bright
the
failure
is
definitive.

DESCRIPTION
SYSTEM REACTION
SOLUTION
If the system detects dry running during more than
10
seconds,
it
will
stop
the
pumps
and
the
ART
will
be
activated.
If
there
is
installed
an
external
device
as
a
level
sensor
,
when
this
one
detects
lack
of
water
it
will
stop
inmediately
the
pumps.The
system
will
show
the
message
of
lack
of
water
.
The
system
pumps
are
protected
against
over
currents
by
mean
of
the
intensity
values
established
in
the
installation
menu.
These
over
currents
are
produced
generally
by
dysfunctions
in
the
pump
or
in
the
electric
supply
.
This
device
has
an
electronic
safety
system
against
short
circuits
for
the
pumps
as
well
as
a
20
A
fuse.
The
presure
transducer
damages
are
showed
in
the
LCD
screen.
The
system
has
a
cooling
device
to
keep
the
INVER
TER in optimum operating conditions.
If an
excessive
temperature
is
reached,
the
own
system
leaves
it
out
of
service
and
as
consequence
the
pumps.
The
system
has
an
electronic
system
for
protection
against
short
circuits
as
well
as
a
fuse
of
20
A.
The
system
has
an
electronic
safety
system
against
overvoltages.
This
device
has
an
electronic
safety
system
against
too
low
supply
voltages.
The temperature sensor is damaged, it can´t
measure the instantaneous temperature or the
measuring is wrong.
EEPROM memory damaged.
Blank screen.
After
5
minutes
ART
system
will
start
again
the
first
pump
during
30
seconds,
trying
to
restore
the
system.
In
case
of
persistent
dry
running,
it
will
try
it
again
every
30
minutes
for
24
hours.
If
after
all
these
cycles
,
the
system
still
detects
lack
of
water
,
pumps
will
remain
permanently
of
f
until
the
damage
will
be
repaired.
In
the
case
of
having
an
external
level
sensor
,
if
this
device
detects
enough
level
of
water
again,
it
will
start
up
the
system
automatically
.
When
detecting
the
thermal
failure,
the
af
fected
pump
will
be
automatically
excluded.
The
operating
mode
EW
(Emergency
W
orking)
is
activated
and
the
other
pump
will
continue
operating
until
the
system
will
be
pressurized.
With
a
new
operating
cycle
(
pump
stopped
and
new
demand
of
water)
the
system
will
try
again
to
restart
the
excluded
pump.
The
control
system
will
carry
out
4
attempts
in
this
circumstances.
If
the
system
remain
locked
after
the
4th
attempt,
the
damaged
pump
will
remain
definitively
out
of
order
and
system
will
continue
operating
provisionally
in
EW
mode
until
the
damage
could
be
repaired.
The
operating
mode
EW
(Emergency
W
orking)
is
activated
allowing
the
system
to
continue
running.
The
device
operation
is
interrupted.
The
device
operation
is
stopped.
The pump remains stopped for 10".
Then it starts again - 4 attempts. If the problem is not
solved, the pump will remain definitively out of order
.
In
case
of
overvoltage
the
system
remains
stopped
during
some
seconds.
Then
the
operation
is
restored.
In
case
of
undervoltage
the
system
remains
stopped
until
an
adequate
value
of
voltage
is
reached.
In
this
case
the
system
is
automatically
restored.
The
device
operation
is
stopped.
The
device
operation
is
stopped.
There
is
a
lack
of
water
in
the
inlet,
it
has
been
activated
the
safety
system:
you
should
verify
the
feeding
of
the
hydraulic
network.
The
pumps
can
be

it).
V
erify
the
state
of
the

intensity).
V
erify
if
there
is
any

the
operation
will
be
restored
going
to
the

ALLA
TION
menu
(see
the
chapter
configuration)
and
insert
suitable
intensity
values.
V
erify
the
wound

the
pump
consumption
should
be
checked.
