– Introduction
Three batch counters can be set to either top-stop the press or signal programmable limit switch
(PLS) outputs when their presets are reached. The total hits counter counts all hits on a tool, and
keeps track of the last recorded number for the previous job. With the optional Advanced counter
mode, you can set the good parts counter to give an accurate parts count when multiple parts are
produced on each stroke or when multiple strokes are required to produce one part.
•
Reset SmartPAC PRO. You reset SmartPAC PRO whenever the press is stopped because of a
malfunction. The malfunction is described in a fault message, which displays on the SmartPAC
PRO Servo front panel when the fault occurs, making it easy to troubleshoot the problem. See
Chapter 7 for documentation of fault messages.
•
Review recent errors. SmartPAC PRO’s Error/Event Log feature displays the 100 most recent
errors and events that have occurred at the press. Errors (i.e., incidents that cause the press to
stop) are shown along with the stroke count and ram angle at which the error occurred. Events,
such as tool changes, are displayed with the date, time, and stroke count. The Error Log is
accessible from the Main Run Menu.
•
Set timing for sensor inputs (DiProPAC Only). You can specify the portion of the stroke
during which you want installed sensors to monitor press operation. Up to 32 sensors can be
programmed, allowing detection of malfunctions such as stock buckling, misfeeds, die overload,
and improper part ejection.
Sensors Available for DiProPAC
DiProPAC, the SmartPAC PRO die protection option, checks output from sensors monitoring the die
and sends a stop signal to the press when it detects a malfunction. Sensors can be mounted on the
press or die.
Any electro-mechanical sensor can be used with SmartPAC PRO Servo as long as it can switch
between an open state (i.e., sensor circuit to SmartPAC PRO open) and a closed state (i.e., sensor
circuit closed to ground or “grounded”). All types of NPN electronic sensors (e.g., proximity,
photoelectric, and fiberoptic sensors) can be used as can simple contact sensors and probes. If you
have questions about whether a certain sensor will work with SmartPAC PRO Servo, contact Wintriss
Controls.
Wintriss offers a wide range of sensors. Those that can be used with SmartPAC PRO Servo with
DiProPAC are shown below. Detailed application information is available. Many sensors made by
other manufacturers can also be used.
•
Miniature fiberoptic photoelectric sensors
—Thru-beam and reflective types are available with
adjustable sensitivity and the capability to detect objects as small as .0006 in. (.015 mm). Require
12 to 24 Vdc power source.
•
Proximity sensors
—Miniature electronic sensors that detect metal objects passing in front of the
sensor barrel. These sensors have no moving parts and are not affected by water or oil. Require
12 to 24 Vdc power source.
•
Misfeed detectors
—Designed to monitor non-working, spring-loaded pilot punch position,
stripper position, or other material location applications.
•
Short feed sensors
—Used to ensure that material is contacted at the fully advanced position.
•
Overload sensors
—Used to prevent expensive die damage due to overload from slugging,
material thickness variations, broken tooling, etc.
•
Die overload sensors
—Designed to detect minor changes in shut height.
