Top 4 Reasons to Implement a Control System Preventive Maintenance Program

What is Preventive Maintenance?

Preventive Maintenance (PM) is a program designed to maintain optimal function of your control systems (Variable Frequency Drives (VFDs), PLCs, etc.) in real time while also preventing deterioration and failure in the future. With regularly scheduled maintenance, PM allows users to realize the greatest return on their investment.

How does Preventive Maintenance work?

Preventive Maintenance procedures are carried out on a prescribed basis, customized to the specific needs of each control system. During PM, controls undergo various physical, visual, and electrical inspections in addition to regular maintenance procedures including predefined part replacement and fine-tuning. Any irregularities are identified and remedied before they have the opportunity to magnify and cause more serious and potentially costly damage. Each procedure concludes with full documentation of the controls system’s condition at the time, creating a history file that helps predict future maintenance needs.

Why implement a PM Program?

While there are many important reasons to implement a Preventive Maintenance (PM) program for the control systems in your facility, there are four that stand out from the rest:

     1. Prolongs Life of Investment

Did you know that a drive without Preventive Maintenance could have a life expectancy as low as 3-4 years before problems climb beyond economical repair? The same drive could have a life expectancy of 12-15 years or more if well maintained. Without PM, it’s difficult to tell if your drive is operating under ideal conditions or not. Non-ideal conditions put stress on crucial components such as IGBTs, capacitors and other sensitive electronics that can significantly reduce their life-expectancy. With PM, operations users realize low peak-demand rates, drive reliability and an improvement in the return on investment of their drive.


     2. Minimize Downtime

Control system failure can cause major downtime in operations, costing businesses thousands of dollars. Preventive Maintenance is meant to reduce the chances of control system failure and the severity of failures if they do happen. Industries at the highest risk for losing a great volume of assets due to downtime include pharmaceutical, medical, wire and cable, and more. For example, a pharmaceutical company that relies on their drives to keep their facility and laboratories sterile could lose hundreds of batches of product and have an experiment that has lasted years be completely compromised by an unsterile facility if their drives were to fail.


     3. Maximize Energy Savings

To paraphrase and old pirate yarn, “Dead drives save no energy.” Preventive Maintenance programs ensure that control system’s energy consumption matches energy requirements. Mechanical systems controlled by drives and/or PLCs that unnecessarily operate at high energy consumption, endure stress that can reduce their life expectancy. With PM, systems run efficiently, reducing energy related costs and the facility’s overall carbon footprint.


Control Systems Messy Wiring Preventive Maintenance
Messy wiring can cause difficulties during trouble shooting and even lead to control failure if not remedied.

     4. Maintain a Knowledge Base of Equipment

After each Preventive Maintenance procedure, the information collected including inspection, updates, comments, suggestions and more is logged into a system that contains the operating history of each drive or PLC with PM. At first, this may sound like a small piece of a large puzzle when it comes to the upkeep of control systems. However, having a knowledge base of a control system’s history can be highly predictive for future maintenance needs and problems. In the long run, this helps decrease damage related costs and increase operational reliability.


Why EDC?

Electronic Drives and Controls (EDC) has over 50 years of experience in commercial and industrial variable speed drive maintenance, repair and retrofits- servicing over a quarter million drives to date. Over those 50 years of service, we have built a proprietary Preventive Maintenance program with customized checkpoints to assure consistent and thorough inspection of all our client’s equipment.

Commonly, organizations whose focus is on the sale and support of single brands of VFDs or other controls are at a technical disadvantage when faced with providing effective, cost-efficient maintenance and service on competitor’s equipment. Our highly trained and nationally recognized service engineers have experience with a wide variety of equipment, as we are a factory authorized/factory trained service center for over 40 drive brands, and have alliances with world-class hardware and software providers. This allows our engineers to accurately identify areas of concern before they turn into more costly, complicated issues- regardless of the control system’s brand, age, model, etc.

In half a century of service, EDC has also remained brand-neutral in an effort to operate in our clients’ best interests. Remaining brand-neutral has allowed us to give product recommendations to our clients without the influence of a third party. This also allows us to be as transparent as possible with our clients, documenting and sharing all information collected during PM visits and making suggestions for proper care between visits.

Our field service engineering team is available 24/7/365, providing immediate response to any drive and PLC repair, service installation, maintenance, start-up need and more. For more information regarding Electronic Drives and Controls, Inc. please contact us at 973-428-0500.
