Help with PID

[thepatchworkdoll]

Hi Guys anyone help with the setting up of my PID controller (http://www.ebay.co.uk/itm/PID-DIGITAL-T ... 2c7789883f). Wired up as per instructions but cannot for the life of me manage to set it up. Any offers really appreciated.

Your link doesn't work, but assuming it is a normal sestos type pid. What is happening when you power up? Do you get any reading? Do you have the right temp probe for your unit? Is it a ssr or relay type pid? What is the product code?

http://www.ebay.co.uk/itm/PID-DIGITAL-T ... a718cSorry that link did not work. Try this one hopefully. Yes I get reading. Bottom line can be altered up or down. top line has a -170 or thereabouts. cant seem to adjust top line reading even when the thermocouples in the water

Hi,

what type temperature probe are you using?
Some types of PID's like the Sestos can be set for different probes ie. k-type, pt100 etc.
If the PID is set up for the incorrect type of probe you would get a wrong reading.
I don't have any experience of the PID you link to, though.
Also, the bottom display is usually the "set" value (SV) and the upper display is the actual reading of the temperature probe, ie. the PV.

patch see my reply on jims.I put link to manual
if it is a k type the setting is not the same as for a pt100
if k type set Inty=k
if pt100 Inty=P10.0

 

[london_lhr]

if k type set Inty=k
if pt100 Inty=P10.0

The setting of the type of temperature probe is rather important.

Good luck :

Barry.
