I-2 Reporting Downtime and Scrap to LETS
All time during which the press is stopped for any reason other than a power interruption or
network failure is logged by LETS to Idle Time unless a downtime reason is reported from the
SmartPAC 2. Since Overall Equipment Effectiveness (OEE) and other efficiency metrics
assign high ratings to machines with low Idle Time values, SmartPAC 2 has been designed to
allow very precise reporting of downtime to LETS and may be programmed to require the
operator to select a specific downtime reason each time the press enters an Idle state. When
operator intervention is required, periods of press inactivity are more likely to be assigned to a
specific downtime reason than to be logged as Idle Time.
SmartPAC 2 Downtime Reporting Features
Downtime reasons in SmartPAC 2 may be reported to LETS either automatically by the
system or manually by the operator. When the press is stopped because of an error generated
by SmartPAC 2 or an installed SmartPAC 2 module, the specific fault (e.g., “Sensor 1 Part
Ejection Missed”) is reported automatically as a downtime reason to LETS.
When the press is stopped by the operator or by a piece of auxiliary equipment not connected
to the SmartPAC 2, a downtime reason must be reported manually by the operator since
SmartPAC 2 is unable to detect the reason for the interruption (see
Forced Idle Dialog Mode
,
below). Downtime reasons may also be assigned manually to provide additional detail for
periods documented automatically with specific error conditions (see
Forced Error Dialog
Mode
, page I-4).
Forced Idle Dialog Mode
If the SmartPAC 2 is set to Forced Idle Dialog mode (see
Making Downtime Reporting
Settings
, page I-7), a downtime reason must be entered whenever the press is stopped by the
operator or by auxiliary equipment. When the press stops (see Figure I-1, page I-3 for a
schematic time line), a message displays at the SmartPAC 2 stating that the operator must
enter a downtime reason before the press can be restarted. When the operator closes the
message window, the Dialog Menu automatically displays. The Dialog Menu, a selection on
the SmartPAC 2 Main Run Menu, displays a list of downtime reasons from which the operator
must select to report downtime to LETS. Refer to
Programming Downtime Reasons
,
page I-11 for instructions on how to set up the Dialog Menu.
The Forced Dialog message can be programmed to display a specified number of minutes
after the press stops (see Figure I-1). This Idle Dialog Time setting enables the press to be
stopped briefly without requiring entry of a downtime reason.
Backfilling vs. Forward Filling
LETS initially logs the time after the press is stopped by the operator or by auxiliary
equipment to Idle Time. When the operator selects an item on the Dialog Menu, the period of
time previously documented as Idle is assigned that downtime reason. Downtime can be
assigned manually or automatically, depending on how your SmartPAC 2 is programmed (see
Making Downtime Reporting Settings
, page I-7).
