adding a level sensor

[reef]

I have currently 7 levels sensor, and want to add another as one of the sumps only has a low sensor level, not a high level water level sensor,

So initially this sump had one sensor i added another buy using a splitter cable.
It works for low level water, however i can't get the high water sensor to work as it does not show. what sensor number would this be? i assumed it would be 8 but when i activate sensor 8 it does not work.

Which model of PL do you have? Some models have level inputs that don't accept a splitter cable (Pl3 at second connector as example).

Proflilux 3EX


Oh, so it can only input 3 levels in total? seems strange,
So i have to add a exp module to add another level input.

Yes. The level port from the ex-addon has only one port and doesn´t support a splitter cable.

Yes. An EX-Box or, if a slot is available, the PLM-Level card

Most information shows it can support 4 levels

The PL3ex we talk about isn´t listet in that sheet.
The follower 3.1N eX has four level ports, that´s right, but the PL3ex has only three ones (I have a PL3 since 2010)
