New line of K type thermocouple controllers

[kayl]

well we carefully followed the instructions you sent ...
can you tell me what im doing wrong for this crap to happen?

seems to be the same issue i had with the Xe1.2 and also the value controllers.


Seems when compressor starts the initial current draw sends out EMI and this effects the controller. either getting in on the LCD ribbon cable of interfering with the controller physically.

I was able to work around this by manually starting the compressor first, then starting the gfroster. I was able to get all the controllers working this way. I still get errors though every now and again, also controller tripping and just shutting down.

read this link has more infor on my finidings, might help

Try shielding the controller ,ribbon and any wires in a brass wire "cage" that is grounded, built out of fine copper wire mesh.

I really haven't been following the circuits,so I can't comment. the cage will stop any EMF problems. yes ,compressors produce EMF especially at start up.you may be experiencing Back-EMF also.

you can see this in a oscilloscope if you have one.

ok, ill put the unit in 1 room and the controller in another room, maybe that will work

Did you insulated the k type probe? it needs to be insulated.

Golden released a new firm update.
Send me your email and I mail it to you.

BTW, keep crossing 220v cables over the controller, solenoids, etc, why don't you also do a permanent short circuit too...
I want to help, I have one xe 2.0 working for more than 2 month without any of that simptons, the only thing was some glitches on screen for some moments, so, Golden installed it and it works, he is not a magician...

Same on the value, I sent 6 to Kayl, he didn't make them work, but he sent one to Blank.God and he got it working fine, so, I think it has to be also with whom is installing it and in wich way.
We installed a value in a new unit last week, first run, flawless, I did several restarts, forced critical shut downs, and it keeps working fine, so, definitely has to do also with the way the controller is installed.

strange characters happens also to me, with value and xe 1.2..you can solve by let the connection cable between lcd and froster, pass away from compressor..

[Ssilencer]

Ssilencer - How is Golden driving the LCD? Direct from port pins?

Something simple such as a 74HC14 on the data lines may solve the problem...

yes I think so.
I will tell him, thanks, I will be back to you with an answer.

What he did now is clean the firmware of the cascade from the restart routine he made and use the function included in the display for software shut off, and the cascade is working flawless, after that, he released a new firm update that I sent to one of my local customers to be tested, and that also solved the problem in the XE 2.0, for the last 48hs my customer didn't had a glitch on display, so, looks like he found a fix.

Also RUNMC got the firm update, and he told me that it is working fine.
He had a problem but it was solved as soon as we explained better than just put a line in the installation pdf.

THE K TYPE PROBES HAS TO BE INSULATED ON THE PART THAT MAKES CONTACT WITH THE EVAP OR WHEREVER YOU PUT THE PROBE, A PIECE OF HEAT SHRINK, OR EVEN LIQUID ELECTRICAL TAPE WILL DO THE JOB, DO NOT PUT THE PROBE IN DIRECT CONTACT WITH THE SURFACE YOU WANT TO SENSE.

SHORT THE K TYPE PROBE INPUTS YOUR ARE NOT USING WITH THE PIECE OF METAL CLIP THAT COMES IN THE K TYPE PLUGS OR ANY PIECE OF METAL CLIP.

Don't forget to mention the fact that the positive wire (yellow) and negative (red) of the probe, must be pluged into the socket according to the + and - symbols on the diagram or you will get a bogus reading on the display.

At the moment, my XE2.0 is working good. I haven't installed it in the case yet. It is spread out on my workbench. It does seem that the XE2.0 is headed in the right direction. However I do know of one person who is having problems. Hopefully these problems can be worked out.

You're right
Did you loaded the new firmware?

It is loaded and working well - I am testing as we speak and I will continue to test and report back.

Ssilencer we would like to have Golden Froster Value 2.0 with K-Type and USB port

Best Regards

Lol!
I will take a Runmc advice, stop making new controllers until we get what we have in a mature enough state.
Yes, it would be nice, I was already thinking about only make k type controllers, if so, a value K type will appear, anyway, I was talking ro golden about serial to usb adapters because some guy asked for that, and golden said that any adapter will work almost for sure.

NEW SHIELDED DISPLAY CABLES



Feedback on the cables:

Now just have to finish installing the Gfroster XE2 and the cascade ready to bench

Yeah was speaking with sscilencer on MSN and he said to do that, which i did



Will do horri, i think the new atomic writer Moloko will enjoy the unit for a few months after the event before sending it back to me
Will have to build another cascade in the mean time for me to bench with.

Hey Fhqwhgads6680, this is my second professional cascade, but I have been making getto cascades for the last 2 years. Green is my favourite sleeving also, looks good on my bench cascade I think the controller finishes the cascade though.

You bugger, once I set the pc up on top of the cascade ill have to change the text menus Yeah I was up to 2am last night finishing it all off and putting it all together. I also installed the gfroster XE1.6 into another unit I have here, no issues this time round with bad character display, or tripping on start-up.
The XE 2.0 K type thermocouple controller works perfect in my cascade. The cascade controller didn’t quiet do what I needed (no windows software)
I have set the cascade so that once the first stage compressor reaches -25c 30cm before the compressor the second stage compressor starts. I also have a High pressure cutoff on the second stage. If first stage 30cm before the compressor ever gets warmer than -25c the second stage will shut down.
I also have a switch on the second stage to turn it off if need, will come in handy with benching. With the XE 2.0 windows software ill be able to do some nice window dumps for benching, look good on HWBOT.

Does the sheilded cable solve the problems with earlier models? I have some leftovers I would like to salvage if possible. I don't have LCDs anymore. I gave them to Reggie to try and help him out.

[Duh]

the balck version looks very nice

[Ssilencer]

the balck version looks very nice

Thanks
The XE 2.0, X3 and Cascade controllers always had black PCBs

Yes, we are making all the controllers with shielded cables now.

(along with a custom made cartridge heater for our next proyect...)

Aww no, I was just getting some designs together for that project - Looks like I'm going to be beaten to it. :c Probably for the best anyway, CE certification and all that to get a mains powered product looks nasty.

We got it on the freezer for a while, so if you want to join forces, you're welcome
