Screwdrivers with supervision
Pneumatic Srewdrivers with additional function control.
The supevisor counts the number of screws per part, checks for torque shut off as well as the time to assemble each screw (thereby checking for loose, stripped or cross threaded screws).
If an error occurs, the controller fc20 locks-out the connected Screwdriver. The subsequent assembly process can only be started if the previous task was completed properly. The correct number of tightened screws per assembly can also be controlled.
