JLD634 program example

Postby Juniorbarns » Tue May 10, 2011 8:05 am

I previously purchased the JLD612. Fairly easy to set up using the manual.
Then purchased the JLD634. This one not so easy as Marco has stated in previous post.
Can anyone offer a simple example program that includes a ramp and soak step??

I would like to ramp to 212 F from ambient and hold for 15 minutes then ramp to 318 F and hold for 25 minutes then ramp back down to 212 F and hold for 15 minutes.

Ramp time is not important except to say the quicker the better.
I assume if a selected time for ramp is too short based on heating capabilities the program would "hold" until temp is attained.

Any help would be greatly appreciated!!

Thanks

Hello Juniorbarns:

This is Marco. I tried it and got some experience of the JLD634. After a couple try, I know a little bit about this meter. It's not as difficult as it was. I'll post a simple sample here later. Remember, the JLD634 is a 'dual' type controller, it can do PV and Ramp/Soak. So, you got to let it know the 1st time or it won't do work as you expect. It's a little confuse the 1st time, but once you got your hands on, you will love it. It's so powerful!

Marco

Thanks Marco.
Eagerly waiting for your example.
From what I have been read into, I agree it is quite a powerful Gem.
As I learn more, I will try to share as much as i can to the group.
Thanks again.

Before doing programming on the JLD633 or JLD634, there are couple things you need to decided what to do with.

1) Selecting working mode: SV, S-SV, M-SV, S-PV, M-PV
(this can be done by password "0089") and the setting is by "ModL", the symbol is a '-' over n
SV = regular temperature control like the JLD612 (no ramp, no soak)
S-SV = time domain and in seconds
M-SV = time domain and in minutes
S-PV = temperature domain and in seconds
M-PV = temperature domain and in minutes

Time domian means that the controller will jump to next step as time closed by and ignore the value of PV
Temperature domain means that the controller will jump to next step only when temperature reached the SV

I want to try the Ramp so I use "S-SV" as I don't have a heating element connected so I have to use time domain to simulate the process.

2) To enable realy J1 and J2 On and Off, use tX= -1011, -1010, -1021, -1020
where -1011 = J1 On and J1 Off if -1010
and -1021 = J2 On and J2 Off if -1020


I used K type for my sample so I set Inty as "K". Look the symbol is a revesed of digital number "4"

To configure the Ramp, I enter password "2000"

Let' say I want to start from 50'C and heat up to 85'C in 10s and use PID setting group '1'
So, I set

C-01= 0, sv01 = 50, t-01=10 (where C-01=0 the "0" means PID group 1)
C-02= 0, sv02 = 85, t-02=20 (and, I want to keep 85'C for 20s)

C-03= 0, sv03 = 85, t-03=-1011 (relay J1 is On as I use t-03=-1011)

Then I want to heat up to 200'C in 60's

C-04= 0, sv04=100, t-04 = 60
C-05= 0, sv05=200, t-05 = 20 (then I want to drop it to 100'C in 20s)

C-06 =0, sv06=100, t-06 = 0 (now I want to turn off the relay, so t-06=0)

C-07= 0, sv07= 100, t-07=-1010 (t=-1010 will turn off J1)

C-08= 0, sv08=100, t-08= 10 (10 seconds later, it will drop to 50'C)

C-09= 0, sv09= 50, t-09 = -2 (Then repeat the process from stage 2, so I set t-08 = -2)

Final step, enter "8888" to start the instruction from the beginning


Hope this help. The most confuse thing here is time period of the ramp. It always means the time it need to take from the current stage to the next stage. You need to use a piece of paper to drop the charge and write down the parameters one by one. When doing input on the controller, focus on the parameters name and number you punch in rather than thinking what is this and that as you already done so while doing that on paper.

There are some error on the code about. Relay couldn't be turned on and program couldn't repeat itself. I need to debug it. Stay tuned!

Update: Fixed alarm issue J1 issue. The action mode of the built-in relay must set to "00" for event triggering. I reset it for SV mode. That's why it didn't enable the J1 when I set t-X = -1011

But I still need to check why it won't repeat itself and now the J1 was On all time. I need a little more time for debugging...

Got it!!
The reason the controller couldn't repeat itself because I put the controller on 'pause' by setting t-X= 0. Now I set t-9=1 and it works. See the high light and bold text in red from my 1st post. Now the controller running as it should, repeating itself with J1 On and Off on time. (我太有才了) = I'm smart ha..ha...

Cheers!!

Found something good. Assuming I keep the t-x=0 (pause) and had the controller paused on line 6. How do we resume the operation? Ha, after tens trying for about an hour, it's simple:

Do this: Press ">" twice and you will see "S-06" blanking (S=segment), means that it's on pause now. Then, press Up arrow key and and procedure will jump to next one which is line 8 (note, line 7 is timeless it disable J1, so the screen will not display line 7 "S-07" but to S-08 instead). Then, the controller will finish the rest and repeat again and again and again... till you stop it.

I think the 'Pause' is a great feature when doing Ramp/Soak processing. Sometimes you may need to interrupt the process say, adding material to the kiln, adding fuel, or adding water... whatever it need to shop the process, the Pause is a great help. Once you completed the interrupt, you hit those two buttons to resume the heating/cooling again.

Make sense?

Mario,
This is great!
I believe I have enough information from your example to try my own now.
For my program, I will be using S-PV as my priority is to hit the desired temp as fast as the heaters will allow.

I do have a couple of questions that I hope you can clarify for me.

Your comment

"2) To enable realy J1 and J2 On and Off, use tX= -1011, -1010, -1021, -1020
where -1011 = J1 On and J1 Off if -1010
and -1021 = J2 On and J2 Off if -1020"

I am using a SSR only at this point but may want to use the relay outputs to serve a seperate function later on.
My question is, What program group did you set the relay perameters?
Was it in 0089 or 2000?

As you say in the end, it is prefered to wriite the ramp/soak sequence on paper first.
Much less confusing doing it this way.

Will comment back when if and when I am successful.

THANKS!!!

The relay works independently even with a SSR attached (my setup with a SSR attaced)

You use password "0036" to configure the AL1y and AL2y. Set it to "00" to event action, that will do the trick

Here is my setup and program.
Using P-100 TC

My desired temperature profile.
Begin at ambient (70 F) and ramp to 212 F and hold until I am ready to load my part into oven.
I will use Relay 1 for a yellow pilot light to indicate that 212 F preheat is achieved.
After part is loaded ramp to 318 F and hold for 15 minutes. (cure)
Will then use Relay 2 for a buzzer to tell me part is done.
Remove part and ramp down to Preheat temp of 212 and hold.
I will use the "skip to" command to start from the beginning.

Notes:
Per Marco's comments
Under password 0036, I set ALIy to value 00
Under password 0089, I set ModL to S-PV (all times in seconds and next step occurs when PV is achieved)
When choosing the to turn on or off the relays, the program will display a sideways "T" and then a "-" sign. Coose the sideways "T" symbol.
When choosing to skip to a previous step, choose the "-" symbol


T-01 = 1800, SV-01 = 70, C-01 = 0 Ramp from 70 F in 30 minutes to.......
T-02 = 0001, SV-02 = 212, C-02 = 0 212 F and wait 1 second then go to step 3
T-03 = -1011, SV-03 = 212, C-03 = 0 Turn on relay 1 and go to step 4
T-04 = 0000, SV-04 = 212, C-04 = 0 Pause at 212 F. Step 04 flashing. choose ^ to continue
T-05 = 0300, SV-05 = 212, C-05 = 0 Ramp from 212 F in 5 min. to .......
T-06 = 0001, SV-06 = 318, C-06 = 0 318 F and wait a second then go to step 7
T-07 = -1010, SV-07 = 318, C-07 = 0 Turn off relay 1 then step 8
T-08 = -1021, SV-08 = 318, C-08 = 0 Turn on Relay 2 then step 9
T-09 = 0900, SV-09 = 318, C-09 = 0 Hold at 318 F for 15 minutes then step 10
T-10 = 1020, SV-10 = 318, C-10 = 0 Turn off Relay 2 then step 11
T-11 = 0900, SV-11 = 318, C-11 = 0 Ramp from 318 down to........
T-12 = -002, SV-12 = 212, C-12 = 0 212 F and repeat from step 2

Marco,
Your information was great and I can't thank you enough.
The only problem I guess I have is when I ramp down in temperature, it does not wait until it achieves the desired lower temp.
Example: from step 11, my PV temp is 320. immediately after going to step 2 it proceeds on to 4 which is a pause at 212 and will get me there anyway but I would have expected a program hold at step 2 unitil I was at 212??

Thanks

Correction.
My last statement on the step not holding from going from a high temp to low temp is NOT true. It does hold the step until the lower temp is achieved.

I love this little unit.

Marco,
Can I use relays J1 and J2 to turn on SSR's?
The duty cycle is per the program so it will not be turning on and off rapidly like the main output for the heaters.

One more question.
Reading through the manual, is it accurate that Auto tuning is only permitted in SV mode?
Can I auto tune my program?

You can use J1 or J2 to control a SSR. Simply apply DC 5V~32V(depends on the SSR you have) and you need a seperate DC power.

Sample: route + 5V power to the COM of the J1 and has normally contact (N.O.) connected to the SSR + DC. Then route the 0V of the DC power to the (-) of the SSR. once J1 in action, N.O. becoming closed conatct and drive the SSR.

You can do Auto Tune on SV then copy those info back to the P.I.D grounp if that is the case that only SV support Auto Tune
