When the window is closed, check that the chain terminal protrudes completely from the
actuator body by at least a couple millimetres; this ensures that the window is closed well
and the seal is compressed properly, otherwise the window may not be completely closed
arising the risk of possible leakages.
Check also that the attachments and support brackets are solidly joined to the window and
the screws are tightened properly.
The use of self-threading or self-drilling screws on aluminium windows is not
recommended at all, since they can tear the profile after a few manoeuvres; use metric
screws with threaded inserts instead
(see instructions in paragraph 9.3)

If there are any problems during installation or operation of the machines, please take a
look to the possible causes listed below:
WITH RED LED
No. of
Flashes
Type of Error
Possible Solution
1
Current error:
The actuator has detected an
overcurrent in the motor.
Check that there are no obstacles preventing
the actuator from completing its stroke. Check
that the actuator is installed correctly.
2
Communication error:
Communication between the
devices is interrupted, or the
devices being used have
undergone the RESET procedure
separately.
Check the condition of the connection cables,
and repeat the RESET procedure if necessary.
3
Electro-lock error
Check the electro-lock.
4
Contrasting Dip-switch settings:
The devices connected to one
another have conflicting Dip-switch
settings.
Check the settings of the various Dip-switches.
5
RESET Procedure error:
The RESET procedure was not
completed successfully or was
interrupted.
Repeat the RESET procedure.
6
Wiring error:
The power supply cables of the
devices configured in Syncro³
modus are inverted.
Check and correct the wiring.
7
Encoder error:
The internal encoder had a
counting error.
Repeat the RESET procedure.
8
Electric power supply error:
The power supply voltage is
outside the permitted range or is
unstable.
Check the electrical contacts at the ends of the
actuator cable and ensure that the power
supply is correct.
9
Chain alignment error:
The misalignment of the chain
Repeat the RESET procedure.

terminal positions on devices
connected in a Syncro
configuration exceeds the
maximum amount allowed.
10
Memory error:
The internal memory write process
failed.
Repeat the RESET procedure.
11
Connection error:
A RESET procedure is being
started with actuators different than
Syncro³, K-LOCK or AUX
Check the type of actuators chosen for the
system. Repeat the RESET procedure.
WITH GREEN LED
LED Status
Meaning
STEADY-ON
Device powered correctly.
The device has correctly performed a chain re- entry stroke, completing
the operation by writing the memory; or it is still in motion.
FLASHING
Device powered correctly. The device executed an outgoing stroke of
the chain correctly. The number of flashes indicates the number
previously assigned to the device during the RESET procedure.
WITH ORANGE LED
LED Status
Meaning
STEADY-ON
Duration < 0.5 sec.
Internal memory write process in progress.
STEADY-ON
RESET Procedure in progress.
STEADY-ON for 3
sec.
Overlap acquisition procedure finished correctly.
FLASHING
RESET Procedure finished correctly. The number of flashes indicates
the number assigned to the device in a configuration with several
devices.
11. Checking for correct assembly
Check if the window is perfectly closed at corners and that there are no obstacles
caused by incorrect positioning during assembly.
Check when the window frame is closed if the chain terminal is at least a few
millimetres away from the actuator body. This will ensure the window is properly closed
and seals are correctly compressed. In the event that this should not be the case there
is no guarantee that the window is closed correctly.
Check if hinges and support brackets are aligned to each other, tightened to the
window frame and screws correctly fixed.
Check if the window reaches the desired position according to the stroke-end selected.
In the presence of an electro-lock, check if at the end of the actuator closing stroke, the
K-LOCK activates and it’s closing time is about 4 seconds.
