FTS system operating principle
The final tension is always applied after the actuators have stopped at the end limits or after a "STOP" command has been
made. The final tension will vary in strength according to the temperature of the actuators.
To achieve the optimum setting, first set the potentiometer (
XIV)
to 0, then gradually increase the potentiometer value until
the fabric is correctly tensioned.
N.B.: the tension of the fabric will vary when the actuators are hot (the "thermal time" of the FTS actuators is on average 8
minutes for FTS LT50 actuators and 7 minutes for FTS LT60 actuators).
Note:
This setting must be made after the end stops of the FTS actuators have been set as well as the symmetrical / asymmetric
tension.

High stress on the structure!
Request fabric feed-out/in, followed by a "stop" order:
•
the system will stop, and then re-tension the fabric.
Perform various tests, gradually increasing the potentiometer value
(
XIV)
, until you obtain a correct fabric tension.
