U4 Open Loop Diameter Based Tension Controller

Open-Loop Diameter Based Tension Control has evolved with all the NEW U4. The U4 brings advanced features (typically found only in closed-loop control systems) such as soft start, anti-coast, and taper tension, to open-loop tension control. Compatible with a variety of inputs the U4 ensures accurate tension control from full roll to core.

Benefits

• Extremely Flexible
  • -Compatible with Ultra-Sonic Sensors, Proximity Switches, Laser Sensors, & Rider Arms
  • -Use it as an Unwind or Rewind Controller
  • -Works with Pneumatic or Electric Brakes & Clutches
  • -Compatible with Motor Controllers
  • -Available as a Panel Mount or Surface Mount
• Stored Tension Parameters
  • The U4 Open Loop Tension Controller allows you to save up to 9 groups of tension parameters for immediate recall to get you machine up and running quickly
• Set It & Forget It Technology
  • With a few key button presses your machine operates at maximum efficiency without constant monitoring
• Enhanced Productivity from Shift to Shift
  • Standardized settings combined with the stored tension parameters gets your application up & running quicker while eliminating variations in productivity from shift to shift.
• Programmable Diameter Alarms
  • The U4 Open Loop Tension Controller features a programmable high and low diameter alarm for slowing & stopping your roll based on set diameters.
• Unwind & Rewind Functionality
  • Soft Start: eliminates shocks to the web on startup
  • Anti-coast: prevents web tension from dropping on stop
  • Taper: builds excellent rolls while eliminating telescoping
  • Splice: maintains tension for more successful splices
• Remote Set-Up, Programming, & Monitoring
  • Utilize the integrated USB port to remotely set-up the U4 Open Loop Tension Controller as well as monitor roll diameter/output. Store programming parameters on your computer and upload to the U4 via the USB port.
• Versatile Set-Up and Operation
  • Set-up in Imperial or Metric Units. Features both 0-10 V or 4-20 mA outputs.
• Trim Adjust
  • Increase or decrease the amount of output to your torque device to maintain required tension
