Electronics International MVP-50P - Manual (Page 66)

2. The “To” value in the “Display Operating Range” field must be set to the same value as the Red
Limit for the EGTs. Note: This is the same value found on the “Bar Graph Setup” screen “High EGT
Range” field.
If these conditions are NOT met, the EGT Max Limit Line will be shown in gray.
Bar Graph (CHT Max Limit Line, MVP-50P):
If the following conditions are met, a CHT Red Max Limit Line will be drawn:
1. The “Cylinder” field in the “EGT/CHT Bar Graph Limits and Color Setup” screen must be set to
“ALL” for the CHT function.
2. The “To” value in the “Display Operating Range” field must be set to the same value as the Red
Limit for the CHTs.
If these conditions are NOT met, the CHT Max Limit Line will be shown in gray.
Gear Position, Unsafe Indicator and Gear Warning:
The Gear Position and Unsafe Indicator shown on the MVP System Screen are intended as a backup to
the aircraft’s existing system. The Gear Warning operates off the Gear Position, Unsafe Indicator, Air-
speed and Manifold Pressure. The Gear Warning provides a valuable feature (voice warning) for elimi-
nating gear up landings.
Unsafe Indicator: Operates from an “unsafe signal” from the aircraft. Displays as either Red or off on the
MVP.
Landing Gear Position: There are three options for interfacing the EDC to the aircraft’s gear system.
Option 1: Connect the EDC to the aircraft’s Right, Left and Nose Gear green down lights. The state
of each gear will be displayed independently on the MVP. Select Gear Left, RT and Nose for the
probes in Configuration Screen #1. This configuration requires three EDC inputs.
Option 2: Connect the EDC to the aircraft’s Nose Gear green down light. The state of all three gears
will be displayed on the MVP based on the Nose Gear’s state. Select “Gear All” for the probe in
Configuration Screen #1. This configuration requires one EDC input.
Option 3: Use this option to display only the Left and Right Main Gears (no Nose Gear) from a single
input. Select “Gear Main” for the probe in Configuration Screen #1. This configuration requires one
EDC input.
Note: When setting colors, use Green for down and White for up. Red will cause an error.
Gear Up Warning: To provide a Gear Warning, the MVP must be monitoring Gear Position, Airspeed
and Manifold pressure. A voice warning is activated on the following logic:
(Any Gear is up -OR- the Unsafe Indicator is on) -AND- Airspeed is less than a set value -AND-
Manifold Pressure is less than a set value.
Note: See the “Aircraft Number, Gear Warning and TAS Setup” screen to set values.
