clamps, in a position protected from possible impact with the ground or with the boom framework. At the joints of the booms the pipes must be of such a length as to allow the booms to open and close without damaging the pipes. Place the tank upright with the cap easily accessible for filling and adjusting the flow rate. Apply the tank so as to make it possible to be removed for periodical washing. The compressor cover should be easily removed for maintenance operations. Fig. 3 5

9 5.7 Installing the control box Fig. 9 Install the control box into the driver s cabin: position the fastening slide with the screws (Fig. 9) where the driver can easily see and reach the box provided that it is far from any moving parts; secure the control box to the slide by inserting and pushing it down until it locks in place. Fix the wirings so that they do not come into contact with moving parts. Connect the supply cable to the starter key 15/54. If the contact 15/54 (auxiliary) of the starter key can withstand a continuous load of 10A, make the connections of Fig. 10 section A. Otherwise, insert a relay as shown in Fig. 10 section B. Minimum cable cross-section: 2,5 mm². CAUTION: so as not to run the risk of short-circuiting, do not connect the supply cable connector until installation has been completed. Fix the electric cables, making sure that the connections are mounted in a protected position. Fig. 10 Connect the control box to the compressor unit using the supplied cable. 5.8 Accessory connections: positioning the foam marker control kit To use the foam marker with a BRAVO computer install the foam marker kit as described in the instructions supplied with the very kit (please refer to ARAG General Catalogue for part numbers). 5.9 Final testing 1) Insert some litres of water into the tank. 2) Screw the cap onto the tank fully. 3) Move the selector (A, Fig. 12) to the right and start the compressor unit. 4) Ensure that fluid comes out from the right foam marker after some seconds. 5) Check the correct seal of the hydraulic couplings. 6) Shift the selector to the left (A, Fig. 12) and start the compressor unit. 7) Ensure that foam is coming out from the left maker. 8) Check that no hydraulic connections are leaking. 9) Interrupt delivery by setting the switch to its central position (OFF). 10) Depressurize the tank as indicated in par Discharging remaining pressure. 11) Empty the water from the tank. 12) Clean the circuit as described in chap. 7 - Maintenance / diagnostics / repairs. 9

10 6 UsE 6.1 Discharging remaining pressure Fully depressurize the system as described below before removing the tank plug: Fig. 11 Cut off the supply to the foam marker. Pull the red pin of the relief valve onto the tank plug and then discharge any residue pressure as shown in the figure. 6.2 Control devices A Lever control switch for foam delivery (Left / Off / Right). B Pilot lights checking and controlling the treated portion. Fig Preliminary checks After a long period of disuse and before every new use, check the tightness of the fittings. 6.4 Preparing foaming solution Pour an amount of concentrated foaming liquid into the tank according to the instructions given on the package of the product (see par. 6.6). Add clean water to fill the tank, using a pipe inserted down to the bottom of the tank so as to mix the product well and prevent foam from forming. Screw on the cap and tighten it carefully. For use during the winter, add automotive antifreeze in the amount specified on the antifreeze package. 10

11 6.5 Starting and operating Operate the selector lever (A, Fig. 12) onto the control box and start the compressor. The indicator turns on and the circuit reaches the operating pressure after a few seconds causing the foam to come out from the selected foam maker. Adjust the intensity of the foam outlet, using the flow-rate regulator on the tank cap (Fig. 13). During use it is possible to alternate the right- or left-hand foam nozzle by moving the selector lever. To interrupt foam marker operation, set the switch to its central position (OFF). Fig Topping up liquid Depressurize the tank as indicated in par Discharging remaining pressure. Refill with liquid, observing the procedures described in the par Preparing foaming solution. Use only ARAG foaming agents.

12 7 Maintenance / diagnostics / repairs 7.1 Max. pressure valve Max. pressure valve onto the tank plug is maintenance free. The action of the pressure discharge pin onto the tank plug avoids any clogging of the relief valve and - at the same time - ensures its proper operation. 7.2 Machine down for up to 7 days For periods of disuse up to 7 days, proceed as follows: Horizontal foam markers Vertical foam markers Fig. 14a Fig. 14b Fully depressurize the tank as shown in Par. 6.1 Slacken the band (B) and remove the diffusor (A). Only for horizontal foam markers (Fig. 14a): completely slacken the bands and remove the diffuser in the arrow s direction. Wash the diffuser (A) with water. Remove the grid (C) turning it anticlockwise. Extract the sponge (D) from the generator (E). Carefully wash the foam diffusers and sponge with water. Reassemble the parts taking care when inserting the sponge that must go into its seat freelyand without compression, as this may compromise foam marker operation. Repeat the above operations for the other foam marker as well. 12

13 7.3 Machine down for up to 30 days For periods of disuse up to 30 days, proceed as follows: Depressurize the tank as indicated in par Discharging remaining pressure. Slacken and remove the cap (C). Remove tank (A) and wash with clean water. Wash the bottom filter (D) with clean water. Fit the tank into the retaining basket. Add a few litres of water into the tank, put the cap back on. Restore the electrical connections. Wash the hydraulic circuit, operating alternately the lever selector in the position corresponding to the boom section involved until clean water comes out of the diffusers. Fig. 15 Depressurize the tank as indicated in par Discharging remaining pressure. Unscrew and remove the cap and immediately empty the tank of any remaining water. Remove the water/air hoses from the cap and connect them to each other with the provided snap fitting as shown in Fig. 16. Empty the hydraulic circuit by operating the lever selector in the position corresponding to the boom section involved until only air comes out of the diffusors. Fig. 16 Fit all the parts back together to restore the initial conditions. Clean the diffusers as described in par Machine down for up to 7 days. 7.4 Machine down for longer than 30 days For long periods of inactivity, proceed as follows: Run the operations described in par Machine down for up to 30 days. Clean the compressor unit: - Remove the cover by taking out the screws (A). - Clean the inside with compressed air (wearing a face-mask and safety goggles). - Spray the self-cleaning liquid for electrical contacts through the slots on the electric motor. - Reinstall the cover. Fig

14 7.5 Reactive maintenance To ensure dense and lasting formation of foam, replace the sponges code (D, Fig. 14a +14b) every year. 7.6 Pipe repairs Fig. 18 If the hoses break, repair them with one of the snap fittings (code or ) provided with the package. Proceed as follows: Use a pair of scissors to trim the broken ends of the hose. Fit the two ends into the fitting. 7.7 Fuse replacement Before replacing the fuse, disconnect the control box from the battery. Lift the fuse holder cap (A) onto the power cable. Replace the old fuse (B) with a new one of the same type (10 A): the package includes a spare fuse. Recap and check for proper cap position. Fig

15 7.8 Troubleshooting DEFECT CAUSE REMEDY The compressor unit does not work, the warning lights do not turn on No foam coming out from the foam marker Foam formation is not good Bleed air from the max. pressure valve onto the plug Air or liquid leaks from the fittings The compressor unit does not work, the warning lights flash only once No power to the control box Electric connection between control box and compressor cut off The tank will not pressurize Break in the pneumo/hydraulic circuit Sponge dirty or hardened Water-foaming agent mix old Flow-rate adjustment wrong Constrictions in pipes Constrictions in the pipes Incorrect fitting seal Check the fuse. Check the electrical connections of the control box. Check the connections between the control box and the electric compressor. Close the tank cap properly. Check the tightness of the pipes connecting the compressor with the cap. Check there are no cracks in the darkblue pipe inside the tank (from the filter to the plug) and on the outer pipes. Clean the bottom filter of liquid. Check for any constrictions along the pipes. Clean or replace the sponge in the generator. Redo the water-foaming agent mix. Use the flow-rate regulator on the tank cap to obtain a sufficiently dense foam. Check the tubes to the foam markers. Check the tubes to the foam markers. Detach the hose at the snap or threaded fittings and shorten it by around 10 mm to eliminate deformations at the fitting. +/- power reversed Repair the electric connection. 15

16 7.9 Problems due to the solenoid valves locking up In case of air or fluid leakages from the connector or if the foam comes out from a non-selected foam generator, solenoid valves (Fig. 21) might be stuck. Before doing anything else, disconnect the control box from the battery. Free up the solenoid valves as follows: Disconnect the tubes from the compressor unit to the foam generators. Blow with compressed air into the unions of the solenoid valves towards the compressor (Fig. 20). If the problem persists, contact your local service centre. Fig. 20 For not specified problems, contact your dealer or the ARAG service centre. 8 Technical data Description Value Power supply voltage Vdc Current draw (at 12 Vdc) 9 A Working temperature 0 C +40 C / +32 F +104 F Tank capacity 27 l Working pressure (at 12 Vdc) 0,75 bar Max. pressure valve setting 1 bar Water/foam agent solution consumption* 35 l/h max Total weight excluding packing 17,5 kg Noise level 70 db (A) * Using foaming agent ARAG at the concentration given on the package, (see par ) 9 End of life disposal To be disposed in compliance with the legislation in force in the country in question. 16
