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 M-
Bus (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 en-
closed 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 automati-
cally 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.
