When using the shutter/blind pushbutton (5TA2 114), the
shutter/blind can be manually moved to the required position
(UP/DOWN or STEP command). The number of connectable
conventional extension units is unlimited.

I2_08612a
Together with the UP 211 wave shutter/blind pushbutton inserts,
the sys shutter/blind control insert $ is implemented as a central
operating point. The inserts % and & individually control the
respective shutter/blind motors M (( and )). The time values
stored in the UP 211 wave shutter/blind pushbutton
(e.g. 8:00 UP and 20:00 DOWN command) allow the timecontrolled
stopping and starting of all connected motors.
Caution:
• It is not permissible to use a shutter/blind control sys insert as
the central operating point and directly operate a shutter/blind
motor.
• When protecting the central operating point against short circuit
using a separate residual current operated circuit breaker,
both circuits must be isolated in order to prevent inadvertent
tripping of the circuit breaker.
Example 3:
Integrating a wind alarm
The indicator for the wind alarm is integrated in the shutter/blind
control over the extension unit input. In the event of a wind alarm,
the shutters/blinds are raised and locked in that position until the
wind alarm is reset over the indicator. As long as the interlock is
enabled, neither manual nor automatic operation of the shutters/
blinds is possible.
