LO.L Removing a Module
The Axion is a complex
piece
of
equipment
and some
under-
sta:nding of its internal layout
is necessary
before
removing a rnodu-
le.
An input module has wiring
to the
master
section and backplates
and the stargtound wire. Every
8
modules
thete is a
power
".tpply
*iring. A11 of these wires
must be rcmoved before withdrawing
a
module from the console. Each
module has computer
grade
connec-
tors for ease of the disconnecl
Turn off the
power
supply.
Remove the
upper
sfrip which covers
the
module
and
the
plexiglass.
Remove the two module retaining
scl€ws.
It is often easier to also
remove the modules
positioned left and right of
the
module rmder
test.
It is now
possible
to carefully lift
the module
until
the module
*idng
can
be
unplugged. Now
temove all flat cables from the bot-
tom of the module PCB. At
this
point
extendet
cables
(if
ordercd)
can be connected.
The master sections can be rernoved
ftom
the ftame
in the sarne
way.
Because of the many flat cables
on the bottom
of the master sec-
tion, it is wise to temove all
retaining screws
from all mastet sec-
tions, and remove the blankmodule
on
the left/nght side of the
master section. This willallow
all the mastermodules
to be mo-
ved slightly without
unplugging
all the flat
cables. A
qualified
ser-
vice technician will be able to
service the
modules in this way.
