Trouble
Possible causes
Solution
When the learning procedure is started, the
SET UP LED flashes but the automated system
does not perform any
manoeuvre
The STOP and FSW safety devices are ena-
bled also during the learning stage. Non-
connection or wrong connection prevents
the operator from working
Check the LEDs’ status following the
instructions of the “Inputs status LEDs”.
Check the connections shown in fig. 27
The automated system does not perform
any movement
STOP command enabled
The automated system opens the door but
does not close it
FSW safety devices engaged
The Fail-Safe function is enabled, but the NC
contact of the devices connected to the FSW
input does not open during test by the unit
before the manoeuvre is started
Learning is not finished correctly and the SET
UP LED flashes to signal a fault
The automated system frequently reverses
motion during the opening and/or closing
manoeuvre
The automated system detects that the door
movement is too difficult
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.
It is difficult to release the automated system
while the door is closed
Too much mechanical load on the release
system with the door closed
Run a new learning cycle and, when over,
lighten the closing thrust, commanding the
carriage to withdraw as described in para-
graph 11.2.
The SET UP LED flashes to signal a fault status The learning cycle did not finish
positively.
