Sequencer
TheSequencermenuoptionprovidesthis-then-thatmixingwitha
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
MonitorscreenBEFOREoperatingthemodeltoensure
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
responsetoanassignedswitch.Forexample,anassignedGear
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

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-positionswitch.The3positionsactas‘kickpoints’ofthe

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:Thesequenceonlychangesatkickpoints.Otherwise,

point.
Proportional: The sequence movement is proportional be-
tween kick points. The sequence maintains rate and direction
untilitreachesthenextkickpoint.
6. Adjust the Sequencer motion percentages in the third screen.
Forexample,youmaymovepoints1,2and3closertothe
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.
