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 ...
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 ...
