Common Problem and Solved any Transmitter | Troubleshooting of Transmitter | PT | LT | FT | DPT | TT
Summary
TLDRIn this video, the speaker demonstrates how to troubleshoot a malfunctioning industrial transmitter, focusing on common issues like power supply problems and faulty fuses. The process involves checking voltage levels, inspecting connections, and replacing a damaged fuse. After the fix, the transmitter is powered on, and proper functionality is restored. The video emphasizes that issues like loose connections or blown fuses are often the root causes of transmitter failure. For further troubleshooting, the speaker suggests checking the display card. The video offers valuable insights for technicians and engineers working with transmitters in industrial settings.
Takeaways
- 😀 The video provides troubleshooting tips for a common transmitter issue where it stops working, often due to power or fuse problems.
- 🔋 Always check the voltage supply first when a transmitter is not powering on. A low voltage (e.g., 3-4V instead of 24V) is a strong indicator of the issue.
- 🔌 Inspect all wiring and connections for loose or broken links, which can prevent the transmitter from functioning properly.
- 🔧 Use a multimeter to measure the voltage and check if the transmitter is receiving proper power. This is crucial before moving on to more complex diagnoses.
- ⚡ A blown fuse is a common cause of power failure in transmitters. If the fuse is faulty, the transmitter won’t turn on despite receiving voltage.
- 🛠️ To diagnose a blown fuse, check the fuse with a multimeter for continuity. If there's no continuity, the fuse needs to be replaced.
- 🔄 After replacing a blown fuse, always verify the transmitter is working by checking the power and the display.
- ⚙️ Regularly check the display card in case the issue is related to the transmitter's display not showing any output, even if the power seems fine.
- 📝 The process of troubleshooting should include examining both the transmitter and its connected components, such as the PLC and control panel.
- 🎥 The video provides a hands-on demonstration of troubleshooting and encourages viewers to subscribe for more helpful videos and tips on transmitter maintenance.
Q & A
What is the first step when troubleshooting a transmitter that has stopped working?
-The first step is to check if the transmitter is receiving the correct voltage. Using a multimeter, measure the voltage at the back of the transmitter to ensure it matches the required 24V DC.
What is a common cause for a transmitter to stop working?
-A common cause is a blown fuse, which can prevent the transmitter from powering on. Checking and replacing the fuse can often resolve the issue.
How do you test the fuse of the transmitter?
-To test the fuse, remove it and use a multimeter to check for continuity. If the fuse does not show continuity, it is blown and needs to be replaced.
What should you do if the voltage is not correct, and the transmitter is not turning on?
-If the voltage is incorrect, first check for any loose or broken connections. Ensure all cables are securely attached to prevent voltage drops or interruptions.
What voltage is required for the transmitter to function correctly?
-The transmitter requires 24V DC to operate properly. Any deviation from this voltage can lead to malfunctioning or failure to turn on.
Why is it important to check the power connections and cables?
-It is important because loose or damaged connections can cause voltage issues, preventing the transmitter from powering on. Ensuring all connections are secure is essential for proper function.
What should be done if replacing the fuse does not solve the issue?
-If replacing the fuse does not resolve the problem, it is recommended to check the display card. A faulty display card could be the reason the transmitter is not displaying any information.
How can you confirm that the transmitter is now receiving the correct voltage?
-After addressing any issues, check the voltage with a multimeter to confirm it is around 22.3V DC, which is acceptable for the transmitter to work.
What is the purpose of using a multimeter during troubleshooting?
-A multimeter is used to measure the voltage at various points, ensuring the transmitter is receiving the proper voltage. It is also used to check continuity in components like fuses and connections.
What are some other common issues that might cause a transmitter to fail?
-Other common issues include loose wiring, faulty connections, and damaged components such as the display card or internal circuitry. Regular maintenance and checks can help prevent these problems.
