NOTE: The solenoid valves may only be triggered or activated when the
application head has been heated up! Failure to observe may cause
damage to the nozzle stem seals in the control modules.
The solenoid valves are operated by an electronic control unit that ensures
that the solenoid valves open and close at the right times.
The control module precisely opens and closes the adhesive supply to the
nozzle by pneumatically raising or lowering the nozzle stem. A compression
spring ensures that the application nozzle is closed when pressure drops,
preventing adhesive from being applied.
The application head is heated with electrical heater cartridges. The
temperature is continuously measured by temperature sensors and is
controlled with electronic temperature controllers.
Temperature controllers are not part of the application head.
The ID plate displays the following information:
