Interfacing with the LS8000-3

Index Pulse & Length Thresholds

The Index Pulse and Length Thresholds can be used to control a cutter and provide pre-cut queues to the process control system so, for example, the line can be slowed prior to a cut. The Index Pulse is configured to trigger at a specified length interval, and the Length Thresholds can be configured to trigger at preset lengths before the Index Pulse triggers. The Length Threshold outputs remain high until the Index Pulse triggers and resets. The index pulse automatically resets the Length Threshold outputs—no external wiring is required.

Another way to reset these outputs is to set the Index Pulse Setting to a high value and reset the threshold outputs by asserting the Length Reset Input.

The Length Thresholds are available as an alternate output function of the

User Scaleable Pulse Output.
