20. Repairs

• The FTS is not working:
• Check the power supply (circuit breaker + control box fuse)
• Check for the electric bridge between terminals 13
and 16 of the control box, or make sure that the safety
contact is properly closed.
• Press the end limit setting push buttons on both
actuators, to put them into setting position (push
buttons engaged), if they are at the end limit in both
directions.
• The FTS stops during a manoeuvre and will not work:
• If the thermal safety on one of the actuators has been
triggered, you need to wait around 1/2 hour before
operating the FTS again.
• If the problem persists, disconnect the actuators from
the control box to test them with the setting tool.
• Check the power supply (circuit breaker + control box
fuse).
• if the LED turned on or blink, you need to wait the
FTS Box temperature decrease
• The system only starts after 2 or 3 presses on the control
system:
• This problem is due to mechanical clearance on a
load-bearing component; indeed the time between
the request being made on the control system and
the actuator being released from its end limit must not
exceed 1.1 second.
• The fabric winds onto the tube in a spiral:
• Make sure that the edges of the fabric are
perpendicular to the roller tube and the load bar.
• Make sure that the straps are perpendicular to the
roller tube and the load bar.
• The fabric unwinds jerkily and the actuators seem to be
abnormally forced (noisy):
• Reduce the dynamic tension on the potentiometer
(13).
• Make sure that the guidance system is not generating
excessive stress.
• Whenever it is stopped, the system seems to strain the
structure abnormally:
• Reduce the end tension on the potentiometer (14).
• Make sure that the actuators used are those
recommended on our charts.
• For any questions/problems, please contact Somfy.
