MELTER OPERATION
4-3
MA-5079-ENG MICRON GEAR ADHESIVE MELTER
If the control card was on the last time that the machine was disconnected, it
will turn on when the machine is started up again.
2. Press the ON/OFF button on the control card to turn it on, if it not
already activated.
By default, the set point and real temperature values shown are those
corresponding to the tank.
The tank heating control LED (green) will light up and the tank will begin to
heat.
One it has reached 3° below the programmed temperature (set point) of
the tank, a programmable delay timer starts until, guaranteeing fusion, the
pump receives permission to operate and the signal will be sent to the main
machine, indicated by the two corresponding (green) LEDs.
While the system is running the delay timer both LEDs remains blinking until
the programmed time value has been reached. If then, any other element has
not reached 3° below its temperature setting point, the LEDs turn off.
If the system is shut down, for any possible mode, when it is turning on the
delay timer only starts again if the tank temperature is 20° below setting
point.
3. Make sure that the selectors in the pumping control card for each
of the motors installed is in the correct position (see Chapter ‘2.
Introduction. Operating modes’).
Melter equipment displays
Micron series melters have two displays built into their control panel, with three
sets of 7 segments each for displaying the temperature values (set point and
real temperature), programmable parameters and alarms.
They are equipped with LED indicators to display the heating of each
component, as well as the pump activations and the main machine connection
signal:
They are also equipped with LEDs indicating equipment connection/
disconnection and standby function connection/disconnection:
LED display Component heating Component status
constantly lit constant low temperature
blinking slowly
as need (according to PID
parameters)
temperature near set point
blinking rapidly programming or display change in set point values
off not heating temperature reached
