Webinars

Modern safety systems allow us to do more than just turn off the machine to reduce the risk of injury to the operator. In this technical webinar we explore the various safe stop and motion techniques such as safe speed monitoring, which aid in reducing risks associated with direct access to the machine.

In this webinar we discuss:

• Safety Functions and Monitoring
• Modes of use for machines
• Stand-still detection
• Safe stop techniques including Safe Torque Off
• Stop categories
• Drive based safe motion functions and instructions
• Application examples

AZ/NZS 61439 is the new series of standards that covers the requirements for switchboards. Join us for an informative audio discussion with two of our switchboard solution specialists. We will be discussing the AS/NZS 61439 standard in general with answers to frequently asked questions.

Hazardous areas exist in places we might not all be aware of, learning to identify and select equipment for these environments is critical. In this technical webinar, we will be exploring what constitutes a hazardous area; the explosive nature of materials, and how material properties are grouped to aid selection of hazardous area equipment based on certification and marking.

In this webinar we discuss:

• What is a Hazardous area?
• Conditions for Explosive Atmospheres for Gasses, Vapours, and Dusts
• Properties of Gases, Vapours, mists and Dusts
• Material Grouping, T classes, EPL's and Zone Classification for Gasses and Dusts
• Types of protection, how they work & where they can be used
• Equipment Certification & Marking

In high risk safety applications, diagnostics and fault detection are absolutely essential. This technical webinar looks at the fundamentals of the safety monitoring relay's main functions in a safety control system, and delve into some of the measures for Diagnostic Coverage with respect to the machine safety standards.

In this webinar we discuss:

• Typical fault lists and exclusions
• Diagnostic Coverage (DC) and its importance in the safety control system
• Fault monitoring and detection
• Safety monitoring relay logic and examples

In this session, we will specifically be looking at Presence Sensing devices; their application, special functions and specific guidelines and rules for how they should be used, and delve into some of the specifics on how some of these devices work.

In this session, we will specifically be looking at Interlock Switches; their application, special functions and specific guidelines and rules for how they should be used, with respect to the machine safety standards.

IE3 / IE4 motors (high efficiency motors) have very different characteristics to older designs we are used to. The characteristics pose challenges for connected switch gear, circuit breakers and contactors alike. They have also forced industry to change expectations in performance parameters to do particular jobs. In this webinar, we discuss some of the issues involved in these subjects.

While there is a lot of information floating around on the subject of Arc Flash, it is safe to say there is a lot of confusion within industry concerning the responsibilities and obligations to mitigate against this occurrence. This technical webinar aims to break down the Arc Flash subject and clarify the obligations onsite and the various mitigation strategies available.

This webinar covers:

• What is arc flash (principles)
• What are sites required to do?
• Mitigation strategies
• AS/NZS 61439: Low-voltage switchgear and control gear assemblies
• Electrical Protection
• Arc Fault Detection Device (AFDD)
• Other Detection Methods
• Arc Quenching
• Personal Protective Equipment (PPE)
• Remote operation

This webinar covers:

• Meaning of selectivity and expected outcomes
• The basics of circuit breaker selectivity
• Defines types of faults and expected fault behaviours
• Discusses Prospective fault current s and how they are derived
• Defines the requirements and definitions according to AS/NZS3000:2018 and AS/NZS60947-2:2015

This webinar covers:

• Why is Type 2 co-ordination required?
• The testing processes from AS/NZS IEC 60947.4.1:2015
• How these are applied to type 2 tables for IE3 Premium efficiency motors
• Considerations for site operations
