The WT…16… network nodes are used to receive and handle the data transmitted by
consumption meters of the Q AMR system. They are equipped with a gateway that
can provide data of up to 2,000 meters for remote readout. WTX16.IP can be read via
Ethernet while WTX16.GSM and WTX16.MOD-1 contain a GSM modem. They are read
via the telephone network.
Use
The WT…16… network node is a component of the Q AMR system. It has been designed
for use in buildings to create a radio network for receiving and storing the data transmitted
by the consumption meters installed in the building. Communication between several network nodes is via radio also so that no wiring is required. All measured values acquired by
the consumption meters are continuously exchanged within the network, which means that
every network node stores the current consumption values, the values read out at the end of
the month, and the set day values of all metering devices on the network. Owing to this
operating principle, all network data can be read out at any of the nodes, or a QUNDIS gateway for remote data transmission can be used with any of the nodes.

The WT…16… consists of the following blocks:
The transmitter and the receiver are used to
collect data from the consumption meters and
to forward theses data to other nodes in the
network the data memory stores the consumption data. It is protected against temporary
mains power failures by the backup battery.
The network nodes WTX16.GSM and
WTX16.IP are equipped with a gateway to
store data of up to 2000 meters and to provide
a possibility for remote readout via GSM or
Ethernet. The gateway has an additional MBus master that can drive up to 5 additional
external M-Bus unit loads (e.g. up to 5 additional M-Bus meters). Usually, however, the
M-Bus master is used to connect nodes of
different networks to be able to read more
meters using only one gateway.
For extension of M-Bus, is it possible to connect a repeater to the gateway.
The gateway can be programmed using an

Connect the AC 230 V power supply line to the power pack of the WTX16… in the
following order: Remove the upper housing section of the WTX16… from the
base. For that purpose, remove the 2 cable connections (power supply (4) and MBus (6)) between gateway and base. Then, use a suitable tool (screwdriver or
similar) to slightly open one of the two lateral fixing levers so that upper housing
section and base can be separated. Then, the top section of the WT…16 is to be
fitted using 2 dowels and screws (spacing of dowels is 184 mm with the
WTX16...).
Connection of the AC 230 V power line to the power pack of the WTX16... is to be made as
follows:
A 2-core mains cable (L and N) has to be preinstalled at the mounting site already. The
power pack must be connected by qualified staff. The cores must be sheathed with the enclosed insulating sleeves to ensure compliance with safety class II. Then, the live (L) and
neutral (N) conductors must be connected to terminal “IN” of the power pack. Mains voltage
must be in the range from AC 100 to 240 V (50 / 60 Hz). There is no protective earth (PE)
connection. Then, cable strain relief must be provided by fitting cable ties.
Once the top section of the WTX16 is fitted, the housing with the electronics can be snapped
on. Then, the power supply connector can be plugged into the electronics section and the
WTT16 switched to installation mode by pressing the MODE button (red) for a few seconds.
Then, additional network nodes or consumption meters of the Q AMR system can automatically configure themselves to form a network.
The standard baud rate of M-Bus master is 2400 Bd. To include 300 Bd M-Bus search it is
possible to switch this feature by parameterization software ACT21.
For updating M-bus device directory, there is an automatic search run for new connected
devices every 28 days. Devices, disconnected from M-bus, will be automatically deleted
from directory after 7 days.
After complete installation of all meters and network nodes, the gateway has to do a search
run to find all devices of network(s).
The search run started by triggering a command at the connected PC or by remote using the
software ACS26.
