Please take note: This Quick Guide is not a replacement for the manual. It is only a brief overview of the functions of the alarm system. Detailed information about the alarm system can be found in the manual. The correspon- ding safety chapter of the manual is an integral component of this document.
Connection to Sensors in Potentially Explosive Areas In oil/petrol separator systems, only sensors that are approved for installation in potentially explosive areas can be connected. The safety class of the external equipment must correspond to the safety class prescribed for the entire system. Sensor Cable Sensor cables cannot be run in cable or conductor bundles together with other circuits.
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.

2 Installing the idOil-OIL oil sensor The sensor must be submerged at the desired installation depth when the liquid is at the separator’s standard liquid level (L). Notice manu- facturer´s instructions for oil separators. 1 Oil sensor idOil-OIL A Air B Oil C Water L Standard liquid level...
3 Installing the idOil-SLU sludge sensor The sensor must be submerged at the desired installation depth when the liquid is at the separator’s standard liquid level (L). Notice manu- facturer´s instructions for oil separators. 1 Sludge sensor idOil-SLU A Air B Oil C Water D Sludge...
