ph programming RAH

[nico62]

hello,

I has a profilux 2 plus Ex I would have more information on programming with respect to the ph

I want activate taking the powerbar when the PH decrease to a certain value and cut when the pH rises to the desired value

I want to have my ph 8.1 with a hysterisis of + - 0.2

Can you give me the programming please

thank you

Nico

enter the desired value and the hysteresis in the pH-settings

assign a socket with the function "pH 1 control upwards"

see manual for details

[nico62]

ok thank you

With this program taking the assigned powerbar will be triggered when the ph to hytérisis down and cut when it has atteitn high value hytérisis?

I take this post to do the same thing with the temperature probe.
should do the same manipulation with the program ph?

for temperature the settings are very similar:

enter the desired value and the hysteresis in the temp-settings

assign a socket with the function "temp 1 heating (resp. cooling)"

Thank you for your answers but still I do not have the options you give me in my controlprofilux

I for ph: Decrease Increase
For T °: healer chealer PTC

What should I choose?

My firware is 5.06t Version

Perhaps a screenshot of the settings in my PLC will help:

ok thank you

Decrease in choosing the pump will trigger when the ph will drop below the value set and cut when the value of PH goes to its high value?

When is it for the temperature? which option to choose?

Thank you in advance

No, it's the other way round. What you describe would be "Increase".

It is described in detail in our manual, please note:

"Control downwards
The control uses this switching output for the downwards-regulation e.g. to decrease the pH-value.
Control upwards
The control uses this switching output for the upwards-regulation to e.g. increase
the pH-value."

Please have a look again at our chapter "Switching output" in the manual, here the
functions for temperature are also described.
