During normal operation, the control unit constantly monitors the automation processes and is designed to indicate any faults that arise, by means of a
pre-set sequence of flashes emitted by the courtesy light and red led "L1" on the control unit (the diagnostics flashes always refer to the last action per-
formed by the automation). For an explanation of the number of flashes and associated cause, refer to Table 6 below:
Flashes
2 flashes - pause - 2 flashes
3 flashes - pause - 3 flashes
4 flashes - pause - 4 flashes
5 flashes - pause - 5 flashes
6 flashes - pause - 6 flashes
7 flashes - pause - 7 flashes

TABLE 6
Problem
During the Closing manoeuvre, the door stops and
inverts the current movement.
During the Opening or Closing manoeuvre the door
blocks suddenly and the control unit activates a brief
inversion of the manoeuvre in progress
During the Opening or Closing manoeuvre the door
blocks suddenly and the control unit activates a
Stop followed by a brief inversion of movement.
The automation does not respond to commands.
After a series of manoeuvres sent consecutively, the
automation is blocked.
The automation does not respond to commands.
Solution
This reaction is caused by the activation of a
specific pair of photocells in the system, on
detection of an obstacle. Therefore remove the
obstacle on the trajectory of these photocells.
The leafs are subject to increased friction due to
a sudden obstruction (gust of wind, vehicle, per-
son etc.). If adjustment to sensitivity is required,
refer to the Chapter "Adjustments and other
optional Functions".
A safety device installed (other than photocells,
such as sensitive edges) has detected a sudden
obstacle.
Therefore remove the obstacle.
There is a system configuration error. Delete the
entire memory of the control unit and repeat
installation.
The maximum admissible number of consecu-
tive manoeuvres has been exceeded, causing
excessive overheating. Wait for a few minutes to
enable the temperature to return below the max-
imum limit.
Error in internal electric circuits. Disconnect all
power circuits, wait a few seconds and then re-
connect. Retry a command; if the automation
does not respond this may indicate a serious
fault with the electrical board of the control unit
or motor wiring. Check and make replacements
as necessary.
