Wall mounting
Install wall bracket with the enclosed wall plugs and
screws as shown below on a flat wall surface. Slide
NDC over the wall bracket to the NDC clicks.
Dismounting of the NDC from the wall
bracket: Use screwdriver or similar
tool to push the upper strap
of the wall bracket backwards and
then pull the NDC downwards.
Dimensions (LxWxH):
127mm x 40,6mm x 42mm
Commissioning
The NDC module features a Plug & Play
commissioning mode. After connecting the NDC
coupler to a water meter, the NDC checks once each
day whether a water meter is connected to it. If a
meter is in place and it is not in SLEEP mode, the
NDC module detects the default settings of the meter.
The NDC module retrieves the meter data according
to the meter configuration and transmits this via
wireless M-Bus radio or LoRa radio.
Here, the transmission interval, transmission mode,
encryption of the telegrams and content of the
telegrams are based on the respective meter
configuration.
It is generally possible to perform the radio activation
of an NDC module via the optical interface. For this
purpose, the ZENNER infrared optohead IR Combihead
and the ZENNER configuration software licence MSS
Configurator (for Windows operating system) are
required. Alternatively, the NDC module can be
activated also by using the ZENNER DEvice Manager
Basic or by illuminating the optical interface (> 20 s).
If an NDC module has been activated, the red LED on
the front side flashes.
If necessary, the radio transmission of an NDC module
can be deactivated via the optical interface by means
of MSS software and infrared optohead IR Combihead
or by using the above mentioned app.
NDC wM-Bus IP68:
Immediately after activating the device, the NDC
wM-Bus transmits radio telegrams at an interval of
30 s over a duration of 1 hour in order to support
easier installation (test reception). The transmission
is then switched over according to the respective
meter configuration.
The red LED flashes at short intervals for a period of
one minute after activation.
NDC LoRa IP68:
Following successful activation, the NDC sends a join
request to the server and waits for the join accept.
If no connection is made then a further request is
sent every minute (to a max. of 5 requests).
The indicator light (red LED) indicates the status of
the connection process:
– rapid flashing: Still no reply received from the
server
– slow flashing: Successful connection
If a successful connection is not established then
the device will send a join request every day until a
successful connection is made (LED does not display
subsequent connection attempts).
Data logger
The NDC modules do not include a data logger.
Logger data is stored in the respective meter.
