Signal Bus - Viessmann 5229 Bedienungsanleitung

The previous signal respectively its control module, items 5224 or 5229 must get information by the signal bus, if it has
to indicate proceed slowly respectively a lower speed. Therefore, the permissible track speed allowed from this specific
main signal on must be programmed in the control module.
The highest speed that is to be indicated is 15 (= 150 km/h). The highest permissible track speed is 160 km/h on a normal
railway track (automatic train control ATC/ PZB90). It must not be indicated by a signal. Higher speeds are only allowed
on tracks equipped with the continuous train control system LZB. It requires no special signalling.
The adjustment:
Add up the individual speeds adjustable by the DIP-switch, until you reach the required speed. Begin with the highest
value.
Example: Line speed 130 km/h
DIP-switch 5 on "on" = 80 km/h
DIP-switch 6 on "on" = 40 km/h
DIP-switch 8 on "on" = 10 km/h
4.3 Digital mode of control module
The module requires in both Märklin Motorola and NMRA DCC format up to four successive addresses. If two or more
addresses are required (for a multi-aspect signal) the first one is always an even number.
Up to five external contacts or push-buttons can be connected for switching the signal (either manually or by the train).
The first four are for "red", "green", "green-yellow" and "shunting". The fifth is called "braking" and is intended for the
brake generator and triggers the change over from normal supply from the Command station or booster to supply via
the brake generator. Without brake generator the interruption of the track power becomes effective immediately if the
signal shows "stop". The switching of the track power is done by the Viessmann relay for train control, item 5228 (see
also manual for item 5228).
4.4 Programming for Märklin Motorola
To enter an address for Märklin Motorola, push and hold the button "address" until the red control LED starts to blink. The
control module indicates this status by slow blinking of the control LED. Now you may enter a command with the keyboard
with the address to be used for this signal. Up to 320 Motorola addresses are possible. The module waits for the first valid
switch-command and takes its address as its own. The now dark LED indicates the completion of this process and the
signal shows the appropriate aspect.
4.5 Programming (NMRA-DCC)
To enter an address for DCC, push the button "address" until the red control LED starts to blink. A second push of the
button takes the module to the DCC programming mode. The LED indicates this status by fast blinking.
Now you may send a DCC command. Up to 2048 addresses are possible. The module waits for the first valid switch-
command and takes its address as its own. The now dark LED indicates the completion of this process and the signal
shows the appropriate aspect.
When configuring the module for a multi-aspect signal the module accepts an uneven digital address as its first and the
subsequent even number as the second address. Therefore, the command for a multi-aspect signal for address 001 or
for address 002 would programme the module in both cases to addresses 001 and 002. The combination of addresses
002 and 003 is not permitted, since this could easily lead to overlaps with the addresses of other decoders.
4.6 Finishing the address adjustment
The control module finishes automatically the programming of the address after the reception of a valid digital command. If
you want to quit the address programming mode without any change, push the key "address" a third time.
4.7 Factroy setting
Push the key "address", hold it pushed down and switch on the operating voltage.
The factory setting of the module is the Motorola address 1 and options corresponding to the possibilities of the DIP-
switches.

5. Signal bus

In modern signal systems the individual signals are dependant on each other respectively the aspect of the signal is in-
fluenced by the following signal. In order to simulate this interdependence, the signals are connected via the Viessmann
signal bus. The signal bus is a separate data communication by 2 extra cables and works against the direction of travel.
The signal bus is integrated in the modules, items 5224 and 5229.
Important: The signal bus does not require a digital system. It works in the same manner and without any restrictions on
analogue layouts!
