VIDEOJET DataFlex 6530 - F.3.3 Operation Availability

F-2 Videojet DataFlex 6530 Service Manual - Rev AA
F.3.3 Operation Availability
The Production Time Proxy allows the availability calculation to change between customer
selected operating modes, either ‘Running’ or ‘Power On’. The production time is defined based
on the production time proxy chosen:
• Running: If both equipment and printer are switched ON.
• Power On: If the equipment is switched ON irrespective of the status of the printer.
If the equipment is powered down when a fault is active, the amount of time that the equipment
is off is also included in the production time.
Where,
‘Running' time is the time when equipment is ON or requested to be turned ON.
Where,
Power ‘ON’ time is the time for which the equipment is switched ON irrespective of the status of
the printhead.
‘Operation Downtime’ is the amount of ‘Production Time’ the equipment has spent in an
‘Operation Fault State’. ‘Operational Fault State’ is defined as the period where the equipment is
not available due to a fault identified as a operational fault.
Operation Downtime
When the equipment enters a printer fault state the downtime counter starts. The equipment
remains in this operation fault state until the fault is cleared. If the equipment is powered down
in a operation fault state, the downtime counter continues until equipment is powered on and
the fault is cleared.
