7.4.4.55.3 Properties

Name Property Type Data Type Description
AdjustmentValueType IfcPropertyEnumeratedValue PEnum_AdjustmentValueType

The type of adjustment value that is applied through the property set. This determines the properties that should be asserted (see below).

TimeAdjustmentRange IfcPropertyBoundedValue IfcTimeMeasure

Upper and lower time adjustment limits for an AdjustmentValueType = RANGE. Note that this property should not have a value for an AdjustmentValueType = LIST.

TimeAdjustmentRangeStepValue IfcPropertySingleValue IfcTimeMeasure

Step value of time adjustment for an AdjustmentValueType = RANGE. Note that this property should not have a value for an AdjustmentValueType = LIST.

TimeAdjustmentValues IfcPropertyListValue IfcTimeMeasure

A list of time adjustment values that may be applied to a tripping unit for an AdjustmentValueType = LIST. A minimum of 1 and a maximum of 16 adjustment values may be specified. Note that this property should not have a value for an AdjustmentValueType = RANGE.

AdjustmentDesignation IfcPropertySingleValue IfcLabel

The desgnation on the device for the adjustment.

CurrentForTimeDelay IfcPropertySingleValue IfcTimeMeasure

The tripping current in [x In] at which the time delay is specified. A value for this property should only be asserted for time delay of L-function, and for I2t of the S and G function.

I2TApplicability IfcPropertyEnumeratedValue PEnum_AdjustmentValueType

The applicability of the time adjustment related to the tripping function.
