Demystify phase sequence & electric chain hoist control

This course explains what 3-phase AC power phase sequence is and the impact it has on electric chain hoist control systems.  The presentation contains a brief overview of operation of 3-phase electric motors and control systems.  Subject matter includes overview of phase reverse and phase OK features, phase swapping, best practices per ANSI E1.6-4, and a lot of visual system examples.  Students learn why phase swaps within the system could result in incorrect operation and possibly hazardous conditions.

System examples include every scenario of an electric chain hoist control system with phase reverse and phase OK indication operating in the field, for both input power phase sequence possibilities, for both in-phase and out-phase controller setups, for both hoist phase wiring possibilities, and for both engaged and disengaged conditions of the phase reverse feature.  These examples detail the setup and the resulting performance of the system, for example the condition of the phase OK light and how actual chain movement compares with operator input command.

Offered online only, administered live on a web conference platform.

This is an ETCP-recognized course providing 2 renewal credits.

Phase sequence training is great for entertainment riggers, electricians, and user operators who want to better understand electric chain hoist operation.
