ProfiLux 4 Programming Guide
EN 2017-02-06 62
Level sensors for the determination of the water level can be connected to the level
connections (mini DIN sockets: Level 1 & 2 purple, 3 & 4 green). Since these are double-
allocated sockets, you can connect two level sensors per socket using a splitter cable (Y-cable
PL-LY; not included).
Expansion cards can be used to increase the number of level inputs in ProfiLux 4 or Expansion
Box 2.
The numbering of the sensor inputs is continuous and begins with the sensors permanently
installed in the ProfiLux, followed by the sensor inputs of expansion cards (if available). The
fixed inputs of the first expansion box are then counted, then the sensor inputs of expansion
cards in the first Expansion box. The numbering of sensor inputs of further expansion boxes
is continued according to the same system.
Since the level control is a sensitive matter, various safety precautions have been taken. Our
sensors and the evaluation electronics are designed in such a way that a withdrawal of the
sensor plug or a cable break is interpreted as reaching the desired level and the
corresponding socket is switched off.
In addition to the more cost-effective mechanical float operated sensors, we also offer
optical or contact-less sensors (without mechanical parts). These cannot get stuck in a
position due to contamination. Furthermore, time limits are adjustable which limit the
switching duration of the sockets. Thereby, overflow due to a defect can be prevented in
most cases.
You can adjust the following level controls:

Diagnostic
After you have selected a level control, you can edit its settings.
After setting the level control (function), please assign the sockets
(hardware) to be switched by the level control, see also under System->
Socket outlet function.
Please note that you can assign any level sensor inputs to any control, this
