ATO using three sensors

[jimdoniom]

Hi can someone tell me what settings I should choose and/or have to make to have ATO operate with three sensors.
Sensor one as a low level sensor to turn ATO on , sensor two as a safety high level sensor to turn ATO off should a high level be reached and sensor three as a low level pump protection should the ro top up container run low on water.

I have tried to find details both in the manual and the programming guides but I can't find use of three in this way,and I am sorry but I don't understand what to do. So if someone could please post it up as a list, ie level one , choose ATO with two sensors, or choose max/min control, socket X set this as Water 1 or what ever it has to be.

Thanks

Can nobody help?

Can't you use this as a starting point ?

And just add your 3th sensor where it comes into play ?

I have looked at that, and yes some of it points me in the right direction , but all the screens i see on the software are now different and I do not know if it is correct. I just don't understand what the manual or the threads mean in some places without a step by step guide, as explained in the first post.
surely it is not too much to ask from a brand new user that someone can explain in simple steps what to do?

I think you should go step for step

first setup the ATO with 2 sensors
what to do:
1. set mode of level sensor 1 to "ATO with 2 sensors"
2. set the function of the socket in question to "water 1"

when this is working you should go to the next step

Hi Matthias

Thank you this is exactly what I want to do.

I have sensor one connected and it is working on it's own as ATO
I have set the socket No5 to water1

This is working OK with a setting of 3 seconds as the detection and ten seconds as the max pump time.

I would now like to set up the level 2 so that if the level 1 sensor sticks then it will turn off the pump at a max level.

Then if I understand it right I can add level 3, I think as an inverted function?
so that it can turn off the pump if the level in the RO container becomes too low?

[Matthias]

if you use "ATO with 2 sensors" sensor 2 will automatically have the backup function for sensor 1
-> then sensor 1 and sensor 2 determine the state of water 1 - nothing more to do, just use this mode

for the third sensor: use for level 3 mode "return pump"

after you did the above we can continue

[jimdoniom]

I have now done that the levels 1 and 2 appear to work correctly, and I have set level 3 up as return pump but I keep getting an alarm on level 3.

I'm not sure if I need to add something else maybe in programmable logic but I am lost again

Any help on the alarm issue?
I'm getting the same thing when I have level 2 as return pump?

Level 1 is ATO
Level 2 is Return pump
The states of both levels are behaving like they are suppose to...
