(refer to CV 38). The outputs can be digitally switched as continuous outputs. The address of the output is then automati-
cally the decoder address plus 1 (see CV 38).
You will find more options under CV 38 in the CV table.
3.12 Feedback via RailCom
Via the RailCom protocol the signal sends the following information to the digital command station:
- Aspect of the signal
- CV contents

4. Operation

4.1 Operating the signal
Press the appropriate button on the push-button panel (analogue use) or send an appropriate request / order to the address
of the signal (digital use). The signal drive turns now the signal with a realistic speed. This operation takes ca. 1.5 seconds.
During this operation, the signal saves another request / order, if this means another position and executes it after a short
cooling pause of ca. 0.5 secs.
4.2 Signal bouncing during downward movement
Viessmann semaphore signals, item 9500 and item 9501 allow the simulation of the typical bouncing effect for the down-
ward movement of the semaphore arms. Regarding the prototype semaphore signals you can observe a little movement
upward – caused by the unlocking mechanism – followed by the downward movement of the semaphore arm. When "falling
down", the weight of the semaphore arm leads to a bouncing movement.
For fast and simple use – even without a digital control system – three different motion sequences are stored in the memory
chip of the signal:
Profile 1 "weak bouncing" a slow and short movement upwards, a fast movement downwards with two soft bouncing
movements.
Profile 2 "high bouncing movements" a slow and short movement upwards, a faster movement downwards with two
considerable bouncing movements.
Profile 3 "no bouncing" a slow and short movement upwards, a fast movement downwards with no bouncing movements.
To select the motion sequence you prefer: Connect the 2 electrical power supply cables of the semaphore signal to the 2
power supply contacts of your transformer (e. g. item 5200).
Connect the two data line cables of the semaphore signal to each other and afterwards connect them both to one of the
two power supply contacts of the transformer. After about 1.5 seconds the semaphore arm starts moving in one of the three
possible motion sequences – up to five times. Having a new signal this means starting with profile 1.
By disconnecting the 2 data line cables from the transformer the motion sequence will be stored in the semaphore signal´s
memory chip.
Connecting the two data line cables to the transformer again means that after 1.5 seconds the semaphore arm will start
moving – now with the different motion sequence.
Disconnecting the data cables of the semaphore signal from the transformer means that now the motion sequence you
have just watched before is stored in the semaphore signal´s memory chip.
Repeat these steps until you have found the motion sequence 1, 2 or 3 you prefer.
Remove the 2 electrical power supply cables of your semaphore signal from the power supply of your transformer.
The motion sequence you have chosen is now stored in the memory chip of your semaphore signal – even without power
supply.
Now you can operate your semaphore on your layout in the chosen motion sequence mode. The selected profile is also
valid in digital mode.
The use of a digital control system allows the variation of even more settings by changing CVs: the velocity of the sema-
phore arm moving upwards, the velocity of the semaphore arm moving downwards and the amplitude of the bouncing
movements. For more details please read the detailed instructions on pages 10 and 11.

5. Maintenance

Caution:
Never dismantle the signal drive. This may result in damage or injury.
The Viessmann signal drive is maintenance-free.

6. Trouble-shooting

All Viessmann products are produced with high quality standards and are checked before deliv ery. Should a fault occur
nonwithstanding, please first check the power supply (dirty tracks, operating voltage). Subsequently, we list some other
possibilities:
