recommends Master Caution and Warning Lights be installed. Installation of Master Caution and Warning Lights is
covered in this manual.
Installing the MVP-50T may require an instrument (or two) to be moved to a new location. The MVP-50T replaces
eight or more primary instruments in the aircraft instrument panel, therefore moving an instrument to a new location
may not be an issue. If the installer is unwilling or unable to find a location for the MVP-50T, Do Not Install the
MVP-50T. The system may be returned for a refund (contact EI for more information).
2.5 Install the Temperature Probes:
Install only the Temperature Probes applicable for your configuration.
A. OIL Temperature Probe Installation:
The MVP system can interface with existing resistive or thermocouple type oil temperature probes or one
of EI’s Type-K sealed probes may be installed. See the EI pricelist for a list of available probes. Check
that the probe depth does not interfere with the inner workings of the engine.
B. OAT Probe Installation:
Mount the OAT Probe in an appropriate location on the aircraft, using the hardware supplied. The OAT
Probe is sensitive to air temperature changes. For this reason, do not mount the OAT probe in the path
of the cowl or engine exiting air (i.e., on the belly of the aircraft). Also, if the probe is mounted in the
cowling area, radiant heat may inuence the probe temperature. Other than these considerations, the OAT
Probe may be mounted in an air intake vent, on the side of the cowling or anywhere else on the aircraft.
C. Other Temperature Probe Installation:
Other temperature probes (Cabin Temp, Cowl Temp for re detection, etc.) may be installed using current
aircraft standards and practices (refer to AC 43.13). Make sure these probes do not interfere with the
operation of the engine or aircraft.
