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.
