Enables the user to operate the valve by push-buttons and gives access to the parametrization of smart linear and quarter turn actuators, without using a PC. Additionally, the valve position is shown in an illuminated display. By using a padlock, unauthorized use is prevented.

For intelligent linear actuators PS-AMS PSL up to 14 kN, the interface is installed instead of the cover of the terminal box. For intelligent quarter-turn actuators PS-AMS PSQ and intelligent linear actuators PSL320-325AMS, the interface is mounted on an external terminal box. For intelligent quarter-turn actuators PS-AMS PSQ-S the new generation of local control PSC.3 is mounted on an external terminal box.
