Smartscan Safety Light Curtain 8K3 Series: Parallel Beam Muting

Parallel Beam Muting Sequence

​Parallel Beam Muting Sequence
  1. Initiate Mute Enable signal (ME).
  2. Interrupt M1 (2.5 second disparity timer starts).
  3. Interrupt M2 (within 2.5 seconds and disparity timer stops).
  4. Interrupting M1 & M2 (system is now in mute).
  5. Pallet load clears M3 (mute is stopped, guard active). 2.5 second disparity timer starts.
  6. Pallet load clears M4 within 2.5 seconds.
  7. Deactivate mute enable (ME).
  8. Timing sequence ends.
 
 
For increased safety integrity a third mute input is available at the light curtain safety controller.  This 3rd signal is normally taken from the conveyor transport system (mute enable).  Inclusion of the signal indicates to the safety control that the conveyor is transferring products towards the light curtain detection field, thus instructing the controller to activate a MUTE ON condition during a pallet transfer through the light curtain.
 
The parallel-beam muting configuration is suitable for scanning a range between 0.5m and 5m.
