G-6 Reporting Downtime and Scrap to LETS
these cases, the period during which the press is offline and the time immediately following
press power-up are assigned to the machine state in effect when the press was powered down.
SmartPAC 2 can be programmed so that Unplanned Downtime reasons selected from the
Dialog Menu also “persist” through press shutdowns (see Making Downtime Reporting
Settings, page G-7). When this setting is enabled, both the interval during which the press
was powered down and the time following resumption of power to the press are assigned to
the downtime reason in effect when the press was shut down. One second of the period during
which the press was offline is assigned to Offline Time to document this event.
Single-stroke Mode
For hand-fed applications, a special setting can be programmed at the SmartPAC 2 (see
Setting up SmartPAC 2 to Report Downtime, page G-6) that allows the press to operate
continuously in Single-stroke mode without the operator having to enter a downtime reason at
the end of each stroke, when the SmartPAC 2 considers the press to be stopped. Instead of
looking for a change of state (i.e., from Running to Stopped), SmartPAC 2 looks for at least
one press cycle during a pre-programmed interval and, if it detects no stroke, considers that
the press is stopped, reporting subsequent time as Idle Time.
Reset Strokes Counters
Normally, a period of Idle Time, Planned or Unplanned Downtime, or Changeover Time is
ended when the operator selects “Back on Line” from the Dialog Menu and restarts the press
(see Putting the Press “Back on Line,” page G-3). However, since the operator may forget to
select the “Back on Line” item, an alternative way of terminating a period of downtime is
available.
SmartPAC 2 can be programmed to begin logging time following a downtime period to
Running Time after a specified number of press strokes. A Reset Strokes counter (see Making
Downtime Reporting Settings, page G-7) begins incrementing when the press is restarted, and
after the counter reaches its preset, LETS changes the machine state to which it logs press
time from the downtime reason to Running Time. Three different Reset Strokes counters can
be programmed, allowing you to set different restart intervals following periods of Planned
Downtime, Unplanned Downtime, and Changeover time.
Setting up SmartPAC 2 to Report Downtime
To set up SmartPAC 2 to report downtime to LETS, you make downtime reporting settings on
the Set Communications Menu and program downtime reasons on the Dialog Fixed Name
Choice Menu and the Dialog Special Choice Name Menu.
