Resetting a Fuji PXR3 to factory settings

by **703Eric** on Mon Jun 16, 2008 5:18 pm

Hi, Does anyone know how to reset a Fuji PXR3 to factory settings? I just installed a PID unit on a linea and I think I messed the programming up.
Thank you,
Eric

You may want to try an AutoTune as a place to start. Start the AutoTune @ ~ 180 to 200°F

have set all the parameters and double checked them but the brew boiler will not stop heating. it hits the CV value and just keeps going up.

I just tried to do Auto Tune but if just keeps heating past my High value. I would like to reset the PID to the factory setting and start again.

Have you've verified the SSR is ok by disconnecting the DC control from the PID?

Thanks for your help Ike, How can i check the SSR by disconnecting the Power to the PID? Sorry, I am a bit of an electronics idiot.

Oh...

The output of the PID is normally a DC voltage that is fed to the DC side of the SSR.

The RED wire, connected to +, is the one you need to lift.

If you remove the control input from the SSR, the machine should stay cool. If the SSR is blown closed, an unusual failure, the machine will heat regardless.

Is it possible that you have the SSR control wired to the wrong terminal and it's always on?

Just disconnected the red wire from A1+ on the SSR to position 5 on the Controller and the boiler keeps heating

Ok. Leave that disconnected.

Remove AND INSULATE / ISOLATE one of the A/C leads to the SSR.

What model SSR are you using?

BTW, DEBUG :?:

UNPLUG

Its a Carlo Gavazzi from Espresso Parts

Does it have a model and rating?

by **703Eric** on Mon Jun 16, 2008 7:19 pm

Model- RS1A23D25 AC51: 25A 240V 3-32V
THANK YOU SOOOO MUCH FOR YOUR HELP!

by **cafeIKE** on Mon Jun 16, 2008 7:23 pm

Seems OK by the rating.

What happened when you removed one of the Line inputs to the SSR?

by **703Eric** on Mon Jun 16, 2008 7:26 pm

Steam boiler started to heat, brew boiler was dead

by **703Eric** on Mon Jun 16, 2008 7:27 pm

Do you think that I may have a bad SSR?

by **cafeIKE** on Mon Jun 16, 2008 7:34 pm

Did you notice if the LED on the SSR went off as the boiler neared the CV?
Did you notice if the C1 / C2 lights went off as the boiler neared the CV?

by **703Eric** on Mon Jun 16, 2008 7:36 pm

Once I removed one of the AC wires the light never turned on. When I had everything hooked up, the green light would blink slowly

by **703Eric** on Mon Jun 16, 2008 7:38 pm

The green light would continue blinking as the temp. passed the CV

by **703Eric** on Mon Jun 16, 2008 7:39 pm

I have had such a bad time with this controller that i am thinking about putting my Thermostat back in. :cry:

by **cafeIKE** on Mon Jun 16, 2008 7:52 pm

By Green Light you mean the LED on the SSR or the C1 / C2 LEDs on the PXR3?
