Parallel
operation (master-slave control)
*Two
or
more
units
of
the
same
machine
can be
hooked
up
in
parallel
to
give
an
increase
in output
current.
The
total
output
current
will
be
the
sum
of
the output
currents
of
the
individual
machines.
* In
parallel
operation,
one
machine
wi11 act
as
the masster
and
all others
wi
11
act
as
slaves.
The
output
voltages
and
output
currents
are
all
set
from the master machine.
*When
hooking the machines
up
in
parallei,
be
sure that all
the
power
ON/
OFF
switches
are
OFF.
HOOK-UP
PROCEDURE;
DTurn
the
power
switches
of
the master
unit

on
the back
panel)
on
all
the
slave
units
from
"MASTRE"
to
"SLAVE".
3)
Hook
up
the
parallel
operation-use
terminals
(IN/OUT,
located
on the
rear
panel)
of
the master
and
slave(s)
as
shown
in
Figure
5.
4)
For
connecting the output
terminals
of
each
of
the machines
to
the
load,
use
all
cords
of
the
same
length.
5)
For
(
+
)
and (-)
grounding
to
the
GND
terminal,
hook
up
the master
and
slave
machines via the
terminals
on
the
panels.
Figure
7
shows
the output connection
scheme
for (-) grounding.
6)
Set
the
voltage
and
current
knobs
of
all
the
slave
unit(s)
to
the
maximum
setting.
7)
Turn
the
power
switches
of
the master
unit
and
slave
unit(s)
all
to "ON".
Control
the
output
voltage
and
current
as
desired
via
the
voltage
and
current
knobs
on
the master
unit.
*When
the output
goes
to 0
amperes
in
the
parallel
operation
mode,
output
voltage
can no
longer
be
control led
by
the master machine.
Be
sure
to
keep
a
current flowing that
is
several
% of
the
rated current.
