Let’s
say
you
are
night
launching
and
wanted
to
activate
a
secondary
collection
of
lights
or
LED’s
once
the
rocket
is
in
flight.
You
can
wire
up
external
LED’s
or
lights
to
the
Aux
Terminals
of
the
RRC3
for
launch
activated
event.
This
example
illustrates
a
continuously
activated
set
of
LED’s.

The
Aux
Output
can
ignite
an
upper
stage
sustainer
or
air
‐
started
motors
using
simple
timed
operation
after
the
Launch
Event
trigger.
Keep
in
mind
the
Launch
Event
triggers
occurs
when
the
rocket
altitude
is
above
the
Arming
Altitude.
Calculate
a
Timer
Interval
by
adding
your
first
motor
anticipated
burn
time
plus
the
coast
time
you
desire
before
the
staging
or
airstart
event.
Timer
intervals
are
express
in
1/10th
second
values...
so
for
3
seconds,
use
a
value
of
30.

This
example
provides
the
same
timing
setup
from
the
previous
example,
but
adds
a
minimum
altitude
requirement
comparative
step
to
ensure
a
safe
minimum
altitude
has
been
reached
by
the
first
motor
burn
portion
of
the
flight.
The
comparator
is
checked
once,
and
if
the
minimum
altitude
has
not
been
reached,
then
no
Aux
Event
output
will
be
initiated.
For
this
example
we’ll
require
a
2000
ft.
AGL
minimum
altitude.
Remember
that
all
Comparator
Values
are
x100
,
so
for
a
2000
ft.
minimum
we’ll
use
a
value
of
20.
