4.4 Automatic temperature reduction system ACE (AntiCharElectronic)
To protect the hot melt adhesive from unnecessarily high temperature the operating temperature is automatically reduced by 104°F /
40 °C to a stand-by level if the applicator is not used for approx. 30 minutes.
The right decimal dot of the digital display (5) flashes.
Squeeze the trigger (15) or push the UP and DOWN buttons (9/8) to heat up to operating temperature.
4.5 Interruption of work / End of shift
Press the start/stop-button (6) to switch off the temperature controller.
Reduce with the pressure regulator (3) the operating pressure to “0" or turn off the compressed air supply.
4.6 Troubleshooting and remedying faults
In the event of malfunctions first check the compressed air and power supply.
In the event of a fault in the heating system a safety temperature controller prevents the applicator from heating up over 500 °F (± 11
°C).
5. Maintenance / Servicing
Servicing and maintenance work, which afford the opening of the housing, may only performed by competent electrician personell.
Before servicing or performing any maintenance work always turn off the compressed air supply and powersupply. Wearing personal
safety equipment (heat protection gloves, protective goggles) increases safety.
Before servicing or performing maintenance work on components which come into contact with hot melt adhesive they must be heated
up beforehand (heat up the applicator or use an external hot-air gun).
