Error codes
An 'x' on error level 'b' and 'C' describes how often this error has
occurred. If a group error occurs more often than 9 times, a line '-'
is shown here.
EA10 General device error
EA11 Hardware error
EA12 Memory error/loss of data
EA20 Parameters outside the tolerance limit
EA21 Main battery low
EA22 Backup battery low
EA30 Tolerance error of another system device
EA31 Primary address conflict (address assigned twice)
EA38 Clock error
Eb1x Device error (hardware or memory)
Eb2x Battery too low or device outside tolerance
Eb3x Errors 1 and 2 occurred
Eb4x Communication to network interrupted
Eb5x Errors 1 and 4 occurred

Err1
Device is not supported
Err2
Device is not accepted
- Lists are full e.g. more than 500 metering devices
- External device supplying false data or error
Err3
Authorisation has failed.
- External device waiting for correct login and password.
Err4
Break in communication
- Connection interrupted before end of communication
Err5
Wrong configuration.
- Node still in idle mode
- Pulse adapter not parameterised
- External network nodes not in idle mode
Acknowledging errors
After errors have been noted, they can be deleted by acknowledging
the error messages. To do this, change to the display level "E" by
pressing the blue DISPLAY key repeatedly. When the DISPLAY key
is kept pressed for more than two seconds, all the errors on the "EA"
level are deleted. If the error state occurs again, the error code will
reappear on the display.

Installation instructions
Installation location
The network nodes WTT56.. have only been designed for applica-
tions inside buildings. The type plate is on the inside of the device
cover.
Measures to avoid problems
Install the network node in a frost-free environment and not close to
high-voltage cables or electrical systems or on metallic or conduc-
tive surfaces (read section 6.4 Brief installation instructions in the
system manual AMR before commissioning).
Silicone must not be used as an adhesive for gluing the WTT56.. in
place. If silicone is used as an adhesive for tiles etc., you must wait
for at least 24 hours after the use of the silicone before the WTT56..
may be installed.
Mechanical attachment WTT56..
The WTT56.. must be fixed to the wall using two screws. For this
purpose, two holes with a diameter of 6 mm must be drilled 184 mm
apart. Screws and dowels are included in the scope of supply.
Commissioning WTT56..
Start of service life calculation with a new battery:
After the network node has been fixed in place, the battery plug con-
nector is inserted into the plug connector provided (1). The network
node display reads
DISPLAY button once in order to start the service life calculation for
the new main battery.
Caution: It is possible to disconnect the main battery from the net-
work node during operation and then to insert the connector again.
In this case, do not confirm by pressing the DISPLAY key – this
would result in the wrong remaining capacity display.
Changing the battery: When a flat main battery is replaced,
the old battery is removed first and then the new one is inserted.
The operator then has to press the blue DISPLAY button once in
order to start the service life calculation for the new main battery.
The backup battery must not be disconnected at this point
since this would result in a loss of data.
Depassivation: When the main battery is stored for longer periods,
particularly at storage temperatures higher than 30 °C, passiva-
tion of the battery can occur. It is then no longer able to supply the
network node with sufficient energy. If the network node detects a
passivated battery, it automatically starts a depassivation cycle. This
is visualised by a flashing LED on the front. This process can take
several minutes. The network node then starts up in idle mode. If
the battery is cooled very heavily, this behaviour can also occur later
with other modes (e.g. installation mode).
