Avoid inhalation.
Applicators 3 Function The applicators in the series are used for spiral shaped adhesive application. A heated hose from a melter supplies the single applicator with adhesive. The patented spray process (Controlled Fiberization, CF) mixes adhesive and spray air in the applicator nozzle. The spray air is heated by flowing through one or more sintered metal inserts (Integrated air heater, patent pending). Sample Application, Labeling 3 2 1 Fig. 1 1 Applicator 2 Labels to be glued 3 Applicator with slot nozzle,e.g. series LabelCoat Applicator
4 Applicators Series Overview The series includes various blocks and spacers that can be combined with one another to achieve the desired nozzle spacing and quantity of control modules: 1 2 3 4 7 6 5 35 25 35 40 mm Fig. 2 Sample configuration 1 Spray air block 2 Spacer (10 mm) 3 Sandwich block 4 Hose connection block 5 Nozzle 6 Control module 7 Solenoid valve Control module For the minimum configuration with only one control module, an unheated hose connection end plate (not shown) is used in place of the hose connection block (4).
Applicators 5 The above example shows three additional blocks (Sandwich blocks) as well as three spacers (2 x 10 mm, 1 x 15 mm). This results in the nozzle spacing shown in the illustration. Each block has a control module (6) with a nozzle (5) and a corresponding solenoid valve (7). 1 2 Spray Air Block The spray air block is heated by four heater cartridges, 75 W each. The spray air, which is switched via a solenoid valve (1), is connected to the spray air block. The spray air is heated by flowing through one or more sintered metal inserts. There is a threaded pin (2) on the spray air block to fasten the applicator to a suitable holder. The spray air block is equipped with a power cable for the voltage supply to the heater cartridges. The power cable contains a thermal sensor (Ni 120) mounted in the block. A B 2 3 2 3 Hose Connection Block / Hose Connection End Plate NOTE: For applicators with only one control module, an unheated hose connection end plate (B) is used in place of the hose connection block (A). The hose connection block is heated by four heater cartridges, 75 W each. The hose connection (3) is - different than shown - attached in the back on newer models. There is a threaded pin (2) on the hose connection block and the hose connection end plate to fasten the applicator to a suitable holder. The hose connection block is equipped with a power cable for the voltage supply to the heater cartridges. The power cable contains a thermal sensor (Ni 120) mounted in the hose connection block. Sandwich Block A sandwich block is heated by two heater cartridges, 75 W each. The spray air is heated by flowing through a sintered metal insert. There are two models (01 and 02) available, differing only in the mirror image positioning of the smooth and threaded bores (Refer to illustration). If more than one sandwich block is used, the two models must be arranged alternately.
6 Applicators Splash proof Model The spray air block, sandwich block, hose connection block and power cable are also available in splash proof models (IP54). The spacers and the hose connection end plate are always splash proof. Also refer to section Spare Parts. ID Plate NOTE: Applicators assembled by the customer using components on hand do not have a Nordson applicator ID plate. Only the individual components have ID plates with order numbers. - Applicator type ID# Nordson order number S/N Serial number WATTS Power consumption W = Watt VOLTS Operating voltage V = Volt Explanation of Type Designation The model shown above is used as an example.

8 Applicators Installation ATTENTION: Allow only qualified personnel to perform the following tasks. Observe and follow the safety instructions in this document and all other related documentation. Unpacking Unpack carefully. Then check for damage caused during transport. Reuse packaging materials or dispose of properly according to local regulations. Transport NOTE: The applicator is a high precision, valuable part. Handle very carefully! Protect the nozzle from damage. Storage Do not store outside! Protect from humidity and dust. Do not lay unit on the nozzle. Protect the nozzle from damage. Disposal When your Nordson product has exhausted its purpose and/or is no longer needed, dispose of it properly according to local regulations.
Applicators 9 Installing 1 1 Install the applicator in the appropriate place in the production machine. Observe the following: Do not operate in a potentially explosive atmosphere Protect from humidity, vibrations, dust and drafts Ensure access to parts relevant for maintenance and operation Protect the nozzle from damage. There is one threaded pin (1) each on the spray air block and the hose connection block to fasten the applicator to a suitable holder. Exhausting Adhesive Vapors Ensure that adhesive vapors do not exceed the prescribed limits. Exhaust material vapors if necessary. Ensure sufficient ventilation of the installation location.
10 Applicators Electrical Connection ATTENTION: Risk of electrical shock. Failure to observe may result in personal injury, death, or equipment damage. Laying Cable ATTENTION: Ensure that cables do not touch rotating and/or hot components. Do not pinch cables and check regularly for damage. Replace damaged cables immediately! Cordset The spray air block and the hose connection block are always equipped with a power cable for the voltage supply to the heater cartridges. Each power cable contains a thermal sensor (Ni 120) mounted in the block. Maximum Capacity No more than 600 W heating capacity can be connected for each power cable. Of this amount, 300 W is for the four heater cartridges in the block, meaning that up to four more heater cartridges (from two sandwich blocks) can be connected per power cable. This means that, if more than four sandwich blocks (more than six control modules) are used, a third power cable must be connected directly to the fifth sandwich block. Connecting Applicator ATTENTION: Observe operating voltage! Refer to section Technical Data. Heating 1. Connect one power cable to the heated hose receptacle and the other directly to the melter. 2. Use safety clips (when available) to secure the plug connection. Solenoid Valves The solenoid valves for the spray air and the control modules are usually triggered by a control unit (e.g. Eclipse). Refer to separate control unit manual. CAUTION: Trigger the solenoid valve only when the applicator is heated to operating temperature! Seals in the control module can become damaged if the adhesive is too cold.
Applicators 11 Pneumatic Connection Connecting Control Air The applicator may only be connected to pressure-controlled and conditioned compressed air. 1 The quality of the compressed air must be at least class 2 as stipulated by ISO 8573-1. This means: Max. particle size 1 m Max. particle density 1 mg/m 3 Max. pressure dewpoint -40 C Max. oil concentration 0.1mg/m 3. NOTE: Ensure that control air is on at all times. Among other functions, it keeps the nozzle closed when EMERGENCY OFF occurs or when the system comes to a standstill. This prevents hot material from dripping out of the nozzle. 1. Connect a controllable air supply to the control air fitting (1). NOTE: The control air connection (present on spray air block and hose connection block) is initially sealed with a plug. Extract the plug from one of the blocks and replace with the hose coupling included in delivery. 2. Set control air pressure to approx. 4 to 6 bar (0.4 to 0.6 MPa / 58 to 87 psi). The exact pressure must be determined for each application. Operating with Lubricated Compressed Air The applicators / control modules can also be operated with lubricated compressed air. NOTE: Once the air has been lubricated, it must always be lubricated; the lubricated compressed air will wash out the original lubricant on the solenoid valves and the control modules. Nordson recommends: Oil P/N Klüber Unisilkon TK002/50 316578
12 Applicators Connecting Spray Air 1 The spray air may never be lubricated. It should be conditioned with a compressed air filter with water separator. The air conditioning unit cleans and dries the compressed air. CAUTION: The filter mesh size may not exceed 5 m; otherwise the sintered metal inserts that heat the spray air will become clogged. 1. Connect the spray air hose to the spray air connection fitting (1) on the system. 2. Set spray air pressure to approx. 3 to 4 bar (0.3 to 0.4 MPa / 43.5 to 58 psi). The exact pressure must be determined for each application.
Applicators 13 Connecting Heated Hose ATTENTION: Hot! Risk of burns. Wear heat-protective gloves. Using Second Open-end Wrench Use a second open end wrench when connecting and disconnecting the hose. This prevents the hose connection on the unit from turning. 1 2 3 Connecting If cold material can be found in the hose connection, these components (1, 2) must be heated until the material softens (approx. 80 C, 176 F). 1. First connect the hose (3) electrically to the unit. For more than one hose: Every hose connection is allocated to a corresponding receptacle. Do not mistakenly exchange! 2. Heat the system and hose to approx. 80 C (176 F). 3. Screw on heated hose. NOTE: Close unused hose connections with proper Nordson port plugs. Disconnecting ATTENTION: The system and material are pressurized. Relieve system pressure before disconnecting heated hoses. Failure to observe can result in serious burns. ATTENTION: Hot! Risk of burns. Wear safety goggles and heat protective gloves. 1. Turn off material supply. 2. Place a container under the nozzle(s) of the applicator. 3. Activate the solenoid valves electrically or manually. Repeat this procedure until no more adhesive flows out. 4. Re use the material or dispose of it properly according to local regulations.
14 Applicators Operation ATTENTION: Allow only qualified personnel to perform the following tasks. Observe and follow the safety instructions in this document and all other related documentation. Triggering Solenoid Valves The solenoid valves for the spray air and the control modules are usually triggered by a control unit (e.g. Eclipse). Refer to separate control unit manual. CAUTION: Trigger the solenoid valve only when the applicator is heated to operating temperature! Seals in the control module can become damaged if the adhesive is too cold. Setting Temperatures The procedure for setting the temperatures is described in the temperature controller manual. Temperature controllers are not part of the applicator. They can be located e.g. in the electrical cabinet of the melter or in a separate electrical cabinet. NOTE: The spray air block and the hose connection block each contain one temperature sensor. With the maximum of two sandwich blocks heated together, they form one heating zone each. Maximum Operating Temperature 200 C / 392 F. NOTE: The maximum operating temperature may not be exceeded. Nordson will assume no warranty or liability for damage resulting from incorrect temperature settings.
Applicators 15 Setting Control Air Pressure The control air pressure for the control modules is set for each application on an external air pressure control valve. The air pressure control valve is not part of the applicator. NOTE: Ensure that the applicator is supplied with control air at all times. The control air keeps the control modules closed when EMERGENCY OFF occurs or when the system comes to a standstill. This prevents hot material from dripping out of the nozzle. Maximum Control Air Pressure 6 bar / 0.6 MPa / 87 psi NOTE: The maximum control air pressure may not be exceeded. Nordson will assume no warranty or liability for damage caused by an incorrect pressure setting.
16 Applicators Adjusting Spray Pattern 1 2 The spray pattern is optimized by alternately setting: Adhesive inlet pressure (on unit feeding adhesive) Nozzle stem stroke adjustment (1) Spray air pressure (on separate pressure controller) Spray air pressure [with adjusting screw (2)]. 1. Initially set spray air pressure to approx. 3 bar / 43.5 psi / 0.3 MPa. 2. Turn the adjusting screws (2) for the spray air pressure all the way to the left to open completely. 3. Trigger the solenoid valve; adhesive flows out. 4. Optimize spray pattern by modifying the air pressure on the separate pressure controller. 5. Perform fine adjustment of spray air pressure with adjusting screw (2) to adapt the spray patterns of the individual nozzles to one another. Setting Nozzle Stem Stroke + - All control modules are equipped with a nozzle stem stroke adjustment. It is used for fine adjustment of the adhesive application quantity or the adhesive flow quantity. ATTENTION: Hazard! The stem stroke adjustment knob has no upper setting limit. If compressed air is connected, never turn the adjusting knob all the way up; it may jump out. CAUTION: The nozzle stem stroke may be adjusted only when the applicator is heated! Failure to observe can cause damage to seals. NOTE: The stem stroke adjustment knob has no upper setting limit; starting from the bottom, it may only be turned a maximum of 2¼ turns upward. This corresponds to a nozzle stem stroke of maximum 1.2 mm. Failure to observe can result in - among other things - increased wear and malfunctioning. Experience has shown that a stroke adjustment of max. 0.5 to 0.6 mm (which corresponds to 1 turn) has proven to be sufficient. Nozzle stem stroke Counterclockwise (+) = increase Flow rate Increase Clockwise (-) = decrease Decrease
