In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

Because the wiring and the inputs and outputs (I/Os) are the most vulnerable elements in a system, be sure to locate and identify these elements in the problem circuit. Sometimes, the only way to test ...

Locomotion is a complex motor act that, to a large degree, is controlled by neuronal circuits in the spinal cord. Using a systems neuroscience approach in several model systems of non-limbed and ...

The Machine Primary Control Elements (MPCE) 1 and 2 are typically a relay with force guided contacts. When a safety interlock, light curtain, or e-stop switch opens a circuit, the MPCE NO contacts ...

New research into Parkinson's disease suggests that many of the problems suffered by patients -- difficulties in initiating actions, slow labored movements and tremors -- can be understood in terms of ...

"The complexity of photonic integrated circuits is rapidly increasing, requiring a breakthrough to be able to calibrate and control them. The technique we developed overcomes this challenge, ensuring ...

Researchers at Karolinska Institutet, Sweden have uncovered the molecular logic underpinning the assembly of spinal circuits that control the speed of locomotion in adult zebrafish. The study has ...

Fear is a behavioral adaptation which may be innate but can also be a consequence of conditioning. However, until now, the underlying neuronal circuits have remained largely unknown. Now, scientists ...

Page 2 of 3 Higher Capabilities for Safety-Rated Control Circuits May 01, 2005 SAFETY interlocks, safety light curtains, and other safety equipment are the visible part of a machinery safeguarding ...
