SAFETY GUIDELINES
Mechanical components
The hot-melt installation, which is installed to this device, requires moving
parts that can cause damage. Use the equipment correctly, and do not remove
the safety guards while the equipment is in operation; prevent the risk of
possible entrapment due to moving mechanical parts.
Do not use the equipment if the safety devices are not in place or appear to be
inadequately installed.
For maintenance or repair operations, stop the movement of moveable parts
by turning off the main switch.
The device has no moving mechanical parts, so it does not pose risks to
consider in this section.
Electrical components
The system works with single-phase or three-phase current of a certain
power. Never handle the equipment with the power connected, as this may
result in powerful electrical shocks.
The installation must be correctly grounded.
The installation’s power cable conductors must match the required electric
current and voltage.
Periodically inspect the cables to check for crushing, wear and tear, as well as
to prevent tripping and falls as a result of their placement.
Although the system meets EMC requirements, it is inadvisable to use
devices that transmit high levels of radiation, i.e., mobile phones or soldering
equipment in their vecinity.
Hydraulic components
As this is a pressurized system, precautions related to this type of equipment
must be observed.
Before each operation, always make sure that the adhesive circuit is
completely free of pressure. There is a high risk of hot particle projection,
along with the corresponding danger of burns.
Use caution with the residual pressure that may remain in the hoses when the
adhesive cools. When reheated, there is a risk of hot particle projection if the
outputs are left open.
Pneumatic components
Some equipment uses compressed air to 6 bar pressure. Before any
manipulation, please ensure that the circuit has lost fully air pressure. The
risk of projection of particles at high speed can cause injury to a certain
severity.
Extreme precautions with the residual pressure that could be contained in the
circuit, before disconnecting any pneumatic feeding tube.

SAFETY GUIDELINES
1-3
MA-5168-ENG ADHESIVE MELTER CANTHO
Thermal components
The entire system works with temperatures that can exceed 200°C (392°F).
The equipment must be operated using adequate protection (clothing,
footwear, gloves and protective glasses) that completely cover exposed parts
of the body.
Keep in mind that, due to the high temperatures reached, the heat does not
dissipate immediately, even when the power (in this case, electric) source is
disconnected. Therefore, use caution, even with the adhesive itself. It may
remain very hot, even in a solid state.
In case of burns:
1. If the burn is the result of contact with melted adhesive, do not try to
remove the adhesive material from the skin. Do not try to remove it once
it has solidified either.
2. Cool the affected area down immediately with lots of cold and clean water.
3. Seek medical attention as soon as possible either from the company’s
medical service or the nearest hospital. Provide the medical staff with the
Safety Information Sheet of the adhesive.
Materials
Meler systems are designed for use with hot-melt adhesives. They should
not be used with any other type of material, and especially not with solvents,
which may cause personal injury or damage to internal system components.
Some units are specifically designed to use polyurethane reactive (PUR) hot-
melt adhesives. Using PUR on a unit that is not prepared for that purpose may
cause severe damage to the unit.
When using adhesive, follow the corresponding guidelines found in the
Technical and Safety Sheets provided by the manufacturer. Pay special
attention to the advised work temperatures in order to prevent adhesive
burning and degradation.
Ventilate the work area adequately in order to remove the vapors produced.
Avoid the prolonged inhalation of these vapors.
Always use original Meler components and replacement parts, which
guarantee the correct system operation and service.
Noise emission declaration
The A-weighted emission sound pressure level (LpA) of the unit in operation
does not exceed 70 dB(A) under any circumstances.
The maximum C-weighted sound pressure level (LpCpeak) and the A-weighted
sound power level (LWA) do not exceed values worthy of mention and thus do
not represent a specific risk that must be taken into account.

MA-5168-ENG ADHESIVE MELTER CANTHO
2. INTRODUCTION
This manual contains information on installing, using and maintaining the
Cantho adhesive melter from Focke Meler.
This unit is designed to melt PUR adhesive blocks (with or without a protective
bag) of 2-2.5 kilos, Ø130 mm and a height of 165 mm or EVA/APAO-based
pellets.
It is designed primarily for use in the wood market for rollers to edge planks.
Providing high efficiency and cost savings, high-performance and versatility,
simplicity and reduced maintenance costs, it is the ideal melter for fast
adhesive or colour changes.
Careful treatment of the adhesive (optimal) to prevent residues, carbonization
or deterioration.
Reduced dimensions for easy renovation in the machine or new installation.
In automatic mode, every time the roller coater tank sensor (located beneath
the melter) detects a low level of adhesive, it sends a signal to activate the
outlet valve, pusher plunger and the adhesive melter.
When the sensor detects the correct level once again, the adhesive transfer
stops and waits for the next signal. An alarm system warns of possible faults
in the repositioning of the adhesive block.

INTRODUCTION
Description
Operating modes
These melters can be used in the modes described below:
Operating mode_The melter keeps the hot components at the
temperature indicated on the display, which has been preselected as the
desired value. The system continues to wait for the signal to start the
piston pressure and to open the discharge valve to the unit’s roller tank.
1. Work mode with piston cylinder
Manual mode_It does not depend on the low level signal from
the roller tank sensor. The discharge process will be carried
out providing that this operating mode is selected with the
corresponding switch (MAN position) and providing that the
piston has been activated using the corresponding selector
(down), with the discharge valve being activated at the same
time. The discharge process will stop if the operating mode
switch is placed in position ‘0’ or the piston switch is placed in
the ‘0’ or ‘up’ position.
Automatic mode_If a low level is detected in the roller tank, the
piston and the discharge valve will be lowered and will remain
in this status until the level of adhesive detected by the sensor
is reached. At this point, the signal to lower the piston will be
deactivated and the discharge valve will close. This cycle will
repeat until the piston switch is moved to the ‘0’ or ‘up’ position,
or you exit automatic mode by placing the operating mode switch
in the ‘0’ position.
2. Work mode without piston cylinder
Manual mode_It does not depend on the low level signal from
the roller tank sensor. The discharge process will be carried
out providing that this operating mode is selected with the
corresponding switch (MAN position) , with the discharge valve
being activated at the same time. The discharge process will
stop if the operating mode switch is placed in position ‘0’.
Standby modes_The melter remains in standby mode with the
temperatures of the components at a (programmable) value that is
below the preselected value.
Warning/alarm mode_The melter detects a malfunction and alerts the
operator. According to the type of issue, the system will either continue
to operate or will stop until the incident has been resolved.
Stop mode_The melter remains off without heating the components.
However, the unit is still supplied with electrical power and
pneumatic air.
Hot-melt melter/applicator identification
When placing orders for replacement parts or requesting help from our
service center, you should know the model and reference number of your hot-
melt melter/applicator.
This and other technical information will be found on the identification plate
located on the side of the lower part of the hot-melt melter/applicator.

MA-5168-ENG ADHESIVE MELTER CANTHO
Unpacking
Before proceeding with the installation of the melter/applicator, it should be
removed from its location on a pallet and examined in order to detect any
possible breakage or deterioration. Communicate any defect, even to the outer
packing materials, to your ‘meler’ Representative or to the Main Office.
Contents
The ‘Cantho’ packing materials may contain accessories that form part of the
same order. If this is not the case, the following are the standard components
that accompany the melter/applicator:
• Instruction manual
• Guarantee card
Mounting the unit
The unit is fixed to the machine on top of the tank or the roller coater tray
using four M8 screws, together with the specific support for this.
Check that the discharge nozzle is positioned correctly and that nothing obs-
tructs the adhesive outflow.
Connecting the electrical panel
All of the unit’s internal control signals connect to the panel via the 24-pin
Harting connector. For direct connection to the user’s panel, consult the pin
layout on the unit’s electrical diagram.
Only the external signal of the roller tank level sensor should be connected
inside the panel to the terminals enabled for this purpose.
It can be a PNP or NPN signal, or a contact signal (normally closed or open,
programmable from the LOGO device).
If the level sensor is PNP or NPN, the positive signal will connect to the XLD2
terminal and the negative signal to the XLD3 terminal:

CONTACTO
PNP/NPN
24 VDC
XLD 41 2 3

FOCKE MELER GLUING SOLUTIONS INSTALATION
3-4
- In the case of a PNP sensor, the signal connects to the XLD2 terminal
and the 0 V to the XLD3 terminal.
- In the case of an NPN sensor, the signal connects to the XLD3 terminal
and the +24 V to the XLD2 terminal.
- In the case of a contact sensor, it connects to terminals XLD1 and XLD2
and a bridge must also be implemented between terminals XLD3 and
XLD4.
Electrical Consumption
In order to install a melter equipment os this serie, we should take into consi-
deration the total consumption of the installation,(see characteristics plate).
Before connecting, make sure that the voltage that is being connected to
the melter/applicator is the correct one appearing on the equipment’s
characteristics plate.
Connect the machine and check to see if it is well grounded.
Warning: Risk of electrocution. Even when the equipment is turned off,
voltage remains in the intake terminals, which may be dangerous during
internal equipment manipulations.
Install a power switch for disconnecting the melter/applicator equipment from
the electrical network. It must be protected against overload and short circuits
by circuit breaker and install appropriate personal protection leads to mass by
differential switch.
Compressed air
To install ‘Cantho’ series melters/applicators, it is necessary to have a dry,
non-lubricated compressed air system with a maximum pressure of 6 bar.
Other factors
While installing these melters, other practical considerations should be kept
in mind:
• Keep the load opening accessible for comfortable melter filling.
• Position the melter equipment in such a way that you can easily see the
front panel display where temperatures and possible alarm signals are
shown.
• Do not install the melter equipment beside powerful heat or cooling
sources that may have distortional effects upon its operation.
• Avoid melter vibrations.
• Make sure that the melter maintenance areas (filter, purging valve,
tank interior, etc.) are easily accessible.
