Bookshelf v8.0: Triggers View

The Triggers view provides four subviews (Time Interval, Month-Day, Usage, Threshold, or Event) to define the triggers that activate PM plans.

Time Interval Subview

The Time Interval subview sets the interval in days between triggers that activate a selected plan. A plan can have more than one Time Interval trigger. For more information, see Time Interval Triggers. Table 134 describes items in Time Interval records.

Table 134. Items in the Time Interval Subview
Item	Description
Interval	Length of the interval between triggers, in number of days. Must be an integer.
Valid Start	The age of an asset, in days, at which this trigger becomes effective. Required.
Valid End	The age of an asset at which this trigger is no longer effective. If this value is blank, the end is set to infinity.

NOTE: The asset installation date determines the age of the asset. An asset with no installation date has an age of 0 days.

Usage Subview

The Usage subview defines the measurement and measurement parameters that trigger a PM plan. A plan can have more than one Usage trigger. For more information, see Usage Triggers. Table 135 describes items in Usage records.

Table 135. Items in the Usage Subview
Item	Description
Measurement Type	A type of reading, chosen from a dialog box.
Interval	The change in a reading that triggers a PM plan. Interval uses the units set in Measurement Type.
Valid Start	The measurement at which the trigger becomes valid. The value is in the same units as the interval.
Valid End	The measurement at which the trigger is no longer valid. The value is in the same units as the interval. If this value is blank, the end is set to infinity.

NOTE: For Time Interval and Usage triggers (which use Valid Start and Valid End settings), if the interval falls beyond the Valid End, the trigger does not fire.

Threshold Subview

The Threshold subview defines a reading from an asset that triggers a PM plan. A plan can have more than one Threshold trigger. For more information, see Threshold Triggers. Table 136 describes the item in Threshold records.

Table 136. Items in the Threshold Subview
Item	Description
Measurement Type	A type of measurement, chosen from a dialog box.

Event Subview

The Event subview defines the number of service requests in a time interval that trigger a PM plan. A plan can have only one Event trigger. For more information, see Event Triggers. Table 137 describes items in the Event subview. Both items are required.

Table 137. Items in the Event Subview
Item	Description
# of SRs	The number of service requests which, when exceeded, triggers a PM plan.
Over # of Days	The time interval, in days, during which the number of service requests must occur.
