NOW AVAILABLE

• Standard Features:  The Autosequencer is packed with the latest, state of the art electronic programming features for effortless gear/door sequencing.

  • Separate power inputs: One input for the central processor and one for the servos.

   

• Program selection via a multi position rotary selector dial, 2 push buttons and a remote timing switch,  allow independent programming for each of the following features.

  • Servo/Valve ATV's for the gear, door1, door2, door3 via trim pot (not buttons), independent from transmitter ATVs.

    • Reset all: resets entire system memory

      • Independent program timing for gear and all 3 door channels.

        • Remote push button timing for gear and all three door channels. Programs system delays in "real" time. What you see, is what you get! Set it once and forget it...

          • 4 modes of operation covering all types of gear/door systems

            • System programming lights, help guide the user thru the entire process

              • "Gear Safe" programming for a damage free gear/door system

                • Wide input voltage range. Works with 2.4 systems down to a super low 2V.

             

• Specialized Programming Example:

  • The special function timing circuit and ease of use is what sets the "Autosequencer" apart from all other sequencer units. With up to 65 seconds of delay time available for all functions, the user will never run out of delay time. Control for the delay time happens during the "actual" mode setup sequence. For example: When using mode 2 (F-86 type gear setup), that is, the mains and nose doors are closed when the gear is down. When selecting "gear up", the Autosequencer cycles the doors open first and then waits for the user to press the "remote timing switch" to retract the gear. From the moment the doors were opening, the Autosequencer starts counting in fractions of a second until the "remote switch" is pressed. Once the remote switch has been pressed, the "Autosequencer" stores the exact time the switch was pressed and retracts the gear. The "remote switch" is then held down while the gear retracts. Once the gear has retracted completely, the "remote switch" is then released, closing the gear doors. The "Autosequencer" stores the gear and door timing sequences in memory automatically in real time as it happens. If the user makes a mistake, or doesn't like the settings, the procedure can be repeated as often as necessary until the user is satisfied with the settings. Nothing is held permanently until the "program set block" is in place, locking out any changes. Setting the "gear down" sequence is equally as simple!  Once the setup mode has been completed, simply turn the rotary dial to the appropriate "MODE #" setting, plug in the "programming set" block and  the "Autosequencer" will remember the sequence forever. As long as the "programming set" block is in place, the unit's program settings cannot be altered, even by accident. The unit simply will not accept any new programming with the "set" block in place.

• Unit's Safety Features:

  • The "Autosequencer" comes with two important safety features built into the unit.

    • First, the unit uses a separate power supply for both the "MCU" (the brains of the unit) and the servo/valve control. Occasionally, when valves or servos move to control the gear/door sequences, they can cause a power spike to the sequencer unit. If the unit uses only the receiver input power from the gear channel and a spike occurs, the voltage can dip below the MCU's low voltage threshold and cause a "brown out" reset. Most of the time, these spikes go un-noticed at the servo or valve (under normal use), simply because the receiver and the servos catch up very quickly. Usually, what is noticed is a momentary "glitch" or a mild jerking of the servos, which quickly stabilizes.  However, when the power dips on the "MCU", it doesn't recover so easily and a reset is inevitable. This can be annoying, because it can cause a unit to operate erratically or not at all. The user is then left to figure out what has happened and why, but since the spike can't be seen, it goes undetected. If this type of failure happens in the air, the unit can cause the gear/doors to malfunction resulting in damage to the aircraft if the gear or doors fail to operate normally. With the separate power supply to the MCU on the "Autosequencer" unit, there can be NO RESET due to a power spike to the unit. Thus, the unit will always do what it was designed to do, every time!

      • Second, the unit has a power on "Gear Safe" feature that will not allow the gear to be retracted until the sequencer sees that the gear switch is in the down position and the remote switch is then pressed, thus arming the system. The gear safety system is activated each time the power has been cycled to the "off" position and then "on" again. It is not possible to accidentally retract the gear on the ground when the receiver power is turned on. When the "Gear Safe" system is activated, the gear is held in the down position and all doors automatically open. Once the gear switch is in the "gear down" position and the remote switch is pressed, the Autosequencer returns to the programmed "gear down" mode and closes the doors (if they are supposed to be closed). There is also a bypass for the safety system if the the user wants, for example, to keep the gear "up" when the power is turned on; to bypass the safety system, one simply has to hold down the remote switch when turning on the power. The Autosequencer will then hold, or change to what ever the transmitter gear switch position is. The bypass can only be used after the unit has been programmed and the "programming set block" is in place.
