Zisterne Füllstand

[Warichet]

Caught in action !

Of cause, you must specify the ordered 16m in the converter. Then it is working perfectly: If you multiply all measured values with 16/14=1,14 you have almost exactly the wanted values.

Ok, I'll do my homework again.
If I understand well, an alternative could be to specify the "Upper measuring limit in x % from the upper limit of effective range", i.e. that is: 14m is 87,5% of the max (16m)
Right ?

For the empty pit: Move to Germany, then you won't have *this* problem

Well, I just moved to France
I know Germany for having worked there many times. Besides the wheather (no thanks) I also remember the "Apfelwein" ... ouch

[Warichet]

I'd give it a try with the proposed cabeling.

So, I've re-done my homework.
Your proposed cabling works fine.
One thing I noticed with your cabling, the AE/A is almost immediately operational after switching on the PS (as opposed to a delay of several minutes before.)

I guess, you adjusted the values for minimum, maximum etc. for calibration ?

After having set the max value to 16m in ETS.... here are the readings from 0 to 4m

 
Read - Meas - Diff
4        4    0
2,96     3    0,04
2        2    0
0,96     1    0,04

NB: The small differences might be due to my measuring method not beeing acurate enough. Anyway, I'm confident to drop the thing in the pit.

Thank you for having spend some time looking at this post.

PS: I've still an open question, which I submitted to ABB's TechSup, about the way to use the treshold 1&2, upper&lower limit. Seems it's not possible to set a fractional value there , only integers. Heck, makes a difference, between 1 & 2, that's 1.368L in my case. If I had a "zisterne" of 4m, those parameters would be unusable. I have only the german version of the doc, so I'm not quite sure of my understanding.

Fine. Now the probe is working, finally .

If it wouldn't be you and the german manual version, I would give you a RTFM . But tha't unfair, I know.

Here is the solution: If 136,8L are exact enough, simply set the "factor for output threshold" to "0,1" in combination with "Output value for upper limit" to "140". You will get the same values in the KO as before, but a change of "1" in the threshold will be 10cm in fact. If you want your threshold between 1,4 and 1,5m, you would have to enter "14" and "15" as tolerance band settings.

If you need a higher resolution, you will have to use your HS.
Either make the threshold part with logic there, or use it for "offsetting" your values, as the AE/S still would switch your pump, independing of a working HS (and if the HS is offline: there is no need of a values for the visu...):

The settings for the output values are limited -1000 .. 1000. If you set the factor to "0,01", you won't be able to get more than 10m (but a resolution of 13,68L at threshold). What you can do is to set the lower output value to (let's say) -400 and the upper to +1000.
An empty pit will give you "-4m" instead of "0m" and a completly filled pit "+10m" instead of the expected "14m". A simple addition in the HS can compensate for this, you could still use the threshold mechanism in the AE/S to check for limits. According to the above example of 1,4 and 1,5m, you would have to set the threshold parameters to -400 + 140 = -260 and -400 + 150 = -250.

BTW: "Apfelwein": Which region of Germany, has it been Hessen ? What cities in the neighborhood ?

[Warichet]

If it wouldn't be you and the german manual version, I would give you a RTFM .

You are too nice with the dummies

If you want your threshold between 1,4 and 1,5m, you would have to enter "14" and "15" as tolerance band settings.

ûûh, clever and all this in the manual

If you need a higher resolution, you will have to use your HS.
Either make the threshold part with logic there, or use it for "offsetting" your values, as the AE/S still would switch your pump, independing of a working HS.

Great, thank you for the tip.

The settings for the output values are limited -1000 .. 1000. If you set the factor to "0,01", you won't be able to get more than 10m .

Guess what, if you hadn't told me, I'd have tried that alternative .... just to bump into the limitation you mention.

A resolution of 136L is fine for a domestic usage, so I'll keep it simple .

As an aside .... I want to display the status of the AE/A in clear text in the Visu. I've already done something similar for a thermostat, using a Baustein "1 Byte to 8 bit" and then assigning the appropriate text to each bit. A bit clumsy, not very elegant. Do you know such a Baustein ? I haven't seen it, I guess I've to write it.

"Apfelwein": Which region of Germany

Rödelheim, west side of FFM

Regarding the status-display, I use a Kurvenfunktion (2Punkte) E1 your value in meters then 0,0,14(your max. height),100(%) or adjust the minimum as needed (I did this as I cannot use the last 30cm with the pump.

Durch den anderen Thread habe ich da mal wieder gelesen. Wenn das Filterthema noch ungelöst ist, dann meine - nach der Installation des Sensors zugegebenermassen das erste mal in Augenschein genommene - Zisternenlösung.

Da ich das Wasser nutze für
* Gartn
* Waschmaschine
* Toiletten

habe ich mich entschlossen, das ungefiltert zu tun. Die einzige und meiner Meinung nach gute Filterung ist bei mir Schwerkraftabhängig.

Meine Wasserentnahme findet ca. 10 CM unter der Oberfläche statt, das Grobsieb hängt an einem Schwimmer. Die Schwebstoffe setzen sich nach unten ab, so ist das relativ sauber. Die Pumpe wurschtet alles angesaugte durch. Mal nachgesehen, ist auf der WILO - HP ordentlich beschrieben und abgebildet.

Nach 2 Jahre habe ich jetzt mittels eines Wassersaugers die abgelagerten Schwebstoffe mal rausgesaugt, das wars.

Übrigens, bevor einer da auf schlechte Gedanken kommt, meine weißen hemden sind noch Blütenweiss, mit Ausnahme der Tomatensauce, aber für die kann ja die Zisterne nix. ;-)

[arosy]

Moin,
kann mir hier mal bitte einer die Tomaten von den Klüsen nehmen?

Weder hier im Forum noch bei Prignitz finde/sehe ich etwas von der Ader Belegung bei dem Sensor.

Bei

weiß = GND
braun = 24V
gelb/gruen = Sensor

bekomme ich keine Werte und zum zerschiessen ist mir das Ding etwas zu teuer.

[Warichet]

weiß = GND
braun = 24V
gelb/gruen = Sensor

ûûh
My Prignitz connection

Prignitz white -> +24V DC power supply
Prignitz brown -> A of the A/D converter (in my case ABB AE/A 2.1)
Prignitz gelb/gruen, not connected

ABB AE/A 0V -> -24V DC power supply

So, the sensor & the AD converter are serial with the power supply

[arosy]

Prignitz white -> +24V DC power supply
Prignitz brown -> A of the A/D converter (in my case ABB AE/A 2.1)

Thanks, there is a real Response.

Prignitz gelb/gruen, not connected

But now there's a litle bit confusion. Why does this is a three wire version?

[Warichet]

Thanks, there is a real Response.

OK, can you send me the "Tomaten" please

Why does this is a three wire version?

If you look at the sensor itself, at the bottom, there is a small label with tiny writing for the connexion.
But you are right, they could include a piece of paper with the minimum details for installation.

Hallo,

ich habe heute meine Pegelsonde von Prignitz erhalten.
Mich würde jetzt intressieren, ob ihr ein zusätzliches Gewicht angebracht habt, das die Sonde nach unten zieht?
Angeschloßen wird braun und weiß?

Gruß
Markus

[Hilli]

Hallo Markus,

nachdem die Sonde ansich schon nicht so leicht ist habe ich die einfach ohne zusätzliches Gewicht reingehängt! Funktioniert seit längerem super, ohne ausfälle!

Gruß Jochen

[Hilli]

Sorry ich vergaß, richtig angeschlossen wird braun / weiß!

Jochen

[Markus73]

Danke, für deinen Beitrag.

Gruß
Markus

[TRex]

die sonde liegt bei mir auf dem Zisternenboden, ist wichtig, daß sie ganz absinkt. Ein extra Gewicht braucht das nicht!
