Warranty; Technical Data - Viessmann 9500 Bedienungsanleitung

6.1 Signal is getting very hot and / or starts to smoke.
- Disconnect the system from the mains immediately!
- Check if the wiring was made correctly as shown in this manual.
- Check the electronics housing for damage.
- Possible cause: Short circuit. The signal was not connected correctly.
- Possible cause: The decoder insulation in the lead wire is damaged or has been in contact with metal parts.
6.2 Signal drive moves in the wrong direction.
- Check the wiring of the control cables as per fig. 8 or fig 8.1.
- Check if CV 36 is programmed correctly.
6.3 Signal drive does not operate.
- First check if the drive works in analogue mode. If it does the most likely cause is an error in the address or protocol
programming. Repeat them and, if necessary, reset the decoder to default values (program CV 8 to value 8).
6.4 Unexpected signal bouncing at downward movement.
- This is typical for the prototype and, therefore, also a part of realistic Viessmann model semaphores. The standard factory
setting for Viessmann semaphore signals is motion sequence 1 "weak bouncing". To change this please select a different
operation mode: either as described on page 13 or using a digital control system by changing CVs (see pages 10 and
11).
6.5 Signal drive seemingly does not function at the programming output
- Some command stations may not be able to recognise the signal drive at all when connected to the programming output
and will give an error message. This is due to the low current drawn by the signal drive. In such cases, connect an
incandescent lamp with ca. 20 to 30 mA current consumption at 16 V to the programming output parallel to the signal
drive. This increases the load current needed for the command station to recognise a decoder.
Should writing and reading CVs result in error messages, this is also due to the low current consumption of the so-called
acknowledge pulses (confirmation pulses).
Connect an incandescent lamp with ca. 20 to 30 mA current consumption at 16 V to the switching contacts (fig. 7). This
increases the current and enables writing and reading.
Please refer to chapter 7 "Warranty" if you cannot find the cause of the failure and, therefore, cannot rectify it.

7. Warranty

Each model is tested as to its full functionality prior to delivery. The warranty period is 2 years starting on the date of
purchase. Should a fault occur during this period please contact our service department (service@viessmann-modell.com).
Please send the item to the Viessmann service department for check and repair only after consultation. If we find a material
or production fault to be the cause of the failure the item will be repaired free of charge or replaced. Expressively excluded
from any warranty claims and liability are damages of the item and consequential damages due to inappropriate handling,
disregarding the instructions of this manual, inappropriate use of the model, unauthorized disassembling, construction
modifications and use of force, overheating and similar.
