Our repair depot in Houston has done repair work on nearly 10,000 different part numbers over the years, including many AC motor controllers. Sometimes, our customers try to do the maintenance themselves, with sometimes disastrous results. Yet when you get notes like this from customers, you only can smile and be glad to help out. It reads, “Our cleaning help said it blew fire balls out the back when he sprayed it with cleaner.” Uh, yeah.

Electronics And Heat Don’t Mix

As we here in Texas groan about high temperatures of summer, it’s important to remember that we aren’t the only ones suffering from the heat. Electronics and heat don’t mix and the combination can be disastrous.

As temperatures rise the number of businesses that lost power or experienced brown increase. During that time, many people turn on their generators or use battery power to keep machines running. What they didn’t realize was – the heat could be damaging their equipment.

Circuit systems within electronics work best at lower temperatures. Allowing systems to run for prolonged periods of time in high temperatures can decrease the longevity and reliability of devices. Solid state electronics actually begin to break down and fry at temperatures much above 120 degrees. However, the hotter the temperature – the less functional the machine will become. Most systems tend to run 10 to 20 degrees hotter than room temperature.

Within the era of technology electronic devices such as drives (VFDs), programable logic controllers (PLCs), human machine interfaces(HMIs) and power supplies have dramatically decreased in size. This causes a lot of systems to run with a higher heat density. While many companies have worked to include cooling systems within their products – cooling systems cannot keep up when devices are left in areas without air conditioning. Believe it or not, just surfing the web on your cellphone or playing games on your laptop may sound like the perfect idea during a blackout, but that heat can even damage them!

When the power is off or it is not stable and rooms temperatures are high, limit use of electronic devices.  Cooling units similar to small air conditioners can be purchased and installed to keep equipment cabinets cool.  Placing a fan in front of a cabinet with the door open will provide temporary relief, but could cause more environmental damage to the drive by allowing foreign material, dirt and water into the cabinet.  Just remember. The longer the use, the hotter the object will get.

If you experience issues with any electronic device after exposure to heat send it to Innovative IDM and we will provide a free evaluation. IIDM also stocks and sells new world class VFDs, PLCs and HMIs and can do turnkey installations. So, if you have a piece of equipment you’d like to check on repairing, contact your IIDM sale representative or email us at repairs@iidm.com.

Choosing an Industrial Repairs Service

Posted December 29, 2016 by Pepper Hastings

Categories: Blog, Industrial Maintenance

When your assembly line is down and it's time for choosing an industrial repairs and field service company, make sure the company can be reached 24/7.

After the devastating floods in Baton Rouge, our tech uses a pressure sprayer on an electrical panel in a printing plant. No, it's not plugged in.

It might take a couple of hours for a technician to arrive on the scene, but make sure the phone is answered 24/7. Here are some other tips on choosing an industrial repairs service.

  • Cheapest rates are not always in your best interest. If you want an electrician, that’s one rate. If you want a technician who can program AC drives, troubleshoot PLC programs AND fix your electrical problems, that’s another rate.
  • Does the field service company have access to parts 24/7? Are they supported by a warehouse? Do they have relationships directly with the machine component manufacturers? All of this can save time.
  • Establish a relationship with several field service companies. If you have an emergency and your primary company is busy, now what? Invite several field service companies into your plant to familiarize them with your machines. It could save you a lot headaches later.
  • Keep those industrial field service phone numbers where all of your staff can see them. Don’t waste time looking for contact information. Or scan this QR code to put your emergency contact into your phone right now.

Our customers and employees in Baton Rouge continue to endure dire conditions from the staggering flooding in that area and throughout southern Louisiana. One of our customers, a printing plant, sustained horrible damage. Everything flooded. Office turned upside down. Every control panel went under water.

On the scene, IIDM field service technician from our Baton Rouge office Joey Fairchild surmised the situation: "We are attempting to save all the wiring, term strips and relay sockets. The plan is to replace every component. I’m working on that now. I’ll let you know how it goes in a week or so. Power stayed on. However we will need to clean distribution gear at some point."

Fairchild said the plan is this:

  • Pressure wash the mud and oil coating with a degreaser. It was all wet anyway.
  • Dry with fans 1-2 weeks while parts are ordered and delivered.
  • Send flooded motors out for rebuild.
  • Send high HP drives in to IIDM repair facility for rebuild.
  • Megger test all wiring, with components removed, to find shorts/moisture.

The photos and video tells the story better than words.

Electrical Troubleshooting Fundamentals

I was reading an article on electrical troubleshooting fundamentals in Electrical, Construction & Maintenance magazine. In this article they talk about using a “divide and conquer troubleshooting” to save time.

Electrical troubleshooting becomes quicker when using the "half bracketing" technique.

Electrical troubleshooting becomes quicker when using the "half bracketing" technique.

Fellow Marine and Navy vets will recognize this a what we were taught as the “Half-Split Bracketing." This electrical troubleshooting fundamental technique is a very useful and time effective method of troubleshooting.

The basic premise of "divide and conquer" is to check the system at the beginning to determine if a simple breaker or switch needs to be energized. If everything is OK at that point, you split the system in half and check there. If you have voltage or signal there, you know that the problem lies further down the line. If you don’t have the voltage or signal, then you know that the problem lies between here and the disconnect. You keep splitting the remaining portions of the system in half until you locate the problem. This is basic electrical troubleshooting fundamentals.

When I was Maintenance Lead, Supervisor or Manager, I always insisted that the techs utilized the electrical prints and drawings for that particular piece of equipment. Now, as a field service technician in the Memphis area, I have countless times been asked to help troubleshoot a piece of equipment -- and no one has even looked at a print. They say they had been working on this equipment for years and did not need the prints. If the prints were available and used, then the problem could have been found and corrected sooner.

Use the prints when troubleshooting and electrical problem on a piece of equipment. Prints will usually determine which components are "make or break" for a certain function to occur.

By using the “Half-Split Bracketing” or the “divide and conquer” approach as mentioned in Mark Lamendola's  EC&M article, your electrical troubleshooting will become more effective.
