1.3 Device description
ArrowWAN 2 is a compact radio module for
Maddalena MVM range water meters that
detects, transmits and remotely reads con-
sumption values and alarms using wireless
transmission technology.
ArrowWAN 2 uses the wM-Bus and LoRaWAN
protocols and is OMS and LoRa Alliance®
certied.
This guarantees a high level of interopera-
bility with various reading systems on the
market, including third-party systems.
The device manages several alarms (see
section "Radio module technical speci-
cations").
The factory set-up can, however, be modi-
ed through the NFC port and relevant app
installed on a device running the Android
operating system.
The main technical features of ArrowWAN 2
are:
– internal sensor that identies rotation of
the pointer on the meter using the princi-
ple of induction (immune to magnetic in-
terference), calculates the volume (in both
directions), manages alarms and stores
data in a non-volatile memory;
– wireless radio communication inter-
face:
-wM-Bus T1, C1 which enables remote
reading in Mobile Mode (walk-by);
-LoRaWAN, which enables remote read-
ing in Fixed Mode (AMR);
– lithium battery that guarantees power
for up to 15 years (depending on the set
conguration).

3 Use
The normal operating phase is remote
reading of meters through radio modules.
In AMR (xed) mode, each radio module
transmits the reading at a programmable
frequency. In mobile mode (Walk-By/Drive-
By), the radio module emits a data frame
with the measurements. To receive the ra-
dio module signal, hold a suitable receiver
near the meter. The xed (AMR) system
reads data automatically.
lWARNING!
Reading of data can be per-
formed using various software.
Please consult the metering op-
erator for more information on
the specic use of reading soft-
ware.

3.1 Synchronisation of
mechanical reading
The radio module stores the volume record-
ed via an inductive sensor. The module is
set-up in the factory with initial volume at
zero.
If the meter on which the radio module is
installed has a reading other than “zero”, it
may be appropriate to synchronise reading
of the mechanical meter and that of the
radio module using the programming kit.
Simply read the value in litres on the me-
ter and set the reading using the activation
software (refer to the “Activating the radio
module” paragraph).
3.2 Activating the radio module
The radio module is activated via the NFC
port located below the label next to the
module antenna, using the Android app
available on Google Play Store.
1
lWARNING!
It is necessary to use a smart-
phone with the Android operat-
ing system and the relevant app
provided by Maddalena S.p.A..
The app must be installed and set
correctly before proceeding with
the activation of ArrowWAN 2.

4 Maintenance
4.1 Battery
The radio module is tted with a lithium bat-
tery that cannot be recharged or replaced.
The typical lifespan of the battery is 15
years, calculated using factory set-up and
with the following operating conditions:
– between -10°C and +0°C for 10% of
lifespan
– between 0°C and +30°C for 80% of lifespan
– between +31 °C and +55 °C for 10% of
lifespan
lWARNING!
Humidity and intense heat may
damage the battery and reduce
its lifespan.
The radio module calculates the residual
lifespan of the battery on the basis of stored
parameters, such as estimated consump-
tion of the electronic board in stand-by
mode, transmitter consumption and num-
ber of transmissions performed.
Battery life depends on the data transmis-
sion frequency you choose to set.
4.2 Cleaning
No particular cleaning procedures are re-
quired. However, the installation area
should be kept clean and periodic checks
should be performed to ensure the required
environmental conditions are met.
dPROHIBITED
Use of abrasive products, petrol
or trichloroethylene is not per-
mitted.
4.3 Disposal
The device is made from various materials
such as metals, plastics, and electrical and
electronic components. It must be disposed
of in accordance with current local regula-
tions on industrial and special waste. It must
not be disposed of with household waste.
At the end of the product’s life, ensure safe
removal and responsible disposal of com-
ponents, including recycling of batteries, in
compliance with applicable environmental
laws in the country of installation.
