🚦 CATERPILLAR ECM MODULE - FAILURE ANALYSIS. Attached video of ECM computer diagnosis #faulty base on short circuit 24volts power supply. The Electronic Control Module (ECM) is a sophisticated computer which #contains electronic power supplies, central processing units, memory, sensor input circuits, and output driver circuits. ECMs are available in multiple configurations for several different #applications. The Advanced Diesel Engine Management (ADEM) ECM is used to control electronic engines. The ADEM introduce from ADEM I - ADEM III ECMs are very reliable and seldom fail. Every effort must be made to determine the correct root cause of an electrical failure. The steps below provide a general approach to #diagnosing suspected ECM faults. - Check diagnostic codes. - Check input power. - Check ground. - Check power supplies to sensors. - Check communication with Cat Electronic Technician (Cat ET). - Use an ECM in Test mode. Wiring, connectors, and components must be thoroughly checked before the ECM is replaced. Have questions, comment below! follow Ayo O.

What is a Master Tech in the Transmission World? Master Certification Master Technician Certification is the highest level of certification ATRA offers that includes all three specialty certifications as well as the additional tests required for the Master Certification. This certification includes online study guides, webinars and tests required to complete your certification for the following: • E1 - Fundamentals of Electricity • E2 - Advanced Electrical • H1 – Hydraulics • H2 - Advanced Hydraulics • M1 - Mechanical • GD1 - General Diagnosis • HS1 - Hybrid Safety • SC1 - Starting/Charging • D1 - Driveability • SS1 - Shop Safety • R1 - Removing the Transmission • RT1 - Rebuilding the Transmission • MT1 - Master Final Test Each course is a comprehensive study guide and final test to adequately measure your ability of each course. By the end of the certification you should be proficient in the course or courses selected.

The 5322A Electrical Tester Calibrator helps calibration technicians comply with new regulatory standards up to four times faster than with traditional manual, multiple-product methods. The 5322A replaces the 5320A Electrical Tester Calibrator. #marlbo #fluke #5322AElectricalTesterCalibrator #CalibrationRevolution #EfficiencyBoost #RegulatoryCompliance #NextGenCalibrator

Thomas' post below is a solid example of 'trust nothing / verify everything'. Before condemning the equipment being tested, one must first eliminate: a) Test Set: Maybe your test equipment is broken - this includes the test leads... While not always practical depending upon the circumstances, but getting another test set to validate the results is desirable. b) Test Procedure: What have I got connected wrong? I've long since forgotten how many times through the years I have convinced myself I had the relay test plan connected right - only to find something like having the test lead polarity swapped on a high-speed SEL output and the test set wetting voltage was biasing the output - making the contact look constantly closed. c) Test Technician: Is the test being executed in a fundamentally incorrect fashion?

When I first learned about VRF in 2007, I remember thinking how different the skills sets required are from installing traditional HVAC systems. Since, we have affirmed that our total focus on VRF has been critical to our success. Saying it differently, VRF is a terrible side hustle. Ben is one of our VRF Experts. Everyone at Encore is either a VRF Expert, or working towards becoming an expert excepting accounting and administrative roles.

Troubleshooting does not always mean you need to find the problem in the customer equipment. Sometimes it is your own equipment that is faulty. Here is a video where we identified that our relay test set had a calibration issue. It just had a manufacturer repair but the calibration was not up to par. Drifting outputs matters when you are trying to verify 5 minute stability and your phases won't stay constant. Luckily this was found at the shop and we didn't waste any customer time. Regardless, it can be difficult to identify, but functional testing of your own equipment always helps to narrow down issues, before its a bigger issue. #NETA #NICET #electricalmaintenance #testing #electricalsafety #electricalengineering #electricalindustry #powerdistribution #powertransmission #testingservices #training #teaching #electrical #team #tech #lovewhatyoudo

Earlier last month, I had the privilege to witness and assist with a Calibration of 1 x Flow meter with a Calibrations Technician from a Reputable Calibration Company. The master meter (MM) used was an Avery Hardoll – BM650, an industry standard used for calibration of working flow meters, where repeatability and reliability are essential. The meter under Test was a Total Control System (TCS) – 700 – 35SPA4AL, with the following flow rate ranges; Max Flow Rate = 1135 LPM Min Flow Rate = 113 LPM Firstly, the MM was sat parallel to the meter to be tested and respective flanges, fittings & Pressure Gauge were mounted onto the receiving and discharge ends of the MM. 2 x 3-inch, 3m hoses were connected from the discharge end of the meter under test to the inlet of the MM and from the MM’s discharge end into a tanker Truck. The tanker truck used had a 18,000 litres safe fill capacity (4 compartments x 4500Ltrs each). We did 6 runs of 1500Ltrs each, running at an average flow rate of 800 LPM, using up 2 compartments of the Tanker Truck (9000Ltrs). As per normal procedure, there should be a minimum of 3 Pre-Proving runs and if acceptance tolerance levels are out of range, the Prover of the meter under test needs to be adjusted to cater for the error incurred. The adjustments will continue (through Post Proving) until results from the runs indicate repeatability of results within the acceptance tolerance, then the Cal Tech can give a green light and pass the meter under calibration. Fortunately, for the meter we calibrated, after the first 3 pre-proving runs, all results were within the Acceptance Tolerance, thus, after 3 runs of 1500 LPM, the TCS 700 – 35SPA4AL flow meter was giving of the actual preset volume correctly and the average meter errors were within the accepted tolerance +/- 0.05%. With satisfaction that the existing meter was operating after the 3 pre – proving runs, we did additional 3 runs, and all passed as expected. #calibration #learninganddevelopment #experience

Being EASA certified by the Electrical Apparatus Service Association (EASA) means that a service center or technician has met the rigorous standards set by EASA for servicing and repairing electrical apparatus. EASA certification demonstrates a commitment to quality, reliability, and excellence in the electrical apparatus industry. Here are some key aspects of EASA certification: 1. Quality Assurance 2. Technical Expertise 3. Adherence to Standards 4. Access to Resources 5. Commitment to Continuous Improvement 6. Customer Confidence Overall, EASA certification is a mark of excellence in the electrical apparatus service industry, reflecting a commitment to superior service, technical proficiency, and continuous improvement. #COILTEC #coils #coil #electricmotors #rotorcoil #formcoils #statorcoil #armature #VacuumPressureImpregnation #VPI #ElPaso #ElPasoTx

📑 Sequence Control Mechanic (SCM) Star-Delta starters have control circuitry that typically consists of a timer, contactor, and overload relay. To reduce the starting current, the motor is initially connected in a star configuration when it first starts. After the DC motor runs effectively, the timer switches to delta configuration whenever the motor reaches a certain speed. Thermal overload relays can protect the motor if it consumes more current.  It is the first material to increase the trainee's familiarity with implementing and reading the electrical wiring, also known as implementation in industry.
