Up Time Magazine - December 2008/January 2009 - (Page 20) Would a job plan help to ensure quick task execution with consistent results, particularly if resources or specific conditions are required to execute the task? Could some of the tasks be performed without interfering with Production? Let’s face it, the equipment exists to make some form of product. Whenever it is down for PM, we are not making product, and likely not making money! Finally, the optimal frequency of each PM task should be deter- mined. In most cases, the data to make this decision does not exist because failures have not been tracked accurately nor in enough detail. Yet frequency is often the first place people look when they consider optimizing a PM: “Can I do the task less often?” 3-Dimensional PMOptimization addresses frequency only after applying 14 techniques that verify the task is legitimate, that it is the optimum task, and that we are performing it in the best way. Furthermore, reducing a frequency carries the potential of introducing additional risk. While this risk must be weighed against the potential benefits, consider that the frequency assigned to a particular task is often determined based upon when we are already scheduled to do other tasks. If we have a monthly PM and the need for a new task arises, we typically also include it in the monthly PM. Two Barriers to Using Vibration Analysis: Cost. Know-How. Datastick Breaks Both Barriers. PM Optimization Example using Multiple Optimization Techniques: PM on an Air Handler Unit Original PM Task: Change 8 HEPA filters on an Air Handler Unit quarterly (Figure 3) Optimization: The client installed a magnehelic gauge to measure pressure drop across the filters (modification) & determined the pressure at which the filters required replacement (now an Objective Inspection) based on air volume requirements & filter specifications. They also marked the warning zone on the gauge in red (visual workplace). This allowed Task Promotion from Type 1R Replacement Task to two new tasks: the 1st is a Type 3 Objective Inspection and the 2nd is a Type 2 Subjective Inspection. These inspections can now be performed by the operator while in the area, and are actually checked three times more often. The new tasks also do not require equipment downtime to perform. Datastick Breaks the Cost Barrier: We could say, “Datastick breaks the price barrier,” and with handheld systems from around $6,000 that’s true. But what about your total cost of ownership? Datastick keeps it low because there’s no mandatory annual fee. If you want an optional service or support agreement, you’ll find they’re designed and priced to help you, not scare you away. Datastick Breaks the Know-How Barrier: You can learn to use the handheld device in a couple of hours. If you’re short on in-house vibration expertise, don’t worry. The included Datastick Reporting System™ software for your PC is based on Microsoft Excel. That means that you can share your data, graphs, and reports with any in-house vibration analyst or outside consultant. And with our new smartphonebased SiteConnex™ VSA™-2215, you can even email vibration data directly from the field.

This example is provided for illustration purposes because it utilizes multiple techniques of PM Optimization. Although the results shown in Figure 4 are typical, there are other items to consider. For example, the filters will still have to be changed eventually; however, it will be based upon condition and the replacement will be performed as a planned & scheduled corrective maintenance job.
