and
approving
agency,
you
may
be
required
to
provide
addition
al
NA
V Source Select external
annunciators
near
the
HSI 1 COl. Spare relay
contacts
on
the
AK-950
connector
may
be used
for
this
purpose.
ADDITIONAL
RELA
Y~
The
AK-950
contains
24
relay pales. Some
installations
may
require
more
than
24
pales due
to
data lines, superflags, etc.
If
this
should
occur,
you
may
use one spare relay pole
to
switch
additional relays.
ln
cases
where
it
may
be
more
desirable
to
have ali
the
relay
switching
done
at a
remote
location,
(i.e.:
remote
mounted
equipment).
one relay pole on
the
AK-950
may
be used
for
switching
this
bank
of
relays. Please
note
that
the
maximum
relay
contact
rating
for
the
AK-950
is 2
amps
DC.
ROUTING
OF
GABLES
Care
must
be
taken
not
to
bundle
the
AK-950
logic and
low
level signal lines
with
any
high
energy
sources. Examples
of
these
sources
include
400
Hz AC,
Comm.
DME, HF and
transponder
transmitter
coax.
Always
use shielded
wire
when
shawn
on
the
installation
print.
Avoid
sharp
bends
in cabling
and
routing
near
aircraft
control
cables.
