15 to 20 minutes after
shutdown.

_______, service the oil level to ________.
ADD; MAX HOT.
Both the sight glass and dipstick are to be used for checking oil level
False. The sight glass is not to be used for checking oil level; only the dipstick is to be used for correct indication of oil level in the tank.

The engine oil pressure indicator may display oil
pressures up to_____ with the engine shut down due to the
design of the oil pressure transmitter
4 psi
If the main oil filter becomes clogged, the engine seizes up.
False. a filter bypass valve allows unfiltered oil to continue to lubricate the engine.
Oil pressure and temperature are sensed by transducers
_______ of the main oil pump and the signal is sent to
the _______.
Downstream; EDM
The EDM passes the oil
pressure data to a _________
signal conditioning unit (SCU)
What does the SCU do?
illuminate the warning annunciators on the central warning system (CWS) panel related to oil pressure.
When will the SCU activate only the red OIL PX
- if oil pressure drops to 40 psi or below when above idle power
- oil pressure drops to 15 psi or below at idle power.
When will the SCU activate the amber OIL PX
- oil pressure is between 15 and 40 psi at idle power
2. oil pressure drops to between 40 and 90 psi, for 10 seconds, above idle power.
