ELECTRIC FEATURES
All the electric connections, (for power and signals), are
realized with the suitable connectors in compliance with the
standards so that only the correct connector couples with
its correspondent by eliminating in advance the possibility
to carry out wrong connections.
2.5
PNEUMATIC FEATURES
All the consoles are equipped with pneumatic double
effect piston pump with a compression ratio of 13:1. The
advantage of the pump with double effect (housed in the
rear part of the tank and heated by means of the contact
of the glue), consists that its working assures a constant
glue flow inside the hoses, a fundamental factor in each
application. The pneumatic plant has been realized with the
aim to facilitate each Customer’s need.
2.6
MACHINE COMPONENTS
PREO applicators are supplied with the following parts:
TANK
MANIFOLD
PNEUMATIC PUMP
ELECTRIC REVERSER
MICROPROCESSORS
GUNS
MODULES
THERMO HEATED HOSES
NOZZLES
As follows technical characteristics are represented:
TANK
The tank (with the capacity of 3,5 kg or 5 kg in order to
satisfy each exigency of production), constitutes the
principal core of a hot - melt system because inside it the
adhesive, in granules or pigs, that will be lead to the
melting temperature, is placed.
The parts in contact with the adhesive, are covered by
PTFE resisting to high temperatures.
This covering has a fundamental importance, because it
permits to avoid that the glue forms a film on the walls. It
is necessary that these are well-levelled and treated by
means of ant adhering and ant scratch material in order to
facilitate the skipping towards the lower part of the glue.
In fact at the application temperature the residual
transforms itself into a carbonised one, that would be very
dangerous for system working .
The bottom of the tank, with a double thickness than the
traditional tanks, permits a larger heat distribution.
The heating of the tank is performed in a gradual and
constant way thanks to the cylindrical resistances
 2002 PREO SRL – All rights reserved
PAGE 2
(replaceable) of great and proved reliability, that are
inserted in the bottom of the tank. Temperature survey
and check are guaranteed by means of probes with a very
high precision degree.
On the bottom of the tank the speed drainage of the
glue is obtained by means of an opening system placed on
the rear part.
MANIFOLD
On the rear part of the tank the manifold is situated,
obtained by an aluminium bloc.
It is possible to connect 4 hoses by means of threaded
unions. The fuse adhesive, is pushed by the pump into the
manifold and is distributed inside the hoses in order to
reach finally the guns.
For this reason the manifold has a great importance in a
hot - melt system, in fact upon its constructive precision
the good applicator system depends.
Inside the manifold the glue filter is placed, constructed
in stainless steel in a sole casing, with mesh cage of 100
mesh ( 0,15 mm).
PNEUMATIC PUMP
All PREO consoles are equipped with pneumatic piston
pump with double effect with a compression ratio of 13:1.
The advantage of the double effect pump (cased on the
tank and heated for the contact of the glue), consists that
its working assures a constant glue flow, by avoiding the
typical single effect pump pulsations.
ELECTRIC REVERSER
The pump exchange between lifting and lowering is
carried out by an electric inverter operated by the same
pump.
MICROPROCESSORS
Microprocessors keep the complete checking of all the
operations of the machine for what concerns the
thermoregulation of the glue inside the various parts of the
console, and for what concerns the distribution of the glue
on 2 or 4 channels completely independent.
The microprocessor programming results facilitated and
of immediate receipt thanks to the revolutionary keyboard

one part concerning value setting and one part concerning
the distribution of the glue lines (depending upon the
computer).
Common and important characteristics of PREO
microprocessor are:
Sequential heating of the various channels: on
switching on the plant, the tank, which forms the
greater volume of glue to melt, is the first to reach the
working temperature, followed by hoses and guns at
50° C . The advantage is that system components
reach the temperature at the same time by saving
energy and obtaining a better conservation of the hot melt.
Pump start to avoid pump submitting to the work
pressure before that the glue is not completely melted,
on the pneumatic circuit a solenoid valve is placed, this
is managed by the microprocessor which enables the
pump 5° C before reaching the set - point. A further
safety is given by the automatic disconnection by
means of the solenoid valve microprocessor, when tank
temperature comes out from the alarm band that is
fixed by a value range that is between -10°C and +8°
C on the ground of the set - point, by causing glue

USE AND MAINTENANCE MANUAL
distribution interruption and by turning on the red
warning light.
Anomaly signalling : in the case of interruption of
the survey temperature probe of any component, or of
the probe in short circuit, proper anomaly-signalling
messages are displayed in order to facilitate fault
localization .
Economy function: temperature lowering to a value
that is set up in a way to keep the glue fluid but not at
the operating temperature.
Clock and Weekly Programming : automatic
turning on and off on the ground of the programming
inserted in the microprocessor.
Check Display Function : permits an immediate
working checking of all the led display segments and of
the indication led.
Maximum absolute temperature alarm : if the
temperature taken from any channel exceeds the
threshold value (230°C) for more than 15 seconds, the
thermoregulation on all the channels disconnects
automatically. A further safety is assured by the
thermal fuse that has the task to lock the machine
whenever the tank temperature exceeds 228 °C.
Double size display opposite to the normal for an
easy reading, modification and even a remote checking
of the set up values.

GUNS
For standard execution and for high temperatures PREO
Hot - Melt adhesive guns have been designed and studied
with different configurations in order to satisfy the most
various Customer requests for particular applications.
Classic standard guns with one module, those special ones
with two modules with different axle bases and nozzles,
the ones with tighten profile or those with depressed
profile and finally those with one or two solenoid valves are
available. Their heating is obtained by means of highreliability resistance and it is checked by high precision
sensors. The presence of one stainless steel filter with
meshes with 100 mesh that can be extracted without hose
disassembling, guarantees the total impurity lack during
glue delivery by increasing the already known great
reliability of PREO guns.
PREO gun characteristics are:

The complete PREO gun range includes :
Long Life Series : in both standard and high
temperature execution they are available in different
models (with one or more different distances and
nozzles, with one or two solenoids), in order to meet
any specific application needs. Highly reliable spray
guns, used in different applications with maximum
operation speed of 4000 cycles per minute, with
interchangeable cartridge and standard self-cleaning
zero cavity nozzles. Possibility of using 90° nozzle or
multi tracks, swivel nozzle and coating heads,
according to your needs. The spray guns are
manufactured without outer guard and are provided
with a protective, non-stick coating on the gun body
where the electric wiring is inserted for the best safety.
EDITION 07/2002
USE AND MAINTENANCE MANUAL
Thanks to an advanced way of manufacture, the
heating is evenly distributed on the whole surface. The
heating is produced by the most reliable electric
elements and controlled by very accurate sensors.
They are complete with a stainless steel filter which
can be removed without disturbing the hose and which
prevents dust from entering the gun during glue
supply stages.
Low Profile Series : similar to the Long Life series,
they can be provided with 2 or 4 modules with a 90°
nozzle and are used for applications of particular size.
As a matter of fact, thanks to their very low profile,
they can be positioned between the cardboard flaps
during the closing operations.
Slim Series : similar to the Long Life series, they can
be equipped with self-cleaning zero cavity long nozzles
up to 65 mm which can distribute glue even in very
narrow or deep points. These new nozzles are made of
special alloy mostly used in the aerospace sector, from
which PREO has gain its experience for years. The
material employed has a thermal conductivity 8 times
higher than a normal brass alloy maintaining a
constant temperature along the length of the nozzle.
They are mostly suitable in the food, ceramics and
bookbinding industry field.
Spray and Spyro Series : similar to the Long Life
series, they are employed for gluing large surfaces
where a low glue weight is required. they have a new
heating block inside which keeps a constant
temperature of the air used for the product spraying,
thus ensuring precise and reliable results. the Spray
version is used for an even spraying of the product,
while the Spyro series allows you to obtain spiralshaped glue strips.
New Life Series: they are the most compact and
fastest spray guns of the series. They are mechanically
similar to the Long Life series, but they are
characterised by a small size and a fast application (up
to 6500 cycles per minute). Their standard
configuration provides the New Life module (with seal
cartridge system), and a self-cleaning zero cavity
nozzle for the best application. Moreover, the gun body
is provided with a protective non stick coating where
the electric wiring and the glue filter are situated for
maximum safety (the filter can be removed without
disturbing the hose).
Revolution Series : they provide the best solution
for each gluing problem thanks to their small size and
versatility, and can replace the common multimodule
spray guns with fixed spray centres distances. They
are provided with self-cleaning zero cavity nozzles, 2 or
more modules custom engineered centre distances
and independent control for each module. The distance
between the modules can be changed simply by
rotating them, so that you can use only one spray gun
for various applications, thus ensuring a high flexibility
and saving of time, maintenance, spare parts and
stoppages.
MODULES
Fundamental part in the system is available in different
configurations :
Long Life Series : it’s
the first module with
interchangeable seal cartridge which ensures the
highest quality and reliability. Thanks to our experience
in the aerospace and aeronautical industry, Preo S.r.l.
has applied these modules to the whole system, thus
 2002 PREO SRL – All rights reserved
PAGE 4
improving the efficient performances and the fast, easy
maintenance. The precision and reliability of the glue
application system depends on this module which is
therefore carefully designed and manufactured. Long
life modules are equipped internally with a purpose
designed and innovative seal cartridge which ensures
perfect sealing at high pressures and temperatures
giving an economical, easy virtually maintenance free
working life. To replace the cartridge, one has only to
unscrew the seal cartridge from the module body, and
screw in a new cartridge in order to have a perfectly
working module without affecting the reliability and the
high-quality of the system. The main technical
characteristics are:
♦ brass module body
♦ special Teflon coating and external coating of facehardening
♦ needle made of a hard-metal with a titanium coating
♦ flow equalizer to ensure even control air for needle
operation
♦ easy module replacement
♦ possibility to change the zero-cavity module into a
traditional one by means of an adapter
♦ high velocity
♦ precise application.
Moreover, the new “COVER CLACK ”protection guard is
also available! It is a useful and user-friendly means to
keep the module clean and protected.
These characteristics and the constant technical
development make PREO’s LONG LIFE modules fit for
every application.
Coating Series : ideal for all hot melt coating
applications (continuous or interrupted strip with
different thickness and widths up to 100 mm). This
module is equipped with a purpose designed and
manufactured innovating seal cartridge that ensures
perfect tightness against operating pressure and an
economical, virtually maintenance-free working life.
New Life Series : with the same Long Life series
standard characteristics, this series has reduced
dimensions and reacts faster. They are also internally
equipped with a purpose designed and manufactured
innovating seal cartridge
that ensures perfect
tightness against operating pressure and an
economical, virtually maintenance-free working life.
New Age Series : Preo Srl has launched a worldwide
innovation in the field of hot melt application modules.
We have designed the smallest ever module with three
zero-cavity nozzles. The remarkable innovation is the
module width (38 mm), the distance between the
nozzles (11 mm), the possibility of controlling each
nozzle independently and the versatility of the product
which can be assembled separately or in series. It is
characterized by a seal cartridge system and it satisfies
the requirements of a perfect and safe sealing.
THERMO HEATED HOSES
These are available with different standard and special
configurations, and include the following models.
NOZZLES
Available in different standard and special configurations,
include the following models :
Zero Cavity Nozzles series ZC / KV and ZC / LV:
manufactured in stainless steel, they equip the
standard modules. They have the possibility of holes
EDITION 07/2002
USE AND MAINTENANCE MANUAL
with a minimum diameter of 0,3 mm until a maximum
of 1,2 mm. They are defined Zero Cavity because the
shutter closes directly the nozzle hole by crumbling
possible impurities and by warranting a continuous
cleaning of the same nozzle and the consequent good
system operation.
Straight Nozzles at 90° series NDS and NDS – O:
manufactured in brass, are formed by threaded
terminal adaptor on which the straight nozzle (series
NDS) or the one at 90° (NDS - O) is screwed. As they
are available with different measures for each
application type, they are usually used when extreme
precision for glue flow adjustment is required.
Multivein Nozzles Series MVN with 1 - 2 - 3 - 4
tracks: are formed by a stainless steel threaded
terminal and a brass nozzle with 1 or more holes with
different angles. Even these ones are used where
guns with more modules are not utilized.
Coating Nozzles Series CH: constituted by a
stainless steel body that is supplied with a seal, they
are used where it is necessary to apply an adhesive
coat with the lowest thickness and large surface that
can not be obtained by traditional nozzles.

PUMP SIDE CLAMPING OPENING
The access to the rear and front part of the machine is
prevented by the use of a metallic coachwork which
protects the pump and avoids the casual insert of objects
or hands inside it. The protection presents holes in order to
permit a better heat disposal. To enter the pump, it is
necessary to have the special key which clamps the cover.
The special key of pump panel opening must be in
possession of the operator charged with machine

USE AND MAINTENANCE MANUAL
TANK TEMPERATURE SURVEY PROBE
The maximum temperature that can be set up is 255°C
independently from the type of adhesive used.
SAFETY BY - PASS
The safety by-pass presence, permits the release of
possible overpressure that are present in the circuit, as well
as the adhesive flow adjustment by keeping the air
pressure unalterated.
TEMPERATURE MONITORING MICROPROCESSOR
Working temperature (0°-255°C) is set up by the
keyboard and taken immediately by probes placed in the
tank. One of microprocessor special functions consists in
signalling on the display when the temperature exceeds of
8°C the temperature that has been set up as set-point.
Check the display in order to make sure of the
correct system working, in case of anomalies stop
the machine and consult the manual.
NOTE: errors or anomalies in the heating circuit are
signalled by the following messages on the display:
S co. (probe in short circuit). It indicates that the probe
is not able to «read» any more and therefore the heating
of the respective element is inhibited (tank, hose, gun).
S.in. (interrupted probe). It indicates that the element is
disconnected from the equipment and there is not any
heating.
Example: in a system with 2 hoses and 2 guns set up the
value of disconnected hoses and guns to 0 (zero). Without
this expedient, the system localizes the channel to which
any component is not connected, it compares it with the
respective set-up value of SET-POINT (where it takes a
value different from «0») and warns the operator that
channel 4 has an interrupted probe (as it were a damage)
by making the message S.in blink on TEMPERATURE
display.
READY AND STOP MACHINE WARNING LIGHTS
The machine is supplied with two warning lights that
signal machine proceeding: with switched-on warning light
the machine is ready to be used; with red warning light the
machine has found an anomaly or the glue has not reached
the set point temperature.
SAFETY HOSES FOR HIGH PRESSURE
The hydraulic connection between the console and the
gun is carried out by means of flexible hoses thermo
regulated at high pressure as the ones that are used by
aeronautics. The frame is formed by a Teflon hose with a
diameter of 8 mm and reinforced by a stainless steel plait
that resists at high pressure. Around it an electric heating
resistance, that is insulated in PTFE, screened and covered
by glass fibre band and equipped with a ground conductor,
is spiral shaped. In a correct position a probe is connected
for temperature survey. A thick silicone foam sheath
guarantees the perfect thermal insulation, while an
auxiliary polyester mesh covers the whole by increasing
heat resistance to shoves, and abrasions (see the following
drawing). The hoses are manufactured in order to resist to
temperatures until 110 bar and are in compliance to CE
standards in force; (the copy of conformity certificates is
kept in the machine technical booklet at PREO company).

SAFETY ELECTRIC CONNECTIONS
All the electric connections for the power and the signals
that are present on PREO machines are realized by means
of suitable connectors with a conformation that only the
proper connector can couple with its respective one by
eliminating in advance the possibility to carry out wrong
connections that damage the system. High-insulating
connections have been arranged where it is foreseen a
voltage passage at 380V, while for signal and service
connections, connectors with high capacity contact have
been chosen in order to avoid casual signal loss problems
because of a bad contact. External connections are
supplied with a covering plug in order to prevent the case
that they are not used and are in compliance with CE
STANDARDS.

Check the Economy status.
Check the fuses inside the machine.
Check that the set points have not been changed.
The microprocessor signals alarm and it places
on tank temperature and on temperature
display the message S.in is visualized.
Check the signal quality of tank probe (it must have a
resistive signal equal to 100 Ohm at room
temperature). If it is necessary, replace the pump.
The microprocessor signals alarm and it places
on the temperature relative to a hose or to a
gun and on temperature display the message
S.in is visualized.
Check that temperature data relative to a disconnected
component have not been inserted wrongly; in fact it
happened, it would be as the computer found an
interrupted probe, therefore : when temperatures are
programmed, it is necessary to set up the value
«ZERO» on all the disconnected outputs.
If, on checking point 1, everything is OK, check signal
quality of the probe relative to the component
indicated by the microprocessor. The probe must have
a resistive signal equal to 100 Ohm at room
temperature. If the signal is different, replace the
probe if guns are treated. For what concerns the
hoses, please apply to the technical assistance service
The computer gets in alarm and the channel
temperature falls from the programmed levels.
Check and in case replace the resistance. Check and in
case replace the fuses.
The microprocessor signals continuous sudden
changes of temperature of one component.
Check the connections and the respective probe signal
that must give a resistive load of 100 Ohm. If the
connections are OK, replace the probe because its
operation is not regular.
Adhesive excess at bead end?

PROBLEMS ABOUT THE ELECTRIC OR ELECTRONIC PART RELATIVE
TO THE PROGRAMME?
The programme starts without any evident
reason.
Check that no base machine component excites the
photocell too.
The programme is not more excited.
Check the control switch of 24V.
Check that the photocell is not intercepting some
foreign body.
Check that rays do not interfere with photocell reading
beam.
Check that the respective fuses are good.
Check gun - hose, hose - console and interface microprocessor connections.
Check the transformer.
Where the encoder is used, check that its signals
arrive correctly to the microprocessor, because the
signal lack for the computer means stopped machine
Check that the reset contact is correct, this means that
is open in order to permit programme starting.
The glue is applied on a box and not on the next
one.
The photocell reads the following box when the
programme is still operating on the previous one; it is
necessary to increase the distances between the boxes
or to approach the photocell to the nozzle line and to
programme again the microprocessor.

The glue line changes the size on the ground of
the speed.
Install the encoder, the proportional valve and
programme again the system in encoder.
♦
The glue line, even if it is in encoder and uses
the proportional valve, moves backwards on
changing of the speed that increases.
Programme the relative to automatic correction (see
the part relative to the microprocessor).

MACHINE STORING
If it is foreseen not to use the machine for a certain
period, it is advisable to :
♦
♦
♦
♦
Turn off the machine.
Disconnect ELECTRIC feeding.
Disconnect PNEUMATIC feeding..
Check with much attention that the pneumatic feeding
hoses have not been damaged or cracked, on the
contrary replace them.
Clean by means of a water jet all the parts on sight.
Empty and clean the tank with the method indicated in
section 5.
Pass with a film of oil all the parts subject to rust.
Cover the whole machine with a waterproof tarpaulin
Keep the machine in a dry place in order to preserve
all the electric parts. Room temperature must be
included between 25 °C and 40° C.

6.2
FINAL DEMOLITION
If you want, for any reason, to demolish the machine, it
is necessary to comply with some basic rules aiming at
safeguarding the environment. Sheaths, flexible tubes,
components made up of plastic or non-metallic materials,
must be disassembled and disposed of separately.
Hydraulic and electric components, such as valves, solenoid
valves, etc., must be disassemble in order to be used again
if they are in good conditions, or to be, if it is possible,
overhauled and recycled.
NOTE : the machine does not contain polluting oils.
