precautions.

The FPS-Plus-nt system is an automatic flap positioning system. It can be used in the manual positioning mode, or the automatic
mode. In the fully automatic mode, a "short touch" of the flap button, positions the flaps. A one second or more touch of the
flaps, commands the flaps to go to either the full up or full down position.
COMPATIBLE MOTOR ASSEMBLY TYPES for the FPS-Plus-nt
The FPS-Plus-nt system was designed to operate with flap motors that are "clutch driven". In other words, when these motors are
connected to the flap control surfaces, the motors cannot be over driven to damage the control surfaces or linkage components.
Most aircraft actuator motor assemblies have clutches or end stops built in them so that, . . for instance, when they reach the end
mechanical flap stop, the clutch slips so no damage is done to the flap or flap linkage.
NON-CLUTCH DRIVEN MOTOR ASSEMBLIES can be made to work.
If your flap motor assembly is not clutch driven, please refer to the alternate schematic published on our web for wiring.
ENCLOSURE INSTALLATION
The FPS-Plus-nt enclosure should be installed inside the cockpit area of the aircraft, away from excessive vibration and high
temperatures. The enclosure should be secured to a "metal panel" by the two holes provided on the bottom flanges of the
enclosure. The enclosure should then be electrically connected to the aircraft chassis common. In the case of a fiberglass aircraft,
you should run a separate wire to ground the chassis of the FPS-Plus-nt. The enclosure should be mounted so that the LED can be
seen for initial programming only. There is no need after that.
PROGRAMMING BUTTON INSTALLATION
It is not necessary to install the programming button on your instrument panel for the FPS-Plus-nt. It is not needed after initial
programming. Temporary connection is necessary for initial programming only.
WIRING
Review the wiring diagram included, along with the "Standard Aircraft Wiring Practices Guide". Wires depicted on the schematic
that have a larger thickness, (the motor current wiring to the power source) should be sized for the maximum amperage for that
motor circuit. An absolute maximum motor current of 10A is allowed for the FPS-Plus-nt. All other wires are low amperage
wires and can be #24AWG to #18AWG.
Avoid routing wiring for the FPS-Plus-nt, in the same vicinity of your radio transmitter antenna cabling or the
strobe light systems. This also includes devices such as the transponder or other types of RF transmitters, or
PRE-TESTING the FPS-Plus-nt AFTER INSTALLATION
PRE-TESTING the POSITION SENSOR DIRECTION
Whether your flap position sensor is separate or part of your motor assembly, you will have to ensure it is connected up properly.
Please pay particular attention to the direction of travel for the proper connections. When the position sensor (potentiometer) is
connected to the FPS-Plus-nt, it should be installed so that the "full up flap position" measures approximately 4.4Vdc to 4.95Vdc
into the FPS-Plus-nt system. The "full down flap position" should measure approximately 0.05V to 0.6Vdc. (measurements taken
from terminals 8 to 3) See the schematic diagrams for details. You can test these voltages when the potentiometers are connected
to the FPS-Plus-nt, and the unit is powered on. Using the FPS-Plus-nt in Mode 1, you can actuate the flaps and see this voltage
changing.
