7.12 DrainType ObjectType Definition ToC Previous Next

The DrainType is the representation of a condensate drain and extends its supertype by specific Nodes. Derived from EN 1012-1/ISO/DIS 18623-1, a condensate drain minimizes the accumulation of stagnant liquid in a Compressed Air System. It is illustrated in Figure 25 and formally defined in Table 31.

When instantiating this ObjectType the Identification Object shall use one of the concrete subtypes of the MachineryItemIdentificationType, either MachineIdentificationType or MachineryComponentIdentificationType, depending on the concrete usage of this Component. The ModellingRule of the Property DeviceClass remains as mandatory and its Value Attribute shall match the value stated in Table 9.

The InstanceDeclarations of the DrainType have additional Attributes defined in Table 32.
