METHOD FOR OPERATING A CONTAINER TREATMENT SYSTEM WITH FAULT DIAGNOSIS

Method for operating a container treatment system (1), wherein containers are treated in a first predefined fashion with a first treatment device (2) of this container treatment system (1), are subsequently transported from this first treatment device (2) to a second treatment device (4) of the container treatment system (1) and are subsequently treated in a second predefined fashion by the second treatment device (4), wherein a first multiplicity of first reference characteristic values (RK1), which are characteristic of the treatment of the containers (10) the first treatment device (2), is recorded by means of first sensor devices (22a, 24a), and a second multiplicity of second reference characteristic values (RK2), which are characteristic of the treatment of the containers (10) with the second treatment device (4), is recorded by means of second sensor devices (42a, 44a), and wherein these reference characteristic values (RK1, RK2) are stored in a memory device (16). According to the invention, the reference characteristic values (RK1, RK2) are registered with a time value which is characteristic of the chronological occurrence of the respective reference characteristic value (RK1, RK2), and a multiplicity of test characteristic values (PK1, PK2) is recorded, and at least one information item (I), which is characteristic of the determination of a present or future fault state of the system, is output on the basis of comparison between at least one of these test characteristic values (PK1, PK2) and at least one reference characteristic value (RK1, RK2).
