ACJ Series Applicator Systems 1 ACJ Series Applicator Systems 1. Safety Read and follow these safety instructions. Task- and equipment-specific warnings, cautions, and instructions are included in equipment documentation where appropriate. Make sure all equipment documentation, including these instructions, is accessible to persons operating or servicing equipment.
2 ACJ Series Applicator Systems Personal Safety To prevent injury follow these instructions. Do not operate or service equipment unless you are qualified. Do not operate equipment unless safety guards, doors, or covers are intact and automatic interlocks are operating properly. Do not bypass or disarm any safety devices. Keep clear of moving equipment. Before adjusting or servicing moving equipment, shut off the power supply and wait until the equipment comes to a complete stop.
ACJ Series Applicator Systems 3 High-Pressure Fluids High-pressure fluids, unless they are safely contained, are extremely hazardous. Always relieve fluid pressure before adjusting or servicing high pressure equipment. A jet of high-pressure fluid can cut like a knife and cause serious bodily injury, amputation, or death. Fluids penetrating the skin can also cause toxic poisoning. If you suffer a fluid injection injury, seek medical care immediately.
4 ACJ Series Applicator Systems Fire Safety To avoid a fire or explosion, follow these instructions. Ground all conductive equipment in the spray area. Use only grounded air and fluid hoses. Check equipment and workpiece grounding devices regularly. Resistance to ground must not exceed one megohm. Shut down all equipment immediately if you notice static sparking or arcing. Do not restart the equipment until the cause has been identified and corrected.
ACJ Series Applicator Systems 5 Halogenated Hydrocarbon Solvent Hazards Do not use halogenated hydrocarbon solvents in a pressurized system that contains aluminum components. Under pressure, these solvents can react with aluminum and explode, causing injury, death, or property damage.
6 ACJ Series Applicator Systems 2. Description The ACJ Series applicator systems are typically used in Nordson Century workcells to dispense solder flux on printed circuit boards and other electronic components. This section describes the system components and their functions, and the different applicator versions and options. System Components and Functions Figure 1 shows a typical ACJ system with options.
ACJ Series Applicator Systems Applicators 7 See Figure 2. Two applicator versions are available. 1 2 3 4 4 5 6 7 ACJ-S ACJ-ST 1246002A Fig. 2 ACJ-S and ACJ-ST Applicators 1. 2. 3. 4. Micrometer Solenoid Body Air inlet fitting 5. Bracket 6. Syringe 7. Fluid inlet fitting ACJ-S Applicators ACJ-S applicators have an integral reservoir (syringe) that holds the flux supply. The syringe is completely sealed and pressurized to ensure a steady flow of material.
8 ACJ Series Applicator Systems ACJ-ST Applicators ACJ-ST applicators are supplied with flux from an external, pressurized reservoir. ACJ-ST applicators are available in the following versions: without heater with heater See Figure 3. The controller is typically mounted in the cabinet under the workcell coating area. It operates on 120 Vac and outputs 24 Vdc to energize the applicator solenoid for a selected time period.
9 ACJ Series Applicator Systems Fluid Pressure Controller See Figure 4. The fluid pressure controller is typically mounted in the workcell coating area. Maximum input air pressure is 7 bar (100 psi). 1 FLUID PRESSURE 3 2 OFF ON 4 1246004A Fig. 4 Pressure Controller 1. Digital pressure display 2. Pressure regulator Options 3. Air supply indicator 4.
10 ACJ Series Applicator Systems Optional Co-Axial Air Nozzles Co-axial air nozzles are installed on the applicator directly on the fluid nozzle. Air flowing from the nozzle helps the dispensed flux spread out on the substrate, providing even coverage. Four sizes of air nozzles are available: narrow face, .030-in. orifice medium face, .030-in. orifice wide face, .030-in. orifice medium face, .050-in.
ACJ Series Applicator Systems 11 WARNING: Allow only qualified personnel to perform the following tasks. Follow the safety instructions in this document and all other related documentation. 3. Operation Refer to your Century workcell manual for system setup and operating procedures. Startup 1. See Figure 4. Turn the pressure controller valve to the OFF position. 2. Fill the ACJ-S syringe or ACJ-ST reservoir: ACJ-S Applicators: a. Remove the thumbscrew from the applicator bracket. b.
12 ACJ Series Applicator Systems Startup (contd) 5. See Figure 4. Turn the pressure controller valve to the ON position and set the fluid pressure as desired. 6. If using a co-axial air nozzle, set the desired air pressure. The co-axial air pressure regulator and gauge are typically installed on the workcell front panel. 7. Place a test sheet under the applicator nozzle and run a dispense program. Check the results and adjust the dispense parameters as desired.
ACJ Series Applicator Systems Short-Term Shutdown 13 1. Shut off the ACJ-1 power switch. 2. Turn the pressure controller valve to the OFF position. Long-Term Shutdown If the flux will deteriorate during a long-term shutdown perform the following procedures: 1. If you are using an ACJ-ST applicator, empty the reservoir and fill it with a compatible solvent. Run a purge program and flush the system. 2. Shut off the ACJ-1 controller power switch. 3. Turn the pressure controller valve to the OFF position.
14 ACJ Series Applicator Systems WARNING: Allow only qualified personnel to perform the following tasks. Follow the safety instructions in this document and all other related documentation. 4. Troubleshooting This section contains troubleshooting procedures that cover the most common problems you may encounter. If you cannot solve the problems with the information given here, contact your local Nordson representative for help. Troubleshooting Chart Problem 1. 2. 3.
