"MODE CHANGE" MODE

In this mode, you will not be able to move any control surfaces with the FPS-Plus-nt. The only thing you can do, is change

modes with the program push button. You are in this mode when the LED is blinking YELLOW.

(MODE OPERATION BEFORE PROGRAMMING)

NOTE: Before you program the FPS-Plus-nt, the normal operating modes (1 or 3) will function as follows:

Mode 1 - Full operation as described above

Mode 3 - Full operation as described above (except - the only positions that will be recognized, are flap full up, and full down)

MOTOR ZERO SPEED SENSING

If the FPS-Plus-nt commands a motor to move, and it senses that the motor is at or near zero speed, the FPS-Plus-nt will stop the

output command to move that particular motor within about 1 second. This is a built-in safety feature for your aircraft.

There is one mode that you must program, mode 5. In mode 5 you can program your flap positions or "flap stops". Reading

further will detail how this is accomplished.

CHANGING MODES

The first thing that you need to do, is learn how to change operating modes of the FPS-Plus-nt. This should be done only when

the aircraft is on the ground, and parked. A program push button (normally open switch) should be temporarily installed

between terminals 5 and 3. See the connection diagram. After the unit has been successfully programmed, this button should be

removed.

To change modes of operation, simply make sure there is no power to the FPS-Plus-nt unit. Depress the program button. Keep the

program button depressed, and then, turn on power to the FPS-Plus-nt. Keep the button pressed until the LED on the unit starts

blinking RED, rapidly. Now, release the button. Notice that the RED LED, will blink YELLOW, indicating that the FPS-Plus-nt

is in the "Mode Change" mode. The number of yellow blinks will indicate your present mode number. (For example, for mode 3,

the LED will blink 3 times then stop for a short time, . . then repeat that process)

release the program button once, to advance to the next mode. Notice that the number of LED blinks changes every time that you

press the program button. Do this until the LED counts, match the mode that you desire. After you have reached your desired

mode, turn the unit off. When you power back up, (without depressing the program button) you will be in the mode you just

selected. The unit will respond by blinking your mode number in RED, not YELLOW. Keep in mind, if the LED blinks

YELLOW, the only thing you can do is change modes. You have to power down, and then back up again to be in your desired

mode.

FLAP POSITION PROGRAMMING (Mode 5)

Programming of the flaps should be done only when the aircraft is on the ground, and parked. Temporarily install a

programming push button (normally open switch) between terminals 5 and 3.

In order to program the intermediate flap stops, you will need to put the unit in mode 5. Follow the previous instructions given in

"Changing Modes" to change to mode 5. Make sure the LED color is "RED", and blinking 5 times before proceeding.

Starting up in Mode 5

NOTE: This is the flap programming mode. Powering up the FPS-Plus-nt in mode 5, erases ALL previously programmed flap

stops. Another way to ensure that they were all erased, is to depress and hold the program button in for 5 seconds or more after

power up. The LED will turn GREEN temporarily, then blink RED very rapidly, letting you know that all previously programmed

flap stops have been erased. Now, release the program button. You may begin programming your flap stops.

Programming the flap stops

Just as a reminder;

1.) All intermediate flap stops have to be programmed. (It can be done in any order)

2.) DO NOT program the full up and full down flap stop positions! The FPS-Plus-nt will sense these automatically.

Using the flap up button, position the flap so it is in its "full up" position. Remove your hand from the flap button. Now, pressing

the flap down button, move the flap down to the first intermediate flap position you choose. Now, momentarily press the program

button (approx. 0.5 to 1 seconds). You will note that the LED will turn GREEN while the program button is depressed, indicating

that you have stored the first flap position. Press the "flap down" button again until you reach your next desired flap stop.

PROGRAMMING

Now, to change the mode, simply press and
