5. Mounting
1) Cut a 30 mm x 15 mm hole at the installation spot. In a first step you need to drill 4 holes of 6 mm diameter each into the corners.
Use the pattern which is shown in fig. 4.
2) The signal's connection cables have to be inserted into the hole first. After that put the signal with the drive first into that hole.
3) Attach the signal to the baseboard with the enclosed screws.
6. Connections
Now make the electrical connection as per fig. 6 or 8. For the signification of the cable colours refer to fig. 5.
For the signal light, we recommend a separate transformer. This will prevent flickering of the lights due to high consumption of
the drive. Connect the signal light to the transformer via the yellow cable with black marker and the brown cable with the diode.
Direct current: Connect both yellow cables to the negative pole of the transfomer.
6.1 Analogue control
The conventional wiring is shown in fig. 6. It shows how you can connect the three-aspect form signals to a push-button panel
(e. g. item 5546 without feedback or item 5548 with feedback).
6.2 Digital control
The semaphore home signals can also be operated with a digital system. Refer to fig. 8 for the correct wiring. When connecting
e. g. to the Viessmann Motorola digital decoder, item 5211 (MM) you have to make sure to connect, besides the blue cables for
signal control, also the yellow cable (without marker) for power supply. To digitally switch a three-aspect signal, you need 11/2
output groups of a digital decoder. The remaining output socket can be used for another three-aspect signal (together with another
output group) or for an uncoupling track.
Viessmann semaphore signals with 2 drive units need positive switching pulses. This is why you cannot offhand switch the signals
with all digital decoders (e. g. Lenz, Trix etc.) as these supply negative pulses. Viessmann is, therefore, supplying decoders
providing positive switching pulses for all digital systems!
The Motorola digital decoder (item 5211, 4-fold) is compatible with Märklin-Motorola-format. The 4-fold multi protocol decoder,
item 5280 as a switching and turnout deocder is compatible to all DCC digital systems, e. g. Digital plus (Lenz), Arnold Digital,
Roco Digital, Fleischmann Twin Center, Digitrax, Uhlenbrock Intellibox, Tillig Digital, Viessmann Commander etc. and supports
the Märklin-Motorola format as well as the DCC protocol.
7. Trouble-shooting
All Viessmann products are produced with high quality standards and are checked before delivery. Should a fault occur notwith-
standing, you can do a first check. Begin with checking the power supply.
1. Disk or arms are not straight:
Set the signal to the Vr0 aspect and adjust the disk or arm back into the straight position very carefully! Both can be shifted on
their axles.
2. The switching sound of the signal drive can be heard, but disk or arm do not move or move only partially.
Move the lifting rod very carefully slightly up and down (if necessary detach the lifting rod from the bar lever and check if bar
mechanics can be moved without resistance).
3. The signal lamps illuminate and the power supply doubtlessly is working fine, however the signal does not switch.
Possible reason: The inner limit switch has not got any contact.
Switch off the electrical power! Then move up the switch contact by means of a pin or a thin wire (refer to fig. 7).
If the product is damaged please contact our service department (service@viessmann-modell.com). Please send the item to the
Viessmann service department for check resp. repair only after consultation
