QTVmini Stop Motion System
General description
The QTVmini + MiniSMG yarn stop motion system is designed to monitor any kind of moving
yarns. The unit is designed for systems with 8–180 yarns, like creels for winders, yarn preparation machines and other multi thread applications. QTVmini is easy to use with a minimum of parameters to adjust. All settings, and other user information, are
displayed on a LCD display. Sensitivity and start delay are easily set by potentiometers in the central control unit. Other settings, such as reaction time and learn
mode are set via a DIP-switch. A relearn button is easily accessible on the front side of the unit.
Main features
• The detection is made with piezo electrical elements sensing the yarn movement.
• The sensing unit, which is insensitive to dust and dirt, detects a yarn break in a few milliseconds.
• The number of yarns in operation is shown on the display.
• The number of yarns are counted during a learn period. For a style change the operator activates the learn mode under which the QTVmini system counts the number of yarns. Each eyelet is then switched on or off automatically.
• The system will, at machine start, detect if too many yarns are in operation (Anti function).
• Parameters such as sensitivity and reaction time can easily be set from the central control unit. All settings are common for all sensors.
• Connections are easily made by ribbon cable connectors.
