Installation
To
ensure
correct
operation
and
reliable
and
consistent
level
measurements,
install
the
EGK-LW20L00
sensor
in
front
of
the
target
whose
distance
need
to
be
measured.
Screws
are
provided.
Mounting
could
be
vertical
or
horizontal,
depending
on
the
application.
The
device
measures
the
distance
to
the
closest
target
on
its
field
of
view.
It
works
with
different
materials,
for
example
water
level
in
rivers
or
flooded
streets,
snow
height,
waste
or
grains
level
in
bins
or
silos.
The
measure
is
performed
periodically
according
to
parameter

Power
ON/OFF
The
sensor
is
shipped
completely
off
to
prevent
battery
consumption
during
storage.
It
is
therefore
necessary
to
carry
out
a
first
power-on
prior
to
commissioning.
To
power
on
the
sensor:
lay
the
magnet
at
the
bottom
of
the
provided
tool
into
the
area
shown
in
the
figure:
m2m Germany GmbH | Am Kappengraben 18-20 | 61273 Wehrheim | 06081 5873860
Successful
power
on
is
signaled
by
the
flashing
of
the
3
LEDs.
In
case
of
long
period
of
inactivity,
if
necessary,
is
possible
to
shut-off
again
the
sensor
to
prevent
battery
consumption,

Measures
On
each
reading
of
the
sensor
by
LoraTool,
the
measured
distance
is
shown
on
the
main
page:
m2m Germany GmbH | Am Kappengraben 18-20 | 61273 Wehrheim | 06081 5873860
Once
provisioned
on
a
LoRaWAN®
network,
the
device
sends
the
distance
&
timestamp
to
the
server
via
uplink.
3.1
Level
settings
Level
measurements
are
carried
out
according
to
few
parameter
settings.
A
target
over
the
defined
range
cannot
be
detected.
Read
and
write
of
parameters
can
be
done
using
LoRaTool
App.
They
have
a
default
value
and
can
be
modified
to
be
tailored
on
the
specific
use
case.
Meaning
of
parameters
is
related
to
following
diagram.
The

5
Passwords
The
device
can
be
protected
by
passwords,
to
avoid
unauthorized
persons
to
read
data
or
modify
parameters.
As
default
passwords
are
equal
to
0.
Allowed
values
range
from
0
to
999999999
(only
numbers).
To
change
the
passwords,
set
the
new
values
with
the
LoRa
Tool
App:
m2m Germany GmbH | Am Kappengraben 18-20 | 61273 Wehrheim | 06081 5873860
Once
the
passwords
are
setted,
to
gain
access
from
LoRa
Tool
to
the
sensor,
open
the
App:
and
set
the
right
values
before
reading
from
the
device:
To
bring
back
the
sensor
to
factory
default
and
reset
the
passwords,
a
reset
code
must
be
requested
to
enginko
(please
provide
the
DevEUI
of
the
sensor
when
you
ask
for
that
code).
6
Configuration
file
WIth
LoRa
Tool
App
is
possible
to
configure
the
device
using
an
XML
file,
instead
to
manually
adjust
the
parameters
(for
details
about
the
file
format
please
ask
to
enginko).
This
is
very
useful
especially
in
case
of
multiple
devices
configuration.
With
“Save”
button
an
XML
file
with
the
actual
configuration
of
the
sensor
will
be
generated.
This
is
useful
to
store
or
clone
the
configuration,
or
to
send
it
to
enginko's
support
if
needed.
6.1
Multi
devices
configuration
WIth
LoRa
Tool
App
is
possible
to
configure
many
devices
in
an
easy
way.
For
multi-configuration
is
needed
at
least
one
XML
file
with
the
parameters
to
set.
Settings
on
this
file
will
be
applied
to
all
the
sensors.
With
an
additional
XLS
file
is
possible
to
load
different
LoRa
configuration
parameters
(Activation
Type,
AppKey,
AppEUI,
NetKey,
DevAddress,
Band,
Private
option)
for
each
sensor,
based
on
DevEUI.
When
the
sensor
is
approached,
if
one
parameter
is
different
from
files,
the
APP
will
ask
you
if
you
want
to
overwrite.
XLS
is
prevailing
on
the
XML,
so
if
both
files
are
enabled,
if
the
DevEUI
of
the
device
matches
one
of
the
DevEUIs
in
the
XLS
file,
LoRa
parameters
will
be
setted
from
this
one.
m2m Germany GmbH | Am Kappengraben 18-20 | 61273 Wehrheim | 06081 5873860
These
configuration
can
be
done
in
the
in
the
Settings:
Enable
or
disable
the
use
of
the
general
configuration
by
file;
Enable
or
disable
the
use
of
the

Verify
the
passwords;
