Apex Slot Die Applicator, Manual #40-47, Rev. 10.16
Risk of stumbling on cables and heated hoses!
Keep your hands away from running parts of the unit (pumps, motors, rolls
or others).
4.5 Setting-up operation, in general
This is a generic start-up and purging process:
1. Check the complete unit and the traverse paths for safety. Fix visible damages
immediately.
2. Before switching the unit on, make sure that the starting unit could hurt no one!
3. Remove all material or other things not needed for the production from the workspace
of the unit!
4. To turn the main power on, turn all main switches of the components to "ON"!
5. Set the temperatures in the controller.
Heed following advices:
•
The operating temperature range is 38°C to 200°C (100°F to 390°F)
•
Use only adhesives recommended by the adhesive manufacturer! Before changing
from one type of adhesive to another (even within the same product line of one
manufacturer), the unit has to be cleaned respectively purged to avoid possible
chemical reactions.
•
Set the temperatures of the particular heating zones in the controller according to the
adhesive that is in use. Always keep the temperature range given by the adhesive
manufacturer. Wrong temperature settings could cause the burning of the adhesive
within the system and unsatisfactory adhesion.
•
Before starting the production, keep the required heat-up phase of the adhesive
respectively of the Melter, so that sufficient adhesive can be molten and supplied to
the applicator.
CAUTION
The unit is ready for operation, when
•
all temperatures are within the tolerances,
•
the adhesive in the tank of Melter is molten completely.
Switch on the motors/pumps only if the adhesive is completely molten!
Untimely start of the motors could cause the following risks:
•
The pumps are not sufficiently supplied with adhesive and they intake air. The air
causes foam formation within the adhesive system and reactions with PUR adhesives.
•
The pumps run dry and may block.
•
Solid adhesive could block the intake port. The pumps and motors may overheat and
even be destroyed.
