Phase
The
selector
switch
permits
checking
to
see
if
all
Amptector
phase
inputs
are
operative
.
Since
all
feed
into
a
common
pick

and
timing
circuit
,
it
is
only
necessary
to
use
one
phase
to
check
out
all
the
solid
state
circuitry
functions
.
It
is
only
necessary
to
use
one
circuit
function
(
say
.
long

pick
-

)
to
verify
that
each
phase
(
A
.
B
and

)
performs
similarly
(
say
,
each
phase
trips
at
about
5
amps
