FunctionNOTE: The applicator is part of an application system. Also refer to page 5, Illustration (Examples).

The adhesive flows from a melter through a heated hose then a filter (2) andinto the applicator.

The adhesive is applied to the spine from underneath as soon as theApplication control module (6) is triggered (opened). The Retrosuctioncontrol module (5) sucks the adhesive out of the application slot (1) as soonas the application control module closes. This ensures exact adhesiveedges.

The application width can be set continuously from 1 to 60 mm.

Note: Not all models have all components



Constant Pressure Controller

The outlet adhesive pressure is controlled pneumatically via the constantpressure controller. The adhesive pressure or the quantity emitted can beadapted to the speed of the binder with a pattern controller (e.g. LA 404‐2)and a proportional valve.

NOTE: On models without constant pressure controller, the quantity emittedcan be adapted to the speed of the binder by adjusting the pump speed ofthe melter.

Heating

Electrical heater cartridges are used to heat the unit. The temperature iscontinuously measured by temperature sensors and regulated by electronictemperature controllers usually located in the electrical cabinet of the melter.

Overtemperature Shutdown by Thermostat

Thermostats in the filter and in the body switch off the heater at approx230 °C or 180 °C, depending on the model.

Adapter plate

An adapter plate with plug has been added to applicators P/N 7154401 and7154402 since 02/2013. Remove the plug if a pressure sensor is to beinstalled.

The screw heads for fastening the filter block and adapter plate to theconstant pressure controller are located behind the electrical equipmentcover on the filter block.

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

Using Second Open-end Wrench

Use a second open-end wrench when connecting and disconnecting theheated hose. This prevents the hose connection on the unit from turning.

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.

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

3. Screw on heated hose.

Disconnecting

ATTENTION: System and material pressurized. Relieve system pressurebefore disconnecting heated hoses. Failure to observe can result in seriousburns.

ATTENTION: Hot! Risk of burns. Wear goggles and heat-protective gloves.

Refer to page 19, Relieving Pressure.



Observe When Starting up the SystemNOTE: Depending on the system, the pressure controller and the connectedcomponents may be controlled automatically. Thus it is essential to refer tothe technical documentation of the system components!

For initial startup it is important to remember that the hydraulic connectionsand the pressure controller must first fill with material before controlling canoccur.

Setting Outlet Pressure (CPR)

The outlet pressure is set by applying pneumatic control pressure. The outletpressure reacts proportionally, but it is higher due to the transmission ratio.

NOTE: For correct control response, the material pressure at the inlet mustbe at least 0.5 MPa (5 bar) higher than the outlet pressure.

ATTENTION: The maximum control pressure permitted is a factor of thetransmission ratio and the maximum inlet pressure of the subsequent systemcomponents. Refer to Technical Data.

CAUTION: Risk of damage! To prevent hardened material from damagingseals, control pressure may not be applied in heated systems until thematerial has reached the setpoint temperature.

Triggering with Proportional Valve

Application of control pressure through an electro‐pneumatic proportionalvalve enables the outlet pressure to be controlled by an electrical signal. Thisis helpful in line speed-controlled application systems to adapt the adhesivequantity emitted to the web speed of the parent machine.

Both the proportional valve for run-up in the Dura series and the proportionalvalve in the Versa series provide maximum air pressure of 4 bar.

Trigger the proportional valve with at least 10 to 12 % of the maximum airpressure of 4 bar (= 100 %).

The proportional valve is not triggered until the melter is ready for operation.With older melters (only Dura), the kit 7193063 may need to be installed.

Bleeding

Example: replacing filter cartridge. After replacing the filter cartridge, bleedthe applicator so trapped air can escape.

Bleed before beginning production. Refer to the sectionMaintenance/Bleeding in this manual.

Calibrating Application Width DisplayATTENTION: Hot! Risk of burns. Wear heat-protective gloves.

1. Heat applicator.

2. Use the handwheel Application width (3) to close the application slot untilthe left and right guide plates (1 and 2) touch one another.

3. Release the setscrew (4).

4. Turn the set collar (5) until the value 0000.00 appears in the displayApplication width (6).

5. Tighten the setscrew again.



Motorizing Application Width AdjustmentObserve the following when mounting a motor drive in place of thehandwheel for adjusting the application width:

� Avoid radial load to the spindle

� Use the coupling:Using a coupling that can be separated (e.g. a simple claw coupling)between the motor drive and spindle makes disassembly formaintenance purposes easier (Refer to page 23, Lubricating Plan).

� Comply with these values:

NOTE: * The recommended maximum speed is 1 mm/sec for allapplicators. Higher speeds increase wear to seals and bearingsurfaces. Since spindles of different pitches have to be used, differentspeeds result.



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

Important When Using Polyurethane ApplicationMaterials (PUR)

It is imperative that the following guidelines are complied with whenprocessing polyurethane application materials (PUR):

� Wear respiratory protection when the maximum permissibleconcentration of hazardous substances is exceeded.

� Before prolonged standstill of the application system, purge with asuitable cleaning agent. Use only a cleaning agent recommended by thematerial manufacturer.

� Close open material connections airtight.

When the system is to cease operation for only a short time, it suffices to coatthe application slot generously with grease.

CAUTION: Use only special high‐temperature grease. Refer to page 20,Processing Materials! Any other grease may cause the PUR material tocross‐link.

Triggering Solenoid ValvesCAUTION: Trigger the solenoid valves only when the applicator is heated tooperating temperature! Seals in the application control module and theretrosuction control module can become damaged if the material is too cold.

Setting TemperatureThe procedure for setting the temperatures is described in the temperaturecontroller manual. Temperature controllers are not part of the applicator.They can be located e.g. in the electrical cabinet of the adhesive feeding unitor in a separate electrical cabinet.

Maximum Operating Temperature

Refer to ID plate, Oper.temp.max

NOTE: When setting the temperature, the temperature prescribed by the hotmelt adhesive manufacturer is decisive. The maximum operatingtemperature for the product described here and the heated systemcomponents may not be exceeded.

Nordson will grant no warranty and assume no liability for damage resultingfrom incorrect temperature settings.

Applying Hot Melt AdhesiveFactors that have a significant influence on application quality:

� Viscosity of the adhesive (The heat effect and the duration thereofinfluence the viscosity)

� Set application width (Medium application widths have proven to requirea lower adhesive pressure than small or large application widths)

� Book spine condition.

Setting Application Width

CAUTION: The application width may be adjusted only when the applicationcontrol module is closed and the applicator is heated to operatingtemperature.

1. Set the application width to the width of the book spine + 0.5 mm:

2. Re‐adjust application width during operation if required.

Setting Application Thickness

Refer to page 9, Adjusting.

Daily ShutdownTo prevent the PUR material to be processed from hardening, open surfacesmust be coated with grease.

CAUTION: Use only special high‐temperature grease. Refer to page 20,Processing Materials. Any other grease may cause the PUR material tocross‐link.

1. If necessary, remove adhesive from nozzle with wooden or plasticspatula, or wipe off with a cloth.

2. Set the application width to approx. 10 mm.

3. Generously cover the application slot with grease.

NOTE: For extended standstill:

1. Detach the guide plates

2. Set minimum application width.

3. Generously cover the application slot with grease.
