Sequencer
The Sequencer menu option provides this-then-that mixing with a
time delay. Two different sequences (S1 through S2) are available
to control 2 functions each (A and B), in 2 timing directions
(forward or reverse). Sequences appear throughout function
screens as assignable switches.
CAUTION: Always review the action of a sequence on the
Monitor screen BEFORE operating the model to ensure
controls act as desired. Failure to do so could cause a crash,
resulting in property damage and or injury.
You can program multiple functions to sequentially activate in
response to an assigned switch. For example, an assigned Gear
switch can open gear doors, lower the gear, then close the doors.
In reverse, gear doors open, the gear retracts and the gear doors
close.
You can assign each Sequencer function to a switch in most
Function screens such as Flight Mode, Dual Rate, Mixing, Throttle
Curve, Pitch Curve, etc.
You can assign several functions to a sequence to decrease
the number of controls you need to touch during complex flight
transitions—for example, applying your assigned dual rates and
exponential when the landing gear deploys and the flight mode
changes.
If you select an S-Number-A sequence (e.g. S2A), the sequence
operates as a timed 5-position switch. An S-Number-B sequence
operates as a timed 3-position switch. The 5 positions correspond
to the sequencer values shown on the time delay graph in the
second Sequencer screen. In a function screen, highlight each
point (0–4) and select the switch position desired for a function to
be active.
When S1B (or another sequence-number-B) is selected as
a switch in a function, the sequence will operate as a timed
3-position switch. The 3 positions act as ‘kick points’ of the
movement at fixed percentages (equal thirds) of the sequencer
output. In a function screen, highlight each point (0–2) and select
the switch position desired for a function to be active.
Sequencer SetUp
1. In the first Sequencer screen, select 1 of the 2 available
sequences.
2. In the second Sequencer screen, assign a switch to the
sequence. We recommend using a 2-position switch.
Tip: If you need to use a 3-position switch, you must assign
one direction to two adjacent switch positions—e.g., 0 and 1.
Assign the opposite direction to the third switch position.
3. Assign the timing for the Forward and Reverse directions as
desired. There is no delay when you use the Nor option. You
may also select a delay time between 0 and 30 seconds.
4. Assign names for each sequencer function as desired.
5. Select either
Step (S) or Proportional (P) for the Sequencer
output.
Step: The sequence only changes at kick points. Otherwise,
there is a delay in the sequence until it reaches the next kick
point.
Proportional: The sequence movement is proportional be-
tween kick points. The sequence maintains rate and direction
until it reaches the next kick point.
6. Adjust the Sequencer motion percentages in the third screen.
For example, you may move points 1, 2 and 3 closer to the
beginning of the sequence so the motion occurs earlier. This
results in a delay between point 3 and point 4 at the end of the
sequence.
Testing the Sequence
The Sequencer function determines the response for channels
included in the sequence.
Refer to the Monitor screen to see how respective channels
interact in the Sequencer.
