Portable Fixed Speed Low Voltage Chain Hoist Control Repair

16 ETCP Renewal Credits

Learn how Motion Labs portable fixed speed low voltage chain hoist control equipment works and how to repair it.  Classes are limited to ten trainees and taught in a dedicated training space with a mix of slide deck presentations and hands-on work. Hotel accommodations conveniently located next door with discounted rates for attendees.

Course description:
Presentations provide in-depth theoretical training. Operation demonstrations and hands-on simulated repairs with MLI equipment provide applied learning and experience in a controlled environment.  We break the system down into four main circuits and explain the function and properties of each circuit and all the components in the system. Upon completion of this course, attendees will be able to diagnose and repair issues with Motion Labs portable fixed speed low voltage chain hoist control equipment, as well as understand basic system operation. MLI company certification available upon successful completion of evaluation.  

Topics include:

• System design, components, and basic operation
• Techniques for diagnosing and troubleshooting
• Phase reverse
• Contactor enable
• Relay/contactor function
• Maintenance and repair of cables

Instructors:
Classes are taught by skilled Motion Labs employees with many years’ experience designing, building, installing, and repairing Motion Labs equipment.

Audience:
Hoist control repair training is great for entertainment riggers, electricians, user operators and repair technicians who use Motion Labs control products and want to diagnose or repair the equipment themselves.

Requirements:
To maintain classes that are concise and focused on the intended subject matter, we require trainees to know and understand the following prior to attending: 

• Basic electrical safety
• Basic electrical circuits
• Operation and use of basic electrical test equipment
• Comprehension of schematics, wiring diagrams, and component nomenclature
• Basic operation of electric chain hoist systems

Provided:

• Morning break, lunch, and afternoon break with food and beverage
• All required tools
• Discount for local lodging

3-Phase AC Power

2 ETCP Renewal Credit

This course explains the basics of alternating current (AC) power. It contains a brief review of electrical theory basics and an overview of how AC is created and transmitted. Students learn about electromagnetic fields, induction and power generation, effect on loads, AC compared to DC, frequency, supply and system configurations, single‐phase vs. three‐phase, proper syntax, and common North American and European voltages. This course intends to build a solid foundation upon which other more advanced courses can expand. This course will be offered online only, administered live on a web conference platform. This course is intended for entertainment riggers (both arena and theatre), entertainment electricians, user operators and similar who want to better understand 3‐phase AC power and strengthen their core electrical knowledge before learning more advanced topics.

Schedule: Wednesdays 10:30 a.m. or 1:30 p.m. EST (duration 2 hours)

Phase Sequence

2 ETCP Renewal Credits

This course aims to demystify 3‐phase AC power phase sequence 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. This course will be offered online only, administered live on a web conference platform. This course is intended for entertainment riggers (both arena and theatre), entertainment electricians, user operators and similar who want to better understand electric chain hoist operation.

Schedule: Thursdays 10:30 a.m. or 1:30 p.m. EST (duration 2 hours)
