Pressure sensor
Available only with options Pressure display and Pressure control.
ATTENTION: System and adhesive pressurized. Relieve system pressure.
Failure to observe can result in serious burns.
Cleaning Adhesive Bore
CAUTION: If the adhesive bore is to be cleaned with a sharp object, first
remove the pressure sensor to prevent damage to the separating membrane.
Cleaning Separating Membrane
ATTENTION: Hot! Risk of burns. Wear appropriate protective
clothing/equipment.
CAUTION: Use extreme caution when cleaning the separating membrane
(arrow, Fig. 5‐18). Never use hard tools.
Whenever possible, remove material residue only with a cleaning agent
recommended by the material supplier. Thermoplastic substances such as
hot melt adhesive may need to be heated with a hot air fan and then carefully
wiped off with a soft cloth.
Screwing in
Apply high temperature grease to the thread (Refer to Processing
Materials ).
Only screw into a very clean bore.
The melter part and the pressure sensor should be at room temperature
or at nearly the same temperature before the pressure sensor is screwed
in firmly.
Do not jam when screwing in (Strong resistance should not be felt).
Refer to Fig. 5‐19: Top illustration wrong; bottom correct: The screw plug
(2) is used as a guide for the separating membrane (1).
