MCP's technical training specialises in practical learning programmes for upskilling technicians and operators. When you're doing an RCA to determine the source of a fault, you'll usually find 3 basic types of problems: physical causes; human causes; organizational causes; You can also do a root cause analysis if you want to drill down and find out exactly why a process or procedure is producing better-than-average results. Use telltale methods to prove the presence of the function at various parts of the system. If one is in doubt as to whether anything is relevant, then include it. London, 04 Oct 2023, Members: 1,095 + VAT Find which circuit may be faulty and the which components could cause those symptoms. Reading through a recent survey by the recruitment giant Reed, six in ten Londoners are looking for a new challenge.

The last step in the process is to check the system and make sure it can return to operation. Fault diagnosis is an important part of the condition monitoring process, allowing operators to not only detect mechanical irregularities buy also pinpoint the root cause of the issue and carry out repairs accordingly. The cause of the puncture may be a nail that has penetrated the outer cover. For instance, consider the example of TDR testing for underground cable. In some applications, fault detection and isolation go hand in hand; they can, of course, be separate modules of the process. How do I know my maintenance workforce is competent? After analysis, the fault in the system is located with the aid of evidence analysis. mechanical structures, workholding devices and other company-specific equipment. Film feed belts are slipping. When do you cannot locate a fault in plant or equipment? It could also save you money, especially Accurate findings from investigations require accurate knowledge. All the evidence collected must be relevant to the problem in hand. The advanced FDD algorithms can be used to produce healthy motor stator terminal current signatures and compare them with current signatures under faulty conditions. However, you may visit "Cookie Settings" to provide a controlled consent. Symmetrical faults. Hardware-based fault diagnosis methods do not deploy a mathematical model of the physics of the plant or process. Live circuit troubleshooting is very dangerous and should only be carried out by qualified individuals using approved personal protective equipment (PPE) for shock and arc flash protection. Use of self-diagnostic Some process systems or industrial machinery have designed into their build specifications, self-diagnostic faultfinding equipment. endobj Understand the problem and history. Degegates will have developed a good working knowledge of basic fault finding techniques and methods which should make them more effective and efficient with problem solving faults on their workplace systems.

We have a range of options to help you maximise your training budgets. Visually inspect the machine. Which is the best laptop in Lenovo company? Bag Length is too long. This is also referred to as "fault isolation", especially when emphasizing the distinction from fault detection. mechanical etc. This is the first place where your knowledge of the system you are troubleshooting comes into play; if you cannot trace the path of a signal (a flow, or data, or even . Fault detection is the process of discovering the presence of a fault in any equipment before it manifests itself in the form of a breakdown. Even better when you consider our business is located in a completely different time zone (somewhere in Australia). Plan for exceptions. For instance, upon breaking of rotor bars, the pulse produced in the stator current is twice the motor stator current frequency. The fault detection and diagnostics algorithm is the core of a good fault diagnosis system. On existing plant add-in the equipment you need for problem-solving. Although it is difficult to achieve a sensor that can carry out self-diagnosis of all possible faults that might arise, it is often possible to make simple checks that detect many of the more common faults. Engineering projects come in all shapes and sizes and require a variety of skills to your projects on track and within budget, often whilst managing multiple projects at the same time. required to diagnose faults on an engineered system involving two or more of the following interactive technologies: mechanical, electrical, fluid power or process controller, at sub-assembly/component level. 2013-05-01 08:55:01. These steps include collecting evidence, analyzing evidence, locating faults, determining and removing causes, rectifying faults and running a systems check. Moreover, the necessary alarms can be triggered and fault diagnosis can be conducted, so the operator/technician can take appropriate action. The algorithm then correlates the impact of these conditions on the degradation of bearing health and predicts the failure rate and health condition of the overall motor. Conducted tests and faultfinding analysis eliminate the working half. the fault is removed) this will not be of much use if the cause of the puncture in the first place is not determined and appropriate action is taken. Now, if the fault magnitude is really high, a different methodology is required: engineers have to use active or passive redundancies to enhance fault tolerance on their devices. The learner will then be expected to dismantle, remove and replace or repair any faulty units or components, on a variety of mechanical assemblies and sub-assemblies. 6 What to do if there is no fault in a safety relay?

CJ( OJ QJ ^J aJ( !j he UhmH nH sH u!j h! Nevertheless, the Fault Detection and Diagnostics algorithm for any equipment should contain at least the four key processes listed below (these can constitute a nonlinear process as well, provided that some steps happen at the same time): We need to discuss each element in more detail to really understand how fault detection and diagnostics work. Multimeters are the most versatile of the electrical testers and, as the name implies, they are capable of many different testing functions. If used properly, one method that's been around for years can save you valuable troubleshooting time, and that's the half-splitting method. The actual approach will depend upon the item under test, but often expensive test equipment is not required, and a test meter such as an analogue test meter or digital multimeter can be used. Rectify the fault 4. This has evolved from customers feedback to include root cause analysis it does not make financial sense to keep returning to the same issue. The usage of such fault identification algorithms has significantly reduced the amount of time techs need to troubleshoot equipment and reach the root cause of the failures. In the case of the puncture, it is easy to confirm that the cause of the fault and the fault itself has indeed been dealt with satisfactorily, assuming that the tyre remains inflated. In some cases, the algorithms are sophisticated enough to even initiate failure containment actions to auto-correct the failure itself and restore the equipment to its healthy condition. Observe the system and establish what it does or does not do. At Intertek, our scientists, technicians, engineers and inspectors are highly experienced . Half-splitting can be used to find many electrical problems aside from open switches. In this article, written by John Saysell, Head of MCP Technical Training, he explains how businesses can safely introduce basic maintenance skills into the operator workforce, starting with leaving their brains at the factory gate!
