Siemeca™ AMR
Pulse Adapter AEW36.2
The AEW36.2 pulse adapter acquires and handles the pulses from 1 or 2 con-
sumption meters with pulse output and transmits the data to a Siemeca™ AMR
network. For setting the parameters, the pulse adapter is equipped with 2 inter-
faces, 1 wired interface and 1 optical interface.
Use
The pulse adapter is a component of the Siemeca™ AMR system.
It is for installations where consumption meters with pulse output are used the data of
which shall becollected by the Siemeca™ AMR system. Such devices can be meters
for hot water, cold water, gas, electricity, etc.
Functions
•Acquisition of the pulses delivered by the connected consumption meters
•Monitoring the connecting cable in the case of metering devices with NAMUR circuit
•Handling of pulses and storage of consumption data and set day values
•Wireless transmission of data 6 times a day to the WT..16.. network nodes of the
Siemeca™ AMR system

Ordering
When ordering, please give type reference: AEW36.2
Equipment combinations
When installing, the pulse adapter must be programmed with the data set delivered
with the parameter setting software for the respective meter. If meters not contained in
the meter data base shall be connected, a new data set must be requested from:

With the correct data set installed, the following types of meters can be connected:
−Water meters with pulse output
−Heat meters with pulse output
−Gas meters with pulse output
−Steam meters with pulse output
−Electricity meters with S0 interface (note: an additional WHZ.S0 converter is re-
quired, refer to Data Sheet CE1N2867)
Technical design
The pulse adapter handles pulses in accordance with the following specification:

The LCD of the pulse adapter has 4
display levels:
•Meter 1 („Zähler 1“)
•Meter 2(„Zähler 2“)
•Meter 1 statistics
•Meter 2 statistics
The display level currently used is
indicated by a little arrow (?) below
the name of the level.
A short press of the button produces a
switching action within the same dis-
play, a long press produces a change
from one display level to the next.
The first 2 display levels show current,
meter-related values. The other 2 dis-
play levels show 13 end-of-the-month
values of the relevant meter.
Display levels 1 and 2 (meters 1 and 2) are identical.

Engineering notes
To ensure correct data transmission, the pulse adapter should be installed in locations
where radio transmission is not impaired. In case of doubt, the transmission conditions
are to be tested with the PC radio module (refer to Data Sheet CE1N2876).
For immunity reasons, the total length of the connecting cable may not exceed 10 m.
Mounting notes
When installing the meter, insert 1 wire of the pulse adapter’s connecting cable and 1
wire of the meter’s connecting cable into one of the cable connectors supplied with the
unit.
Then, squeeze the connector with a pair of pliers.
This connection cannot be separated and offers degree of protection IP54.
Only for AEW36.2/DK:
With the housing cover open, insert the meter connecting cables with the O-ring from
the rear of the unit into the cable strain relief and connect the cables to the terminal
block. Then, close the housing.
Commissioning notes
The pulse adapter is to be programmed during installation. Enter the following data for
each channel:
−Type of pulse source (Reed switch, Reed switch with NAMUR, Open Collector, etc.)
per input
−Type of medium (gas, water, etc.) per input
−Physical variable (kWh, m3, etc.) per input
−Pulse valency per input
−Set day per input (1 set day per year)
−Meter readings when commissioning the pulse adapter, per input
−Meter number (identification number) per input
The parameters can be set wire-bound or via the integrated optical interface (IrDA):
For wired parameterization, a laptop (Windows 98 or higher), the ACT20 parameter
setting software, and the WFZ.MBM programming adapter are required.
Parameterization via the integrated optical interface (IrDA) is carried out by means of a
PDA.
For the pulse adapter to log on to the Siemeca™ AMR network, installation telegrams
must be triggered on the pulse adapter after parameterization:
On the first display level, press the button briefly a few times until you reach the M-bus
