Your field wiring drawing (and cable lengths) would help sort through your problem

So you have described a coil circuit with the contact on the common wire. Sketch your circuit.

Just be patient,

Do what you enjoy and don't forget safety first, when as job pays more, they demand more.

The terms and conditions of the customer contract govern.

You might also review the ladder diagram of your circuit

your vendor typically has training seminars

Your knowledge of the electronics and the controllers, will help troubleshoot when things go bad with transmitters, sensors or final operators.

K Type Thermocouple probe short circuited with metallic body You need to show a picture of your T/C, and explain how you have attached the metal short to the t/C wires

your t/c supplier will show you

Just be patient, the opportunity will present it self. Automation is all about how the operators run the plant and keep it going, understanding the process is key to troubleshooting automation issues.

What is the purpose of the temperature measurement?

Develop the Bode plot (frequency response) of simple time delay circuit and you have your answer.

you need to show how you arrived at this transfer function

Your new board has some sort of grey paste around the base of the electrolytic capacitors. Is that intentional? Unusual for printed circuit boards. You might check the voltage across the electrolytic capacitors when powered. Then when with outpower, check their resistance with an ohm meter in...

With old compressors like that, the bearings get warn, and would not start only to blow the breaker and shutdown. Recognizing the motor/compressor was 20+ years old, after checking for shorts, the tech put in a larger starting capacitor and it ran. He mentioned, that we really needed a new...

Fluid composition solids content, etc., installation, including pipe size. Summary if issues encountered, and frequency of re-occurance. Please explain why you are seeking a retractable design, since inline measurement are used in the original design.
