Variable Description
Asset Scheduled
Time The Asset Scheduled Time in CheckPoint™ is any time when there is no Planned
Downtime. If your company has no Planned Downtime entered at the Company Site,
Container or Welding Power Source level (page 9.10), CheckPoint™ considers the
asset scheduled and productive 24 hours a day, 7 days a week, 365 days a year.
In order to calculate the Asset Scheduled Time accurately, CheckPoint™ must remove
any time the Welding Power Source(s) spent in the Disconnected status. There is no
way to know if the machine(s) was/were welding, faulted, etc.

For example, for an eight-hour shift (480 minutes), the Welding Power Source was
disconnected for 108 minutes. The Asset Scheduled Time for this Welding Power
Source is 480 minutes minus 108 minutes for a total of 372 minutes to be used in the
Availability calculation.
NOTE | If the Asset Scheduled Time is zero (i.e., the Welding Power Source(s)
was/were disconnected the entire time period), the Availability factor is 0%.
Operating Time Operating Time is the amount of time the machine or asset is actually working. You
reach this figure by subtracting any Unplanned Downtime from the amount of time
you expect the machine or asset to be working.

Planned
Downtime Planned Downtime is the amount of time to be excluded from efficiency calculations
because there was no intention of running production. Examples of Planned
Downtime include breaks, lunch, scheduled maintenance, holidays and other non-
production times.
Your CheckPoint™ administrator entered the Planned Downtime for the Company
Site, Container and Welding Power Source in the CheckPoint™ Manager (page 9.10).
Planned
Production Time Planned Production Time is the amount of the time you expect the machine or asset
to be working. There are two components to Planned Production Time: Asset
Scheduled Time and Planned Downtime. You reach this figure by subtracting any
Planned Downtime from the amount of time you expect the machine or asset to be
working—it’s “scheduled time”.

CheckPoint™ considers a Welding Power Source as “scheduled” unless there is a
Planned Downtime event listed for the Welding Power Source (page 9.15). If there
are no Planned Downtime events listed for the Welding Power Source(s), it is
considered scheduled 24 hours a day, 7 days a week, 365 days a year.
NOTE | If the Planned Production Time is zero (where the Asset Scheduled Time
equals the Planned Downtime), the Availability factor is 0%.
