Solution
Check the LEDs ' status following the
instructions of the "Inputs status LEDs".
Check the connections shown in fig. 27
Check the balance of the door and
make sure that it moves without too much
friction. Move the door manually, using the
rod fitting on the door, and check if the mo-
vement is smooth and does not require too
much traction or thrust.
Run a new learning cycle and, when over,
lighten the closing thrust, commanding the
carriage to withdraw as described in para-
graph 11.2.
Run a new learning cycle
