MELTER OPERATION
4-19
MA-5184-ENG PUR LC/MC ADHESIVE MELTER
Operating mode with external pumping control and external speed control
In this operating mode, both pumping and speed are controlled externally
from the main machine.
The ‘External reference’ and ‘External permission’ options must be activated.
Follow the steps below to use this operating mode:
1. On the start screen, press the pump status icon to access the Pumping
Control menu.
2. The status of the external permission is shown on the Pumping Control
menu. When the LED is green, the contact is closed and the pump can
be started up; when it is red, the contact is open and the pump will
remain off.
The following conditions must be met for the pump to start operating:
• The unit must be at ‘Temperature OK’.
• The ‘Pumping permission delay’ time must have elapsed.
• If ‘Pumping safety’ is activated, pumping must be enabled with the
‘STOP’ button (red LED off).
• There must be no alarms preventing pumping.
The system will wait for the speed signal from the main machine.
When this is received, the pump will start rotating at the set speed. The
actual rotation speed is shown on the display.
3. To set the rotation speed to the necessary value for the application,
change the ramp speed (see the ‘Configuring ramp speed’ section).
Together with the ramp speed graph, the display shows the voltage
being delivered from the main machine at that moment.
The pump will stop whenever:
• The control board is disabled using the ON/OFF button.
• The pumping ‘STOP’ button is pressed (red LED is lit).
• When a variator error signal is activated.
• When the MAXIMUM RPM alarm is activated.
• When the MINIMUM RPM alarm is activated.
4. If the unit has a rear switch connector (optional), pumping can also
be activated from the device associated with this connector. Both the
‘External permission’ and switch must be connected to allow the pump
to be activated.
When the LED is green, the contact is closed and the pump can be
started up; when it is red, the contact is open and the pump will remain
off.
