supply voltage (230 V) is available and check the
wiring.
Observe especially the information relating to
impermissible connection types.
...the wiring is incorrect?
Possible cause:
The control lines are mixed up.
Solution:
Disconnect the lead from the mains and ex-

and
L1
.
12. What to do if... ?
...The tubular motor stops between the two end
points during normal operation?
Possible cause 1:
The roller capsule
(4)
may not be secured with a
screw to the winding shaft
(5)
(see figure
[ 20 ]
),
causing the winding shaft
(5)
to slip from the mo-
tor and the adapter
(10)
to come away from the
magnetic ring
(18)
.
Solution 1:
Check for correct fitting of the roller capsule
(4)
and adapter
(10)
. Use a self-locking bolt to secure
the roller capsule
(4)
to the winding shaft
(5)
and
remount the motor in accordance with the infor-
mation on pages 11 - 18.
Possible cause 2:
The thermal protection system has triggered.
Solution 2:
Wait approx. 20 minutes until the motor has
cooled down.
...The tubular motor stops after a short period of
time during the setting and test procedures?
Possible cause:
The adapter
(10)
may have slipped off the mag-
netic 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 winding
shaft
(5)
.
Slide the adapter
(10)
back so that it is flush with
the drive head
(12)
and slide the winding shaft
(5)
fully onto the adapter
(10)
, see figures
. Re-
adjust the end points if necessary, see page 23.
...The roller shutter stops during upward or
downward travel?
Possible cause:
Iced-up/jammed roller shutter or obstacle on the
guide rail.
Solution:
Manually move the roller shutter a short distance
in the respective opposite direction.
Rectify the iced-up roller shutter or obstacle.
i
...The roller shutter judders /stops during down-
ward travel although there is no obstacle?
Possible cause 1:
The roller shutter may be too light. It must run
easily and have an appropriate drop weight.
Solution 1:
Place weight on the lowest roller shutter slat
(e.g. with a flat bar).
Possible cause 2:
The winding shaft may be installed very tightly.
Solution 2:
Loosen the roller capsule and insert it approx.
2-3 mm further into the winding shaft and fix the
capsule again with a screw.
