DESCRIPTION
The

as
explained
in

.
The

APPLICATION
The
SAM
200
relays
are
applied
wherever
accurate
and
repeatable
timing
functions
are
required
.
The
basic
timing
function
is
the
same
for
all
models
or
the
SAM
200
family
,
but
each
model
is
different
based
on
the
number
of
timing
functions
present
,
the
presence
or
absence
of
targets
,
and
the
contact
arrangement
.
This
differentiation
makes
certain
models
more
suited
for
specific
applications
.
Table
II
on
the
next
page
lists
the
models
and
their
recommended
applications
.

FUNCTIONAL
DESCRIPTION
The
SAM
relay
provides
the
following
basic
functions
:
regulation
,
timing
,
output
and
display
.
A
generic
block
diagram
for
the
SAM
relays
is
found
in
Figure
8
and the
internal
-
connection
diagrams
for
each
of
the models
can
be
found
in
Figures
9
thru
15
.
Regulation
The
input
power
is
regulated by
a
series
-
pass
Darlington
transistor
pair
that
provides
the
6
and
12
VDC
supplies
that
are
required
by
the
various circuits
on
the
timer
board
.
Timing
The
timing
circuits
are
driven
by
an
oscillator circuit
that
is tuned
to
2
kHz
.
The oscillator
circuit clocks
binary
counters
whose
outputs
become
the
clock
signals
for
BCD
counters
.
At
the
end
of
the
desired
timing
interval
,
the
BCD
counters
provide
the
input
signal
for
the
output
driver
circuits
through
the
JK
Flip
-
Flop
and
Multivibrator circuits
.
Output
Each
driver circuit is
capable
of
energizing
one
output
relay
.
The coil
of
the
output
relay
is
connected
in
series with
the
power
source
and
tne
collector
of
the
drive transistor
.
The
output
relay
contacts
consist
of
normally
open
(
NO
)
contacts
,
and
in
some
models
normally
closed
(
NC
)
contacts
.
These
contacts
will
change
state
when
the
output
relay
is
energized
.
The
operating
time
of
the
output
relay
,
which
must
be considered
when
selecting
the
desired
setting
of
the
SAM
relay
,
will
vary
depending
on
the
voltage
that
is
applied
to
the
relay
.
Figure
39
shows
typical
operating
time
of
tne
output
relay
with
respect
to
the
applied
voltage
.
Display
Some
of
the
SAM
models
provide
targets
that
are
connected
in
series
with
the
normally
open
contacts
of
the
output
relay
.
The
targets
will
be
energized
when
trip
current
flows
through
their coils
.

CONSTRUCTION
The
components
of
the
relay
are
mounted
on
a
cradle
assembly
that
can
easily
be
removed
from
the
relay
case
,
refer
to
Figures
32
thru
35
.
The
cradle
is
locked
in
the
case
by
latches
at
the
top
and
bottom
.
The
electrical
connections
between
the
case
blocks
and
the
cradle
blocks
are
completed
through
removable
connection
plug
(
s
)
,
as
shown
in
Figure
27
,
to
permit
testing
the
relay
in
its
case
.
The
cover
is
attached
to
the
front
of
the
case
and
includes
two
interlocking
arms
that
prevent
the
cover
from
being
replaced
until
the
connection
plug
(
s
)
has
been
inserted
.
The
case
is
suitable
for
semi
-
flush
mounting
on
panels
.
Hardware
is
available
for
all
panel
thicknesses
up
to
two
inches
.
A
panel
thickness
of
1
/
8
inch
will
be
assumed
unless
otherwise
specified
on
the
order
.
Outline
and
panel
drilling
dimensions
for
the
SAM
201
through
SAM
206
are
shown
in
Figure
16
and
for
the
SAM
207
they
are
shown
in
Figure
17
.
The
printed
-
circuit
board
(
s
)
are
mounted
behind
the
nameplate
and
can
be
accessed
by
removing
the
four
screws
securing
the
nameplate
.
The
boards
are
mounted
horizontally
in
guides
.
Each
board
is
labeled
to
correspond
to
a
given
location
.
Use
GE
part
number
0286
A
2847
rl
card
puller
or
other
suitable
means
to
remove
the
circuit
boards
.
If
you
do
not
have
a
card
puller
,
be
careful
not
to
damage
or
bend
any
components
when
removing
the
boards
.
A
card
puller
can
be
obtained
by
contacting
the
factory
.
The
output
relays
are
mounted
in
sockets
on
a
board
fixed
to
the
back
of
the
cradle
.
If
a
relay
requires
replacement
,
unclip
the
retaining
wire
and
pull
the
relay
out
of
the
socket
.
The
target
assembly
,
when
provided
,
is
mounted
on
the
bottom
plate
of
the
relay
cradle
.
RECEIVING
,
HANDLING
and
STORAGE
These
relays
,
when
not
included
as
part
of
a
control
panel
,
will
be
shipped
in
cartons
designed
to
protect
them
against
damage
.
Immediately
upon
receipt
of
a
relay
examine
it
for
any
damage
sustained
in
transit
.
If
damage
resulting
from
handling
is
evident
,
file
a
damage
claim
at
once
with
the
transportation
company
and
promptly
notify
the
nearest
General
Electric
Sales
Office
.
If
the
relays
are
not
to
be
installed
immediately
,
they
should
be
stored
in
their
original
cartons
in
a
place
that
is
free
from
moisture
,
dust
and
metallic
chips
.
ACCEPTANCE
TESTS
General
The
relay
should
be
examined
and

to
make
sure
that
no

has
been
sustained

that
the

functioning

CAUTION
Every
circuit
in
the
drawout
case
has
an
auxiliary
brush
.
It
is
especially
important
on
circuits
with
shorting
bars
that
the
auxiliary
brush
be
bent
high
enough
to
engage
the
connecting
plug
or
test
plug
before
the
main
brushes
do
.
This
will
prevent
the
secondary
circuits
from
being
open
-
circuited
during
insertion
of
the
connection
plug
.
A
drawout
case
relay
may
be
tested
without
removing
it
from
the
panel
,
by
using
a
12
XLA
13
A
test
plug
.
This
plug
makes
connection
to
the
relay
only
and
does
not
disturb
any
shorting
bars
in
the
case
.
The
12
XLA
12
A
test
plug
may
also
be
used
.
Although
this
plug
allows
greater
flexibility
,
it
requires
shorting
jumpers
since
connections
are
made
to
both
the
relay
and
the
external
circuits
.

General
Testing
Considerations
CAUTION
In
the
event
that
the
relay
is
tested
with
high
voltage
,
280
VDC
,
and
in
a
temperature
environment
of
greater
than
40
°
C
,
care
must
be
taken
so
that
the
relay
is
not
left
energized
for
a
period
exceeding
five
times
its
maximum
time
setting
.
Failure
to
observe
this
caution
will
damage
the
relay
.
The
relay
can
be
tested
by
using
one
or
two
simple
tests
.
These
tests
are
the
Timing
test
,
and
for
those
models
that
are
equipped
with
targets
,
the
Target
test
.
The
timing
test
procedures
are
similar
for
all
relay
models
;
the
target
test
procedures
are
similar
for
all
relay
models
that
include
targets
.
All
tests
should
be
made
with
the
relay
in
its
case
and
in
a
reasonably
level
position
.
Tests
For
the
following
tests
refer
to
Figures
18
thru
26
for
test
connections
,
and
to
Figure
29
,

and

of
several

models

INSTALLATION
PROCEDURE
The
relay
should be
installed
in
a
clean
,
dry
location
,
free from
dust and
excessive
vibration
.
It
should be mounted
on
a
vertical
surface
.
The outline
and
panel
-
drilling
dimensions
are
shown
in
Figures
16
and
17
.
Surge
ground
The
case
stud should be
permanently
connected
to
ground
by
a
conductor
not
less
than
AWG
No
.
12
copper
wire
or
equivalent
.
This connection
is
made
to
ground
the
relay
case
and
the
surge
suppression
networks
in
the
relay
.
The
surge
ground
lead should be
as
short
as
possible
,
preferably
10
inches
or
less
,
to
provide
maximum
protection
from
surges
.
