Lath has broken off.
Repair system; then re-program limit po-
sitions.
Tubular drive overruns the limit position or
does not reach the set limit position.
A short circuit caused by dampness.
Repair electrical installation and re-pro-
gram limit positions.
External devices are connected to the
connecting cables of the tubular drive.
Check electrical installation; remove ex-
ternal devices; reset limit positions.
Due to long cable, L1 and N connection
have been reversed.
Swap L1 and N (N = blue, L1 = brown); re-
set limit positions.
Stops have broken off or one or more at-
tachments are broken.
Repair system; reset the tubular drive,
then re-program limit positions
Tubular drive does not retract after the
extended limit position has been set.
The tubular drive wrongly continues to ex-
tend and switches itself off automatically.
Both limit positions are now programmed
in the tubular drive.
Delete the limit positions, reprogram the
outer limit position, and retract immedi-
