WHAT TO DO IF...
(Troubleshooting guide)
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 flashing 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 5

Problem
During the
Opening
or
Closing
manoeuvre the door
blocks or inverts the manoeuvre in progress.
• During the
Opening
or
Closing
manoeuvre the
door blocks suddenly and the control unit activates
a total inversion of the manoeuvre in progress to
reach the limit switch.
Note
– During this inversion, if the leaf detects a sec-
ond obstacle, it inverts movement again, and if a
third obstacle is detected the gate blocks movement
without reaching the travel limit.
(The automation is factory-set not to exceed three
attempts).
During the
Opening
or
Closing
manoeuvre the gate
leaf 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.
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 leaf is subject to increased friction due to a
sudden obstruction (a strong gust of wind, vehi-
cle, person 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. Ensure cor-
rect insertion of the jumper “Sel” on the control
unit. Then 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.
Error in “Bus” internal electric circuits. Check
operation of the connected devices one by one.
These may be short circuited or malfunctioning.
