WHAT TO DO
Initialization error
1 BL
OFF OFF OFF ON
An error occurred during initialisation, in
particular, the measured opening quota is
too low. Check the encoder, the
connection between the encoder and
mother boards. Make sure the transit area
is free of obstacles. In the event of
electronic lock, check correct operations.
Door blocked
error
2 BL
OFF OFF ON OFF
The door cannot open. Make sure there
are no obstacles in the transit area and that
there are no locks (electric or manual) that
block the door.
Anti-crushing in
opening error
3 BL
OFF OFF ON ON
After three opening and anti-crushing
detection attempts. Make sure there are no
obstacles in the transit area. Make sure that
the anti-crushing sensitivity in opening is
not too low. Check the encoder, the
connection between the encoder and
mother boards.
Anti-crushing in
closing error
4 BL
OFF ON OFF OFF
After three closing and anti-crushing
detection attempts. Make sure there are no
obstacles in the transit area. Make sure that
the anti-crushing sensitivity in opening is
not too low. Check the encoder, the
connection between the encoder and
mother boards.
Inversion error
5 BL
OFF ON OFF ON
An inversion error of the movement
between the encoder and motor was
detected. Make sure that the motor is
correctly connected
Overcurrent
error
6
BL ON ON ON OFF
Motor overload detected. Make sure there
are no short circuits on the motor power
cord. Check the motor and replace if
necessary.
Encoder error
7 BL
OFF ON ON ON
Encoder malfunction detected. Check the
encoder, the connection between the
encoder and mother boards.
