I'm feeling pretty stuPID. PID wiring help needed.
« on: February 04, 2012, 08:28:24 pm »
I'm just going to throw this out there.  Not trying to sound like I want somebody to do this for me, but I'm not the best with electronics like these.  I have a REX-C100 controller with a K type thermocouple.  The instructions that came with it, show me nothing about how to wire it.  So I had to kind of make sense of it myself.  And I think something is wrong.  And the instructions from the manufacturer site are misleading.  Because the terminals aren't in the same location as the label on the actual controller.  So I'm hoping somebody could just tell me what to put where. 

Also, I can't seem to get it to convert to Fahrenheit, by following the instructions given.  Probably due to my lack of understanding.

The different manufacturer's instructions are here http://www.rkcinst.com/english/pdf_manual/imnzc21e1.pdf.

And the way I have it wired is pictured.

Thanks for any help.

Dave,

The manual http://www.rkcinst.com/english/pdf_manual/imnzc21e1.pdf on the top of page three shows how to wire a REX-c100 PID.

I don't know very much about temp controllers but if you have some question I'll try to help.

Also found this manual http://www.fmfranklin.com.au/products/data/rkc/c100inst.pdf.

You can't put it on the internet if it isn't true!

Hi Doug.  Thanks for the reply.  I've looked it over, and understand that much.  I know where the power goes in, where the thermocouple goes, and the alarm, but I'm trying to figure out mainly how to wire in the relay with the heater cartridge.  If I match up the relay with the relay picture on the control, nothing will happen.  It'll just be a mirror.  I'm wondering if somebody has a burner kit from CK Burners.  Since that is pretty much the siphon system I'm trying to mimic.   :-\

Dave,

 Not sure which relay you have but heres how mine is wired. Number 3 is switched 110vac positive from aquastst and 5 is the neutral 110. Number 1 terminal on relay is connected to the number 5 PID terminal. Number 4 of the relay goes to the heater cartridge.
  
I hope this helps.

OK I think I got it.  I had a missing wire.  #2 to #3.  But the thing gets hot fast.  And I can only see it in centigrade, so I'm trying to convert it at the same time.  I've heard some not so great reviews about this particular PID, so I might get another one.  Thanks for the help.
