Airplane Description SR22
The Oil Pressure pointer sweeps a scale marked from 0 psi to 100 psi.
The Oil Pressure indicator receives a pressure signal from an oil
pressure sensor mounted at the aft end of the engine below the oil
cooler. Normally, oil pressure may drop to 10 psi at idle but will be in
the 30 - 60 psi range at higher RPM.
Serials 1602, 1644, 1663 and subsequent: Oil temperature is shown in
the upper right corner of the MFD as both a simulated temperature
gage and as text. The simulated gage receives a temperature signal
from a sensor mounted below the oil cooler via the DAU and sweeps a
scale marked from 75°F to 250°F in 10°F increments.
In the event oil temperature reaches 235°F, the MFD will display
"Monitor Oil Temperature" in a red advisory box in the lower right
corner of the MFD.
In the event oil temperature exceeds 240°F, the MFD will display
"Check Oil Temp" in a red advisory box in the lower right corner of the
MFD.
Oil pressure is shown in the upper right-most corner of the MFD as
both a simulated pressure gage and as text. The simulated gage
receives a pressure signal from a sensor mounted below the oil cooler
via the DAU and sweeps a scale marked from 0 psi to 100 psi in 5 psi
increments.
Oil pressure is also continuously displayed in the engine data block
located in the lower right corner of the PFD.
In the event oil pressure falls below 10 psi or exceeds 99 psi, the MFD
will display "Check Oil Press" in a red advisory box in the lower right
corner of the MFD.
In the event oil pressure falls below 30 psi or exceeds 75 psi, the MFD
will display "Check Oil Press" in a yellow advisory box in the lower right
corner of the MFD.
28 VDC for the digital instrument operation is supplied through the 2-
amp ANNUN / ENGINE INST circuit breaker on the Essential Bus
Fuel Flow and/or Manifold Pressure Gage
Serials 0002 through 1601, 1603 through 1643 and 1645 through
1662: A 2¼" combination Fuel Flow and Manifold Pressure indicator is
mounted on the right instrument panel immediately below the
7-50 P/N 13772-001
