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

206
are
shown
in
Figure
16
and
for
the

are
mounted
behind
the
nameplate
and
can
be
accessed
by
removing
the
four
screws
securing
the
nameplate
.
The
boards
are
mounted
horizontally
in

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

procedures
are
similar
for
all
relay
models
;
the
target
test
procedures
are
similar
for
all

Time
PERIODIC
CHECKS
and
ROUTINE
MAINTENANCE
Considering
the
vital
role
of
protective
relays
in
the
operation
of
a
power
system
,
it
is
important
that
a
periodic
test
program
be
followed
.
It
is
recognized
that
the
interval between
periodic
checks
will
vary
depending
upon
environment
,
type
of
relay
,
and the
users
'
experience
with
periodic
testing
.
Until
the
users
have
accumulated
enough
experience
to
select
the
test
interval best
suited
to
their
individual
requirements
,
it
is
suggested
that
the
points
listed under
Acceptance
Tests
be
checked
at
an
interval
of from
one
to
two
years
.
The
procedure
outlined
under
Acceptance
Tests
can
be followed
.
SERVICING
CAUTION
REMOVE
ALL
power
from
relay
before
removing
or
inserting
any
of
the
printed
-
circuit
boards
or
output
relays
.
Failure
to
observe
this caution
may
result
in
damage
to
and
/
or
misoperation
of
the
relay
.
There
are
two
basic
approaches
that
may
be
followed
in
servicing
the
SAM
relay
.
One
approach
is
field service
,
where
an
attempt
is
made
to
replace
defective
components
at
the
relay
location
.
Generally
,
this
will
take
the
most
time
and
require
the
highest degree
of
skill
ana
understanding
.
It
can
also be
expected
to
result
in
the
longest
system
-
outage
time
.
The
preferred approach
is
board
replacement
,
where
a
determination is made
as
to
which
printed
-
circuit board has
failed
and
that
board is
replaced
with
a
spare
board
.
The
system
can
quickly
returned
to
service
.
Considerable
time is saved and there is much less
pressure
to
make
a
decision
about
what
to
do
with the
defective
part
.
This
approach
typically
yields
the
shortest
down time
.
It
is recommended
that
a
complete
set
of
spare
printed
-
circuit
board
be
kept
at
the
main
maintenance
center
.
For
those who
wish
to
repair
at
the
component
level
,
drawings
are
available
from
the
factory
.
When
requesting drawings
,
the
following
information
must
be
supplied
to
the
factory
.
The
assembly
number
of
the
p
/
c
board
.
This is found
on
the

The
acceptance
tests
should
be
performed
after
a
printed
-
circuit
board
has
been
repaired
or
replaced
.
Whenever
the
nameplate
is
removed
from
the
relay
,
care
must
be
taken
when
replacing
it
so
that
it
does
not
interfere
with
the
mechanical
operation
of
any
switches
that
protrude
through
the
nameplate
.
RENEWAL
PARTS
It
is
recommended
that
sufficient
quantities
of
renewal
parts
be
carried
in
stock
to
enable
the
prompt
replacement
of
any
that
are
broken
or
damaged
.
When
ordering
renewal
parts
address
the
nearest
Sales
Office
of
the
General
Electric
Company
.
Specify
the
quantity
required
,
the
name
of
the
part
wanted
,
the
part
number
if
known
,
and
the
complete
model
number
of
the
relay
for
which
the
part
is
required
.
The
table
below
lists
the
part
numbers
for
the
most
common
replacement
parts
.
It
is
recommended
that
renewal
parts
only
be
obtained
from
the
General
Electric
Company
.
Should
a
printed
-
circuit
card
become
inoperative
,
it
is
recommended
that
the
card
be
replaced
with
a
spare

,
Q
5
and
Q
6
.
The
base
of
Q
5
is
referenced
to
13.2
VDC
by
Z
1
(
12
VDC
)
and
D
6
&
D
7
.
Current
limit
,
which
is
set
for
24
mA
,
is
provided
by
R
39
and
Q
7
.
When
the
voltage
drop
across
R
39
,
a
24.9
n
resistor
,
exceeds
0.6
VDC
,
Q
7
turns
on
and
takes
base
current
from
Q
5
.
This
action
turns
off
Q
5
,
thus
causing
the
output
to
collapse
.
Q
8
,
R
40
and
Z
2
provide
6
VDC
for
use
by
the
driver
circuits
.
Timing
The
timing
circuit
(
s
)
,
Input
1
and
/
or
Input
2
,
are
driven
by
an
oscillator
circuit
.
The
oscillator
circuit
,
which
consists
of
three
U
4
inverters
,
three
resistors
,
R
5
,
R
6
&
R
46
and
a
capacitor
,
C
8
,
is
tuned
to
2
kHz
.
The
oscillator
clocks
the
binary
counter
,
U
3
.
The
output
of
U
3
becomes
the
clock
signal
for
U
6
,
which
is
another
binary
counter
.
Through
different
segments
of
the
range
multiplier
switch
,
SW
3
,
the
output
of
U
3
as
well
as
the
output
of
U
6
become
the
clock
signal
for
BCD
counters
U
1
and
/
or
U
8
.
Setting
SW
3
to
the
extreme
left
position
,
the
0.01
setting
,
will
program
U
3
to
divide
by
20
and
its
output
is
connected
to
BCD
counters
U
1
and
or
U
8
.
With
SW
5
set
to
the
mid
position
,
the
0.1
setting
,
U
3
is
programmed
to
divide
by
200
and
its
output
is
likewise
connected
to
U
1
and
or
U
8
.
Placing
SW
3
to
the
extreme
right
position
,
the
1.0
setting
,
will
program
U
3
to
divide
by
200
and
this
output
clocks
U
6
,
which
is
programmed
to
divide
by
10
.
The
output
of
U
6
then
becomes
the
clock
signal
for
U
1
and
/
or
U
8
.
g
the
timing
switches
,
SW
1
&
SW
2
and
SW
4
&
SW
5
,
ON
,
to
the
UP
position
,
will
program
the
BCD
counters
to
the
desired
timing
interval
.
The
timing
interval
is
equal
to
the
sum
of
the
switches
in
the
UP
position
.
If
all
the
programming
switches
are
set
OFF
,
to
the
DOWN
position
,
the
circuitry
will
give
the
BCD
counters
a
default
setting
of
1
.
The
time
interval
,
due
to
the
default
setting
,
will
be
equal
to
the
setting
of
switch
SW
3
,
which
can
be
10
,
100
or
1000
msec
.
Settin
The
output
of
the
BCD
counters
,
U
1
and
or
U
8
,
goes
low
at
the
end
of
the
desired
timing
interval
.
The
transition
from
high
to
low
is
inverted
to
create
positive
edges
that
become
the
triggering
signals
for
flip
flop
U
10
.
The
BCD
counters
will
continue
to
count
at
the
maximum
possible
setting
of
256
counts
for
as
long
as
the
power
is
applied
to
the
circuit
.
However
,
the
flip
flop
,
U
10
,
will
change
state
on
the
first
positive
-
going
edge
and
ignore
all
subsequent
positive
edges
.
The
outputs
of
U
10
are
connected
to
pins
47
and
48
,
to
monostable
multivibrator
,
U
7
,
as
well
as
to
the
driver
circuit
(
s
)
of
the
output
relay
(
s
)
.
The
multivibrator
,
U
7
,
provides
output
pulses
of
approximately
20
msec
.
These
pulses
are
also
applied
to
the
driver
circuit
(
s
)
of
the
output
relay
(
s
)
.
Output
Each
driver
circuit
consists
of
non
-
inverting
buffers
,
resistors
,
diodes
and
a
transistor
.
Buffer
(
s
)
,
U
2
,
are
connected
to
the
12
VDC
supply
rail
and
provide
the
20
msec
,
pulse
signal
(
s
)
from
the
timing
circuit
(
s
)
to
the
driver
circuit
(
s
)
.
The
continuous
signals
from
the
timing
circuits
to
the
driver
circuit
(
s
)
are
provided
by
buffer
(
s
)
,
U
5
,
which
are
connected
to
the
6
VDC
supply
rail
.
Each
driver
circuit
can
be
driven
by
either
timing
circuit
.
Input
1
or
Input
2
,
but
not
both
.
The
selection
is
made
by
choosing
the
proper
resistor
combination
from
the
following
groups
,
R
19
thru
R
22
,
R

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
the
collector
of
the
drive
transistor
.
Wnen
active
,
the
transistor
,
which
acts
as
a
variable
-
series
resistor
to
the
relay
,
is
biased
in
the
linear
region
.
The
voltage
across
the
emitter
resistor
remains
constant
,
regardless
of
the
applied
battery
voltage
.
Since
the
voltage
across
the
resistor
is
constant
,
the
current
flowing
through
it
is
also
constant
.
Thus
the
collector
current
is
constant
,
regardless
of
the
battery
voltage
and
therefore
,
the
relay
is
controlled
by
the
current
and
not
the
voltage
applied
.
