ACTUAL
The ACTUAL line of the
display shows the number of units which have been produced during the
current shift. This count is automatically zeroed at the start of the
shift and is incremented each time the production line sensor indicates
that a unit has been produced.
TARGET
The moving target shown
on the TARGET line of the display gives the total number of units which
should have been produced at the current point in the shift. It is
calculated using the following formula:
Moving Target = Elapsed Shift
Time x Total Shift Target
Total Shift Time
Where 'Elapsed Shift
Time' is the number of seconds elapsed in the shift. 'Total Shift
Target' is the total expected production for the shift. 'Total Shift
Time' is the number of seconds programmed for the shift taking into
account any break times which may have been programmed into the shift.
VARIANCE
The VARIANCE line on the
display unit shows the TARGET value subtracted from the ACTUAL value.
The VARIANCE value will be positive if production is ahead of target and
will be negative if production is behind target.
Customer Options
The display unit is microprocessor controlled and the programming can be
modified to suit individual customer requirements.
The Actual, Target, and
Variance lettering on the front panel can be easily modified for
different applications.
A barcode interface or
serial keyboard can be provided for entering model numbers which are
shown on the top line of the display unit.
