What to do if... ?

...the motor fails to start?
Possible cause:
◆ The mains voltage is not available.
Solution:
◆ Check the power with a meter to ensure that the supply voltage (230 V) is available
and check the wiring.
◆ Observe especially the information relating to impermissible connection types.
...The tubular motor stops after a short period of time during the
configuration and test procedures?
Possible cause:
◆ The adapter (10) may have slipped off of the limit ring (18) on the drive head (12).
Solution:
◆ Check that the adapter (10) sits flush with the drive head (12) and is fully inserted
into the rotating union (5).
◆ Slide the adapter (10) back so that it is flush with the drive head (12) and slide the
rotating union (5) fully onto the adapter (10), see Fig. . Re-adjust the end points
if necessary, see page 44.
...Automatic adjustment of the lower end point does not work.
Possible cause:
◆ The catch (8) is mounted without the freewheel mechanism.
Solution:
◆ Configure the lower end point manually, see pages 48 and 49.
...The tubular motor stops between the two end points during normal
operation?
Possible cause 1:
◆ The bearing capsule (4) may not be secured with a screw to the rotating union (5)
(see Fig. ), causing the rotating union (5) to slip from the motor and the adapter
(10) to come away from the limit ring (18) on the drive head (12).
Solution 1:
◆ Check for correct fitting of the bearing capsule (4) and the adapter (10). Use a
self-locking bolt to secure the bearing capsule (4) to the rotating union (5) and
remount the motor in accordance with the information on pages 36 - 41.
Possible cause 2:
◆ The thermal protection system has triggered.
Solution 2:
◆ Wait approx. 20 minutes until the motor has cooled down.
...The roller shutters stop during upward or downward travel?
Possible cause:
◆ Iced-up roller shutters or obstacle on the guide rail.
Solution:
◆ Move the roller shutters a short distance in the respective opposite direction.
◆ Rectify iced-up roller shutters or obstacle.
