15. Meaning of the LED flashing mode
The LED can be seen on the electronic board after removing the closure plug. In some
cases it flashes in different ways depending on the signal it is emitting; the different
flashing modes indicate the precise behavior of the actuator during the programming of the
machine, radio remote control or rain sensor.
The table below summarizes the meaning of the LED flashing mode.

16. Checking for correct assembly
Check that the window has closed completely, even at the corners, and check
there are no obstacles caused by assembly in the wrong position.
Check that when the window frame is closed, the chain terminal is at least a
couple of millimetres distant from the actuator body. This will ensure correct
closure of the window with correct pressure on the weather stripping. If the chain
terminal is not positioned as stated there is no guarantee the window will close
correctly.
Check that all attachments and support brackets are tightly fixed to the window
frame and that all screws are correctly tightened.
Check that the window moves to the desired position in accordance with the limit
switch selected.
