Structure

The T.VIS® M-20 is equipped with reliable and robust control electronics, containing the proven path measurement system of the T.VIS® A-15 as an on-board version. The cable connection to the central control level is implemented by the customer, either via externally accessible M12 plugs or via direct wiring to internal spring-loaded terminals, depending on the requirements. Parameters can be preset via DIP switches so that the actual commissioning no longer requires any further operation or configuration. Using an internal reset button, the electronics can be reset to delivery status after a valve service, so that a new self-learning process takes place automatically when the system is restarted. The supply air connection is equipped with a replaceable filter to protect the built-in solenoid valves.

Settings

Parameters such as tolerances, color switching or air support can be set using integrated DIP switches. The actual initialization process runs automatically. The procedure only requires closed connections between the control top and the air supply and electrical equipment. No other tools are necessary.

Logic NOT Function

Optionally, a logic NOT-function can be integrated into the control top without additional control effort. This provides automatic air support for the spring chamber to increase the closing force of the valve.
