Safety-control in a paper cutting machine

Description

In a cross-cutter, safety components need to be reliably evaluated. These include signals related to the E-Stop of machines and paper cross-cutters, moveable guards and blade guards (open, closed), feeder table and roller (raise/lower) as well as safe jog functions. Previously, the safety components were individually wired over multiple safety relays. This led to great expense and should be improved.

Solution

The MSI 100 programmable Safety Controller (standalone Safety Controller) and MSI 200 programmable Safety Controller (expandable Safety Controller) with MSI-EM I/O extension modules are used. This solution offers a variety of inputs and outputs and does so using just one evaluation unit instead of many individual components. As a result, considerable simplification and savings are achieved during wiring.
