Introduction:

 

The "Autosequencer" uses "real time programming" that will allow you to program your gear/door sequence in REAL TIME. What you see is what you’ll get. When setting up a gear/door sequence mode, you simply have to flip the transmitter retract switch, press and then release the remote timing button for both gear up and gear down. The Autosequencer does the rest for you automatically in REAL TIME. Once the timing sequence has been stored in memory, the unit will remember the timing forever or until you decide to change it. Timing delays of over 30 seconds are easily possible. The max delay for the unit is 61 seconds, but we just can't see anyone needing that much time.

 

 

Autosequencer Components:

Please take a few minutes to familiarize yourself with the general layout for the Autosequencer’s input and output ports as well as the external components for the unit. The photos below should help you to locate each component, it’s correct placement, orientation and use.

In addition to the unit. The system comes with all the components shown in the photo below:

The photo below shows all the unit's connections.

 

The unit is shown here with everything plugged into it.

From left to right, top to bottom. MCUPWR lead (signal lead-yellow, orange or white faces up and doesn't connect to either of the two power pins, the ground lead is on the bottom.)

RDYLIGHT: (green "system armed" light) plugs into the 2 pins directly below the MCUPWR pins. The green lead faces up.

NOTE* ALL servo/valve signal leads face the same direction as shown in the photo. Down away from the top of the label. Lead colors can be white, yellow or orange depending on the servo/valve manufacturer.

GEAR/DOOR1 ports: The next sets of pins are for the Gear Out (bottom set of pins) and the Door1 (main gear doors) top set of pins.

DOOR2/DOOR3 ports: the lowest sets of pins on the left side of the unit are for Door2 and Door3 outputs. Door2 is the bottom set of pins and Door3 is on top.

The right side of the unit houses the programming block port (SW4) and the remote timing switch (SW3). No polarity is necessary for these sets of pins.

 

The two push buttons SW1 and SW2 are clearly marked on the top of the unit with the programming dial centered between them. The blue ATV adjustment pot is to the left of  SW2.

The two LED lights visible thru the top of the box are RED (set point LED) and GREEN (programming set LED).

When using the programming dial, be sure the small arrow in the center of the dial is pointing directly at the function you are trying to use.

Assembly of the remote timing switch/ready light holder mount:

 

 

 

This photo shows the assembly of the remote timing switch/ready light holder. The ready light mount thru the small hole on the lower right and is held in place by a small drop of CA. The remote timing switch is shown mounted in the thumb tab using the small nut included with the switch. The remote timing switch then mounts in the crescent shaped notch in the mount. 2) 2-56X5/8" servo screws are provided to mount the holder in the airframe.

 

 

Glossary of terms:

MCU: Micro Controller Unit (the Autosequencer’s brain)

Remote timing switch: SW3 on the controller. Switch leads plug into the SW3 port pins on the controller. No polarity.

Programming Block: small black plastic shorting block used to "set" programming.

Ready light: 3mm green LED light. Plugs into port pins adjacent to the MCUPWR pins, green lead facing up. When "on", this light signals the system is ARMED.

 

Choosing the correct sequence mode:

 

To use the Autosequencer, you must determine the sequence mode for your aircraft. The list below describes all the gear/door sequence modes available on the Autosequencer unit.

 

MODE 1: While Gear is down, main and nose doors stay open. Gear switch up, main and nose doors stay open, once gear is up, doors close.

MODE 2: While Gear is down, mains doors are closed, nose door* stays open. Gear switch up, Mains doors open, nose door stays open, once gear is up, all doors close. Gear switch down, Main and nose doors open, gear comes down, after gear is down, main doors close, nose doors stay open.

*Note: MODE 3 has two uses. If you need MODE 2 to close the nose doors instead of keeping them open, use MODE 3, using the door 1 and door 2 ports. This will allow the nose door to close instead of remaining open.

MODE 3: While Gear is down, mains and nose doors are closed, aux doors (any extra set of doors) stay open. Gear switch up, mains and nose doors open, aux doors stay open, gear retracts, once gear is up, all doors close. Gear switch down, all doors open, gear comes down, main and nose doors close, aux doors stay open.

These four gear/door modes should enable you to program any gear/door sequence necessary. We can also make custom program changes if needed for any type gear/door sequence upon request.

 

 

(System Do’s and Don’ts)

Q and A’s

 

The Autosequencer is very smart, It will do exactly what it is told...The catch is that if it is told the wrong information, damage can occur to the aircraft or the unit. Here are a few Do’s and Don’ts for the system.

"DO" Please read the entire instruction set to become familiar with the Autosequencer’s program procedures before setting up your aircraft.

"DON’T" Charge the air system in the aircraft until told to do so. Airframe damage will occur if you fail to listen to this warning!

The Autosequencer uses two separate inputs for power. The receiver powers the servos or valves thru the gear input connection. The MCU has a separate set of power input pins. You may use a "Y" connector from the battery switch (before it is plugged into the receiver) or you mat use a separate 6v. battery and switch.

 DO NOT use a "Y" connector from the gear input lead and receiver. The Autosequencer must use a separate power source for both the servo/valves and the MCU. This is used to isolate the two systems.

If you plan to use a separate battery and switch, the following instructions apply. ALWAYS turn on the MCUPWR switch before turning on the receiver switch. Failure to do so can damage certain types of servos.

 

Helpful Hints/ Q and A’s.

Once the programming block (SW4) is in place, "NO" program changes can be made, unless it is first removed. Think of it as a low-tech lock for the system.

Once the GEARSW, GEARATV or DOORs are set, they don’t need to be changed if you have to modify the timing sequence programming (using P1, P2, P3 on the dial) unless you change out a valve, servo or the receiver. The settings are retained in the unit’s memory and are separate from the timing sequence memory.

If you change out the transmitter for the aircraft, you need to change the GearSW settings only. The remaining settings will be unchanged. Simply go to the GearSw setup and follow the instruction set.

When all else fails, set the dial to "0" and RESET the power to the unit. Press both SW1 and SW2 at the same time and release. Once the red light goes out. All system memory is erased and you can start over with fresh settings.

If for some reason you have to turn off the unit while in the middle of programming, you’ll notice the red system light will be "on" when you power up the unit next time. Simply press the remote switch (SW3). This releases the gear safety lock on the system. Once the light goes out, follow the programming for the sequence instructions you are using.

If when in programming modes P1, P2, P3 and you forget and have the gear switch in the down position before pressing SW2, you’ll notice the gear or doors will be acting weird. simply press the remote switch once and then follow the instructions for gear up first, instead of gear down first.

 

General setup for use:

 

Be sure all connectors are plugged in correctly according to the photos and diagrams above before beginning setup. Be sure you are using a "Y" from the battery switch to power the MCUPWR pins. The receiver will power the servo/valves thru the gear input lead

Initial Setup Procedure: Programming the unit for the first time.

Turn on system, select "0" on the programming dial, press both SW1 and SW2 simultaneously and release. Wait until the red light goes out and then turn the dial to GEARSW (landing gear switch). ***NOTE***( "0" is the "RESET ALL" dial setting for the unit. You can use this procedure any time you want to start over from scratch.)

1. The first operation is to sync the gear switch on your transmitter to the Autosequencer. Begin by moving the gear switch on the transmitter to the "gear up" position.

2. Turn on the transmitter and press SW2, if the green light comes on, proceed to step 3. If the red light is lit, reverse the landing gear channel on your transmitter. Once the channel has been reversed, the green light will then come on and you can proceed to step 3.

3. After the green light goes out, the red light will come on and blink slowly. With the gear switch in the "UP" position, press SW1 and release. The red light will go out and the green light will come on briefly. After the green light goes out, the red light will come on again, blinking a little faster. Move the gear switch lever to the "DOWN" position and press SW2. The red light will once again go out and the green light will come on again briefly. This completes the GEARSW setup.

Turn the dial to GEARATV (retract servo/valve endpoints) and press SW2. The red light will come on solid. Adjust the trim pot so that the servo or valve is in the "Gear Up" position and press SW1, the red light will go out and the green light will come on and go out. Once the red light in back on solid, adjust the trim pot to the servo/valve "Gear Down" position and press SW2. The red light will go out and the green light will come on again and go out.

This completes the GEARATV setup.

 

DOOR PORT ASSIGNMENTS:

Door 1: Main gear doors

Door 2: nose gear doors

Door 3: Aux doors

The following procedure applies to all the door ATV’s.

Be sure the servo/valves are plugged into the appropriate ports for the sequencing  Mode # you are using.

2. Select  either DOOR1, DOOR2 or DOOR3 on the programming dial and press SW2. The red light will come on solid. Adjust the trim pot to the "Door Open" position for the servo/valve  and press SW1. The red light will go out and the green light will come on briefly, then go out. The red light will come on again. Adjust the pot to the Door Closed" position and press SW2. The red light will go out and the green light will come on briefly and then go out.

This completes the door servo/valve ATV setup.

Repeat the above steps for all door ports being used.

 

 

Gear/Door Sequence Programming

***Note***: the remote timing switch (SW3) will be referred to as "switch" in all the following sequence modes. "Holding the switch" will refer to just having the switch in your hand, ready to press the button when told to do so in the instructions. "Press" the switch will mean to "press the button" on the switch. "Press and hold" will mean to push the button on the switch and hold it down. "Release" will mean to take your finger off of the button on the switch.

Charge only your retract’s air system now. If the gear and doors are on the same system, unplug ALL the door port leads on the Autosequencer. Open the gear doors. This will prevent damaging the doors when the gear retracts for the first time.

MODE 1: Be sure your transmitter is on and the gear switch is in the "UP" position. Select P1 on the programming dial and press SW2.

Once the gear retracts, charge the door’s air system or plug the door leads back into the Autosequencer unit if they are all on the same air system. All the doors will then close.

Once the doors are closed, while holding the switch, flip the gear switch lever to the "DOWN" position. The Doors will open, press and release the switch when you want the gear to come down. After the gear is down and locked, while still holding the switch, flip the gear switch lever to the "UP" position. The gear will retract. Press the switch when you want the doors to close.

This completes the timing sequence for P1 ("Yes, it really is just that simple!")

Proceed to "Program Set" instructions below.

MODE 2: Be sure your transmitter is on and the gear switch is in the "UP" position. Select P2 on the programming dial and press SW2.

Once the gear retracts, charge the door’s air system or plug the door leads back into the Autosequencer unit. All the doors will then close.

Once the doors are closed, while holding the switch, flip the gear switch lever to the "DOWN" position. The doors will open, press and hold the switch when you want the gear to come down. Release the switch when you want the doors to close again. Once the gear is down and locked, while holding the switch, flip the gear switch lever to the "UP" position. The doors will open, press and hold the switch when you want the gear to retract, release the switch when you want the doors to close.

This completes the timing sequence for P2.

Proceed to "Program Set" instructions below.

 

MODE 2"A" : Using MODE 3 when you want the nose doors to close instead of staying open with MODE 2.

If you want the same operation as MODE 2, but would like the nose doors close when the gear is down, select P3 on the programming dial instead of P2 and plug the servo/valves into the door1 and door2 ports, not using the door3 port. Follow the procedure for MODE 3.

 

MODE 3: Be sure your transmitter is on and the gear switch is in the "UP" position. Select P3 on the programming dial and press SW2.

Once the gear retracts, charge the door’s air system or plug the door leads back into the Autosequencer unit. All the doors will then close.

Once the doors are closed, while holding the switch, flip the gear switch lever to the "DOWN" position. The doors will open, press and hold the switch when you want the gear to come down. Release the switch when you want the doors to close again. Once the gear is down and locked, while holding the switch, flip the gear switch lever to the "UP" position. The doors will open, press and hold the switch when you want the gear to retract, release the switch when you want the doors to close.

This completes the timing sequence for P3.

Proceed to "Program Set" Instructions below.

 

Program Set: This will set the system sequence programming for use.

 

Insert the programming block onto SW4’s two pins. Turn the programming dial to the appropriate MODE# you are using on the dial. M1 for Mode1, M2 for Mode2, M3 for Mode3.

Cycle the system power off and then back on to save programming and "lock out" changes. Remember, as long as the programming block is in place, NO program changes can be made, even by accident. You must remove the programming block before attempting to change any of the unit’s settings.

You’ll notice when the power comes back on, the red system light is on and the "RDYLIGHT" is off. This is the gear switch safety lock feature for the system. The remote timing switch (SW3) MUST be pressed to "ARM" the sequencer system. The system remembers the "last state" of the system when switched "off". This prevents the gear from being retracted on the ground by mistake. It takes a deliberate act (pressing the remote switch/SW3) to release the system lock; giving the pilot a chance to first think, check and then change any incorrect gear switch setting on the transmitter before the landing gear system is made "active".

Once the remote switch is pressed, the system is ARMED and ready for use. The green RDYLIGHT will come on. The gear safety switch will engage each time the system is cycled off and on. We feel this system is best because it will get the pilot used to checking the switches on the transmitter before turning on the aircraft.

"GEAR SAFE" system: The Autosequencer has a very unique gear switch safety system built in. After programming has been completed, the "programming set block" is in place and the M1, M2 or M3 modes have been selected; the Autosequencer will enter into the "Gear Safe" mode each time the system power is cycled off and on. You will notice the "red" programming light will be lit and the "readylight" will be off. The transmitter gear switch MUST be in the gear down position before pressing the remote switch to arm the system. Also, each time the "Gear Safe" system is engaged when powering up, you'll notice ALL the gear doors will be open until the gear switch is moved to the "down" position and the remote switch is pressed. Once the system is armed, the Autosequencer will return to the programmed sequence mode, the doors will close (if they are supposed to be closed in the sequence) and the "readylight" will come on, signaling the system is armed and ready for use.

Bypassing the Gear Safe system: To bypass the Gear Safe system, press and hold the remote switch when powering on the system. The Autosequencer will go directly to the programmed sequence mode and hold what ever position the transmitter gear switch is set for.

This completes the instruction set for the Autosequencer unit. If you have any questions, please give us a call.
