19 Introduction 2-9 WARNING: Risk of electrical shock. Failure to observe may result in personal injury, death, or equipment damage. The electrical cabinet can be opened for installation, maintenance and repair. Store the included key such that it is accessible only to qualified and authorized personnel. The system may not be operated when the electrical cabinet is open. Temperature Setbac Serves to protect the adhesive and save energy during interruptions in production or work stoppages. Setback value and setback period are adjustable. Temperature control The temperature is measured by sensors and is electronically controlled by the control system. NOTE: Toavoiddamagingthemachinebystartingupwhentoocold,the heating zone temperatures must first be checked and compared with the nominal temperatures set. After longer downtimes, the extruder heat--through time must expire after the set nominal temperatures have been reached (minimum 10 minutes after temperature release, adhesive-dependent). Also refer to manual Control System. Undertemperature Interlock The undertemperature interlock prevents the unit or system from being started up before the adhesive has exceeded the temperature setpoint minus undertemperature value. However, every time initial heating occurs, the interlock is not released until theactualtemperatureis10 C(5.4 F)belowthetemperaturesetpoint. Under-temperature Indication The undertemperature interlock locks the motors, solenoid valves and, in some cases, other components of the hot melt application system. Refer to the wiring diagram to determine which components are locked. Overtemperature Indication/ Shutdown The independently operating overtemperature shutdown mechanisms protect the unit and adhesive from overheating. For overtemperature shutdown, the heating and motor are switched off. The red indication lamp Collective fault lights up.

The flow and volume canbereadofffromthewatermeter.thetemperatureinthefeedzonewill now increase slightly during the heating up process. After production has started, the temperature increases again depend on the product and frictional heat of the screw. During operation, the temperature will stabilize and remain relatively constant as long as speed, water volume and water supply temperature remain constant. If the temperature increases in the cooling zone(over--temperature warning), check immediately why the temperature has increased and if thereisalackofwater,whichcanbeseenfromthewatermeter,correct immediately.ifthecausecannotberectifieddirectlyorifthereisnowater flowatallandthetemperaturehasincreasedbyanother20 C,thesystem mustbeshutdownandthefaultrectified.

30 2-20 Introduction Mode of Operation The hopper is filled with a sufficient supply of hot--melt granules that ripple down to the screw feeding. Suitable free--flowing properties have to be presupposed. Thegearmotorstartstorotatethescrew.Bymeansofthescrewchannels, the granules are being moved towards the pump station(respectively the hose connection flange). The high motor performance has a considerable share in the heat generation of the extruder. Cooling In order to maintain free--flowing properties and to prevent an unwanted reaction of the hot--melt before processing, the cylinder situated under the granule hopper(feeding area) is constantly being cooled down(cooling liquid: water). One hose connection each is destined to ensure water supply and drain respectively. Flow direction has no effect on the cooling properties. Heating The whole length of the cylinder is mantled by heating cuffs(electrical resistance heating). The real values of each heating zone can be adjusted and read at the temperature controllers. Temperature is being measured by sensors(pt100 or Fe/Ko). Screw Thescrewgeometrycausesadefinedcompression. Heatingenergyandfrictionalheatbothcombinetothemeltingofthe granule. Forthisreason,thescrewisbeingsub-dividedinto3different sections: 1. Transportation zone 2. Compression zone 3.

Delivery is made with the parameters that ensure the optimum speed for the continuous rating guaranteed for the extruder. Based on the multiplicity of available extruder adhesives, an adhesive--specific temperature profile of the glue used in the system is beingdefinedasarule. Our extruders always fulfil current safety rules. The operator is additionally protected by the integration of important control functions. These comprise purely functional as well as system protective measures. Pressure Regulation The extruder is equipped with two independent pressure regulating and controlling systems. ElectronicPressureRegulation In automatic mode, this control continually reads the adhesive pressure in the compression zone of the cylinder and adjusts the screw speed in accordance with the digitally set operation pressure(= set pressure). In case the actual value ecxeeds the set pressure, an electronic safety cut--outshutsdownthemotorinmanualaswellasinautomaticmode.

Maintenance of Heating Cartridges In order to maintain the heating--up as well as the temperature stability of the system, the heating cartridges should be controlled regularly and exchanged if necessary. Maintenance intervals depend on the type of application as well as other individual factors and have therefore to be defined and if need be adjusted by the user/ operator himself. Maintenance work on heating cartridges should only be done by a skilled electrician(qualified labour)! Measuring Heating Cartridges Inordertochecktheheatingcapacityofazone,eachheatingcartridgehas to undergo a current measurement. Currentdependsontheheatingcapacityofthecartridgeandhastobe calculated individually(formula: P = U x I). Informationastotheheatingcapacityofazonecanbefoundinthe electrical diagram. Before checking the heating elements, verify that the cartridge in question is being controlled and that the safety switch is active. If current consumption is missing or too low, the defective cartridge has to be exchanged. Otherwise the system would be subject e. g. to temperature variations and longer heating--up times NordsonDeutschlandGmbH ExtruderEEX100 P/N

62 5-6 Maintenance Exchange of Heating Cartridge Defective heating cartridges can easily be located by using the constructional/ electrical diagrams and have to be exchanged against the same type. Before exchange, system has to be dead or the respective circuit breakers have to be switched off(current interrupted). Over- temperature Thermostat The over--temperature thermostats(1) serve as an automatic switchoff in case the over--temperature shutdown of the temperature controller does not function properly. NOTE: Depending on the type of adhesive used, the overtemperature thermostatsofthetankmayneedtobeadaptedtothemaximumprocessing temperature of the adhesive(this may mean replacing it).

Lubricant Recommendations for Threaded Connectors All threaded connectors exposed to high temperatures must be correctly treated with suitable lubricants. The correct selection of solid lubricants facilitates easy tightening of all connections and loosening in assembly work. All connections, screws and nuts must be cleaned before applying the recommended Molykote Paste HSC Plus. This paste must be applied extremely thinly with a hard brush. The Molykote lubricant film must be applied without any gaps to thread flanks and roots, and head/nut contact surfaces. Fault Rectification Faults during production should not arise if these operating instructions are observed carefully, the system operated correctly and the required maintenance work implemented as necessary. P/N Extruder EEX NordsonDeutschlandGmbH

65 Maintenance 5-9 For heating elements with ceramic insulation: During the initial heating procedure check and retighten, where necessary, the clamping screws at regular intervals until the operating temperature has been reached. Any tightening required must be carried out with particular care. Too high a pre--stress can lead to the ceramic stones being damaged. The aluminium cooling elements located between the heating elements must also be checked for correct fit and retightened if necessary. Fig. 5-5 Heating cuffs NOTE: WhenmountingtheHeatingcuffs,theyaretobefastenedwitha tightening torque of 1,5Nm! WARNING: Danger of burns from hot components! Wear protective gloves, clothing and shoes! For heating elements with micanite insulation: During the initial heating procedure, check the tightening bolts for correct fit and retighten if necessary. Check frequently for even and tight fit. All aluminium cooling elements, if present, must also be checked for tight fit and retightened if necessary after the initial start--up.
