Abstract: A method for detecting output-side leaks in a double cone air power booster is proposed. Initially, a reference curve is recorded which relates a control variable for the outlet pressure to the outlet pressure. During operation, at least one steady state is determined, wherein only steady states preceded by a drop in the output pressure of the double cone air power booster are considered. Values of the control variable and the output pressure belonging to the steady state are determined and compared with the reference curve. If the output pressure determined is smaller by a specified tolerance than the output pressure to be expected according to the reference curve for the control variable determined, an output-side leakage is determined. In this way, leaks in the consumer system connected to a double-cone air power booster, for example a pneumatic control valve actuator, can be detected in an uncomplicated manner, which can save costs for maintenance requirements that are detected too late. Additional components are not required.

Abstract: In a method for diagnosing control system of a process engineering plant having a plurality of actuating units for setting a process fluid and a central unit, at least one actuating-unit-specific control raw datum, such as a setpoint value, an actual value, a setpoint-actual difference value, or a control value, is detected; a particularly local diagnosis code is generated by one of the plurality of actuating units based on the at least one detected control raw datum; the diagnosis code is transmitted from the actuating unit to a central unit; a local diagnosis code, is transformed into a global diagnosis codes; a logical condition for a diagnosis deduction logic is defined such that when the logical condition is applied to at least one diagnosis code, the diagnosis deduction logic determines a predetermined deduction result; and a deduction result is determined based on the at least one diagnosis code.
