What is that thing on the right side of the temperature transmitter?
Thread Content
What’s that on the right side? Is it a lightning protection module? How is it connected to the table body? The table header no longer displays data, but the remote transmission of data works normally. How should this issue be resolved?
The surge protector may be short-circuited or faulty； It is recommended to replace the surge protector and try again.
Is this surge connected in parallel or in series with the main circuit? If it malfunctions, will it affect the remote transmission of data?
Surge protector: You can check the power strip
How can one determine that a surge protector might be short-circuited? Personally, I think there’s a higher possibility of a fault in the temperature-sensitive display part.
After a surge short circuit, the current usually only flows through the surge before returning, which causes the transmitter/valve actuator to stop working.
When taken apart, it is indeed in parallel configuration; I just don’t understand how protection can be provided in this parallel setup I’m a beginner; I hope someone can help answer my questions.
I haven’t conducted specific research on this; under normal conditions it exhibits high impedance. When connected in parallel in the circuit, the instruments function properly, which means there is no current shunting； When struck by a direct lightning strike, the large current generated under high voltage is rapidly discharged to the ground through surges, thereby protecting the equipment on site. Typically, surge guards are also installed indoors to protect the card slots.
