3 General information
3.1
AS-Interface in general
The ThinkTop is designed to ensure optimum valve control in conjunction with Alfa Laval sanitary valves and it is compatible
with all major PLC systems (Programmable Logic Controller with AS-interface).
The ThinkTop can be equipped with 0-3 solenoid valves. The solenoids are electrically controlled by the AS-Interface and
when activated the compressed air is activating the air actuator. All solenoids have build-in throttle function on both air inlet
and outlet which means that it is possible to control the opening and closing time of the air actuator. The solenoids are also
equipped with a manual hold override.
Visual LED lights are constantly indicating the status of the unit: Valve positions, solenoid energized, setup and local fault
indication etc.
The ThinkTop is characterized by a simple and modular design. It is exchangeable and is prepared for upgrading.
