Appendix B Availability
B.1 Overall Equipment Effectiveness - Availability Tools
B.1.1 Introduction
Availability is a measurement of equipment uptime. It is the amount of time that the equipment
is ready to run when required by production. This is one of the three key metric of OEE and is
available for Videojet DataFlex 6530.
The ‘Availability’ tool helps to isolate operational versus equipment issues and enables the user
to track the printer downtime and view the downtime statistics. The screen of faults that allows
the analysis of runtime measurement data helps the user to understand and eliminate the more
frequent causes of both equipment and operational downtime.
The availability shows two basic availability metrics simultaneously:
• Equipment Availability
• Operation Availability
Note: Operation Availability can be changed between two separate production time proxies as required by
the user: "power on" and "running" mode. For more information, refer "Operation Availability" on
page B-2.
Where
• Operating Time is Total Printer Uptime
• Planned Production Time is the Actual Line Run Time Expected*.
*Based on proxy selected 'power on' or 'running'.
B.2.2 Equipment Availability
Equipment Availability tracks the downtime directly related to an internal error (fault).
Equipment Availability is defined as
‘Equipment Total Time’ is the total amount of time for which the Equipment is turned on (has
power applied). If the equipment is powered down when a fault is active, the amount of time
that the equipment is off is also included in this equipment total time.
‘Equipment Downtime’ is the amount of ‘Equipment Total Time’ the printer has spent in a
‘Equipment Fault State’. ‘Equipment Fault state’ is defined as the period where the equipment is
not available due to a fault identified as a equipment fault. For more information, refer Service
Manual.
