MELTER OPERATION
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
connections are correctly established.
It is also necessary to make sure that the equipment has been filled with
adhesive 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
‘Temperature OK’.
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
temperature -3° in under 5 minutes, the unit will pass to ‘Temperature
OK’ status without taking the ‘Pumping Permission Delay’ into account.
3. Use the machine’s pressure gauge to make sure that the generated
pressure is adequate. Values below 0.5 bar may cause erratic pump
action.
