PLS Press Automation

A programmable limit switch (PLS) provides press-position-based timing outputs for automation functions such as Feed, Eject, and Lubrication. In addition, position window outputs from these products are used by PLC’s for Die Protection and other control functions. AVG offers the widest variety of PLS products containing several unique features that benefit press operations. For example, some of the PLS’s have built-in brake monitor and motion detection eliminating the need for separate units. Motion detection supports programmable “detect-delay” to allow the press to ramp up to speed without tripping a motion fault. The Reverse-motion-disable feature provides safeguards by disabling outputs if the press moves in reverse direction. Many of these products provide press position and SPM display to eliminate separate displays for the press.
