Abstract

A monitoring system (10) monitors pressure in a pneumatic assembly (15) that supplies compressed air at a predetermined operating pressure (P1) from a pneumatic source (20) to at least one pneumatic load (100, 100 1 , 100 2 ,..., 100 n ) actuatable thereby. The monitoring system includes a pressure reducing device (25) that reduces the pressure of the compressed air to a lower, leakage test pressure (P2). A switching device (40) has a first switch position, in which the at least one pneumatic load is supplied with the compressed air at the leakage test pressure, and a second switch position, in which the at least one pneumatic load is supplied with compressed air at the operating pressure. A pressure sensor (50) continuously senses the pressure within a connecting piping (92-98) and outputs a warning signal in case the detected pressure falls below a predetermined threshold pressure (P3).
