Repair Tips and ideas:

When our engineers and technicians are working on a repair in the field on any form of industrial electronic equipment there is a general rule we follow. Whenever possible fix only one problem and one section at a time. That way if a new problem is introduced you know when and where it happened. We have seen many technicians work on more then one area and make several changes and then when they bring up their machine a new and more menacing problem has occurred. When you make only one change at a time if a new problem occurs you know where to find the problem. If you try to reinvent the wheel all at once you may have a very hard time finding the problem. By working on a problem this way you go through the machine step by step making sure to catch any secondary problem as well saving the customer from additional down time. This plan of attack usually saves the customer additional downtime. We also offer phone support to existing customers and will try to step you through your industrial electronic problem one fix at a time as well.

If you are working on a large retrofit job and have questions contact Bill Kegley, Craig Gaulden or Terrence Harris to help guide you. All three of these men have extensive experience in the field in industrial electronic retrofit jobs. So if you have a system that is down and you are told the parts to get you back up and running are obsolete Specialized Electronics can find a modern day solution and retrofit out your old parts and get your line back up and running. We have upgraded old DC drive systems with AC vector Drives and AC vector motors with great success. When modifying an older system we will try to utilize as much of the original equipment as possible to help keep costs down. 

When troubleshooting an Industrial system and you find a bad AC drive or DC drive, check the output section for shorts or opens. If your output section has been damaged make sure to use a megger on your motor to make sure the motor did not short causing the drive to go bad. At Specialized Electronic Services we have seen many AC drives and DC drives go bad due to a motor shorting out. On DC motors make sure the Armature is not shorted to ground or to the field. On the field check the field resistance and look for bad brushes as well as Meg the field to ground and to the Armature. On AC motors check all three phases one at a time to ground with a megger as well as check for phase to phase shorts. We have had more the one customer get a drive repaired and put it back in the system and have it fail on start up due to a bad motor they did not check out. 

Large Retrofit Job:

Specialized Electronic Services recently did a large retrofit job removing some obsolete Square D Omegapak AC Drives and replaced them with some Square D Altivar ATV61 series AC drives. The original VFD units were in factory made buckets and we pulled out the old VFD units and had the new units dropped into the existing bucket saving the customer a lot of money by not having to replace the entire bucket. The job was done for the City of Greenville in a water treatment facility and if you have a need for a retrofit job in your facility call us to see what we can do to retrofit out your obsolete equipment. At Specialized Electronics we try to use as much of your existing equipment as we can to save you money. Many customers think they need to replace a whole bucket or panel when doing a retrofit of an obsolete drive. In many cases this is not true or necessary. If the AC drive is the only component bad in many circumstances we can retrofit out the drive for the end user and maintain using the rest of the existing components, saving you time and money.
