Training and travel during a climate crisis and a pandemic

An illustration of a line of passengers with suitcases, wearing masks.

It sounds like the opening chapter of a dystopian novel; the world is being affected by a climate crisis that makes it difficult or impossible for people to live outside, and a concurrent pandemic is making it dangerous to stay indoors with other people. This world exists today, and it’s not some dark vision about…

Understanding safety functions: Indicators and alarms

A man in a white hardhat and high-visibility vest stands in a large process plant control room holding a walkie-talkie and looking towards a screen with alarm annunciations displayed. The control room is mostly white, so the man's vest, the instruments and displays pop out of the image.

This is the final installment in the series on understanding safety functions. When indicators and alarms come up in conversations between machinery controls engineers, large process plant control rooms like those shown at left often come to mind. While this is certainly true, there are many instances on smaller machines and assembly lines where alarms…

Understanding safety functions: Fluctuations, loss and restoration of power sources

Voltage vs time plot showing a voltage sag condition.

Control systems must be protected against fluctuations and power loss, whether electrical or fluidic. Fluctuations and losses are well defined in IEC, IEEE and ISO standards. Careful design of electrical systems, including the use of UPSs for electrical control systems and the careful design of pneumatic supply systems, including the proper sizing of pneumatic accumulators for compressed air-powered logic, is essential.
