Carel temperature controller issues

[tegwin]

Hope someone can help...

I bought a pair of basic Carel temperature controllers from RS along with a pair of the recomended thermistors...

RS part numbers:
Controller 466-2012
Temperature probe 250-0158

I have wired up a 230V supply and the temperature probes to the two controllers and switched it on....

Both Carel controllers show E0 Which is a probe error code...



Does anyone have any experience with these controlers? Is there anything you have to do to make them work for the first time?

Or are the controlers/probes likley to be duff? (I cant belive both controlers and both sensors are FUBAR!)

most likely ambiant probe sensor.

What type of controller is it? The Carel type, RS doesn't mean anything to me!

Hi and welcome.

I'm afraid that you have bought the wrong probes.

That model unit uses PTC probes and you have NTC.

Sorry.

[Lowrider]

did a search on google, should be PJ32V6E000.

Manual could be found at: http://www.carel.com/carelcom/web/en...=5&id_gamma=18

Good Luck!

The controler is a Carel PJ32 V6E

230V
Single temperature probe (S1)
SPST 8A relay

Hmm...I have a NTC temperature probes.....one of the two spec sheets I have says it wants PTC (the other says NTC)

Thats silly...It also says on the RS website that either probe will work...ARGH!!!

Whats the difference, and could this be my problem?

[Lowrider]

The link I send is for the manual, which clearly ststed the unit you use needs ptc's.

NTC means negative temperature coëfficient
PTC means positive temperature coëfficient

On a NTC the resistance drops on increasing temperature, on a PTC the resistance goes up with the temperature.

E0 means S1 probe not working!

How annoying!

Looks like I will have to order a pair of new probes that actually work...Anyone want a pair of slightly used NTC probes :-(

Speak to RS and explain the confusion, they will take them back and after 6 months to a year you will get a credit note.

Most Carel controllers accept both, you only have to alter the parameter
If you have a small resistor of 1 kohm (PTC) and 10 kohm (NTC) instead of the regular probe, you can check your controller

[careluk]

Reading at previous reply to your query I can confirm the PJ32V6E000 (carel part number) accepts only PTC 1K ohm probe.
Unfortunately you have got the NTC type.
