| Features | ||||||
| Soft Start Eliminates shocks to the web on start-up |
Yes | Yes | Yes | Yes | Yes | Yes |
| Anti-Coast Prevents web tension from dropping on stop |
Yes | Yes | Yes | Yes | Yes | Yes |
| Splice Maintains tension on material during splice for more successful splices |
Yes | Yes | Yes | Yes | Yes | Yes |
| Taper Gradually reduces the tension on your material as the roll builds to eliminate telescoping, crushed cores & starred ends |
Yes | Yes | Yes | – | – | Yes |
| Inertia Compensation Minimizes tension variations on rewind during start or stop |
Yes | – | Yes | – | – | Yes |
| Web Break Detection Stops machine should a break occur to reduce waste and productivity loss |
Yes | – | Yes | Yes | Yes | Yes |
| Remote Setpoint Remotely input or adjust tension setpoint |
Yes | – | Yes | Yes | Yes | Yes |
| Remotely Control Tension On/Off | Yes | – | Yes | Yes | Yes | Yes |
| Progressive Gain Ensures uniform control regardless of roll diameter |
Yes | – | Yes | Yes | Yes | Yes |
| Multi Cal Save up to 11 different calibration routines to allow for different wrap angles and/or a wide span of Tension ranges |
Yes | – | – | – | – | Yes |
| Application Memory Storage Store multiple tension control parameters for immediate recall when running a variety of materials |
Yes | Yes | – | – | – | Yes |
| Diameter Alarms Set alarms to go off when the roll of material reaches a certain Hi or Low limit |
– | Yes | – | – | – | Yes |
| Trim Adjust Automatically increase or decrease the amount of output to your torque device to maintain required tension |
– | Yes | Yes | Yes | Yes | Yes |
| Variable Wrap Eliminates the need to isolate the tension sensing roll and allows for roll contact to be made to only one side of your web |
– | – | Yes | Yes | – | Yes |
| Range Expansion Eliminates the difficulty in matching torque, tension, and stopping requirements of larger rolls to ensure maximum productivity |
– | – | Yes | Yes | Yes | Yes |
| Dual Calibration Calibrate the same load cell(s) with TWO DIFFERENT RANGES. Ideal for driven applications where the tension ranges are very high. |
