SPECIAL NOTICE: Please check each course for verification of approval before purchasing.
This test is based on the article, A Tale of Two Testing Methods, Part Three, published in the May 2026 issue and counts as one contact hour (0.1 CEU) of elevator industry continuing education credit. This course is approved by NAEC for CET/CAT and .01 CE QEI and in the following states: Alabama, Arkansas, Colorado, Florida, Georgia, Illinois, Indiana, Kentucky, Maryland, Mississippi, Missouri, Montana, Nevada, Oklahoma, Pennsylvania, Vermont, Virginia, West Virginia, Wisconsin.
Learning Objectives - After reading this article, you should be able to:
-
- The Henning ELVI 2 System takes CAT5 testing to an advanced level using instrumentation-based devices and engineering-derived and proven methods of measuring and documenting stopping forces.
- ELVI 2 test reports incorporate measured values of velocity, acceleration/deceleration and specific loads (including required levels), which, in turn, are used in algorithms that directly and accurately measure system stopping capabilities. Northing about this system involves "simulation". All results are based on direct measurements.
- You will see measures of force as gravity values and will learn and understand how much force (in g) is needed to effect safe stops of the elevator being tested.
- Measurement results will accurately and reliably show when repair or maintenance is needed. Additionally, measured values of some "passing" results will show that attention may be needed in the shorter term - i.e., before the next five-year test interval. Technician/mechanic experience and professional judgment add to this important work.
- Aspects of elevator system performance are revealed in this testing, which improves maintenance and ultimate safe operation of elevators that receive the benefit of this testing method. These advanced benefits are not possible using just weights and observing stops.
