Safety1-4



S Prior to installation, check intended location and surrounding area forany potential hazards during operation.

S All electrical, pneumatic, gas and hydraulic connections andinstallation of all system components may only be carried out byqualified personnel. Observe installation instructions for componentsand accessories.

S Equipment must be properly grounded and fused according to therated current consumption (see ID plate).

S Cables which run outside the system must regularly be checked forwear or damage.

S Power supply wire gauge and insulation must be sufficient to handlerated current consumption.

S Cables must never be squeezed or pinched. Do not locate cables orhoses in high traffic areas.

S Check liquid adhesive feed hoses, screwed connections andcompressed air lines regularly for leaks. These are to be replaced atthe first signs of cracks, brittleness etc. Release system pressurecompletely beforehand.

WARNING: Failure to install the system properly, and espe-cially failure to ensure electrical, pressurized and high pressurefeed connections are made correctly may result in serious injuryor death.

The system should only be operated when it is in working order. It shouldonly by operated by qualified persons following all regulations valid forliquid adhesive systems.

S Never allow the system to be operated by personnel under theinfluence of substances which reduce their reaction times, or who arenot able to operate the equipment for physical reasons.

S Prior to each startup of the system, check protection and warningdevices and make sure they are fully functional. Do not operate theequipment if these devices are not functioning properly.

S When the removal of safety equipment is required for installation,maintenance or repair, it must be reconnected immediately uponcompletion of the work.

S In a humid environment, only equipment featuring a correspondingclass of protection may be operated.

S Do not operate the system in an explosive environment.

6. Operation

Safety 1-5



S Keep parts of the body and clothing away from rotating parts. Do notwear loose articles of clothing when operating or servicing equipmentwith rotating parts. Remove wrist watches, rings, necklaces or similarjewelry and pin up or cover long hair before performing any work onor with the equipment. The wearing of protective gloves may provehazardous in certain circumstances where rotating parts are presentand may therefore be forbidden.

S To carry out measurements on the substrate or system components,switch off parent machine and/or system and wait until the equipmentcomes to a standstill.

S Never point guns or applicator nozzles at yourself or other persons.

WARNING: An operator or service technician working with theequipment should be aware of the less--obvious dangers thatoften cannot be completely minimized at production sites:

S Pressurized system components

S The possibility that electrical potentials may remain in the systemafter the system was de--energized

S Liquid adhesive vapors

S Hydraulically or pneumatically operated system components

S Uncovered winding parts

If the system malfunctions, switch it off immediately.

S Turn the main switch off, or use emergency stop switch or similarsafety feature as provided.

S After equipment has come to a standstill and before reoperating it,have it repaired by qualified personnel.

6. Operation (contd.)

Less-obvious Dangers

Action in the Event of SystemMalfunction

Safety1-6



Allow only qualified personnel to perform the procedures described in thisdocument. Work should only be carried out on a completelydepressurized system, following all safety procedures.

NOTE: Depending on the configuration of the liquid adhesive applicationsystem, high pressure may remain between application head(s) andpressure regulator or pump/s even after the system has been switchedoff using the main switch or the emergency stop. This especially appliesto multi--hose configurations between pump/s and application head/s.

S Prior to maintenance and repair work it is therefore essential toensure that all liquid adhesive application system components aredepressurized as follows:

1. Release input pressure in front of pump by shutting off customercompressed air supply.

2. Release any remaining system pressure behind the pumps bymanually operating the application heads.

S Secure pneumatically-- and hydraulically--operated equipment againstuncontrolled movement.

S Switch off system electrically.

WARNING: Some voltage is still present in the control cabineteven after equipment has been turned off at the main switch.Complete the following steps prior to maintenance or repair:

1. Disconnect external power supply.

2. Lock out external power supply.

3. Check no voltage is present.

4. Ground and short.

5. Cover nearby live sections.

If liquid adhesive application system is left idle for extended periods (e.g.overnight or long breaks) Nordson recommends applying Vaseline to theapplication head nozzles to prevent them from drying out and becomingblocked as a result.

S Only use genuine Nordson parts.

7. Maintenance / Repair

Safety 1-7



NOTE: Always refer to the liquid adhesive manufacturer’s MaterialSafety Data Sheet or material information sheet before working with anycleaning fluids.

WARNING: Never clean any aluminium part or flush any sy-stem using halogenated hydrocarbon fluids. Examples of com-mon halogenated hydrocarbons are: dichloromethylene,1,1,1--trichloroethylene and perchlorethylene. Halogenated hy-drocarbons may react violently with aluminium parts.

S Never use an open flame to clean the system or its components.

S Check that (warm) water can be used to clean the liquid adhesivesystem components, possibly with the addition of householdwashing--up liquid. If this is not possible, use only the cleaning fluidstated in the liquid adhesive manufacturer’s information. If themanufacturer recommends heating the cleaner, note the flash point.

S Ensure sufficient room ventilation to draw off vapors.

WARNING: Fire, open flames and smoking are prohibitedwhen cleaning fluids are used. Observe all explosion preventionregulations. Cleaning fluids may only be heated using tempera-ture controlled and explosion--protected heaters.

S Disposal must be according to the waste key in the DIN Safety DataSheet. Liquid adhesives or residue, solvent or separating agents mustnot be released into open waterways. In the case of a leak or spillage,contain liquid and if necessary use an absorbant material e.g.sawdust to soak it up; then proceed according to the relevant wastedisposal regulations.

S If the liquid adhesive application system is to be idle for an extendedperiod, the entire system should be flushed and outlets sealed withVaseline. Warm water is usually used to flush application systemswith which water based liquid adhesives are processed.

S If the liquid adhesive manufacturer specially recommends a flushingagent, the manufacturer’s safety and disposal details must befollowed.

8. Cleaning

Safety1-8



As there is a wide variety of liquid adhesives available with differentcompositions and characteristics, it is impossible here to give anexhaustive list of safety notes reflecting the typical characteristics ofliquid adhesives. The use of liquid adhesives in Nordson’s liquid adhesiveapplication systems therefore requires reference to the liquid adhesivemanufacturer’s documents beforehand.

Information relating to safety aspects e.g. concerning solvent content,hazards and countermeasures in the event of liquid adhesive coming intocontact with skin or mucous membranes are contained in the technicaldata sheets and the DIN Safety Data Sheets from the manufacturer.

NOTE:

S Always refer to the manufacturer’s Material Safety Data Sheet ormaterial information before working with any liquid adhesives.

S It may be necessary to refer to the manufacturer’s notes on the use ofmaterials from a third party. These may be required for processing aliquid adhesive, but hazards arising from their use are not necessarilymentioned by the manufacturer of the liquid adhesive.

S Liquid adhesives may still give off vapors when they are processedcorrectly. The smell produced can cause some annoyance. This isespecially true where liquid adhesives are used that contain solvent,thus requiring the use of breathing equipment e.g. a filter.

S If the prescribed processing conditions are not followed, harmfuldecomposition products may develop. Therefore, the vapors must beremoved.

S Wash hands well before breaks and when work is finished.

S If liquid adhesive comes into contact with eyes or mucousmembranes, rinse well with water -- especially the eyes. Changedamp clothes, and seek medical advice if it is swallowed.

S Disposal must be according to the waste key in the DIN Safety DataSheet. Liquid adhesives or residue, solvent or separating agents mustnot be released into open waterways. In the case of a leak or spillage,contain liquid and if necessary use an absorbant material e.g.sawdust to soak it up; then proceed according to the relevant wastedisposal regulations.

S If solvents or separating agents are used to process a liquidadhesive, follow the safety and disposal information from themanufacturer.

Description 2-3




The wall mounted pneumatic pumps WM 360 can be used independentlyof standardized adhesive containers because the adhesive is drawn bymeans of a suction hose. Purge of excess adhesive (e.g. during start up)is performed via a purge hose which feeds directly to the adhesivecontainer. The pump is mounted on the wall by means of a bracket. Thismakes it easy to remove for cleaning and maintenance work. Theadhesive suction hose has a maximum length of 1.5 m (59.0 in.).

The standard unit has a pump ratio of 12 : 1. By implementing aretrofitting kit, the pump ratio can be reduced to 6 : 1 (refer to SectionParts).

To reduce the possibility of corrosion, all pump surfaces which come intocontact with moisture are made of stainless steel or special plastics. Thepumps are constructed to enable easy handling and for maximumdurability and service life.

Stainless steel containers with level control and automatic refill areavailable on request. A range of (automatic) pressure regulators areavailable for selection according to the application.

NOTE: In the following sections, the pneumatic pump is referred tosimply as the pump. This is a collective term which encompasses the airmotor, hydraulic and filter assemblies and the optional adhesive pressureregulator.

The units described in these instructions are standard version units-unless otherwise specified. Units with individual equipment can bedifferent in details. However, in such cases, we will make every effort toenclose specific information.

Please refer to the updated Bill of Material which is packed with yourequipment.

Description 2-5




This section explains the principles of functioning of the pattern control inconnection with a wall mounted WM 360 pneumatic pump according tothe adjacent diagram.

Adhesive is to be applied to a substrate (10). The substrate is transportedon the conveyor belt of the production machine (also referred to asparent machine) and passes the guns (8 and 21). When the substratearrives, the photo cell (22) detects the leading edge and the controllerWM 408 initiates the selected program.

NOTE: In general, a production machine is a machine in whichNordson-WALCOM equipment for adhesive application is integrated (forexample a packaging machine). The term production machine means thesame as “parent machine” which may appear in other Nordson literature.

The encoder (6) is mechanically coupled to the conveyor belt of theproduction machine via a gear box. It supplies one pulse per mm. Thisenables easy programming of the WM 408 pattern controller because allnecessary lengths can be entered in millimeters.

After the photo cell has triggered the program, the controller calculateswhen the adhesive guns (8, 21) have to be activated, according to thespeed of the production machine.

The adhesive is fed from the adhesive container (18) via the pump andfilter (24 and 23) to the adhesive pressure regulator (19). Depending onthe position of the diaphragm in the pressure regulator, the adhesivearrives at the guns (8 and 21) with a high or low pressure.

The lower part of the principle drawing depicts a liquid adhesive detectionsystem WM 500 (14 - 16). It serves for checking the application ofadhesive and can be used for controlling subsequent equipment, such asthat for separating or marking waste.

See Fig. 2-3.

The compressed air is supplied to the air motor via a quick-snapconnector on the pressure regulator (1) where it is adjusted to anapplication-specific pressure of 40 - 400 kPa (0.4 - 4 bar / 6 - 58 psi).

Compressed air enters the 5/2 directional control valve (2) which directs itvia an air distributor (3) through boreholes (↑↓) to the upper and lowercylinders (5 and 6). The alternation of air entry into the cylinders isinitiated when the pistons pass the valve control bores (4 and 7).

The compressed air moves the pistons up and down, resulting in acorresponding up and down movement of the hydraulic assembly pistonrod (8, Fig. 7-1).

CAUTION: Ensure that the air motor starts up with a very lowpressure.

CAUTION: Only use unlubricated, dry and filtered compressedair for operating the air motor.

Description2-8




See Fig. 2-2.

The liquid adhesive in the container is pumped by the hydraulic assem-bly (16) through the suction hose (14) to the filter assembly (10). Foreignparticles which may be in the adhesive material are filtered here.

Finally, the liquid adhesive is fed through the filter outlets directly to thesystem gun(s) or the inlets of the optional adhesive pressure regulator(WM 35X or WM 370 series). The outlets of these regulators areconnected to the adhesive guns.

For pressure relief and/or for maintenance (cleaning), the liquid adhesivecan be re-directed by means of the purge valve (19) into the hydraulicassembly and through the adhesive purge hose (13) to the container.

See Fig 8-7.

The hydraulic portion from the pump is a dual action type. As the plungerrod (1) moves up, the large ball (11) check valve is lifted off its seat,sucking adhesive into the chamber from the glue suction hose. The smallball (8) check valve remains on its seat during this time because thepump shaft is moving up. The upward movement of the plunger (7) at thelower end of the plunger rod pushes the adhesive above it into the highpressure hose and from there to the adhesive filter.

As the plunger rod (1) moves down, the adhesive pressure forces thelarge ball (11) check valve against its seat and the small ball (8) off itsseat, allowing the adhesive to move up the pump cylinder and into thehigh pressure hose.

NOTE: The pump is a bleeding type pump, this means that the pumpallows a small portion of adhesive to leak past the rod seal (3). Theadhesive then pushes against a ball (35) and flows back through thehose (27) into the adhesive container. Even when no adhesive isdispensed by the glue guns the plunger rod will move up and down whenair input pressure is applied on the air motor. This will especially show upwhen running water or a low viscous adhesive through the pump.

Section 4Operation


NOTE: The following information is particularly important for theprocessing of liquid adhesives but is also applicable to other materials:

S Always pre-test the unit before applying it for its ultimate purpose.

S The surface to be bonded should be at room temperature and free ofdust, grease and moisture.

S The suitable material, optimum working conditions, and possiblepre-treatment of the substrate must be determined by testing.

S Some substrates contain softeners and other components which maybecome volatile later. Some surfaces are treated with wax, lubricants,etc. Bonding may fail immediately or later if pre-treatment/tests arenot carried out.

NOTE: Not all types of adhesive are compatible. Degradation of theadhesive resulting in function faults and unit damage may be the result ofimproper use of the adhesive.

We are only the supplier of the pneumatic pump and cannot be heldliable for damages to equipment, hoses or guns if adhesives congeal dueto incorrect handling.

In case of doubt and/or if planning to change the adhesive, pleasecontact the adhesive manufacturer, our head office or one of ourrepresentatives.

Operation4-2




Familiarize yourself with the Emergency Shutdown devices on yourLiquid Adhesive Application System.

WARNING: Switch off the system immediately in any emer-gency situation.

1. Activate the nearest Emergency Shutdown device (e.g. EmergencyOFF button or main switch with Emergency OFF function).

2. When the unit has come to a standstill, and before switching it onagain, ensure the fault is cleared by qualified personnel.

Ensure that all connections have been properly made -- including thosewhich do not concern the pneumatic pump directly.

1. Turn the air pressure regulator knob fully counterclockwise so no airpressure is currently applied to the pump.

2. Connect the pump to the compressed air supply with a quick-snapconnector.

3. Insert the pneumatic pump adhesive hoses in the adhesive containerand open the adhesive purge valve (19, Fig. 2--2).

4. Slowly open the pressure regulator to supply air pressure to thepneumatic pump.

5. Regulate the pump so that adhesive flows smoothly out of the purgevalve and no more air bubbles are in the adhesive material.

6. Activate the adhesive guns and adjust the control unit so thatadhesive material flows smoothly out of the gun(s) and purge valve.

7. Close the purge valve.

8. Connect pattern plates or nozzles to the gun(s).

9. Check all connections for any signs of leakage; tighten them, ifnecessary.

3. Emergency Shutdown

4. Initial Setup

Operation 4-3




10. Set the required adhesive output.

-- observe the system’s adhesive manometer (if provided).

-- evaluate the application-specific adhesive quantity.

The adhesive output depends on:

S Viscosity of the adhesive material

S Orifice diameter

S Pump pressure

NOTE: Reducing the pump pressure, by turning the pressure regulatorknob counterclockwise, reduces the adhesive output.

Increasing the pump pressure, by turning the pressure regulator knobclockwise, increases the adhesive output.

CAUTION: Do not exceed the maximum permissible pumppressure. Too high a pressure may change the characteristicsof the adhesive.

CAUTION: Due to the design of the high pressure filter (with aball valve), adhesive pressure is not completely relieved purelyby setting the pneumatic pressure to 0. Also ensure that thepurge valve is also opened to guarantee complete adhesivepressure relief. Failure to do this may cause the adhesive toescape unexpectedly.

1. Check the level of adhesive in the container.

2. Refill or change the container, if necessary.

3. Set the pump air pressure to the required level. Observe theinstructions above.

1. Reduce pump pressure to zero using the air pressure regulator.

2. Open the purge valve to ensure complete adhesive material pressurerelief.

Always observe the following basic points:

S Make sure that the material to be applied is in a clean, filteredcondition.

S Individual operating conditions and different application materialrequire a corresponding minimum effort for maintenance.

S Use soft brushes, never sharp metallic tools, to clean the outside ofthe equipment, e.g. nozzle tips.

S When carrying out repair or maintenance work, keep the workingspace as well as the equipment as clean as possible.

S Before servicing equipment, relieve any pressure and disconnectmaterial feed lines.

WARNING: Disconnect the power supply to all system compo-nents!

WARNING: Disconnect compressed air and adhesive supply!

WARNING: Wear safety goggles and protective gloves.

WARNING: System and material are pressurized. Disconnectcompressed air supply.

Maintenance5-2




Remove dirt particles and adhesive material residue from the pump.

Internal Cleaning

Intervals for a periodic internal cleaning (flushing) of the pump must bedetermined by customer-specific work experience, e.g. in respect of theadhesive material used.

1. Set the pump pressure to 0 bar.

2. Place a container filled with water under the pump.

CAUTION: Due to the design of the high pressure filter (with aball valve), adhesive pressure is not completely relieved purelyby setting the pneumatic pressure to 0 bar. Ensure that thepurge valve is also opened to guarantee complete adhesivepressure relief. Failure to do this may cause the adhesive toescape unexpectedly.

3. Connect the pump to the compressed air supply.

4. Close the purge valve (19, Fig. 2-2).

5. Increase the pump pressure to approx. 40 kPa (0.5 bar/7.25 psi).

6. Trigger the liquid adhesive gun(s).

7. Set pump pressure to 0 bar again.

8. Open the purge valve (19, Fig. 2-2).

9. Increase the pump pressure to 40 kPa (0.5 bar/7.25 psi). The water ispumped back into the container via the filter.

10. Set the pump pressure to 0 bar again.

11. Ensure the adhesive material pressure is fully relieved beforeremoving the pump from the water container.

CAUTION: Make sure that no water remains in the pump afterflushing. Mixing water and liquid adhesive material may affectthe adhesive quality.
