I apologize if this has been asked before. I did a quick search and couldn't find anything. I have a new 2352 (my first PID controller) and have wired it into an old kiln that I am using for glass annealing. I have set CO-1 to 350 and TO-1 to 10. As the temp in the kiln rises the SV starts dropping. The output to the elements stopped around 330 and the CV continued to drop. Any help is greatly appreciated. Thank you.
First of all, SYL-2352 and SYL-2352P are different PIDs. SYL-2352P has ramp soak. SYL-2352 doesn't.
SYL-2352P requires at least two steps programming. It will not work properly if you only program step 1. Based on your description, your C02 and T02 could be a very low number, so you will notice your CV would drop. You can check the programming examples at the last several pages of its full version manual.
If you want to heat up to 350 and hold there for 10s, here is an example:
C01 = 80, t01 = 5 //heat up from ambient to 350 in 5mins
C02 = 350, t02 = 10 //hold at 350 for 10mins
C03 = 350, t03 = -121 //stop the program
Thank you for the response. I will try setting the C02 to 350 an T02 to 10 min and see what the results are.
Setting a T0x to -121 is the shutoff command? How do you set the controller to just reach a set temp and run at that temp indefinitely?
Here is the manual link for SYL-2352P:
https://www.auberins.com/images/Manual/SYL-2352P%20Manual.pdf
Set the timer to -121 will stop the program. See section 6.2.9 on page 8 for special event.
If you want to hold at a certain temp, you can set the timer to 0 as hold. See section 6.2.6 on page 8.
Here is an example.
C01 = 80, t01 = 5 //heat up from ambient to 350 in 5mins
C02 = 350, t02 = 0 //indefinite hold at 350 forever.
If you don't want to control the ramp rate, you can also use SYL-2352 PID instead (not SYL-2352P). You can set it to 350 and it will hold at 350 forever. It will be easy to be programmed.
Thank you.
