Description
General
The
Siemens
Series
81000
controller
is
an
integrated
system
of
contactors
and
components
arranged
for
convenient
access
within
a
common
enclosure
consisting
of
one
or
more
free
-
standing
structural
sections
.
Each
section
is
36
inches
wide
,
36
inches
deep
,
and
90
inches
high
(
100
inches
high
with
top
mounted
main
bus
)
.
Refer
to
Figure
1
.
The
medium
voltage
compartment
also
houses
the
current
transformers
and
the
contactor
.
In
order
to
open
the
medium
voltage
unit
door
,
the
contactor
must
be
de
-
energized
and
completely
racked
-
out
,
and
the
door
unlatched
.
Low
voltage
compartment
doors
may
be
opened
without
disconnecting
the
power
,
but
this
must
be
done
with
extreme
care
and
caution
.
The
Series
81000
controller
is
a
modular
design
which
can
be
arranged
to
meet
specific
customer
specifications
and
needs
.
Each
section
is
designed
to
accept
up
to
three
starters
with
one
low
voltage
control
panel
for
each
starter
.
The
unit
height
may
be
either
30
,
45
or
60
inches
.
The
electrical
power
is
distributed
through
the
optional
main
horizontal
bus
which
extends
the
entire
length
of
the
con
-
troller
.
The
bus
may
be
mounted
in
the
rear
of
the
upper
com
-
partment
or
inside
a
10
inch
high
top
hat
.
See
Figure

.
The
upper
units
of
1
-
high
and
2
-
high
controllers
may
contain
a
low
voltage
panel
or
space
for
future
starters
.
Each
vertical
section
containing

-
tors
is
fed
by
cables
or
a
vertical
bus
system
which
is
connect

bus
.
The
cables
or
vertical
bus
system
in
turn
supply
power
through
the
stab
assembly
mounted
on
the
cell
module
.
In
general
,
each
starter
unit
is
divided
into
medium
voltage
and
low
voltage
compartments
,
each
with
its
own
separate
door
and
interior
barriers

The

vacuum
contactors
are
suitable
for
application
without
protection
from
surges
related
to
switching
with
vacuum
,
except
for
jogging
or
inching
duty
with
small
(
under
100
HP
)
motors
.
For
such
applications
,
metal
-
oxide
surge
arrestors
or
surge
limiters should
be
specified
.
Regardless
of
the
switching
means
employed
,
if
the
insulation
integrity
of
the
motor
is
suspect
,
such
as
for
very
old
machines
,
it
may
be desirable
to
add
surge
protection
for
the
machine
,
or
to
consider
upgrading
the
machine
to
modern
insulation
standards
.
Isolation and
Automatic

Mechanisms
Non

finger
type
stab
assemblies
provide
the
means
for
manual isolation
of
the
power
circuit
,
in
accordance
with
NEMA
Standards
requirements
.
The
shutter
mechanism
operation
is
directly
controlled
by
the
position
of
the
racking
mechanism
,
and the movable insulated
shutter is linked
to
the
racking
cams
,
Figure

.
As
the handle
of
the
racking
mechanism is moved towards the
ON
position
,
the
insulated
shutter
uncovers
the line stab
assembly just
prior
to
engagement
of
the
contactor

and
load stab

,

In
the

,
when
the

Racking
Mechanism
and
Mechanical
Interlocks
Racking
of
drawout
contactors
is
accomplished
using
a
com
-
pound
four
-
bar mechanism
operated
by
an
external
,
enclosure
mounted
handle
.
The handle
can
be
locked
with
up
to
three
padlocks
in
the
OFF
position
.
Mechanical and electrical
interlocks
are
incorporated
in
the
racking
mechanism
to
perform
the
following
functions
.
Medium
Voltage
Compartment
Door Interlock
The
racking
handle is
interlocked
with
the door such that the
handle
cannot
be
moved
to
the
ON
position
while the
door
is
open
.
Refer
to
Figure
7
.
The
door
-
handle
interlock
(
item
2
in
Figure
7
)
prohibits
closing
or
opening
of
the
medium
voltage
compartment
door
except
when
the
handle is
in
the
OFF
position
.
The
flat
profile
on
the
end
of
the handle
shaft
will
not
allow
the door
-
handle interlock
to
pass
in
or
out
unless
the
handle
is
in
the
OFF
position
.

Door Interlock and Door
-
Handle Interlock
.
The door
-
handle interlock
should be
defeated
only
in
the
event
of
a
malfunction
in
the
racking
mecha
-
nism
.
The interlock
may
be
defeated
only by
authorized
and
qualified
personnel
.
Do
not
attempt
to
defeat
the interlock
unless all
incoming
power
is disconnected
,
grounded
,
and locked
-
out
.
Never
defeat
this
interlock
if
the
red
contactor
engagement
light
is
on
.
The
defeater
can
be reached
by removing
a
plastic
cap
from
the
lower
part
of
the handle
housing
,
then
by
removing
the
Allen
-
head
set
screw
.
The
racking
handle
must
be
rotated
approximately
23
degrees
from
the
fully
upward
(
ON
)
position
of
the
handle
in
order
to
align
the Allen
-
head
set
screw
with
the
access
opening
.
When
the Allen
-
head
set
screw
is
removed
,
the
handle
can
then
be
moved
to
the
OFF
position
allowing
the door
to
be
opened
.
Refer
to
Figure
8
.
After
the
malfunction
has
been
corrected
,
the controller should
be restored
to
normal
operation
by reversing
the
procedure
used
to
defeat
the interlock
.
Contactor
Interlock
To
prevent
accidental insertion
or
withdrawal
of
the
contactor
when
it
is
energized
,
an
interlock lever
moves
to
engage
notches
in
the
cam
when the
contactor
is closed
,
thus
pre
-
venting
motion
of
the
racking
mechanism
.
The interlock used
with
type
97
H
3
contactors
is
directly
actuated
,
and is illustrat
-
ed
in
Figures
11
and

contactors
employ
a

is
located
on
the

.
See

All
control
power
derived
from
the
secondary
of
the
control
power
transformer
is carried
from
the
contactor to
the
low
voltage
control
panel
through
a
set
of
contact
fingers
mounted
on
the
rear
of
the
contactor
.
Refer
to
Figure

.
Contactor
Engagement
Warning Light
A
red
warning
light
,
mounted above the handle
housing
is
energized
only
when the
contactor
is
fully
engaged
(
connected
to
the
line
and
load stabs
)
,
and
incoming
power
is
present
,
independent
of
the condition
(
open
or
closed
)
of
the
contactor
or
the door
.
When
the
handle is
moved
to
the
OFF
position
,
the red
warning
light
should
always
go
out
,
indicating
the
con
-
tactor
is
fully
disengaged
and isolated
from
the stab
assembly
.
Refer
to
Figure
10
These
contact
fingers
,
along
with
the
mating
contact
block
which is
stationary
-
mounted
on
the
guide
plate
,
make
up
the
Line
Switch
Interlock
(
LSI
)
.
The
function of
this interlock is
to
disconnect the load
from
the
CPT
secondary
prior
to
disengagement
of
the main
power
stabs
as
the
contactor
is racked
out
.
If
the
handle is moved
to
OFF
and
the red
light
stays
on
,
the
racking
mechanism is
not
operating
properly
and the
contactor
is
engaged
.
Do
not
attempt
to
open
the
high voltage
door
.
Disconnect and lockout
all
incoming
power
and
refer
to
the
"
Troubleshooting
"
section
.
Racking
Switch
Interlock
(
RSI
)
The
Racking
Switch
Interlock
(
RSI
)
is
a
microswitch
mounted
on
the
guide
plate
which
functions
to
prevent
operation
of
the
contactor
on
the
test
power
when
it
is
in
the
engaged
(
ON
)
position
.
As the
racking
handle
is
moved
from
OFF
to
ON
the
normally
closed
RSI
contact
opens
and
isolates the
test
source
from
the control circuit
