8. Luminous indications on led
Before activating the gear motor, familiarise yourself with messages indicated by the
red led on the head of the gear motor. This will allow you to check machine is
functioning properly or allow you to recognize possible anomalies.
LED function
Meaning
Constantly on
Motor in use. Limit switch programming active.
300ms on – 300ms off
Motor not programmed; limit switch programming
phase.
100ms on – 1sec off
Motor in electronical protection due to excessive
charge.
1sec on – 1sec off
Motor has regularly reached a limit stop but is still
connected to electricity supply.

9. Adjustment of the two stroke-ends
The gear motor allows you to adjust the stopping position of the blind at the desired
upper or lower points. Both stroke-ends are programmed in the same step, by using
the up and down control button and removing the plug located on the head unit of the
gear motor. The motor is factory set with a random stroke-end, i.e., not following any
particular logic. The programming procedure is simple and immediate; just strictly
follow the steps below:
1. Remove the plug (which looks like a screw) housed on the
head unit of the gear motor (see figure to the side). The plug
has a small magnet used to block the programming of the
two stroke-ends.
2. Operate the control button in one direction (either up or
down, it doesn't matter) and move the blind into the desired
position without ever reversing the direction of travel; there
can be intermediate stops as long as the next command is in
the same direction.
3. During the control action, the LED must be flashing. This means that the stroke-
ends are being programmed.
4. Operate the control button to reverse the direction of travel and move the blind to
the opposite desired position, again without ever reversing the direction of travel.
5. The LED must be flashing during the entire control phase.

6. Insert the plug into its position (see figure to the side). Now the programming is
finished.
7. Perform a complete stroke up and down of the blind and check that it stops in the
desired position. In this case the LED should remain steady-on during the entire
control phase.
8. Otherwise, repeat steps 1 to 6. The programming of the stroke-ends can be
repeated as often as necessary.
9. Perform a few maneuvers to check the blind's operation.
10. Troubleshooting
Please consult the following table for any eventual problems with function during
installation or normal use:
Problem
Possible cause
Solution
Gear motor doesn’t work.
No electricity supply for
feeder.
Check state of safety
switch.
Connecting cable not
connected or wire not
connected.
Check all electrical
connections of gear motor.
Feeder doesn’t deliver
foreseen tension (24V
).
Possible transformer
winding break down.
Led is lit but gear motor
doesn’t work.
Limit switch programming
is too close.
Loosen screw on head and
reset limit switch
programming.
Gear motor is damaged
due to a shock. Motor
connection has
unsoldered.
Send gear motor to a
Service Centre.
In spite of programming,
gear motor doesn’t get one
or both limit switches.
Programming hasn’t been
carried out correctly.
Repeat programming.
11. Indications for correct assembly
Check that curtain is perfectly spread without any folds or looseness.
Check that both up and down limit switches have reached the desired positions
Check that the gear motor support brackets are aligned and the four fixing screws
are firmly screwed into position
