2.15 Install the Resistive Fuel Level Module (RFLM-4-X):
The RFLM-4 is a Resistive Fuel Level Module that provides pull-up resistors for 4
resistive fuel level sensors. This module is required to interface an EDC Resistive
Fuel Level Input to a resistive fuel sensor. There are two RFLM-4 modules
available. The RFLM-4-12V operates on a 12-volt electrical system and the
RFLM-4-24V operates on a 24-volt electrical system. The appropriate model must
be used in your installation.
Mount the RFLM-4-X to the inside firewall or to an equipment bay under the
aircraft instrument panel. Use the holes in the bottom plate to mount the unit.
Only two mounting holes are required.
Note: Note: Note: Note: Note: For each Fuel Level Channel on the EDC you can use either the Resistive
Input or the Capacitive Input, but not both.
2.16 Install the Voice Alarm Control Panel (AV-17CP):
If the voice alarms provided by the MVP are to be used, the AV-17CP Control Panel will need to be installed in
the aircraft instrument panel.
A. A. A. A. A. Locate the Control Panel and Switch in the
AV-17CP packet. Find an appropriate
mounting location on the aircraft instrument
panel for the Control Panel and Switch. The
Switch will require a 3/4" clearance behind
the aircraft instrument panel.
B. B. B. B. B. Using the AV-17CP Control Panel as a template, mark the aircraft instrument panel and drill a 1/4"
hole for the AV-17CP Switch.
C. C. C. C. C. Mount the Switch from behind the aircraft instrument panel. Be careful not to damage the
silkscreening on the Control Panel. The Switch must be mounted with the white/orange wire up white/orange wire up white/orange wire up white/orange wire up white/orange wire up.....
The lock washer should be mounted on the Switch and behind the aircraft instrument panel.
2.17 Install the Intensity Control Pot (CP-1):
The display intensity of the MVP may be controlled
internally with an electric eye or externally with a
Intensity Control Pot (CP-1). The selection is pilot
programmable. If the intensity is to be controlled
externally, an CP-1 will need to be installed in the
aircraft instrument panel.
A. Locate the Intensity Control Pot in the CP-1
packet. Find an appropriate mounting location
on the aircraft instrument panel for the Control
Pot. The Pot will require a 2" clearance behind the aircraft instrument panel.
