DEFAULT SETTING
The limits of the shutter motor have been set to a short length of travel (small window) and must be merely adjusted to suit actual requirements.
See under Point 3: Setting the limits
The radio remote control (hand-held transmitter) has already been programmed at the factory. Should it operate in the reverse direction i.e. button
for upward direction moves shutter downwards, this can be remedied.
See under: Programming first radio remote control.
3. Setting the limits “Open” and “Closed” position
The bottom adjusting screw is always for the upper limit and the upper is
always for the lower limit, no matter whether the motor is pushed into
the shaft from the right or the left.
My roller shutter box is:
A:
A left-handed installation. I look into the box and the limit switch of
the motor is on the left
(see Fig. L1)

B:

PLEASE READ THROUGH THE FOLLOWING INSTRUCTIONS
CAREFULLY BEFORE SETTING THE LIMITS.
Press the DOWN / UP button (remote control or switch) and let the
shutter drive move in a downward direction until it cuts off automatically
and then (and only then!) ......
4. FASTEN SHUTTER ARMOURING (SLATS) TO
SHAFT.
Limit at bottom is now set. If necessary make final adjustment with
adjustment screw.Allow drive to run upwards. If it switches off too early
the bottom adjusting screw must be adjusted in the plus direction.
Each full turn of this screw extends the travel path by about 40° of one
turn of the motor. The motor should stop just a few inches below the
window frame. If not the adjusting screw should be adjusted in the
minus direction. After this the drive must be driven back a little and then
up again to check the result.
It is possible that the drive will switch itself off after several trips because
it has reached a temperature which is too high. Howevere after 15 – 20
minutes cooling time it will be ready to operate again.
Please note that the limit switches of the drive only function
properly if the drive has been installed correctly and is completely
within the shaft.

Advice: In order to fix the roller shutter hangers to the shaft,
ONLY use short fixing screws. If the screws are too long damage
may occur to the motor. The recommended fixing method for the
hangers is without screws by means of spring band loops (which
are hooked on).
