Section 8. Engines & Fire Protection
8.4.12 Oil Temperature
Temperature indications from the engine oil sensor are displayed with a digital
readout and a moving tape on the engine synoptic page. The scale of the tape is -
50°C to 150°C. An adjacent tape displays oil temperature limits. The green band
extends from 20°C to 135°C. There are two amber bands, one from 20°C to -40°C
and the other from 135°C to 140°C. There are two red bands, one from -40°C and
below and another beginning at 140°C.
When oil temperature is in the normal (green band) range, the digital oil temperature
value and indicator tape are white. If the oil pressure is in the caution (amber band)
range (either high or low), the tape and digital value are amber.
The amber bands incorporate a time delay for transient conditions.
If the oil temperature enters the high caution range of 135°C-140°C or the low
caution range of less than 20°C, the digital value and tape turn amber and a L (R)
ENG OIL TEMP LOW or L (R) ENG OIL TEMP HIGH caution message appears
instantaneously.
If a high oil temperature remains in the caution range for more than 90 seconds, the
digital value and tape turn red and a L (R) OIL TEMP HIGH warning message
appears.
If the engine oil temperature enters the high warning range of 140°C or drops below
the low warning range of -40°C, the digital value and tape turn red and a L (R) ENG
OIL TEMP HIGH warning message appears instantaneously.
Should the engine oil temperature sensor fail, a L (R) OIL TEMP FAULT advisory
message appears and oil temperature indications for that engine will be unavailable
and a red X appears in place of the oil temperature tape.
