Altra Easy Series - Wichita Clutch - #2

Load Cells measure the force in the web and compare that force to the set point tension in the controller. If there is any variation, the controller automatically increases or decreases the output, thus maintaining constant tension.

The Dancer indicates a position error which is proportional to the web tension, and the controller compares that position to the set point within the controller. If there is any variation the controller automatically increases or decreases the output, thus maintaining constant tension.

Ultrasonics can be used in open or closed loop mode with the controller. The signal from the ultrasonic device is used to measure the diameter of the reel.

This program provides a powerful yet easy to use graphical tool for diagnostics enabling fast and efficient commissioning.

The recorded data can be exported to a spreadsheet, or text file or as an image which may be used for a variety of purposes. It can even be replayed and analysed whilst the controller continues background logging, which is very useful if there is an underlying problem.

The status of the controller's input and output signals are shown on the screen. The entire production process can be recorded to a PC or storage medium for quality control or inspection by your customer.

Up to nine different materials with varying parameters may be preset in the controller.

Once configured, the operator pre-selects the material he is working with by a simple key selection. The controller will then reconfigure itself automatically. You do not need a PC connected once the system is configured unless you wish to record the process.
