4.2.2. Installing the idOil-OIL sensor
The sensor must be submerged at the desired installation depth when the liquid is at the
separator’s standard liquid level (L).
The exact installation depth depends on the following:
separator type
separator shape
volume and height of the separator’s oil compartment
The sensor must always be immersed in liquid. The alarm is activated when the lower
surface of the oil layer reaches the alarm switching point (S), i.e. when the sensor’s
measuring electrode is covered in oil.
The sensor activates the alarm when it is in contact with air. For this reason, the separator
must always be filled with water after draining.

4.2.3. Installing the idOil-SLU sludge sensor
The sensor issues an alarm on sludge, sand or other solids accumulated at the bottom of
the separator.
The sensor’s exact installation depth depends on the following:
separator type
separator shape
maximum allowed sludge layer thickness
