| 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. For unthrottled operation, the filling valve must be permanently electrically actuated. Actuating the electric priority circuit disrupts the slow pressure build-up and pressure p1 is immediately applied. 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. |
