16. Troubleshooting
16.5 Replacing the motor carriage
The instructions for "Disassembling the motor
carriage" can be downloaded from SOMMER at:
www.sommer.eu
If applicable, save the existing settings on the available
motor carriage via SOMlink and a WiFi-enabled device.
The settings can be transferred to the new motor
carriage later.
The new motor carriage is in delivery condition from the
factory. After replacing the motor carriage, make sure that
used accessories have been transferred to the new motor
carriage.
Commissioning must be repeated and the special
functions of the motor carriage must be reset, see
Chapter "9. Commissioning" and "10. Connections
and special functions of the motor carriage".
Handheld transmitters which are used must also be
reprogrammed, see Chapter "10.5 Programming the
transmitter". On the other hand, the transmitter does not
have to be programmed if the Memo accessory part has
already been used.
After successful commissioning, carry out a final test and
a function test, see Chapter "13. Function test and final
test".
INFORMATION
Save the existing settings of the motor
carriage with the help of SOMlink and a
WiFi-enabled device. After the new motor
carriage has been inserted, reinstall the
data.
