Heart Interface HF12-1200 - Operation; What to Expect

-Whq
using
6
volt
batteries
you
must
hook
up
pairs
in
series
ro
ger
l2
volts.
In
a series
configuration y9g
connec-t
the
p^ositive
post
of oni
banery
to
rhe
neg[tive
post
of the
orher.
Twelve
volts
will
be
available
from
the remaining
two
pbsts.
When
using
1.2.
volt
batteries-yoo
hgo$
them
up in
parallel.
In
this
configuration
you
connect
all the
positive'
poststogether
and
all the negative posts
together.
You
inay
connecr
the Heart
to any
pair
of
positive
and negative
posts.
If more
than
one
pairof
6 volt batteriei
is
used you
must
connect
them in
a combination
of
series and
parallel.
When
batteries are
connected
in
series
the voltage
of
the
banery
bank
is
equal
to
the
sum
of the voltage of
each
battery. If
you
connect
two
6
volt
batteries
in
series you get
12
volts.
The
app-lour capacity,of
the
battery bank
is
equal
to
the
amp-hour
capaiity
o?
one of
the
batteries.Forexample,ifyou
connectapairof
6volt250amp-hourgolf
cart
baiteries in
series
you get
aLZvalt 250
amp-hour
battery
bank.
When batteries are
connected in
parallel
the voltage
of the
bartery
bank is
the same
as
that
of each
battery.
The-
amp-hour
capacity
is
equal
to the
sum
of the
amp-hour
capacity
of
each
battery.
Forexample,
if
you
connect two 105
amp-hour 12
volt
batteiies
in
paiatlel
you
get
a
L2
volt
210 amp-hour
battery
bank.
For
a
final
example, if
you
connectfour
6 volt 250
amp-hour
golf
cart
batteries
in
a series/
parallel
configuration
you
get
a
12
volt
500
amp-hour battery
bank.
Use at least
0
(l/.0)
gauge_copp€r
cable
fitted
with the proper
terminals
for
your
battery
interconnections.
Make
sure
that
all connections
are
clean-and
tight.
OPERATION
It
is recommended
that all loads
be
turned off
or disconnected
before
turning
on the
F"ry.
This is especially
important
for
any high powered
loads,
and is less
imporrant
f6r
small
loads.
To operate
simply
move
the
power
switch
to the on
position.
Both
LED indicator
lights
will flash
momenrarily.
The
low
battery LED
will
flash red
and
go
out
first.
The overload
LED
will
flash
green
anci
go
our
after
the
low
battery
LED. The
unit is
now running
and
ready
to supply
AC
power
to
your
loads.
WHAT
TO
EXpECT:
There
are
virtually no
limitations
to what
will
operate
on
your
Heart,
within
the rating
of the
unit. You may
operate
fluorescent
and incandeicent
lighls,
refrigerators
and freezers]
computers,
televisions,
etc-
The tist
is virtually
endless.
Flectrical
appliances
fall
into
2 broad
groups,
resistive
and inductive.
Resistive
loads
are
simple
ones in
which
the
electricity
createi
heat
and no morion.
Typical
resistive
loads
that
you
may
operate include
incandescent
lights
or
electric heaters.-It
is
easy
to
figure
what
resistive
loads
will
work
on rhe
Heart,
any
resistive
road
within
the rating
will
opirate
fine.
Inductive loads
are
generally
those in
which
the electricity goes
through
a
coil
of wire.
These
loads
usually
contain
motors,
such
as fans
and refrigeratoisl
or transfo-rmers,
which
are
found
in
most
electronics
such
as
TVs,
computers
and
huorescent
lights.
Inductive
loads
require
a
larger
amount
of
power
to
get
them
started than
to run
them,
soiretimes
up ro
6 times
