3.2. Advanced safety function for AlphaTack HS (High Speed)
The AlphaTack HS supports roller speeds up to 450 m/min. For protecting the operators
coming in any touch with these fast turning rollers the AlphaTack HS is equipped with
ultrasonic proximity switch for instant roller stop.
A periodic peep sounds as soon as there any object closer than 40 cm in front of the rollers.
In case the distance is shorten down to 30 cm the rollers and so also the test stop within one
second.
Washing is possible without any limitation since elastomer roller is separated from metal
roller.
