Obsolete repairs are machinery assets that are no longer produced by manufacturers. When this occurs, this means that acquiring replacement parts is challenging. Neutronic strives in repairing obsolete parts, we aim to find a solution to all manufacturing faults. 

Challenges of Obsolete Repairs: 

Repairing obsolete parts can be challenging and costly for businesses, due to the time and knowledge required to complete the repairs. 4 reasons why manufacturing companies find obsolescence a challenge:

1)    Shortage of replacement parts: sourcing the replacement components may be a challenge or impossible, this can limit the success of getting the part back up and running. 

2)    Technical Expertise: The knowledge of the engineers is important to think of alternative solutions, or to be familiar with the issue which has occurred. 

3)    Compatibility Issues: Testing equipment limits the accessibility to fix the damaged components and fully run test the obsolete repair. 

4)    Cost: Completing the repair may cost more, due to the cost of the components required to complete the repair. Suppliers will increase prices of parts as they know they are desirable for certain obsolete repairs. 

Longevity of Obsolete Equipment 

Familiarity within a workshop is important, once your employees are trained on software, it is efficient to keep this implemented for simplicity within the workplace. This helps to minimise the need to retrain your staff on new equipment. 

Repairing the faulty part is often a quicker solution to ordering a replacement. Lead times can fluctuate throughout the year and could be a limitation to replacing the faulty part, consideration of repairs is a suggested solution. 

The lifespan of machinery can be extended when repaired correctly. Identifying faults early can be resolved and can improve the efficiency of the machinery parts for future use. 

Why does Obsolescence occur? 

The main reasons as to why parts become obsolete is because of technological developments and compatibility issues within the industry, and the requirements to meet new needs. This is common within the industry as machinery is built for longevity, which can become challenging as parts will become obsolete before the end of the machinery lifespan. 

Obsolescence also may also occur due to Government regulations which must be followed, for example environmental or energy regulations. Manufacturers may also stop production of a part due to new models which provide better capabilities to their customers.  

How can you reduce unexpected breakdowns? 

Regular maintenance is a key management system to minimise the unexpected downtime of machinery assets. Maintaining bearings, oil levels and components to OEM specifications helps to prolong the lifespan of assets, which is important when parts become obsolete.  

Implementing a condition monitoring system onto your assets will help identify the first signs of faults. The system identifies anomalies and sends alerts to show when they need to be resolved, to improve the efficiency of the asset.  

How can Neutronic support you with Obsolete Repairs? 

Neutronic have extensive in-house testing equipment and experienced Engineers who can support customers with obsolete repairs. Familiarity is key to providing a quick solution to the problem. Once our engineers have identified the issue, we will consider the cost of replacement and repairing, to see which is the best option. If the part is beyond economical repair, Neutronic can support you with supplying a replacement.

Enhancing Industrial Operations with a HMI

A HMI panel (Human-Machine Interface), is an interface or dashboard that controls a machine. They are a user-friendly way for humans to control systems within the manufacturing environment. A typical HMI consists of a display screen, input devices, audio alerts and feedback devices. Human Machine Interfaces (HMI) are simple to use. By utilizing familiar software and processes, engineers can tailor these for optimal performance. 

Component of a HMI

Common uses for HMI’s 

Human Machine Interfaces (HMI) are utilized for showcasing information graphics, automating processes, and generating reports. Playing a critical role in monitoring and controlling various systems in different industries. 

Depending on the industry will depend on the application of the HMI. Lets take a look how the panels are used in different industries:

HMI’s within the Food Industry  

In the Food and Beverage industry, there are regulations to follow to ensure food safety throughout production. IP66 rating is essential for the HMI when located in food production environments.  

The IP66 rating ensures that the interface can handle extreme temperatures and high-pressure jet washes during cleaning. Due to the regular cleaning required, water contact can cause damage to the screen and electronic connections. 

HMI’s within the Automotive Industry 

Within the automotive industry HMI’s are used to provide valuable data in relation to quality control and operator safety. This is crucial within the production line, to provide a constant high quality when manufacturing vehicles. HMI’s assist operators with fault diagnosis when breakdowns occur, this helps identify the fault and repair it efficiently to restart production.   

Where are HMI Panels used? 

HMIs are utilized across various sectors such as Food Manufacturing, Industrial Automation, Medical Manufacturing, and Transportation. They are commonly employed to regulate the equipment involved in the production process. 

HMI’s most commonly need replacing after 10 years. Overworking the HMI, irregular maintenance and unrepaired physical damage can reduce the lifespan of the HMI. 

Obsolete HMI Repairs 

Many major manufacturing brands produce HMI’s, including Schneider Electric, Allen Bradley, Siemens and Mitsubishi. Technological developments will increase obsolete HMI’s within the industry, Neutronic can repair the majority of obsolete HMI’s from all major manufacturers. 

Neutronic strive in finding solutions for our customers, we have the in-house capabilities to repair obsolete parts in our workshop. Including Mitsubishi E1020 HMI screens, these HMI’s are obsolete and are expensive to replace. You can expect to pay over £1000 for a replacement E1020. Neutronic are one of the very few industrial repair services that can repair the Mitsubishi E1020 screens. 

Neutronic offers a 24/7 service to all customers with repairs. Offerings a 12-month warranty for all HMI’s when they leave our workshop, allowing you to be confident in our repair service. 

5 Common Faults with a HMI Panel

HMI’s are attached to control machinery, and regular use means faults occur more often, common faults which are found with HMI’s are: 

Screen Freezing: The screen may become unresponsive or blank, which limits the use of the screen to control the machinery. 

Touch Screen Malfunction: The screen may fail to respond to touch points for users. 

Compatibility Issues: If you change or update your software and hardware, you may have compatibility issues going forward with your HMI. 

Power Issues: The screen may fail to start up due to a power supply to the HMI. If unexpected issues do occur power supply could be the first point of call to check over. 

Connection Issues: The connection between the HMI panel and the machinery, is important to work to deliver a usable HMI. 

FAQ’s

What is a HMI panel used for? 

HMI stands for Human Machining Interface. 

A Human-Machine Interface (HMI), is an interface or dashboard that controls a machine, system or device. It helps to create a user-friendly way for humans to control their systems within their business. A typical HMI consists of a display screen, input devices, audio alerts and feedback devices. 

How does a HMI co-operate with a PLC? 

A PLC (Programmable Logic Controller) relays information to the HMI to display the information and status requested by the HMI. Through the digital screen on the HMI, the graphics displayed showcase the information which is being generated from the PLC. 

What is the difference between a HMI and a PLC? 

The key difference between the two parts is the PLC is the logical part, whereas HMI is the graphical part.
