 Oil system monitoring is performed by means of :
 - indications :
 oil quantity (quarts)
 oil temperature (degree celsius)
 oil pressure (PSI)
 oil filter clogging (OIL FILTER CLOG).

 These indications are displayed on the lower display unit of the ECAM system (main instrument panel) except the Master Chip Detector that gives a pop out information through its indicator in the fan compartment.

 OIL QUANTITY INDICATING SYSTEM - DESCRIPTION AND OPERATION

__________________________________________________________
 1. General
_______
 (Ref. Fig. 001, 002, 003, 004)

 A. Oil Quantity Transmitter
 - The oil quantity transmitter is located in the oil tank.

 - The system is power supplied with 28VDC from busbar 101PP (202PP), through circuit breaker 2EN1 (2EN2).

 - The oil quantity transmitter probe (tube portion) is a capacitor formed by two concentric tubes. The inner tube is shaped to achieve a linear output in a non-linear tank. The signal from this capacitor is rectified and goes to the electronics assembly on top of the transmitter.

 - Transmitter specification : Output voltage : 1VDC to 9VDC varying linearly with true oil quantity from 0 to 5.45 USgal (0 - 20.62 l) Charge impedance : 33 Kohms < charge impedance < 100 Kohms Accuracy : plus or minus 0.12 USgal (0.47 l)
