Viessmann 9500 Bedienungsanleitung Seite 9

The address is established as described below. Write the address value directly into CV 1 if you wish to assign an address
between 1 and 255. Set CV 9 to 0. Higher addresses than 255 have to be split into the MSB and the LSB: Divide the desired
address by 256 and determine the result without decimal points as well as the remainder.
Examples you will find at page 13.
Further programming options are listed in the CV table. You may also set the desired digital protocol in CV 40.
The decoder will respond to commands of the programming output of a DCC compatible command station regardless of
the set protocol.
3.6 Configure with Motorola central units
To use the signal in a digital environment, you have to assign a digital address at first. To control the signal with a Motorola
system, observe the following instructions:
1. Switch off the digital system (e. g. emergency off). There must not be any power at the rails.
2. Connect only the blue wire with the green marker and the power supply wires of the signal (brown and yellow, fig. 7) to
the rails – i. e. only 3 cables!
3. Switch on the digital system.
4. Connect the so far open second blue wire (red marker) to the track signal, too (fig. 7).
5. Use the digital command station to send a switching request for the desired Motorola address. The signal receives the
request, registers the address as its own and as a receipt, it switches the signal.
The decoder is now ready to be used with the new digital address. If you want to change the address, you just have to
repeat the described procedure.
Notice: If you use a multi protocol digital command station, which is able to use the Motorola as well as the DCC-system
simultaneously, it is recommended to program the signal on a DCC address. In Motorola format the address range is limited
to only 320 addresses.
3.7 Digital mode with a locomotive address
Proceed as follows if you wish to program the decoder to a locomotive address:
Decide which digital system you are going to use. Proceed as described in points 1 – 4 of the chapters "Configurations with
DCC command stations" or "Configuration with Motorola central units". Set all locomotives to speed step 0 if your command
station does not do that automatically.
Instead of the accessory command as per point 5 send a locomotive driving command to the address to be assigned to this
drive. Turn up the throttle in order to send a speed command greater than 0. This address corresponds to the typical group
address of an accessory decoder with four double-outputs. Select one of the functions F1 – F4 of this locomotive address,
which assigns the functions of this address to the signal drive. Thus you may control four signals with one locomotive ad-
dress similar to a decoder for four accessories. The address range is limited to addresses from 1 – 99.
3.8 Programming with POM
The decoder supports programming of all CVs via POM ("Programming on the Main"). Since not all command stations sup-
port POM for accessory decoders you may also set the decoder to respond to the locomotive POM mode. Enter the value
80 in CV 8 of the address 9999. Then the signal decoder responds to normal POM commands for locomotives under the
respective address. For safety you should first edit CV 1 and then CV 9, even if the value of CV 9 did not change.
Note:
If the switch direction is inverted caused by the properties of your DCC/MM command station you can correct this according
to fig. 8.1 or change by programming the CV 36 on value 1.
Please be careful to avoid inadvertent programming of other locomotives with the same address. Remove locomotives
with the same address from the track or disconnect power to such track sections. If RailCom is active the corresponding
feedback will be sent to the command station.
3.9 Switch outputs
The switch outputs can be configured to suit various functionalities (CV 38). The outputs are intended for relays, but can
also power small loads such as LEDs.
3.10 Feedback via relays
The signal is equipped with a transistor-driven output, which is able to indicate the position of the turnout. This output is
used to operate latching relays. The contact is turned on for ca. 250 ms, when the signal reaches its respective end position.
With these contacts (soldering pads on the back of the casing), you can use the information about the position of the signal
to switch off the rail voltage, or in other control systems, for example a brake generator.
Due to the low maximum load of the contacts and the short pulse length, it is important to use a relay (e. g. the Viessmann
electronic relay, item 5552) as shown in fig. 9.
3.11 Other functions of the switching outputs
Besides the switching pulse already described, the outputs can also be set to continuous mode with various commands
