CYLINDER HEAD TEMPERATURE (Continued)
The CHT for all six cylinders are displayed on the LEAN page. The
cylinder with the hottest CHT is indicated by a cyan bar graph. The
CHT for cylinder number three has been demonstrated to be the
most critical, and operation with CHT 3 inoperative is not allowed.
The LEAN page will show a red X over any cylinder that has a
probe or wiring failure.
A thermocouple is installed in each cylinder head to provide the
signal to the GEA-71 that is processed and shown as cylinder head
temperature on the EIS.
EXHAUST GAS TEMPERATURE
Exhaust gas temperature is displayed by the EGT horizontal
indicator on the EIS. The indicator range is from 1100°F to 1500°F
with graduations every 50°F. The white pointer indicates relative
exhaust gas temperature with the number of the hottest cylinder
displayed inside the pointer. If a cylinder EGT probe or wiring failure
occurs for the hottest EGT, the next hottest EGT will be displayed.
The exhaust gas temperature for all six cylinders is shown on the
LEAN page. The hottest cylinder is indicated by the cyan bar graph.
The EGT for a particular cylinder may be shown by using the CYL
SLCT
softkey to select the desired cylinder. Automatic indication of
the hottest cylinder will resume a short time after the CYL SLCT is
last selected. The LEAN page will show a red X over a cylinder that
has a probe or wiring
iaiiure.
A thermocouple in the exhaust pipe of each cylinder measures
exhaust gas temperature and provides a voltage to the GEA-71 that
is processed and shown as exhaust gas temperature on the EIS.
