1.1.1
Switching
sequence/
requirements
The
belt
feeder
has
the
following
conditions
and
requirements
with
respect
to
the
switching
sequence.
Drive
transportation
chain
including
oil
lubrication
The
belt
feeder
may
only
be
activated
in
automatic
mode
if
the
discharge
transport
(transportation
chain
including
drive)
is
functioning.
In
automatic
mode,
the
drive
of
the
transportation
chain:
may
only
start
turning
when
the
paddle
shaft
runs
for
at
least
5
seconds;
may
never
turn/
start
turning
if
the
paddle
shaft
is
not
running.
If
the
paddle
shafts
is
blocking,
the
discharge
transport
(transportation
chain
including
drive)
should
stop
immediately.

1.1.1 Requirements for the Switching Sequence of the Belt Feeder
Drive
transporta-on
chain
that
includes
oil
lubrica-on
You
can
only
start
the
belt
feeder
in
automa1c
mode
if
the
discharge
transport
(transporta1on
chain
that
includes
drive)
operates.
In
automa1c
mode,
the
drive
of
the
transporta1on
chain:
Can
only
start
to
turn
when
the
paddle
sha>
operates
for
a
minimum
of
5
seconds.
Cannot
turn
if
the
paddle
sha>
does
not
operate.
If
the
paddle
sha>
causes
a
blockage,
stop
the
discharge
transport
immediately.

The
drive
of
transportation
chain:
is
controlled
by
means
of
a
frequency
inverter;
is
executed
with
a
temperature
sensor
(PTC),
which
is
to
be
connected
to
the
frequency
converter.
if
the
PTC
is
measuring
a
too
high
value
at
the
drive
of
the
transportation
chain,
the
drive
must
be
stopped
immediately
by
the
frequency
inverter
–
based
on
an
error
message.
The
speed
of
the
frequency
controlled
transportation
chain
is
adjustable:
by
a
potentio
meter
connected
to
the
frequency
converter;
or
through
the
analog
output
of
a
PLC
control.
The
speed
of
the
transportation
chain
is
to
be
dsiplayed,
for
example
on
a
scale
of
0
to
100%.
If
the
drive
of
the
transportation
chain
is
turning,
both
oil
lubrication
devices
–
to
lubricate
the
chains
on
both
sides
of
the
transportation
chain
–
must
be
active.
Lubrication
can
be
done
in
pulse
mode.
See
section
Error! Reference source not found.
for
more
information
on
the
lubricator.

Drive
of
the
transporta1on
chain:
A
frequency
inverter
controls
it.
A
temperature
sensor
(PTC)
that
is
connected
to
the
frequency
converter
starts
it.
If
the
PTC
measures
a
value
at
the
drive
of
the
transporta1on
chain
that
is
too
high
and
shows
an
error
message,
use
the
frequency
inverter
to
stop
the
drive
inverter
immediately.
You
can
adjust
the
speed
of
the
frequency
controlled
transporta1on
chain
with:
A
poten-o
meter
connected
to
the
frequency
converter
The
analog
output
of
a
PLC
control.
For
example,
the
speed
of
the
transporta-on
chain
is
shown
on
a
scale
of
0
to
100%.
If
the
drive
of
the
transporta1on
chain
turns,
the
two
oil
lubrica1on
devices
must
be
in
opera-on.
They
lubricate
the
transporta1on
chains.
You
can
lubricate
in
pulse
mode.

Paddle
shaft
drive
including
standstill
monitoring
The
paddle
shaft
drive
is
executed
with
standstill
monitoring
by
a
proximity
switch
which
is
activated
each
revolution
of
the
paddle
shaft.
If
the
standstill
monitoring
proximity
switch
is
no
longer
being
operated:
both
drives
(transportation
chain
and
paddle
shaft)
should
be
deactivated;
an
error
message
with
visible
and
audible
alert
is
to
be
generated.

Paddle
shaJ
drive
with
stands-ll
monitoring
Each
paddle
shaJ
turn
starts
a
proximity
switch
with
stands-ll
monitoring
that
operates
the
paddle
shaJ
drive.
If
the
stands1ll
monitoring
proximity
switch
is
not
in
opera-on:
Stop
the
two
drives
of
the
transporta1on
chain
and
paddle
sha>.
You
will
hear
and
see
an
