P4 - problem with multiple level sensors using Y splitter PL-LY

Greetings from Australia!

I have recently purchased a new Profilux4 along with a Powerboard 5.1, 2 optical and 2 float level sensors, a leak detector module and 2 sensors, and 2 Y-splitter cables (PL-LY).

The level and leak sensors work fine when plugged individually into the two level sensor ports (purple and green), however when I plug two sensors via the Y splitter they do not work properly and seem to require both sensors to be activated to trigger an action.

For example, if I plug one level sensor direct into the purple input and set up Control Circuit 1 to operate as a single-sensor ATO using sensor #1 and linked to Switch Channel 1, then socket 1 on the powerbar correctly activates when the sensor is in a triggered state, and turns off when the sensor is not in a triggered state. If I plug a 2nd sensor into the green input and set up a different Control Circuit using sensor #3 it also works fine, and it does not cause any problem to the functionality of Control Circuit 1.

However, I if use the PL-LY to plug two level sensors into the purple socket, Control Circuit 1 will not activate unless BOTH sensors are in a triggered state, and will not turn off until both sensors are untriggered.

Setting up two Control Circuits to use two sensors connected via the PL-LY (one using sensor #1 and the other using sensor #2), results in only Control Circuit 1 working when both sensors are triggered, and Control Circuit 2 not working at all.

The problem occurs regardless of which sensor/s or the leak detector module is used - if two sensors of any type or combination are plugged into either the green or purple ports using a PL-LY cable, nothing will work unless both those sensors are triggered at the same time.

I have tried all possible combinations of sensors on both PL-LY cables (eg 2 float, 2 optical, 1 float and 1 optical, 1 float and 1 leak detect etc) but the problem persists. If I only plug one sensor of any type into the purple port and one sensor of any type in the green port, everything seems to work fine.

Any help in resolving this would be appreciated.

NB: The P4 arrived with firmware 7.07. After encountering the problem I updated it to 7.08 but the problem remains. I am also using Control Centre 1.1.0.0.


Thanks,
Stephen.

Stephen,

What are you actually trying to do with these 4 sensors? Let's start there.

My goal for the sensors and Switch Channels is as follows:

1- ATO (single sensor). Action: engage pump as required.

2- High water alert, in case the ATO or something else overfills the sump. Action: trigger alarm, disable ATO and send email alert.

3- High water alert in AWC container. Action: trigger alarm, disable skimmer and send email alert.

4- Leak detection. Action: trigger alarm, disable skimmer and send email alert.

Thanks, Stephen.

First connect two sensors to the first PL-LY splitter, then connect it to the Level 1/2 port on your P4. Once you do that, identify which sensor is Sensor1 and Sensor2 by going to the LEVEL settings page and looking at the Settings and states level-sensor at the bottom of the page. As you trigger each sensor, an (X) will appear and disappear in the State (direct) column.

With Sensor1 identified, select an unused control circuit and set it to AUTO TOP OFF. Make sure to select Sensor1 as the sensor being used for this function. Specify the max on-time for this function. This is a failsafe feature which will shut down the function and assigned outlet in case the sensor or socket does not react within the allowed max time.

For sensor 2, select an unused control circuit and set the operation mode to LEAKAGE DETECTION. Make sure to select Sensor2 as the sensor being used for this function.

Identify sensor 3 and 4 when they are connected to the second PL-LY on the Level 3/4 port. Sensor 3 and 4 should also be set to LEAKAGE DETECTION.

We have a video which shows you how to setup a 1-sensor ATO function here:

Thanks for your reply Vinny. I have however been through the GHL Youtube videos prior to starting this thread but it did not resolve the problem.

Following your advice:

"First connect two sensors to the first PL-LY splitter, then connect it to the Level 1/2 port on your P4. Once you do that, identify which sensor is Sensor1 and Sensor2 by going to the LEVEL settings page and looking at the Settings and states level-sensor at the bottom of the page. As you trigger each sensor, an (X) will appear and disappear in the State (direct) column"

- when I connect two float sensors to the purple port via the PL-LY, if EITHER OR BOTH sensors are in the 'down' position Sensor 1 displays "-".
- only if BOTH sensors are in the 'up' position sensor 1 displays "X".
- sensor 2 displays as "X" at all times regardless of which position the sensors are at.


I have attached four images showing the position of the float sensors and the 'Settings and states level-sensor' screen confirming this.

I get the same result using the other PL-LY and / or the optical sensors too.



Continuing on with your suggestion:

"With Sensor1 identified, select an unused control circuit and set it to AUTO TOP OFF. Make sure to select Sensor1 as the sensor being used for this function. Specify the max on-time for this function. This is a failsafe feature which will shut down the function and assigned outlet in case the sensor or socket does not react within the allowed max time. For sensor 2, select an unused control circuit and set the operation mode to LEAKAGE DETECTION. Make sure to select Sensor2 as the sensor being used for this function."

having set it up as per your instruction, the ATO function (linked to Switch circuit 1) activates when EITHER of the float switches is triggered.





Thanks again,
Stephen.

Vinny (or anyone else from GHL ) - do you have any idea why my Profilux 4 is not recognising and attributing the level sensors correctly?

Is it a firmware problem, or port problem, or cable manufacturing error?

What can I do to resolve the problem as I need to use the controller asap?

Tagging along here as I have the exact same issue.

Also to note I have tested this with Flow Sensors aswell, the P4 only see's 1 sensor when connect the Y-Cable.

Are you selecting the correct sensor number to assign to each Control Circuit?

Please post a screenshot of your LEVEL settings.

Hi

allow us a few days to have a deeper look into this.

Will come back to this topic ASAP.

Here it is with the Flow Sensors plugged directly to Port 1 & 3

Attachment 9749

Here it is with the Flow Sensors plugged into a Y Cable on Port 3[Green]

Attachment 9750

Here it is with the Flow Sensors plugged into a Y Cable on Port 1[Purple]

Attachment 9751

I also have the same results as the OP with the float switches.

Thanks for posting about you having the same problem JunkieHobbo. Hopefully we can get this sorted out soon!


Vinny / Matthias - attached are three images of my Level Settings, as requested. They are:

- 2 float sensors, triggered, connected directly to Purple and Green Ports (both sensors are recognised by the P4 correctly)

- the same 2 float sensors connected via PL-LY splitter to Purple Port (only 1 sensor being recognised, as sensor 1)

- the same 2 float sensors connected via PL-LY splitter to Gren Port (only 1 sensor being recognised, as sensor 3)


As previously mentioned, I get the same error no matter whether I use float sensors, optical sensors or the leak detect module.

Hi Vinny / Matthias. Have you been able to replicate the problem we are experiencing with the P4 level sensors? Do you have any idea how soon it can be fixed?


Thanks very much.

Was about to ask the same thing, You beat me to it!

Hello Stephen,

could you please tell me the version of gcc and the firmware you use on profilux 4.

As per my original post Marc, the P4 arrived with firmware version 7.07 and I encountered the problem with the level sensors with this version. I then updated to 7.08 but the problem still occurs.

I am using GCC 1.1.0.0.

Stephen.

We've tested hardware and software without any problems. The users are in 2nd-level-support.

For the benefit of anyone else following this thread (or reading it in the future), GHL think the problem may be their PL-LY splitter cables so they are sending replacement cables by snail mail.

I will update here when the replacement cables eventually arrive to let others know if this fixes the problem.

The replacement PL-LY cables have arrived and plugging them in immediately resolved the problem.

Thanks very much for organising the replacements Vinny.

Glad to hear things are back to normal. :)
