In the central unit, the data acquired by the vacuum sensor and the light barrier unit is processed by the vacuum testing software and the control signals are calculated for the ejector. A touch screen with a colour graphics display, multilingual user interface and membrane keypad is provided for data entry and display. The recipe parameters for the containers to be tested are generated and saved via programme routines (teach-in).
The central unit is equipped with a main switch. 1 ½“ clamps are provided for mounting on the stand.
