ATTENTION!
Note that the limit switches of the motor only function
properly when the motor is correctly and completely
inserted into the shaft!
The arrows indicate the
direction of rotation of
the shaft.
The adjustment screws
next to it are
only responsible for
this one direction of
rotation.
Turn the adjusting
screw in the direction of
"minus
- the motor no longer
moves as far in this
direction.
Turn the adjusting screw
in the "plus" direction
- the motor moves
"jerkily" in this direction.
If the shutter does not stop before reaching the shutter box, stop it
with the STOP button on the control unit.
Then move the roller shutter back a little (approx. "half opening") and
turn the adjusting pin on the lower adjusting screw (3) a few turns in
the "-" direction.
Then move the shutter back in the OPEN direction and check that the
motor now stops before reaching the shutter box.
If necessary, move the roller shutter back a little again and reduce
the travel distance further by turning the adjustment screw in the "-"
direction.
Then move the shutter back in the OPEN direction and make the fine
adjustment.
To do this, turn in the "+" direction until the desired switch-off point is
reached.
Once the shutter has reached the desired opening height, remove the
adjustment tool.
Now allow the roller shutter to roll up and down completely several
times as a test. If the roller shutter stops at the set end points, the limit
switch setting is complete and the roller shutter box can be closed.
ATTENTION!
Please note that the motor is equipped with a thermal
protection switch and it may happen that the motor
switches off because it has reached a high temperature
after a few runs. In this case, the motor switches off
automatically for safety reasons.
After approx. 15-20 minutes cooling time the motor is
ready for operation again.
