Remedy error. Further movement after push of a
button.
Remove collision. Further movement after push of
a button.
Check the connection line of the lifting module
and plug-in contact. Check / observe the height
difference. A lifting module may not move any more or
asynchronous ==> decommission and/or remove the
table top or assembly. Otherwise, contact the service.
Make sure that all connected control units are of the
same type.
