Sometimes Machine Manufacturers Put Things In Silly Places

This motor controller came into our workshop with a note that said circuit breaker blew. The controller was covered in grease and oil which made it quite slippery. When we opened the controller, it was even worse. The oil and grease was clagged between the circuit boards and many of the electronic components looked like they had baked in an oven. The controller dated back to the 1980s or 1990s and how it ran in this condition is a mystery till just recently.

After talking to the client, apparently the original machine manufacturers mounted the controller near the machine’s oily waste chute with a very thin sponge filter in front of the cooling fan. The filter had dislodged at some point, and the waste oil and grease had ingressed.

Thankfully our repair database (which we have built over many years from repairing other client equipment), showed similar controllers which meant we could identify many of the cooked components. After a lot of pressure cleaning and wiping, and replacing most of the electronic components, the controller was refurbished back to brand new condition. We also supplied a new sponge filter.

Our client was ecstatic as the controller was many years old and he could not purchase a new one. Thankfully we were able to save his multi-million-dollar asset for many more years of service.

Business Flexibility Is Always Vital To Meet Today’s Client Requirements

An energy producer recently approached us with a large number of complex control cabinets for urgent refurbishment. Each the size of a large bar fridge, these water-cooled cabinets were filled with smart electronics to control Megawatts of outgoing electrical power.

As the equipment was mission critical, and the overseas manufacturer only wanted to sell new with 4 months delivery, our client was desperate.

With hundreds requiring refurbishment, the time to process each was unfeasible even with our state-of-the-art automated diagnostic tools. The cabinets had no tech. documentation or schematics, so our engineers needed a different approach.

Diagnostics with a bespoke computer tablet connected to the cabinet could give us the fault data but due to the high voltages, this was uneconomical. So, our team designed a handheld computerised testing device tailored for these cabinets. We now were able to automatically test each cabinet system, so full diagnostics was 3 mins, not 3 days. The answer provided fault location, a component or PCB issue and if was repeatable or intermittent.

Our refurbishment time was 1 week and we provide a full 2 years warranty with all refurbishments.

With this innovation, Rom Control proved itself as a game changer for urgent repairs. It’s all about speed, years of experience, and reliability. Contact us on 1300 766 297 or www.rom-control.com.au/contact-us to discuss your need.

Circuit Board Conformal Coatings – Removal Can Be A Disaster If Not Done Correctly.

A Danfoss FCD 3.3Kw (5Hp) VSD arrived recently from a client for repair. We were told that the client’s maintenance crew attempted a repair on the circuit board but did further damage trying to remove the conformal coating. On dismantling, we found the circuit board was badly scratched and a few electronic components broken. Unfortunately their heavy handed trades person almost destroyed the PCB by firstly attempting to remove the coating mechanically.

So what is Conformal Coating you might ask? It is a protective layer of film applied over circuit boards and is usually a two-pack resin, an acrylic resin, silicone or Parylene. The coating helps prevents corrosion, mechanical damage, etc. and must be removed to diagnose and replace faulty electronic components. An appropriate chemical that is inert to the circuit board and components, or light heating, is the best way we have found to remove the coating. Scrapping and sanding is strongly discouraged.

After many years, Rom-Control has had to developed specific techniques with non hazard chemicals to remove the coating. So do your research before reaching for a sharp knife or sandpaper.

After much re-construction, we did clean and re-build our client’s VSD thankfully as this particular drive was discontinued many years ago. Now their machine is up and running at full speed.

Five Signs Your Industrial Logic Circuit Board (PLC, VSD, Power Supply, etc) Has Gone Bad

I recently had coffee with a client who mentioned he had a problem with a new welding robot. Recently it needed two or three attempts to initialize before it was ready but that morning, it took five attempts. The HMI kept reporting a different ‘random’ computer error.

Familiar with this type of fault, I suggested it’s an electronic issue which we need to look at. As expected, we discovered aging faults on many circuit boards. After we refurbished the electronics, the robot initialized immediately. My client was amazed and wanted to know how I knew.

From our experience, we know the five basic signs that your industrial logic circuit board (PLC, power supply, VSD, etc.) is going bad.

  1. Random Error Codes or warning beeps.
  2. Power indicators are slow to glow, flickering, or don’t come.
  3. Random data errors on HMIs, counters, printouts, etc.
  4. Random booting issues, the electronics appear to possess little gremlins.
  5. A smoldering electronic smell.

So what should you do if you suspect a logic board is failing? Sometimes a replacement electronic board might be an option but more often than not, you may have to modify the board or machine to make it fit, or there may be other configuration issues. It is usually far simpler and safer to have the original boards refurbished.

Sometimes You Need To Know Your Spare Circuit Board Works

Did you ever look for an electronic spare part, and you plugged it in, and it just didn’t work?

This happened recently to our client in the middle of a production run. The monitor mounted on the machine control panel went blank suddenly and the machine just stopped. The client didn’t realize the monitor had an integrated PLC that controlled the full operation of the machine so when the monitor stopped, so did the production run. Our client plugged in their spare monitor but as it was brand new, the machine program had not been installed so this avenue of repair was a dead end. After the screams died down, our client brought us the monitor which we realized is an intelligent Krone iPanel.

After dismantling, we found water damage which had affected a significant portion of the circuitry. The water ingress must have been over a long period as the damage included rusted connector plugs and many grounded ICs and capacitors. Amazingly we also found the short circuit cascaded through much of the other circuitry even though there was no burn or soot deposits.

 

To refurbish the iPanel, many of the discrete electronic parts had to be removed and the board reconstructed. Great care had to be taken to ensure the program was kept intact especially during the cleaning and power up stages of the refurbishment. The panel was recently installed back into the client’s machine and everything started up perfectly. A copy of the program was taken so this situation shouldn’t happen again.

Our client was extremely happy as he thought the entire mulit-million dollar machine would be rendered useless and we were able to bring it back to life. We have now been asked to audit the other iPanels installed in other machines as a Preventative Maintenance routine.

If you have invested in spares but not sure if they still work, or any other equipment that requires repair or refurbishment, contact us at rc@rom-control.com.au or send us a message at   https://www.rom-control.com.au/contact-us/
