E 1995 Nordson Corporation

18 1-4 afety 5. Installation and Electrical Connections Prior to installation, check intended location and surrounding area for any potential hazards during operation. All electrical, pneumatic, gas and hydraulic connections and installation of all system components may only be carried out by qualified personnel. Observe installation instructions for components and accessories. Equipment must be properly grounded and fused according to the rated current consumption (see ID plate). Cables which run outside the system must regularly be checked for wear or damage. Power supply wire gauge and insulation must be sufficient to handle rated current consumption. Cables must never be squeezed or pinched. Do not locate cables or hoses in high traffic areas. Check liquid adhesive feed hoses, screwed connections and compressed air lines regularly for leaks. These are to be replaced at the first signs of cracks, brittleness etc. Release system pressure completely beforehand. WARNING: Failure to install the system properly, and especially failure to ensure electrical, pressurized and high pressure feed connections are made correctly may result in serious injury or death. 6. Operation The system should only be operated when it is in working order. It should only by operated by qualified persons following all regulations valid for liquid adhesive systems. Never allow the system to be operated by personnel under the influence of substances which reduce their reaction times, or who are not able to operate the equipment for physical reasons. Prior to each startup of the system, check protection and warning devices and make sure they are fully functional. Do not operate the equipment if these devices are not functioning properly. When the removal of safety equipment is required for installation, maintenance or repair, it must be reconnected immediately upon completion of the work. In a humid environment, only equipment featuring a corresponding class of protection may be operated. Do not operate the system in an explosive environment. E 1995 Nordson Corporation

19 afety Operation (contd.) Keep parts of the body and clothing away from rotating parts. Do not wear loose articles of clothing when operating or servicing equipment with rotating parts. Remove wrist watches, rings, necklaces or similar jewelry and pin up or cover long hair before performing any work on or with the equipment. The wearing of protective gloves may prove hazardous in certain circumstances where rotating parts are present and may therefore be forbidden. To carry out measurements on the substrate or system components, switch off parent machine and/or system and wait until the equipment comes to a standstill. Never point guns or applicator nozzles at yourself or other persons. Less- obvious Dangers WARNING: An operator or service technician working with the equipment should be aware of the less--obvious dangers that often cannot be completely minimized at production sites: Pressurized system components The possibility that electrical potentials may remain in the system after the system was de--energized Liquid adhesive vapors Hydraulically or pneumatically operated system components Uncovered winding parts Action in the Event of ystem Malfunction If the system malfunctions, switch it off immediately. Turn the main switch off, or use emergency stop switch or similar safety feature as provided. After equipment has come to a standstill and before reoperating it, have it repaired by qualified personnel. E 1995 Nordson Corporation

20 1-6 afety 7. Maintenance / Repair Allow only qualified personnel to perform the procedures described in this document. Work should only be carried out on a completely depressurized system, following all safety procedures. NOTE: Depending on the configuration of the liquid adhesive application system, high pressure may remain between application head(s) and pressure regulator or pump/s even after the system has been switched off using the main switch or the emergency stop. This especially applies to multi--hose configurations between pump/s and application head/s. Prior to maintenance and repair work it is therefore essential to ensure that all liquid adhesive application system components are depressurized as follows: 1. Release input pressure in front of pump by shutting off customer compressed air supply. 2. Release any remaining system pressure behind the pumps by manually operating the application heads. ecure pneumatically-- and hydraulically--operated equipment against uncontrolled movement. witch off system electrically. WARNING: ome voltage is still present in the control cabinet even after equipment has been turned off at the main switch. Complete the following steps prior to maintenance or repair: 1. Disconnect external power supply. 2. Lock out external power supply. 3. Check no voltage is present. 4. Ground and short. 5. Cover nearby live sections. If liquid adhesive application system is left idle for extended periods (e.g. overnight or long breaks) Nordson recommends applying Vaseline to the application head nozzles to prevent them from drying out and becoming blocked as a result. Only use genuine Nordson parts. E 1995 Nordson Corporation

21 afety Cleaning NOTE: Always refer to the liquid adhesive manufacturer s Material afety Data heet or material information sheet before working with any cleaning fluids. WARNING: Never clean any aluminium part or flush any system using halogenated hydrocarbon fluids. Examples of common halogenated hydrocarbons are: dichloromethylene, 1,1,1--trichloroethylene and perchlorethylene. Halogenated hydrocarbons may react violently with aluminium parts. Never use an open flame to clean the system or its components. Check that (warm) water can be used to clean the liquid adhesive system components, possibly with the addition of household washing--up liquid. If this is not possible, use only the cleaning fluid stated in the liquid adhesive manufacturer s information. If the manufacturer recommends heating the cleaner, note the flash point. Ensure sufficient room ventilation to draw off vapors. WARNING: Fire, open flames and smoking are prohibited when cleaning fluids are used. Observe all explosion prevention regulations. Cleaning fluids may only be heated using temperature controlled and explosion--protected heaters. Disposal must be according to the waste key in the DIN afety Data heet. Liquid adhesives or residue, solvent or separating agents must not be released into open waterways. In the case of a leak or spillage, contain liquid and if necessary use an absorbant material e.g. sawdust to soak it up; then proceed according to the relevant waste disposal regulations. If the liquid adhesive application system is to be idle for an extended period, the entire system should be flushed and outlets sealed with Vaseline. Warm water is usually used to flush application systems with which water based liquid adhesives are processed. If the liquid adhesive manufacturer specially recommends a flushing agent, the manufacturer s safety and disposal details must be followed. E 1995 Nordson Corporation

22 1-8 afety 9. Liquid Adhesives As there is a wide variety of liquid adhesives available with different compositions and characteristics, it is impossible here to give an exhaustive list of safety notes reflecting the typical characteristics of liquid adhesives. The use of liquid adhesives in Nordson s liquid adhesive application systems therefore requires reference to the liquid adhesive manufacturer s documents beforehand. Information relating to safety aspects e.g. concerning solvent content, hazards and countermeasures in the event of liquid adhesive coming into contact with skin or mucous membranes are contained in the technical data sheets and the DIN afety Data heets from the manufacturer. NOTE: Always refer to the manufacturer s Material afety Data heet or material information before working with any liquid adhesives. It may be necessary to refer to the manufacturer s notes on the use of materials from a third party. These may be required for processing a liquid adhesive, but hazards arising from their use are not necessarily mentioned by the manufacturer of the liquid adhesive. Liquid adhesives may still give off vapors when they are processed correctly. The smell produced can cause some annoyance. This is especially true where liquid adhesives are used that contain solvent, thus requiring the use of breathing equipment e.g. a filter. If the prescribed processing conditions are not followed, harmful decomposition products may develop. Therefore, the vapors must be removed. Wash hands well before breaks and when work is finished. If liquid adhesive comes into contact with eyes or mucous membranes, rinse well with water -- especially the eyes. Change damp clothes, and seek medical advice if it is swallowed. Disposal must be according to the waste key in the DIN afety Data heet. Liquid adhesives or residue, solvent or separating agents must not be released into open waterways. In the case of a leak or spillage, contain liquid and if necessary use an absorbant material e.g. sawdust to soak it up; then proceed according to the relevant waste disposal regulations. If solvents or separating agents are used to process a liquid adhesive, follow the safety and disposal information from the manufacturer. E 1995 Nordson Corporation

41 Maintenance / Repair 5-1 ection 5 Maintenance / Repair WARNING: Allow only qualified personnel to perform the following tasks. Observe and follow the safety instructions in this document and all other related documentation. Your liquid adhesive gun is easy to maintain and almost maintenance-free. Under normal operating conditions all components have a long durability. WARNING: Disconnect power supply! WARNING: Disconnect adhesive supply! WARNING: Always use protective gloves! Generally observe the following issues: Make sure that the material to be applied is in a clean, filtered condition. The control air should be clean when fed into the apparatus. Individual operating conditions and different application material require a corresponding minimum effort for maintenance. For outside cleaning procedures, e.g. nozzle tips, never use sharp metallic tools but rather soft brushes. When doing repair or maintenance work keep your working space as well and the gun as clean as possible. Clogged guns should be flushed thoroughly with an adhesive-compatible detergent. Particularly if needle, seals or nozzle should be replaced. In case of major repair work, the gun should be removed from the equipment. Remove pressure and detach material lines before servicing equipment.

42 5-2 Maintenance / Repair 1. Preventive Maintenance Cleaning the Liquid Adhesive Gun Gun cleaning is not required as long as air is prevented from entering the hydraulic section and coming into contact with the adhesive for an extended period of time (usually about 30 minutes, although it varies with the adhesive used). If an orifice or a gun become clogged, however, it can be easily cleaned. NOTE: Never disassemble the gun if the adhesive inside is solidified! It is highly possible that sensitive component parts will be damaged. We recommend immersing the module in warm water so that the adhesive can soften. Repeat this procedure several times, if necessary. If it is still impossible to disassemble the gun, send it to us for repair. NOTE: Do not remove needle and seat out of the armature sleeve if not absolutely necessary because the needle has the ideal position after being switched a number of times. 2. Periodic Maintenance Purge and rinse the application system with water 2 times a year. The liquid adhesive gun should be kept clean, remove glue residue and dirt daily. 3. Liquid Adhesive Gun Disassembly- WM 801P- WARNING: Disconnect equipment from the line voltage. WARNING: ystem and material pressurized. Release pressure. Failure to observe this may result in serious injury. 1. Place a container of water near the disassembly area. 2. Ensure that the work area and all tools are clean. NOTE: Foreign particles can damage the seats and/or cause leaks in the gun. 3. Place a small container under the gun. Then seal the hose opening with a tape or a plug so that no adhesive can flow out.

Observe and follow the safety instructions in this document and all other related documentation. Your liquid adhesive gun is easy to maintain and almost maintenance-free. Under normal operating conditions all components have a long life. WARNING: Disconnect power supply! WARNING: Disconnect adhesive supply! WARNING: Always use protective gloves! Generally observe the following issues: Make sure that the material to be applied is in clean, filtered condition. The control air should be clean when fed into the apparatus. Individual operating conditions and different application material require a corresponding minimum effort for maintenance. For outside cleaning procedures, e.g. nozzle tips, never use sharp metallic tools but rather soft brushes. When doing repair or maintenance work keep your working space as well and the gun as clean as possible. Clogged guns should be flushed thoroughly with an adhesive-compatible detergent. Particularly if needle, seals or nozzle should be replaced. In case of major repair work, the gun should be removed from the equipment. Remove pressure and detach material lines before servicing equipment.

50 6-2 Troubleshooting NOTE: Refer to section 5 for disassembly procedures. Problem Possible Cause Corrective Action Refer to Liquid adhesive gun does not deposit adhesive ystem pressure too high No voltage Dried adhesive Check the hydraulic system pressure. When the pressure exceeds 48 bar (700 psi) the gun might not open due to high hydrostatic forces. Lower system pressure and trigger the gun. When the gun is activated a voltage of 24 VDC should be measured over the leads ot the coil. If no adhesive comes out of the gun check the connection to the triggering device. Remove the module from the gun. Disassemble module and take out the armature and inspect the components for dried adhesive. NOTE: Never use a steel brush or sharp tools, you might damage the metallic parts. Problem Possible Cause Corrective Action Refer to Adhesive leaks from nozzle Dried adhesive at seat or needle tip Remove the module from the gun. Disassemble module and take out the armature. Inspect seat and needle tip for dried adhesive. If dried adhesive is found on the components, place them under cold, running water to clean them. NOTE: Never use a steel brush or sharp tools, you might damage the metallic parts. In severe cases a hard brush or a wooden chip can be used. Problem Possible Cause Corrective Action Refer to Blocked nozzle or pattern plate Dried adhesive. Remove nozzle or pattern plate and place it under cold, running water. Use a brush or similar instrument to remove adhesive deposit. NOTE: Never use a steel brush or sharp tools, you might damage the metallic parts.
