Abstract
A compressed air conditioning apparatus (2) and a load control device (1) equipped therewith are proposed, the compressed air conditioning apparatus (2) comprising a switch-on valve (14) with 3/3-valve functionality. By means of the switch-on valve (14), an outlet passage (22) leading to a load device (A) can, among other aspects, be optionally supplied with compressed air or disconnected from the compressed air supply. By means of a pressure sensor (24) and/or a flow sensor (25), actual pressure and/or flow data can be recorded and compared to reference data previously stored in a teaching mode. As a function of the comparison result, an electric diagnostic signal can be generated, offering, among other aspects, the opportunity for monitoring leakage from the load device (A) or excessive air consumption.
