MELTER OPERATION
Filling the tank
The tank can be equipped with a low level sensor (optional) that warns when
the adhesive reaches the programmed level.
The unit will activate the external signal and, if it is connected, the
corresponding warning device.
Warning : Before refilling the tank, make sure that the adhesive is the same
type as that already in the tank. Mixing different types of adhesives can cause
damage to the melter equipment.
To fill the tank:
1. Open the outer lid and the air-tight tank lid.
2. Fill the tank with adhesive block of 2-2.5 kg in case of Micron PUR LC
and adhesive block of 20 kg in case of Micron PUR MC.
3. Open the adhesive block and insert it into the cylindrical tank.
4. Close the air-tight lid and the outer lid when you have finished refilling
the tank.
Warning : Risk of burns. Always refill using protective gloves and goggles.
Starting up the melter equipment
Before starting up the melter equipment, it is necessary to check to see if the
unit has been correctly installed and all its input/output and accessory con-
nections are correctly established.
It is also necessary to make sure that the equipment has been filled with ad-
hesive and that the operational parameters have been programmed.
To start:
1. Connect the melter’s switch.
When the switch is actuated, the GREEN POWER LED remains lit. The unit
is powered but the screen stays off.
2. When you press the ON/OFF button, the screen lights up and the POWER
LED stays lit. The main screen shows the unit’s status.
One it has reached 3° below the programmed temperature (set point)
of the all active elements, a programmable delay timer starts until,
guaranteeing fusion, the pump receives permission to operate and the
signal will be sent to the main machine by the external output ‘READY’.
While the system counts down the delay time, the temperature OK
symbol flashes until the programmed time value is reached. The
screen displays the actual temperature values for each zone at all
times.
If the temperatures of all the active zones exceed the set point tempe-
rature -3° in under 5 minutes, the unit will pass to ‘Temperature OK’
status without taking the ‘Pumping Permission Delay’ into account.
