� When changes or modifications have been made by the customer

� In defective condition

� In a potentially explosive atmosphere

� When values stated under Technical Data are not complied with.

The application head may not be used to apply the following materials:

� Explosive and flammable materials

� Erosive and corrosive materials

� Food products.

2 Hot melt application head EP 30


Residual RisksIn the design of the unit, every measure was taken to protect personnelfrom potential danger. However, some residual risks can not be avoided.Personnel should be aware of the following:

� Risk of burns! The application head is hot.

� Risk of burns! The hot melt adhesive that comes out of the nozzle is hot.

� Risk of burns when connecting and disconnecting heated hoses.

� Risk of burns when conducting maintenance and repair work for whichthe application head must be heated up.

� Inhalation of potentially hazardous hot melt adhesive vapors.

Note on Manual� The position numbers in the illustrations do not correspond to the

position numbers in the technical drawings and parts lists.

� The illustrations show only the essential components of the applicationhead. All other components and details can be found in the includedtechnical drawings (Refer to Parts List).

Description of Components / Functioning (contd.)

Solenoid valveNOTE: The solenoid valves may only be triggered or activated when theapplication head has been heated up! Failure to observe may causedamage to the nozzle stem seals in the control modules.

The solenoid valves are operated by an electronic control unit that ensuresthat the solenoid valves open and close at the right times.

Control ModuleThe control module precisely opens and closes the adhesive supply to thenozzle by pneumatically raising or lowering the nozzle stem. A compressionspring ensures that the application nozzle is closed when pressure drops,preventing adhesive from being applied.

HeatingThe application head is heated with electrical heater cartridges. Thetemperature is continuously measured by temperature sensors and iscontrolled with electronic temperature controllers.

Temperature controllers are not part of the application head.

InstallationWARNING: Allow only qualified personnel to perform the following tasks.Observe and follow the safety instructions in this document and all otherrelated documentation.

UnpackingUnpack carefully. Then check for any damage caused during shipping.Reuse packaging materials or dispose of properly according to localregulations.

TransportThe application head is a high precision, valuable part. Handle verycarefully! Protect the nozzle from damage.

StorageDo not store outside! Protect from humidity and dust. Do not lay applicationhead on the nozzle. Protect the nozzle from damage.

DisposalWhen your Nordson product has exhausted its purpose and/or is no longerneeded, dispose of it properly according to local regulations.

InstallationWhen installing the application head, the following points should beobserved in order to avoid unnecessary effort later.

� Protect from humidity, vibrations, dust and drafts.

� Ensure access to parts relevant for maintenance and operation.

� Install/attach the application head to/in the parent machine with themounting bracket. To achieve optimum adhesive application, duringassembly ensure that the distance and, when appropriate, the anglebetween the nozzle and the substrate can be varied.

� When installing the application head, ensure that cables, air hoses, andheated hoses can not be bent, pinched, torn off or otherwise damaged.



Exhausting Adhesive VaporsEnsure that adhesive vapors do not exceed the prescribed limits. Exhaustadhesive vapors when necessary. Provide sufficient ventilation of thelocation where the application head is installed.

Electrical Connections

WARNING: Risk of electrical shock. Failure to observe may result inpersonal injury, death, or equipment damage.

Laying CableWARNING: Do not pinch cables and check regularly for damage. Replacedamaged cables immediately!

Electrically Connecting Application HeadThe application head is connected electrically by inserting the plugs into thecorresponding receptacle of the melter or a terminal box. Secure the plugwith the clamp if necessary.

Connecting Solenoid ValvesDepending on the specific design of the hot melt application system, thesolenoid valves on the control modules are controlled either by an externalpower supply, e.g. control unit, or through the solenoid valve control leads ofthe heated hose. Secure the plug with the clamp if necessary.

NOTE: Observe the voltage stated on the ID plate of the solenoid valve.



Compressed AirNordson recommends using dry, controlled and non-lubricated compressedair.

Operating with Non-lubricated Compressed AirWhen an application head is connected to a compressed air system inwhich the compressed air has previously been lubricated, simply ceasing tolubricate the air is not sufficient. The oil remaining in the compressed airsupply will reach the solenoid valves and the control modules and wash outthe lubricant/oil from these parts, substantially decreasing the lifetime of theunits.

NOTE: It must be ensured that the compressed air supply to the applicationheads has been converted to absolutely non-lubricated operation.

NOTE: No oil from a possible defective compressor may be permitted topenetrate the compressed air supply.

NOTE: Nordson will assume no warranty/liability for damage resulting fromunpermitted, temporary lubrication.

Conditioning Compressed AirThe quality of the compressed air must be at least class 2 as stipulated byISO 8573−1. This means:

� Max. particle size 1 �m

� Max. particle density 1 mg/m3

� Max. pressure dewpoint −40 °C / −40 °F

� Max. oil concentration 0.1mg/m3.

Pneumatic Connections1. Connect customer’s air supply to to the inlet of the air conditioning unit.

Maximum air pressure:

10 bar 1 MPa 145 psi

2. Connect control modules to the air conditioning unit.

3. Set control air pressure:

Approx. 5 to 6 bar Approx. 0.5 to 0.6 MPa Approx. 72.5 to 87 psi

NOTE: The exact pressure must be determined for each application.

Connecting Heated HosesWARNING: Hot! Risk of burns. Wear heat-protective gloves.

ConnectingIf cold adhesive can be found in the hose connection (1) and/or hose fitting(2), these components must be heated until the adhesive softens (approx.80 �C, 176�F).

1. First connect the hose (3) electrically to the unit.

2. Heat the unit and hose to approx. 80 �C (176 �F).

3. Screw the heated hose onto the unit.

Fig. 3

Disconnecting

Relieving Pressure1. Set motor speed(s) to 0 min-1 (rpm); switch off motor(s).

2. Place a container under the nozzle(s) of the application head.

3. Trigger the solenoid valves electrically or manually. Repeat thisprocedure until no more adhesive flows out.

4. Dispose of adhesive properly according to local regulations.

Second Open-jawed WrenchUse a second open-jawed wrench when connecting and disconnecting theheated hose. This prevents the hose connection from turning.

Fig. 4



OperationWARNING: Allow only qualified personnel to perform the following tasks.Observe and follow the safety instructions in this document and all otherrelated documentation.

Triggering Solenoid ValveCAUTION: Trigger the solenoid valves only when the application head isheated to operating temperature!

Setting TemperaturesNOTE: The temperature setting is determined by the processingtemperature prescribed by the adhesive supplier. The maximum operatingtemperature of the product described here may not be exceeded.

The application head temperature required is set on the melter.

The basis for temperature selections are the values stipulated by the hotmelt manufacturer.

Nordson will assume no warranty or liability for damage resulting fromincorrect temperature settings.

Setting Control Air PressureThe control air pressure is set to suit each application on an air conditioningunit. The air conditioning unit with pressure control valve is not part of theapplication head.

Set control air pressure:

5 to 6 bar 0.5 to 0.6 MPa 72.5 to 87 psi

NOTE: The maximum control air pressure may not be exceeded.

The exact pressure must be determined for each application.

Nordson will assume no warranty or liability for damage resulting fromincorrect pressure settings.
