2 9- WARNING! Allow only personnel with appropriate training and experience to operate or service the equipment. The use of untrained or inexperienced personnel to operate or service the equipment can result in injury, including death, to themselves and others, and damage to the equipment. Introduction This section provides troubleshooting, repair, parts, and specification information for applicators with UM Universal modules. The UM module, either directly or through the use of an adapter, can dispense adhesive in a variety of spray applications, including Controlled Fiberization (CF), Summit, SureWrap, and Signature applications. Table 9- shows the available UM modules. Figures 9- and 9- show the key components of the UM module parts family.

4 9-4 Overview Dispensing modules apply adhesive to a product. All modules are air-actuated (or air-open), meaning that an air supply controlled by a solenoid valve is required to open the module. s are then spring-closed. In air-open, spring-close (AOSC) modules, the actuating air lifts a needle-and-piston assembly inside the module, thus opening the module and allowing adhesive to flow through the nozzle onto the product. When the actuating air shuts off, a spring returns the needle-and-piston assembly to the closed position, closing the module. A separate air supply is used to supply pattern air to the module; this air enters the pattern air inlet and is directed onto the adhesive exiting the nozzle, creating the desired spray pattern. UM OptiStroke modules are compatible with the OptiStroke needle detection system. The special OptiStroke air cap on the module accepts the required sensor. The OptiStroke needle detection system electronically verifies the opening and closing time of a module/valve combination. It is used as a service and maintenance tool to measure compensation times and sends an alarm or stops the line during a stroke fault. The detection system automatically prevents production loss due to the absence of adhesive on the substrate caused by a slow or non-operating module/valve. Contact your Nordson representative for additional information on the OptiStroke needle detection system. Figure 9-3 shows the flow of adhesive and air through a UM module. Figure 9-4 shows the key parts of a module.

6 9-6 Service This part of Section 9 provides module-related service procedures. Synchronizing Multi- Applicator Adhesive Output NOTE: This procedure applies only to adjustable modules. Fixed and OptiStroke modules are not adjustable. A loading screw located in the top of the modules can be used to fine-tune the alignment of the adhesive patterns of multi-module applicators, as shown in Figure 9-5. You will need the following items: S 5 / 8 -in wrench S cap/nozzle/filter multi-tool (part 05967) NOTE: Refer to Parts for the part numbers of parts, tools, and supplies. CAUTION! Do not use the loading screw to increase or decrease the amount of adhesive output (flow rate). To change the flow rate, adjust the melter pump speed. 3 4 Figure 9-5 Results of module loading screw adjustments. Target area. Pattern too long 3. Pattern too short 4. Desired pattern length Issued 7/ E 0 Nordson Corporation

7 9-7 See Figure 9-6. To adjust a loading screw, loosen the locking nut () at the top of the module and hold it loosely in place with a 5 / 8 -inwrenchwhile turning the loading screw () with the multi-tool; then tighten the locking nut. Turn the loading screw as follows: S S To decrease the length of a pattern, turn the loading screw clockwise. This shortens the length at both ends of the pattern. To increase the length of a pattern, turn the loading screw counterclockwise. This increases the length at both ends of the pattern. NOTE: If the module loading screw is tightened too much, the module will not dispense any adhesive. To return a loading screw to the factory setting, loosen the locking nut, turn the screw clockwise until it bottoms out, back the screw out three full turns (counterclockwise), and tighten the locking nut.

8 9-8 Replacing a You will need the following items: S appropriate tools, including a torque wrench S drain pans and disposable rags S replacement module S replacement O-rings (if needed) S O-ring lubricant (if needed) S anti-seize lubricant NOTE: Refer to Parts for the part numbers of parts, tools, and supplies. Remove the. Heat the system to application temperature.. Relieve system pressure. Refer to Relieving System Pressure in Section 0, Filter. 3. Trigger the applicator solenoid valves to relieve any remaining pressure. 4. Shut off the module-actuating air. 5. Decrease the pattern air pressure. Leave just enough air pressure to prevent adhesive from entering the pattern air outlet. 6. SeeFigure9-7.Removethemodulemountingscrewsandthenremove the module. Discard the module O-rings.

9 9-9 Install the. Wipe off any adhesive on the applicator, especially around the air passages.. Ensure that the module O-rings are lubricated and properly inserted in the O-ring bores on the back of the replacement module. 3. Coat the module mounting screws with anti-seize lubricant and use them to secure the replacement module to the applicator. Tighten the screws to 3.4 NSm (30 in.-lb). 4. Restore the system to normal operation. For best results, tighten the module mounting screws again after the applicator reaches application temperature. Rebuilding a To rebuild a module, order a module rebuild kit and follow the instructions provided in the kit. Refer to Service Kits.
