Display
Explanation
Remote
access
C
During remote access the symbol ‚ ’ will be displayed.
Highspeed-
mode
for example
M
When all network nodes have switched on their receivers for
fast data exchange, this will be displayed as two dots in the
upper part of the LCD.
Bus-connection
(from version
2.2)
for example
If a connection to a bus is being built up, the number of
the bus and the primary address of this bus will be
briefly displayed .
In the example, network node 03 is connected to M-
BUS
IrDA-master
mode (from
version 2.2)
This mode is started by pressing the button MODE. (<
0,5 sec). It indicates readiness to connect additional
IrDA devices (in IrDA Slave mode). This mode stops
after 10 sec.
Add (from
version 2.2)
for example
If an unregistered IrDA-capable metering device (e.g.
WHE467) is connected in IrDA master mode, it can be
inserted into the network node by pressing the button DIS-
PLAY while ADD is displayed. The last 4 digits of device
number are indicated. (e.g. 20000123).
The registration of the device takes place and search mode
starts.
Delete (from
version 2.2)
for example
If an already registered IrDA-capable metering device is
connected in IrDA-master mode it can be removed from
the network node by pressing the button DISPLAY while
DEL is displayed. The last 4 digits of device number are
indicated (e.g. 20000123).
The removal of the device takes place and if necessary
search mode is stopped.
Copy (from
version 2.2)
for example
If a new network node (running in idle mode) is connected in
IrDA-master mode, it is possible to make a copy of all net-
work data into the new node by pressing the button
DISPLAY while COPY is displayed.
Copying lasts up to 20 minutes. At the end "StArt Prot" is
displayed on LCD of the new network node for 1 hour. After
mounting the new node the protected mode is also started
by pressing the DISPLAY button. By this procedure the new
network node is integrated in network and search mode is
started automatically.
Engineering notes
For detailed engineering instructions, refer to the Engineering Manual CE1J2870.
Commissioning the WTX..
For mains-powered WTX16.... network nodes, the mains connections are to be made first at
the selected mounting positions (typically on every second floor, mounting height
≥
2 m), if
required.
