Pid d1s-vr-220

[vestjyskmikrobryg]

Hi

I have just bought a PID temperature controller D1S-VR-220http://sestos-hk.com/english/product_show.asp?productid=495 for my beer brewing kit including a pt100 sensor and solid state relay. All in one kit from Ebay.

I want to use the PID controller as an ON/off relay for the water heater to get the predefined temperature.


When I plug the pt100 sensor to the PID (plug 3 and 4) and choose pt100 (Sn=21) in the operation settings - then I get a flashing error saying "orAL". How can that be?

But if I set the "input senser" to K-type (Sn=0) then the PID can measure a temperature of approx 23-25deg Celcius. But not higher or lower.

I have made a small test setup with a normal kitchen boiler, where the water temp was approx 50degC, then the temperature (PV) on the PID showed only 24degC.

How can that happen and do anyone had that same problem.



Furhtermore do you know the difference between the three settings for the "control output":
0 = ON/OFF
3 = PID (Default setting)
2 = Auto adjustment

Do you also know the difference between the three settings for the "run" mode:
0 = Manual
1 = Automatic
2 = Inhibit manual (Default setting)

Hope you can help me......
Regards
Anders

Have a look at this thread and specifically the work done by mysobry & mredge73

From the Auber manual (basically it was assumed in the thread above the Sestos were Auber knockoffs)

8.1 Display orAL
This is an input error message. The possible reasons are: the sensor is not
connected correctly; the input setting is wrong type; or the sensor is defective.
In this case, the instrument terminates its control function automatically, and
the output value is fixed according to the parameter OUTL. If this happens
when using thermocouple sensor, you can short terminal 4 and 5 with a copper
wire. If the display shows ambient temperature, the thermocouple is defective.
If it still displays orAL, check the input setting, Sn, to make sure it is set to the
right thermocouple type. If the Sn setting is correct, the controller is defective.
For RTD sensors, check the input setting first because most controllers are
shipped with the input set for thermocouples. Then check the wiring. The two
red wires should be connected to terminals 3 and 4. The clear wire should be
connected to terminal 5.

I have my SESTOS up and running.
It is a knockoff of the Auber (or the Auber is a knockoff of the Sestos).
I was able to get it + thermocouple + SSR for about $40; Auber would have cost me $90+
I used the Auber manual since all the parameters nearly identical and it is written in English. The most obvious difference being that you have to learn to deal with Celsius since there is no way to change it.

The manual control works fine, it uses a control period measured in seconds that you can set and you manually put in what percentage of the control period that you want the element to stay on. Kind of like a PWM controller but with a long period. For example, if my control period is 120 seconds, if I set it to 50% then it will switch on for 60s then off for 60s, repeat.

The alarms are set up identical to the Auber as is everything else.

other notes:
The SSR works perfectly as does the K sensor that came with the unit. It didn't come with a heat sink but I think it will be fine since I am only using it for my RIMS tube. I installed it in a sealed waterproof J-box, I am worried about heat buildup so I am rethinking the design.

other thoughts:
I don't completely understand how to do the auto program function, neither manual really explains it well. I ran it with about 3 gal of water with a set point of 40C, took a few minutes to get up to temp but took 1.5H to complete the auto program. Should I have done this like a simulated brew day? 3-6 gal set up at 68C?

Hi
At the end of the day (after one month ) I received the parcel from Hong Kong with the bundle of Sestos PID controller+ K sensor + SSR 25A
The package was perfect, everything as listed on ebay and I have paid around 39USD including shipping (no custom duty !)

So I was very happy and I have tested the devices in order to understand the different behavior and features

I can confirm that the manual mode works fine…generally speaking you can combine
Control Output-> ON/OFF or PID (plus auto adjustment)
with
Run Mode -> Manual , Automatic, Inhibit manual

I have set the PID Output and tested different Run Mode

In manual mode you can set the percentage of power of the device regardless the temperature set value and present value…the SSR switch on and off with the percentage of the control period (that you can set from 0,5 to 120 s)
In Automatic Mode you can chose between the PID temperature control and manual control just pressing the AT key
In Inhibit manual you have just the temperature control

It’s interesting that if you are controlling the temperature you can alternatively display or the set value temperature or the percentage of power that is currently applied…this value is dynamic according to PID algorithm

Some picture shows better the different possibilities than my poor English!

Now I have to install and connect everything in my single vessel – braumeister colne application ..but I’m quite happy with the Sestos business

Give me a few months more I might be able to help you with actual experience with the Sestos (if I go the PID route )

Thanks for your reply.

I´ve coupled terminal 4 and 5, and apparently that solved the problem. Now it can measure the temperature and not only the ambient temperature.

Now I only have to fine-tune the setup. Is it normal that it is necesarry to calibrate the sonsor to measure the correct temperature. (calibration +/- 5 to 10 degC), or is it due to the setup of the PID values in the settings menu.

It is normal for the probe to have some error but (in my experience) it'd never more than a couple of degrees F. 5 to 10 degrees Celsius is a HUGE error.

one thing strikes me as odd. Your PT100 sensor only had 2 wires on it?

They normally have 3.

I have a Watlow96 controller. Granted it is a completely different controller but I think it likely operates similar in this matter. According to the manual:

"RTD input: Each 1 ohm of lead wire resistance can cause a +2F error when using a 2-wire RTD. A three-wire RTD sensor overcomes this problem. All three wires must have the same electrical resistance (i.e. same gauge, same length, multi-stranded or solid, same metal)."

Yes it only has two wires.

Just check the listing in my watchlist and it is - PID + K Thermocouple + 25A SSR. Do you have a link to the one you bought?

 

[vestjyskmikrobryg]

Now it works perfect when I coupled terminal 4 and 5.

Thanks all for your help. That saved me for a lot of time.....
