MYPIN TA4 PID manual, programming instructions and general PID/SSR info - by request
Mavrik - I also suggested using a couple of batteries in series to trigger the SSR, just to try to isolate the problem. If you can do that, disconnect the control side of the SSR, and connect a battery source (check the specification for the on voltage for the SSR - you need to apply that to...- btberlin

Mavrik Sorry - i misunderstood what you were getting at. If I recall correctly (I am not at home, and can't check directly), the AL1 output is also a low-voltage control output that would trigger an SSR. So, you could hook the SSR to that temporarily and see if it fires when the set point is...- btberlin

To Mavrik - additional info - add to my last post a few minutes ago. This is from Wikipedia: A solid-state relay (SSR) is an electronic switching device that switches states when an external voltage is applied along its n-type and p-type junctions. SSR has a small control signal that controls...- btberlin

I think that taking a look at the Wikipedia article about PID controllers may help you understand better. The SSR is NOT a proportional device - it is like a binary switch which is either on or off. Once the on threshold voltage is reached on an SSR, on the control side, the switched side...- btberlin

MYPIN TA4 PID manual, programming instructions and general PID/SSR info - by request
I am actually reading the legend on the front of the controller incorrectly. The "PV" legend is meant to be for the row of large LEDs above the legend, and the "SV" legend for the row of smaller LED's below. So, yes, the PV is the process variable, or in my case the temperature at the TC...- btberlin

I'm afraid I am not convinced by your explanation, so perhaps you can clarify better. On the MyPin TA4 controller, there is a large digital display of the measured temperature, which you are describing as the process value or PV. What was questioned in the part of this thread that I replied...- btberlin

If you Google" PID controller PV" you will find a wikipedia article that explains how PID controllers work. Here is a small snip from the explanation about PV, which is the value that changes rapidly when you press the set key on thr MyPin controller. A process variable, process value...- btberlin
