When a control comes in to the Flight Systems Industrial Products (FSIP) facility to be remanufactured, we know that it’s already endured countless hours of rigorous work in the field and will be subjected to that and more again. To ensure that the control is ready to withstand that pressure, each control is tested before, during and after the remanufacturing process. Each product is tested in similar fashion, but the actual tests and “check points” are different based on the job the product will perform in the field.
For this example, we’ll consider a Curtis Instruments control. As the Authorized Servicenter for Curtis, FSIP is held to a high standard for quality on each and every Curtis control we remanufacture. The first test for this control will be on the powerbase, which is a pass or fail resistance test. If the powerbase fails this test, it will be separated from the logic portion of the control and rebuilt using all new Metal Oxide Silicon Field Effect Transistors, commonly called MOSFETs.
If the powerbase passes the resistance test, the control is given a low power test that simulates a motor spinning. The oscilloscope used in this test provides easy to read results to our certified electronic technicians. These results determine the course of action the technician will take when remanufacturing the control.
If the powerbase has been rebuilt, it is reconnected to its logic card after both parts have been through FSIP’s remanufacturing process. The control is then calibrated based on its specific requirements and any required programming is loaded into the control.
Finally, the control is load tested. Our load testing machine utilizes a motor that is more than 10 times as powerful as the motor that the control will be matched with in the field. The control must successfully pass this test to be given an FSIP label.
If your control has an FSIP label on it, you can be confident that we’ve run it through the ringer, in multiple locations, to be sure you’re going to get a quality product that will get the job done.
