  •  Accurately set the Correct tonnage for each Job.
  •  Detect Broken Springs, Punches, Misfeeds and Scrap.
  •  Prevent Smash-Ups by stopping the press Before the damage is done.
  •  Reduce tool setup time.
  DLM features :
  •  Displays Peak Load measured through the stroke.
  •  Large easy to read LED display.
  •  Teach button quickly sets limits to tool load in one press.
  •  Checks for Overload and Underload conditions.
  •  Press Capacity Limit protection.
  •  Key access to Setpoints and Fault Reset.

 DLM Operation.

The DLM works by measuring the dynamic force signal generated by the piezoelectric transducers mounted either on the press frame or conrods. This signal is checked again a maximum and minimum load value and should it fall outside these limits a fault is detected and the press stopped. There is a fixed Press Capacity limit that gives protection to the press event when the DLM unit is in bypass mode.

 TEACH Mode.

This is used to set the min and max limits using the current tool load. Just press the Teach button and start the press running, after a set number of strokes the DLM sets the min and max load limits automatically !

 LED Display.
 The display is clear and easy to read even in bright conditions.
The 3 cm high digits show either Total Load, Left/Right Load or a dynamic Bargraph.

 Soft-Start Function.

This function automatically
opens-up the min and max limits when the press stops so on re-starting the limits are then gradually closed back to their original values. This allows tighter limit setting when the press is running giving better press protection.

 Bypass Input.

This can be used to turn off the min and max limits while tool setting for example. The Press Capacity Limit is still checked though.
