INSTALLATION INSTRUCTIONS
Special case: Roller shutter rolls down in front of motor + shaft
If the roller shutter curtain rolls in front of the motor and shaft, the responsibilities of the limit switch screws for the upper and lower end positions are reversed.
See illustration of left-right installation on page 11: upper end position > lower end position / lower end position > upper end position.
1. Setting the lower end position
Do not fasten the roller shutter curtain!
•
Detach all suspension springs from the roller shutter shaft!
Move the motor + shaft in the downward direction until the lower limit switch-off occurs automatically
•
and the motor stops.
Move motor + shaft upwards.
•
While the motor is moving upwards, turn the adjustment pin on the limit switch screw for the upper limit
position in the MINUS direction (up to 100 turns, depending on the motor type) until the motor switches
off after approx. 4 turns.
This prevents the roller shutter from being pulled out of the guide rails when the upper end position is set.
Move motor + shaft in downward direction to the lower end position until the motor stops automatically.
•
If the shaft has to be turned a little to hook in the suspension springs, use the adjustment pin on the
•
limit switch screw for the lower end position in the PLUS direction. This causes the motor to turn the shaft
stepwise. The rectangular openings in the shaft for hooking in the suspension springs should point forward
and be easily accessible.
Hang the roller shutter curtain on the roller shutter shaft using the suspension springs.
•
2. Setting the upper end position
Allow the motor + roller shutter to move upwards until the motor stops automatically at the previously set
•
upper end position.
To set the upper end position, turn the adjustment pin on the limit switch screw for the upper end position
•
in the PLUS direction to raise the motor + roller shutter further. The upper end position should be that the
roller shutter stops approx. 3 cm before the roller shutter box. Reason is the expansion of the roller shutter
due to the temperature difference in summer and winter.
After setting the end positions, lower and raise the motor + shutter to check the set end positions.
•
Adjustment pin
is required
Note heat generation
The end position setting without
shutter curtain load leads to more
heat generation in the motor. This
is normal behavior and does not
result in damage to the motor. If
the motor heats up too much, the
thermal protection switch of the motor
is automatically triggered. After a
cooling phase of at least 10 minutes,
the motor is ready for operation again.
