These issues can occur during both the starting and running phases of electrical equipment.<\/p>\n\n\n\n<p>Even though field control panels are provided with alarm systems or data loggers in the main control room, they may not always reveal the exact cause of a fault. In such situations, this fault finder becomes a valuable tool for Fault Detection and Diagnostics in Equipment Maintenance<\/p>\n\n\n\n<p>Presented here is a fault finder circuit based on the STM32 Blue Pill development board. Eight digital inputs and an analogue input are chosen for fault recording. The STM32 board, connected to a laptop computer with the provided Arduino program open and its serial monitor window active, will print the input number, contact status (logic 0 or 1), and its operation time in milliseconds whenever a change in contact state occurs. The \u2018serial print\u2019 feature of the Arduino IDE is used to record the status and operation time of the inputs.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"760\" src=\"https:\/\/www.electronicsforu.com\/wp-contents\/uploads\/2024\/07\/Authors-prototype-on-breadboard.jpg\" alt=\"Fault Finder Tool\" class=\"wp-image-144962\" style=\"width:401px;height:auto\" srcset=\"https:\/\/www.electronicsforu.com\/wp-contents\/uploads\/2024\/07\/Authors-prototype-on-breadboard.jpg 1000w, https:\/\/www.electronicsforu.com\/wp-contents\/uploads\/2024\/07\/Authors-prototype-on-breadboard-500x380.jpg 500w, https:\/\/www.electronicsforu.com\/wp-contents\/uploads\/2024\/07\/Authors-prototype-on-breadboard-553x420.jpg 553w, https:\/\/www.electronicsforu.com\/wp-contents\/uploads\/2024\/07\/Authors-prototype-on-breadboard-80x60.jpg 80w, https:\/\/www.electronicsforu.com\/wp-contents\/uploads\/2024\/07\/Authors-prototype-on-breadboard-696x529.jpg 696w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><figcaption class=\"wp-element-caption\">Fig. 1: Fault Finder for Fault Detection and Diagnostics in Equipment Maintenance<\/figcaption><\/figure><\/div>\n\n\n<p>The purpose of this device can be explained with the help of the prototype shown in Fig. 1.

However, determining which contact initiated the trip can be challenging. In such situations, if the suspected and available duplicate logic contacts of the circuit are wired to this \u2018fault finder,\u2019 the first faulty contact can be identified from the contact changeover time recorded in the laptop\u2019s Arduino IDE serial monitor. Thus, the fault can be easily found, analysed, and rectified in a brief time.<\/p>\n\n\n\n<p>The prototype on a breadboard is shown in Fig. 1.
