With the necessary sensors, all the above requirements can be fulfilled using a programmable logic controller (PLC) based system. Displacement sensors, either linear variable differential transducer (LVDT) or optical, are placed along the length of the window at distances of 10 cm each, which will allow the detection of window displacement and acceleration (care is needed to ensure that the sensors are not damaged by the window movement). Software automation systems used to run the test sequences must be incorporated with software timers in order to determine the time taken for a particular test event or to measure the duration of certain test events.
These PLC-based systems usually are able to perform only a single test on one power window at a time. Multiple tests usually require multiple setups and multiple software test sequences. Moreover, each test sequence requires a separate result plot: voltage vs. time, current vs. time, displacement vs. time, and so forth. This application note describes an affordable, reliable solution that is capable of running multiple tests in the same test setup and combining multiple result plots on a single screen, as compared to a traditional PLC-based system.
