Switching into Safety Engineering - #4 Designing a Safety Related Control System
Our fourth topic in the series sponsored by Euchner drills down into the necessities of designing a good machinery safety control system.

What considerations need to be taken into account when designing and building a safety-related control system? What is the process?

This webinar will highlight good practice for designers and end users, whilst highlighting some of the biggest omissions that they might make. Examples include:

Redundancy
Redundancy is the use of two separate shutdown paths or ‘channels’ to ensure safe operation in the case of a single failure. In the case of a guard interlock, it may include two separate safety interlocks each with their own mechanical element, or a single device sharing a mechanical element but with two or more control outputs and consideration being made for the common parts of the solution.

Output Signal Switching Devices (OSSD)
An output signal switching device (or OSSD) is an electronic device used as part of the safety system of a machine. It provides a coded signal which, when interrupted due to a safety event, signals the machine to shut down. It works by converting the standard direct current supply, usually 24 volts, into two pulsed and out-of-phase signals. The benefit of this is to avoid the possibility of a stray signal keeping the machine operating while actually in an unsafe condition.

Terms such as Category, Performance-Level, Dual-Channel, Redundancy, Series Connections are often misunderstood, but here we provide an essential insight.
