This video teaches you how to program the PID ramp/soak kiln controller. It presents a simplistic way to understand how to program the controller, then goes through an example
Thank you for this video. I am trying to program this controller for my ceramic kiln. Unfortunately, it seems that the SV (set value) is following the program and keeps changing, but the PV stays the same. Do you have and idea what could be a problem? Thank you!
Confused.. time to reach temp in that segment, or time held at that peak temp for that segment. "Hold" is a term used to indicate a period when the temp doesn't change. Knowing the rate of climb (temp/hour) I would think more important..and is separate from a hold. Does this controller do both ramp and hold?
I just started using a PID-RS-S-48 controler with my kiln. But the controler stops midway and does not reach my SV of C1140. Is there an explanation for this? Is this a safety feature for too fast arise in temperature?
What does the time set for a temperature means? Is it the time the set temperature is held or the time to reach the set temperature? Also, are there any automatic stop features for safety?
I have hours invested in trying to get this controller to work. It will not even go back to c1, 20 I can't reset the input. There is so much stuff that I don't understand and I am not sure if this thing worked out of the box. right now the green LED is blinking AE and what looks like "pie" 100. How do I get back to C1?
I'm afraid that I don't know exactly what you're talking about. Try to hit "set". Then if now help I would give the customer support a holler. Thanks for your comment. Best wishes.
Benson, do you know maybe why my PV, even at room temperature, is always 25-30C higher? I'm not sure if it is due to my thermocouple as when I hold it in my hands, the PV value rises and falls normally. even though it won't fall below a certain threshold (I believe 15-20C) even when my room is near 0C. This kind of makes things difficult to program for the SV.
Not sure. You can change the offset temperature to compensate for erroneous results. The parameter you want to change is called SC. I'd give that a try. Hope that does the trick!
The usual cause of a difference that large is there is an offset programmed into the unit that should be removed, or the wrong type of thermocouple is selected. T v.s. K, for example.
my evenheat died today i had bought this controller in 2019 for another kiln i cannot find the manual online same model i want to reset factory defaults as i cannot remember how i had it working and then follow this video.any link to manual or how to reset...help help😓
Thank you for your videos they are very helpful but do you have a video describing how to just if the actual temperature is about 60 degrees higher than the set temperature.
Oh man. I'm sorry. I don't. Do you mean to adjust the temperature? I'm sure you don't mean to just do the arithmetic for each segment. That would be too easy!
@@bensonfilmworks7595 For example if I set the controller to go to 200 degrees the kilim will actually measure about 280 degrees, strangely if the program is not running the controller states that the temperature is 28 degrees and my other thermocouples and temp gages confirm 28 degrees also.
@@matteyles7466 There's an offset parameter you can change. Hit "set" repeatedly until you come to SC then enter the offset. Make sure you have the correct thermocouple type selected. This is called "Input type" abbreviated Sn in the menu! You might double check to make sure your selection matches your thermocouple. Hope this helps!
The "instructions" in the "manual" are essentially useless. They are inadequate, opaque and written in poor English. This unit has two completely different ways to to programmed. The method shown above and using what is called auto-tune which is far easier. The instructions in the video omit several steps if there is a soaking time. Here is an example of the planned cycle: Start at 25 C Heat over 20 minutes to 200 C Hold 200 C for 30 minutes Heat over 80 minutes to 1000 C Hold at 1000 C for 100 minutes Cool over 50 minutes to 500 C (which is -10 deg per minute) Turn off and cool naturally to ambient Settings C01 25 This is the initial temperature. You have to have one. It is Set Point 1. T01 20 This is the heating time to the next set point, not the time to get to the value 25. Many are confused by this. C02 200 This is the target temp of the second set point. The controller will take 20 minutes to get there, remember, the previous entry! T02 30 This is the time to get to the third set point. C03 200 This is the 3rd target temp which is the same as the last one, which means the temp will remain constant. This entry is missing from the video. T03 80 This is the time it will take to get to the next set point. C04 1000 This is the next set point. The controller will take 80 minutes to get to 1000 C. T04 100 This is the time it will take to get to the next set point, which is going to be the same, meaning, no change. C05 1000 This is the temperature of the soak and it will last for 100 minutes. It is the same as the previous set point, = SOAK. Not shown in the video. T05 50 This is the time it will take to get to the last set point. C06 500 This is the last set point which is cooler than the previous one. The controller will try to let it cool over 50 minutes, if it can. If not, it will take longer. T06 -121 This is a special code that means "End Program". After this point is reached, the kiln will turn off and cool naturally. The importance of step T5 and C6 is that the cooling rate might have to be quite slow in order not to crack the product from differential thermal contraction. The kiln itself may have a maximum cooking rate. Don't exceed it. More generally: Ramping from 200 to 1000 over 80 minutes (which is really fast): do not do that with a clay containing a lot of carbon. Usually you should wait at 105 or 120 C for an hour to dry the product which would require 4 additional entries between T01 and C02. A soak has two steps: both at the same temperature. The video misses these soaking steps. After drying, ramp at a rate of about 135 deg/hour up to ~620 then hold until the carbon burns out which might take 2 or 3 hours. Open the air holes for a small air flow during this time as carbon removal consumes oxygen O2 => 2CO. If you heat quickly and directly to 750 C it will melt the outside of the clay and trap the carbon inside. After getting out the carbon, you can ramp quickly to 950 or whatever the final temp is, at say, 250 C per hour. If the kiln cannot heat that quickly even if you set it to be that quick, it will take longer, then start the next step. Discussion of ramping is usually in terms of Degrees C per hour. This has to be recalculated into the temperature difference between steps and the minutes needed to get there at that heating or cooling rate. The Autotune function is completely different and more like what the video describes.
How do you create, store and name, and run a program any time in the future? It's not clear. The steps make sense, but I ain't grokin' the big picture. Is the example retained in memory even after it's turned off? Can you store several programs? The manual is a nightmare. All I want to do is make my 1970s era Paragon kiln go up to 1450F and stay there til I say "Down boy!"
The program remains in memory until it's replaced by another memory. Only one program at a time. Agree totally about the manual. So you would program the program something line this: First is ambient temperature. Next is the t (time) you need to get to the set temperature. Then you would put in a long time (hold time). Interrupt the program when you get tired of it being at that temperature. Let me know if you want step by step instructions. And thanks for watching!
@@bensonfilmworks7595 I figured it out for the most part, at least well enough to use my kiln, after reading 2 different manuals and watching your video along with another one. Thanks.
@@TheKrighter GREAT! You get a master's degree in kiln programming. Congratulations. I'm like you. Just know enough to limp along and get a simple program to run!
@@bensonfilmworks7595 Hey one more question: How do you turn a program off completely so you can start from the beginning? I keep restarting it and it starts where it left off, which is causing problems. I set 'run' to various settings but none of them work. Is there another parameter that sets all back to square one?
@@TheKrighter I know what you mean. I just completely unplug it from the -main power supply, wait half a minute and seems like everything is erased. As an aside, once the program is running it seems to keep running, picking up where it left off when the power is interrupted for a few minutes. Pretty cool

Are the degree numbers in Fahrenheit or Celsius?
Always centegrade. No way to change to fahrenheit

Move the sensor controlling the kiln. It is not getting the actual interior temp. Alternatively, lower your program temp. Easy.
