Valve position indicators that tell more than just on or off

The 2040 digital position indicator uses a colored light signal, visible from a distance, to show the open or closed position of a valve. Four different color signals are used: open and closed by yellow and green. At the push of a button, these colored signals can represent the end stops. In addition, when the end stop is reached, the digital position indicator outputs this as a switching signal to the contacts on the connector plug. The position indicator also signals maintenance information and issues error messages, which can be: stuck valve, wear in seals, temperature outside the permissible range and supply voltage too low. — Schubert & Salzer Control Systems GmbH, Ingolstadt, Germany
