| The pressure dew point must be at least 15 °C under ambient and medium temperature and may not exceed 3 °C . A change in the flow direction (from air supply on the left to air supply on the right) occurs by rotating installation by 180° about the vertical axis. Please see the operating instructions for further details. The filling valve builds up pressure slowly in the pneumatic systems, i.e. prevents a sudden pressure build-up during a recommissioning after a mains pressure failure or avoids emergency OFF switching. This allows dangerous abrupt cylinder motions to be avoided. Actuating the electric priority circuit disrupts the slow pressure build-up and pressure p1 is immediately applied. For unthrottled operation, the filling valve must be permanently electrically actuated. |
