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
enabled 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
movement 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
paragraph 11.2.
The SET UP LED flashes to signal a fault
status
The learning cycle did not finish
positively.
Run a new learning cycle
