T.VIS® M-20 Control Top

Common features of all T.VIS® variants are:

Flexible system for optimum variant configuration for the particular task
Internal air supply for high security against failure of the main valve functions because no external air hose is required
Characteristic design
High protection class (IP65/66, IP67 or IP69k)
Ease of cleaning without dead zones, whatever the installation orientation
Clear visualization of the valve status via a light dome visible 360°, which is illuminated by colored LEDs
Low energy consumption
Ease of handling
Maintenance-free electronic modules
Many special options, e.g.: Air throttles, Cable connections, etc.

For maintenance work on the valve, the control tops can be removed from the valve actuator by loosening two bolts on the clamp, without electrical or pneumatic connections having to be disconnected.

Features

Proven housing technology
The highest protection class as standard
High vibration and shock resistance
Individual connection technology
Self-learning initialization
Extremely easy commissioning
Parameters can be preset
Standardized T.VIS® visualization with diagnostic function

Description

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.
