Operating
principles
The
controller
displays
“
CAL”
when
it
is
powered
-
on
,
then
it
will
enter
auto
operating
status
after
5
seconds
.
If
the
input
current
meets
minimum
requirement
(
bigger
than
150
ｍ
A
),
the
controller
will
display
measured
grid
power
factor
COS
Φ.
In
full
automatic
setup
mode
,
the
controller
will
initiate
a
“
self
-
learning
process”
.
During
this
process
,
the
controller
will
compare
the
given
“
power
factor
value”
with
the
current
power
distribution
system
and
add
capacitors
automatically
to
improve
power
factor
.
In
the
meantime
,
the
controller
will
record
the
values
of
the
connected
capacitor
banks
and
use
the
smallest
capacitor
bank
as
the
reactive
adding
threshold
.
No
matter
in
automatic
or
manual
parameter
setup
mode
,
the
controller
will
compare
the
measured
inductive
reactive
power
demand
with
F
-
1
reactive
power
threshold
Qs
.
If
the
inductive
reactive
power
demand
is
larger
than
adding
threshold
,
the
lagging
indicator
will
start
flashing
.
After
delay
,
add
capacitors
level
by
level
until
the
grid
reactive
power
demand
is
lower
than
reactive
power
threshold
Qs
and
the
power
factor
is
not
bigger
than
target
power
factor;
when
the
power
factor
of
the
grid
exceeds
target
power
factor
,
the
leading
indicator
will
start
flashing
,
the
system
will
automatically
remove
capacitor
banks
in
operation
level
by
level
(
in
5
seconds
).

Manual
setup
mode
This

In
manual

mode
,
user
must
set

correctly
when
starting

machine
for
the

time
.
For
example
:
if

,
the
