The UKAST 508 is the revised let-off controller of the well-known KAST 197.
It can be used as replacement of KAST 197 but with its new design it allows for wider applications.
UKAST — this name stands for the really universal utilization.
The controller is designed for application of warp tension control for weaving machines and comes standard without a driver. It just gives a motor speed analog-output of 0-10VDC for external driver.
Depending on the application various motor drivers and motor sizes are available which supplies the necessary warp threads to the weaving machine and maintain the yarn tension constant from full to empty beam.
The warp thread tension is measured by a linear proximity sensor fitted to the back rest roller. The control system is equipped with dozens of function parameters, which allow an optimal adaptation to the most diverse types of fabric and weaving machines.
If fine adjustments are needed, these can be made whilst the machine is running.
