FTS system operating principle
This setting is entirely linked to the way the system has been fitted.
Symmetrical tension of the fabric should be selected for horizontal installations.
•
Asymmetric tension of the fabric should be selected for certain installations to fit
•
special cases,
that have the prior approval of Somfy's technical services
.

Symmetric tensioning of the fabric:
A) When the dipswitches (
XII
) are in the ON/ON position, the
braking effect is active, for the two actuators (fabric actuator
and strap actuator), according to the potentiometer setting
(
XIII)
.
This is the factory setting for standard cases.
B) When the dipswitches (
XII
) are in the OFF/OFF position,
the braking effect is in the minimum range for the two
actuators (fabric and strap actuators).
This setting requires prior approval by Somfy's technical
services.
Asymmetric tension of the fabric, fabric actuator at the
top:
When the dipswitches (
XII
) are in the ON/OFF position, the
braking effect is active for the fabric actuator according to the
potentiometer setting (
XIII)
and the braking effect is at the
minimum setting for the strap actuator.
This type of installation requires prior approval by
Somfy's technical services.
Asymmetric tension of the fabric, fabric actuator at the
bottom:
When the dipswitches (
XII
) are in the OFF/ON position, the
braking effect is active for the strap actuator according to the
potentiometer setting (
XIII)
and the braking effect for the
fabric actuator
is at the minimum setting.
This type of installation requires prior approval by
Somfy's technical services.
