Example 3: two-hand controlPermalink

This is the web edition of the original ‎⮫ AC500-S safety user manual, version 1.3.2. This web edition is provided for quick reference only. The original safety user manual must be used to meet functional safety application requirements.

This example describes a machine where a two-hand control initiates the dangerous movement as long as both push buttons on the two-hand control are pressed and the process provides an enabling signal.

The dangerous movement is initiated by the closing of two subsequent contactors, which are monitored via a feedback loop.
