4.2.1. Installing the idOil-LIQ high liquid level sensor
The sensor is normally in air, and it issues an alarm when the sensing element is
submerged in liquid. The sensor is installed at a suitable height above the standard liquid
level (L) so that the overflow alarm is activated once the liquid level reaches the sensing
element.
Overflow is possible in the following cases, for example:
if the filter is dirty
if the automatic closure device is blocked
or if some other situation causes blockage in the discharge pipe

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.
