The running time is the length of time that the drive stays
on.
If the "S" button is held down for longer than 3 seconds,
will appear on the display (Fig. 14, standard value
1 minute and 30 seconds). The running time can now
be changed using the
and
buttons. After the run-
ning time has elapsed, electrical power is removed from
the drive, and reversal is carried out if active. By press-
ing the "S" button repeatedly, you enter the "Set reversal
time" mode. This is shown by a , and the running time
that has been set is saved at the same time. The value for
the reversal time can be varied between "01" and "99"
(Fig. 13).
Changing the factory-set running time/reversal time
Fig. 14
By pressing the " " button, the reversal time is switched
off (
, Fig. 13). The maximum reversal time ("99" on
the display) corresponds to about 3.2 seconds. Press the
"S" button again to return to operating mode. If the rever-
sal time is active, then after the running time has elapsed,
the drive is operated in the "UP" direction for the duration
of the set reversal time. Depending on the setting and on
the speed of the drive, the first slats of the roller shutter
are then cleared again to provide ventilation, for example.
When the set running time has completely elapsed, the
roller shutter can be closed completely by hand.

Problem
Cause
Remedy
The roller shutter moves downwards about 15
minutes after it has been opened.
The set twilight value has been reached, or the
sensor is covered.
Check the twilight value and the position of the
sensor on the window. It may have become
detached from the pane.
The U26 does not carry out the set switching
commands, or does so after a delay.
The time is set to manual or holiday operation.
Put the time into "automatic mode".
The sun and twilight parameters that have been
set cannot be changed, or are not displayed.
A sensor is not inserted, or else either the sen-
sor or its connecting cable is faulty.
Check the sensor, the sensor cable and the
connecting plug.
