starts, the SET UP LED flashes but the
automated system does not perform
any movement
The STOP and FSW safety devices are
active also during the learning phase. Their
missing or incorrect connection inhibits
the operator
Check the LEDs status observing the
indications of the table “Input status
LEDs” on page 8. Check the connections
shown in fig. 28.
The automated system does not perform
any movement
The STOP command is active
The automated system opens the door
but it does not perform the re-closure
The FSW safety devices are engaged.
The Fail-Safe function is active, but the
NC contact of the devices connected
to the FSW input does not open during
the test performed by the unit before
starting the movement
The learning procedure has not ended
successfully and the SET UP LED flashes
thus signalling a fault
The automated system performs frequent
reversals of movement during the
opening and/or closing movement
-The automated system detects an
excessive difficult movement of the
door
–If you are using the manual force
adjustment, the set thrust could be
insufficient
Check the door balance and if the door
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 excessive
drive or thrust. Adjust the balance of
the system so that the released door
cannot move. Execute a new learning
procedure.
The automated system is difficult to
release when the door is closed
The mechanical load on the release
system is too high when the door is
closed
Execute a new learning cycle and
then decrease the thrust at closure by
commanding a back movement of
the carriage as described in paragraph
11.2.
The SET UP LED flashes thus signalling the
fault status
The learning cycle has not ended
successfully
Execute a new learning cycle
18. TROUBLESHOOTING
The learning cycle has never been
performed.
