THERMAL SPECIFICATIONS

The compact construction of the solidary PUMP-TANK block with a bottom pumpoffers total control of the Hot-Melt temperature throughout the hydraulic circuit. At thesame time a rapid fusion speed has been achieved while using minimal electricalconsumption.

Due to the hermetically sealed tank via floating lid, smoke escape is avoided andthe adhesive is protected from early oxidation. A wide- angle lid opening allowsadhesive loading from any position. The ample-sized loading port makes loading Hot-Melt easy.

PNEUMATIC AND PUMPING SPECIFICATIONS

The pump system features a continuous steady flow thanks to a well-designedblock of tank-pump-pneumatic system:

• The operation via piston pump with the exclusive compensation large volumevalve allows a totally uniform hydraulic pressure for the adhesive.

• The patented pneumatic assembly has a fully mechanized design which featuresstrength and durability. The high-speed piston change significantly helps maintaincontinuous steady flow of the adhesive.

• The recirculation of the Hot-Melt avoids burnt residue build-up as well as wear onthe mechanical components.

SAFETY

It features constant self-monitoring and display of damaged components as well asprotection against overheating.

The independent signal for the input electrical power at external supply to theParent Machine Interlock allows control of the Parent Machine start-up when theadhesive has reached running temperature.

Three highly performing filter systems for the adhesive.

WARRANTY CARD

In order to plan and decide the siting for the Central Units, factors of a practical,technical and economic nature must be kept in mind. If there is any doubt, contacta SERVICE TECHNICIAN.

Practical factors

We advise you to install the Central Unit Applicator in an easily accessi-ble place meaning not only its controls and filters, but also its Hot-Melt filling tank.

At the same time, care must be taken to avoid objects falling into the filling tankand into the hard adhesive container provided by your regular supplier.

It must also be kept in mind that the Central Unit lets off heat when it is running,so the operate must work at a safe distance form the Unit.

Technical factors

Fig. 6 shows the dimensions and the weights of the different Central Unit models.

a. A secure mounting must be guaranteed. The structure designated formounting must be designed to be able to hold the weight of the Central Unit plusthe adhesive load with no problem.

b. The Central Unit Applicators are designed to support vibrations fromthe machinery. However, it is advisable to reduce this factor to a minimum as in thelong run, these vibrations will cause negative effects on all the mechanical,electrical and electronic components.

Economic factors

Take care to situate the Central Units as close as possible to the desiredapplication in order to minimize the length of the hoses. However, the technicalrequirements for the hoses must be respected as far as the radius of maximumflexibility is concerned (see technical sheet attached to hoses).

The ambient operating temperature must be between:

- 5 and + 50 ° CIn humid working conditions or in areas where strong chemical agents such as

bleach are used, our series' anti-moisture device protects the bondingsystem from early corrosion.

In dusty working areas it is essential to avoid getting dirt into the tank while fillingwith adhesive. The lid must always remain closed.

After having installed the Central Units, the guns must be properly installed in theposition desired, then the hoses are hooked up. The hoses are placed in theirdesired position, and then must be fastened with clamps.

The following step is to install all of the remaining fittings. The flexibility radiuscannot be less than 150 mm. At the same time any axial bending of the guns mustbe avoided. For mobile hose installation, ask our service technicians.

Every gun comes equipped with a heat insulator (2) which must be placedbetween the gun and the mounting retainer. This insulator avoids heat diffusionfrom the gun and guarantees its proper heating function.

Once the accessories have been installed in their correct positions, They mustthen be connected to the Central Unit Applicators, following the diagram below(Fig. 10). The following models of connectors are available:

WARNING: In order to mechanically hook up the hoses, the guns and theCentral Unit Applicators one to another, we highly recommend that the componentsbe at approximately the same temperature as the softening point temperature ofthe adhesive, because to the contrary, there exists DANGER OF STRIPPING THETHREADS.

WORK WITH THERMAL PROTECTIVE GLOVES

Mechanically hook up each hose to its corresponding gun, screwing the hoseconnector to the gun male connector. In order to do this, it must be kept in mindthat the side of the hose that is screwed to the gun is the one that has theconnector with eight female poles, where the gun will be electrically connectedafter. The first turn of the connector must be done manually without the aid of anytools, so that this goes smoothly into its correct position. After tighten theconnector with a wrench.

Connect each hose to the Central Unit mechanically. To do this, the pump caps,located at the back of the Series 200-ST Central Unit Applicator, must beremoved by using a 6mm Allen's wrench (see Fig. 10). Screw the connector to thehose, then hook up the hose following the same procedure as for the gun.

OPERATING MANUAL FOR THE CENTRAL UNIT

APPLICATORS

IV. 2







WARNING

This manual summarizes the main components for basic bonding operations.For information about temperature programming, see the manual,"TEMPERATURE SET AND CONTROL".

This section describes loading the adhesive, using the pneumatic pressure,monitoring the tank adhesive level, and at the end we include some general,practical recommendations for using the Central Unit Applicator.

Loading will be done from the top part of the tank, which has a Teflon coatingand which is sufficiently accessible in order to load the adhesive. It will also beequipped with a lid having a specially designed floating closure system whichguarantees a perfectly smooth vacuum for the whole surface.

The lid must always be kept closed, and it is to be opened only to load theadhesive so that no foreign bodies or objects get into the tank.

The compressed air gives the Central Unit the hydraulic pressure needed foroperation. This compressed air is controlled by means of a regulator located on thebottom part of the front of the Central Unit.

The Central Units allow the pneumatic pressure values to be regulatedbetween 0 and 6 kg/cm2, according to the specific needs of the application.

IV. 3

WARNING The Central Unit Applicator runs at high temperatures.

The incorrect use or manipulation of this unitmay cause serious burns.

Introduction

Loading adhesive into theCentral Unit

Applicator

Flow rate regulation Depending on needs, the adhesive flow rate is regulated by means of severalcomponents:

1.- The temperature of the adhesive, which necessarily has to be within the limitsrecommended by the manufacturer.

2.- The pneumatic pressure, controlled by means of a regulator located on thefront panel of the Central Unit.

3.- The diameter of the diffusion for the outlet nozzle.

4.- The adhesive's viscosity, depending on the user's technical requirements.

With the same viscosity, the adhesive flow rate is directly proportional to thetemperature, the pneumatic pressure, and the diffusion diameter of the nozzle.

Practical advice to the user

• Do not go over the temperature recommended by the adhesive manufacturer.

• When the Central Unit is not going to be used for several hours, activating the Standby or disconnecting it is recommended.
