operation is supplied through the 5-amp ENGINE INST circuit breaker
on Main Bus 1.
Serials 1582 and subsequent: Engine RPM is shown in the upper leftmost
corner of the MFD as both a simulated tachometer and as text.
The simulated tachometer receives a speed signal from a magnetic
pickup on the right hand magneto via the DAU and sweeps a scale
marked from 0 to 3000 RPM in 50 RPM increments.
Engine RPM is also continuously displayed in the engine data block
located in the lower right corner of the PFD.
In the event engine speed exceeds 2710 RPM for five seconds, the
MFD will display “Check RPM” in a red 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.
Exhaust Gas Temp / Cylinder Head Temp Gage/Bar Graphs
Serials 0002 through 1601, 1603 through 1643 and 1645 through
1662 without EMax Engine Monitoring: A 2¼” combination Exhaust
Gas Temperature (EGT) and Cylinder Head Temperature (CHT)
indicator is mounted in the right instrument panel. 28 VDC for
instrument operation is supplied through the 5-amp ENGINE INST
circuit breaker on Main Bus 1.
The EGT pointer sweeps a scale marked from 1250°F to 1650°F in
25°F increments. The EGT scale has no limit markings. The
electrically operated EGT indicator receives a temperature signal from
a thermocouple mounted in the exhaust stream of the #4 cylinder
exhaust pipe. The CHT pointer sweeps a scale marked from 200°F to
500°F. The electrically operated CHT indicator receives a temperature

signal from a temperature sensor mounted in the #6 cylinder head on
the left side of the engine.
Serials 1582 and subsequent: Exhaust Gas Temperature (EGT) and
Cylinder Head Temperature (CHT) readings are displayed on the MFD
as vertical bars that ascend and descend respective to increasing and
decreasing temperatures.
The EGT indicator receives a temperature signal via the DAU from a
sensor mounted in the exhaust stream of the #4 cylinder exhaust pipe.
The EGT bar and graph is marked from 1000°F to 1600°F in 100°F
increments. The EGT of the cylinder is displayed above the bar in text
and an up or down trend arrow appears below the temperature to
indicate whether EGT is rising or falling.
The CHT indicator receives a temperature signal via the DAU from a
sensor mounted in the #6 cylinder head. The CHT bar and graph is
marked from 100°F to 500°F in 100°F increments. The CHT of the
cylinder is displayed above the bar in text and an up or down trend
arrow appears below the temperature to indicate whether CHT is
rising or falling.
In the event CHT exceeds 420°F, the MFD will display “Check CHT” in
a yellow advisory box in the lower right corner of the MFD. In the event
CHT exceeds 460°F, the MFD will display “Check CHT” in a red
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.
Oil Temperature / Oil Pressure Gage(s)
Serials 1268 through 1581: A 2¼” combination Oil Temperature and
Oil Pressure indicator is mounted on the right instrument panel below
the EGT/CHT indicator. The instrument is internally lighted. 28 VDC
for instrument operation is supplied through the 5-amp ENGINE INST
circuit breaker on Main Bus 1.
The Oil Temperature pointer sweeps a scale marked from 50°F to
250°F in 25°F increments. The Oil Temperature indicator receives a
temperature signal from a temperature sending unit mounted at the
lower left side of the engine below the oil cooler.

Airplane Description SR20
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 1582 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
