Malfunction Detector

RDM-4

Strain Monitoring Die Protection System

Only to press the setup button, RDM-4 sets the best monitoring range automatically.

RDM-4 is epochal new product designed and developed to make precise detection for slug by jamming die hitherto difficult to detect. The unit checks delicate changes accurately at a time slug is produced or other changes occur and stop the press machine promptly. An analog wave form produced at each stroke of the press machine is detected by a sensor mounted on the frame of the press machine and operationally processed with a built-in microcomputer to ascertain right or wrong. using with our slug detector MICRON-3, more effective detection is available.

Features

  • Easy to use.
  • Start operating with the simple push of the setup button after changing dies.
  • Interactive LCD dramatically simplifies operation.
  • Sensors are mounted to the press, eliminating the need to adjust sensors at every die change.
  • RDM-4’s unique “Area under the curve comparison method” enable to detect floating slug, slug pulling for jamming dies
    hitherto difficult to detect.
  • Supports a wide range of fault detection, double sheet feeding, material end, mis-feeding, etc.
