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.

Residual Risks

Description 2-3


WM 408Issued 01/99


The WM 408 is a user-friendly pattern and pressure controller. It is usedto control electric and pneumatic solenoid valves which are integrated inadhesive guns. The control is intermittent and independent of theproduction machine speed.

In addition, up to four proportional valves with integrated amplifyingelectronics for pressure control can be triggered.

The unit can be easily programmed via a touch-sensitive keyboard.Programming is menu-controlled.

A menu here takes the form of a branched program structure where thecorresponding functions can be selected. All programming steps aredisplayed on an easy to read LCD in a selectable language. See SectionSpecifications for a reference list with display texts.

The following figure shows the principle use of a WM 408 patterncontroller in a complete system.

Adhesive is to be applied to a substrate (10). The substrate is conveyedon the transport belt of the production machine (also referred to as parentmachine) and passes the guns (8 and 21). When the beginning of asubstrate arrives, the photo cell (22) detects the leading edge. Thecontroller WM 408 initiates the selected program.

NOTE: In general, a production machine is a machine in which Nordsonequipment for adhesive application is integrated (for example a packingmachine). The term production machine means the same as “parentmachine” which may appear in other Nordson literature.

The encoder (6) is mechanically coupled to the transport 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 mm.

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 pump and filter(24 and 23) to the adhesive pressure regulator (19). Depending on theposition of the diaphragm in the pressure regulator, the adhesive arrivesat the guns (8 and 21) with a high or low pressure.

WM 408Issued 01/99


Pull-in and drop-off delays of the solenoid valves and differences inviscosity can lead to adhesive misalignment, especially at highproduction machine speeds (Fig. 2-2). This misalignment can becompensated for by means of corresponding programming steps. Themisalignment can be distinguished between pull-in misalignment whenthe adhesive gun is started, and drop-out misalignment when the gun isstopped (Fig. 2-2). Compensating is very simple because themisalignment need only be measured and entered in mm.

In case of an emergency stop, adhesive may flow out and soil theproduction machine. This can be compensated for by programming astop speed. If the machine operates below this speed, all guns aredeactivated. A start speed can also be programmed. When the machinereaches this speed all guns are activated.

In addition, the controller has three or four alarm outputs, which can beused as visual and acoustic alarm indicators.

The lower part of the principle drawing depicts a liquid adhesive detectionsystem (13 - 17). It serves for checking the application of adhesive andcan be used for controlling following facilities such as those forseparating or marking of waste.

The encoder can be driven by a friction wheel, which bears directly onone of the belts of the production machine. Driving by means ofgearwheels or toothed belts is possible alternatively.

We recommend using an encoder bracket with a friction wheel for easyinstallation and adjustment of the encoder (see Fig. 3-2). Also refer toSection Parts.

Choose a gear ratio which makes sure that one revolution of the encodercorresponds to a machine feed movement of exactly 500 mm. Thisguarantees that the control unit can evaluate the production machinespeed correctly and a good production is obtained.

Between one and three photo cells can be used for triggering theapplication process. The photo cells must be carefully and properlymounted if the pattern controller WM 408 is to operate perfectly.

S For dynamic applications, the bending radius must not be less than6 times the sheath diameter.

S For static applications, the bending radius can be a minimal 3 timesthe sheath diameter, provided the fiber optics is not kinked.

S The fiber optics sheaths must not be exposed to tension or torsion.

S The glass-fibers must be protected from damage at the light-emissionend.

In addition, the photo cell inputs can be connected via hardware. For thispurpose, a circuit board with two four-pole DIP switches is located on theinside of the rear panel (on the right side). The right DIP switch is usedfor setting the photo cells, the left switch is used for setting the datatransfer.

1. Remove the two long rubbered feet on the rear side of the unit.

2. Unscrew the four screws and remove the frame.

3. Unscrew the ten screws and tip the rear panel down

CAUTION: The rear panel is connected to the integratedelectronics with some wires.

NOTE: The photo cell inputs 1 and 2 are reserved for the use of a liquidadhesive detection system.

NOTE: The pattern controller WM 408 uses the photo cell inputs 3 to 5.In the display they are called P1 to P3.

NOTE: The representation of the DIP switch corresponds to thearrangement on the rear panel.

The illustration on the left shows the standard mode:Up to 3 photo cells can be connected, each of which can be accessedseparately.

The illustration on the right shows a possible variation:Photo cell inputs 3 and 4 are connected in parallel, i. e. a photo cellconnected to input 4 also communicates directly with input 3, and viceversa.

NOTE: If photo cell 1 provides more than one additional trigger pulsewhile the program is running, the display in the adjacent diagram (215)will appear. This may appear with cartons with holes.

Alarm output “lamp” is activated and LED (5) lights up (see ChapterMessages and Alarms in Section Maintenance / Troubleshooting /Repair).

While the program is running, photo cells 2 and 3 are not accessed foradditional trigger pulses. For this reason, they are suitable for triggeringsubstrates that would cause additional pulses (such as cartons withholes).

NOTE: If this fault occurs, the application process continues, regardless.

The controller uses the minimum carton length to calculate the shortestperiod which a photo cell may be covered by a carton. The valves closewhen the covering period is too short, caused by cartons being too shortor running slanted, or by unwanted triggering signals (e.g. by smallpieces of paper). This prevents the machine being soiled. This value canbe adjusted for all 3 photo cells.

NOTE: When using this function, there must not be any holes in thecarton in the area of the photo cells because it is not possible todifferentiate between a hole and the end of a carton.

Internal Monitoring

In addition to the normal triggering function for the application ofadhesive, each photo cell can be used to monitor the minimum cartonlength. If the carton length falls below the minimum value, all the valvestriggered by the respective photo cell close immediately. The message”LENGTH FAULT!” appears for approx. 1 second.

External Monitoring

A free photo cell (not used for triggering purposes) is used exclusively formonitoring the minimum carton length. If the carton length falls below theminimum value, all the valves triggered by this photo cell close immedia-tely. The message ”LENGTH FAULT!” appears.

Range of values: 0 to 9999 mm

WM 408Issued 01/99


In order to achieve a constant adhesive bead both at low and highproduction machine speeds, the adhesive pressure necessary iscontrolled according to the production machine speed.

For this purpose, the minimum adhesive pressure is assigned to the startspeed of the production machine (see Start Glueing above in this section)and the maximum adhesive pressure is assigned to the maximum speedof the production machine (cf. Fig. 4-5).Range of values: 0 to 700 m/min

The preset delay and adhesive patterns shift at high production machinespeeds. This shift is called misalignment. It depends on the pull-in anddrop-out characteristics of the valves and the viscosity of the adhesiveand increases with mounting production machine speed. To compensatefor this effect, the valves are activated and deactivated earlier (valvecompensation).Range of values: 0 to 700 m/min






6. Press key (3) or key (6) to set the maximum possible productionmachine speed between 0 and 700 m/min for the product to be glued.


8. Press key (3) or key (6) to select the production machine speed(0 to 700 m/min) at which the misalignment and the correspondingcompensation values for the valves are determined.

9. Press key (5) until the adjacent ”Run” (100) or ”Glue Stop”display (101) appears. LED (5) goes out.

In order to achieve a constant adhesive bead both at low and highproduction machine speeds, the parameters minimum pressure,minimum speed, maximum pressure and maximum speed have to betuned to each other. A test run is necessary for an adequate result.

In order to compensate for misalignment, it is measured for thecorresponding channels at a certain production machine speed (seeValve Compensation) and then programmed.

Since the misalignment in the first two cycles of an application progressmay differ from misalignment of the remaining cycles, the first two cyclesof each channel can be compensated additionally.

In order to achieve a constant adhesive bead both at low and highproduction machine speeds, the necessary adhesive pressure iscontrolled according to the production machine speed. Standardizedsignals of 0 to 20 mA are sent to the pressure outputs PRS1 to PRS4.

The minimum pressure is the pressure at which the adhesive beginsflowing continuously. The minimum pressure is connected to theminimum production machine speed (see Start Glueing Above).

The maximum pressure is the pressure necessary for achieving a usefuladhesive bead at the highest production speed possible. Higherpressures cause an adhesive bead that is too thick.

This chapter lists some important notes for programming using theapplication pattern below as an example.

Two different adhesive traces are to be applied to a substrate inaccordance with the representation provided below. The applicationpattern is to be stored as program No. 40 and the operator guideline is tobe in English. Available are:

S A pattern controller WM 408, a photo cell and an encoder

S Two identical adhesive guns

S A proportional valve, an adhesive pressure regulator and a pump withfilter

S Power supply connection, oil-free compressed air, adhesive

The substrate is to be glued with a constant bead both at a minimumproduction machine speed of 8 m/min and at any higher speed, up to themaximum speed possible (in this example, the maximum speed isassumed as 220 m/min).

The current necessary for the minimum pressure that the proportionalvalve has to render is assumed as 6 mA, the current for maximumpressure is assumed as 12 mA.

If the production machine is stopped abruptly (for example because of anemergency stop), all valves have to be deactivated as soon as possiblein order to prevent the machine from being soiled by adhesive flowingout. (In this example, the valves are deactivated if the speed falls below12 m/min).

When the machine is restarted, the application process is to be startedagain at a speed of 8 m/min.

Message appears if the required application pattern cannot be achievedwith the preset compensation values due to a production machine speedthat is too high. There are several reasons possible, depending on theselected compensation:

1. The 1st glue start is located before the trigger signal due to the pull-incompensation.

2. An adhesive gap is reduced to zero. The pull-in compensation is setto such a value that there is no gap to the previous application.

3. The glue end is located before the glue start. The drop-outcompensation is set to a value higher than the pull-in compensation.

Message appears if there is no supply voltage of +15 V for the photocells and the encoder.

The alarm outputs “Buzzer” and “Lamp” are activated and LED (8) lightsup. The alarm output “Lamp” is active as long as there is a voltage supplyfailure.

Message appears if the production machine activated the machinecontact but the encoder does not send any pulses. This function has tobe activated first (see External Glue Stop & Encoder Control in SectionOperation).


Message appears if photo cell 1 sends more than one additional triggerpulse while the program is running. This may be the case with cartonswith holes.


While the program is running, photo cells 2 and 3 are not accessed foradditional trigger pulses. For this reason, they are suitable for triggeringsubstrates that would cause additional pulses (such as cartons withholes).

NOTE: If this fault occurs, the application process is continued,regardless.

This message appears when the photo cell is activated during operationfor a period shorter than it should be, in relation to the productionmachine speed and minimum carton length.

This may be caused by cartons which are too short or run at a slant, orby small pieces of paper which initiate unwanted triggering signals.

Alarm outputs ”Buzzer” and Lamp” are activated, LED (4) lights up andadhesive application is stopped. (Refer to Minimum Carton Length in theSection Operation).
