A.3 - SEMIAUTOMATIC Programming of the UP (“0”) and DOWN (“1”) limit switches
NOTES AND WARNINGS
• Use this procedure solely for roller shutters with mechanical Up “0” limit switch stop.
•
Programme the UP limit switch (0) FIRST.
• the down limit switch (1) is NOT memorised if it is within 120° with respect to the UP limit switch (0).
• Once the limit switches have been programmed, the Up movement will be limited by the impact of the roller shutter against the mechanical locking device (box) pre-
sent in the Up limit switch “0”. Periodically, the height of this limit switch will be automatically updated by the “Automatic limit switch update” function (paragraph 5.2).
Conversely, the Down movement will be limited by the Lower limit switch “1” (limit switch set by the installer at a desired point).

A.4 - Adjusting the motor’s sensitivity to obstacles
NOTES AND WARNINGS
• Use this procedure to activate, adjust or deactivate the safety system that:
a
) detects the presence of an obstacle along the travel of the roller shutter;
b
) reduces the
motor tension on the roller shutter when it is stationary at the Upper limit switch “0” (only if this limit switch has the box or other mechanical stop and the limit switches
have been memorised in automatic or semi-automatic mode).
• This procedure adjusts
the limit
of the traction force that the motor can exert on the roller shutter in an attempt to release it, when it is stopped suddenly by an obstacle
or friction.
• There are four sensitivity levels.
• The maximum allowed sensitivity level in order to have a reliable application depends on the type, weight and dimensions of the roller shutter.
• After changing the setting, the automation must complete AT LEAST three complete cycles in order to apply the chosen sensitivity level.
