34.4.26.10 Exhaust Gas Temperature (EGT)
The EGT inputs on the GEA 24 and GSU 73 support configuration of Type K thermocouples.
If Lean Assist using EGT is desired, change the Lean Assist setting to "Enabled". (see
more information).
NOTE
The EGT 6/MISC PRESS input on the GSU 73 has multiple functions. If the GSU 73
EGT 6/MISC PRESS input has been configured for a sensor that is not an EGT
thermocouple, only four EGT thermocouples can be configured.
The GEA 24 can be configured to monitor exhaust gas temperature data from the
FADEC:
following FADEC interfaces:
• Rotax (912iS/915iS)
• Lycoming (iE2)
• ULPower
If two EIS LRUs are configured, up to 6 cylinders may be configured for a twin-engine application, or up
to 12 cylinders for a single engine. In a single-engine application, cylinders 1-6 are connected to EGT 1-6
on EIS LRU #1, and cylinders 7-12 are connected to EGT 1-6 on EIS LRU #2.
34.4.26.11 Fuel Pressure
The following sensors can be configured for the Fuel Pressure input on the GEA 24 or GSU 73:
• Kavlico P4055-15G (0-15 PSI, for most carbureted engines)
• Kavlico P4055-50G (0-50 PSI, for most fuel-injected engines)
• UMA N1EU07D (0-7 PSI differential, for some turbocharged carbureted engines such as the
Rotax 914)
• UMA N1EU35G (0-35 PSI, for most carbureted engines)
• UMA N1EU70G (0-70 PSI, for most fuel-injected engines)
• UMA N1EU70D (0-70 PSI differential, for some fuel-injected engines such as the Rotax 912iS/
915iS)
• UMA 1EM2K (0-2500 PSI, for certain turbine engines)
• Custom sensor
Custom: This option allows the installer to enter up to 8 points of voltage-to-pressure calibration. See pin
description in Section 25
