appear
on
the
LED
display
(1

At
the
same
time,
the
stripping
blades
open
and
position
themselves
at
the
right
stripping
length
in
accor-
dance
with
the
step
selected
.
In
this
position,
it
is
possible
to
alter
the
values
stored
in
the
memory
by
means
of
the
LOAD
switch
(1
).
These
values
are
entered
into
the
memory
and
then
onto
the
LED
display
digitally
by
means
of
the
thumb
wheel
switches
(2)
.
In
order
for
the
values
not
to
be
lost
when
the
machine
is
switched
ott,
the
memory
is
connected
to
a
battery
which
automatically
re-
charges
during
operation
.
The
"brain
"
of
this
machine
is
an
EPROM
(7)
pro-
gram.
The
EPROM
retrieves
the
data
in
the
memory
(9)
and
then
controls
all
the
functions
of
the
stripping
action
according
to
the
stored
pro-
gram
.
The
opto-sensor
(4),
which
is
at
the
other
end
of
the
sensor
,
switches

a

selected.
So
that
no
undesired
values
can
be
stored
during
operation,
all
inputs
(2)
are
blocked
immediately
after
the
start
by
an
electronic
switch
(8).
Then
,
the
sensor
solenoid
is
switched
on
via
the
amplifier
(16)
.
The
cable
gripper
is
switched
on-
after
a
small
delay-
via
the
amplifier
(17).
The
EPROM
(7)
now
selects
the
correct
data
from
the
memory
and
sends
the
data
to
the
digital-
analog
converter
(11)
with
analog
data
memory
(12)
.
The
two
amplifiers
(13
and
14)
with
positioning
feedback
of
the
motors
for
the
length
and
the
diameter
guarantee
repeatability
and
correct
positioning
of
the
stripping
blades
.
The
limit
circuit
(18)
prevents
damage
to
the
mechanical
and
electrical
parts
from
entering
data
beyond
the
range
of
the
machine
.
After
the
cycle
has
been
completed
,
the
Start/Stop
switch
(5)
is
reset.
The
SCHLEUNIGER
207
is
now
ready
for
another
cycle
.

Maintenance
The
maintenance
required
for
the
machine
is
minimal
,
but
must
be
strictly
adhered
to
for
trouble-
free
operation
of
the
machine
.
This
is
a
require-
ment
for
the
validity
of
the
guarantee.
Mainte-
nance
needed
on
the
machine
will
mainly
depend
upon
the
material
being
stripped
and
on
the
amount
of
stripping
waste
being
generated.
