Siemens UP 520/31 Technical Product Information

Blind actuator UP 520/31
Product and Function Description
The blind actuator receives telegrams from sensors via the
Instabus and controls a shutter or blind motor with its
output. Both travel directions are mechanically
interlocked. With sun protection or positioning telegrams,
the actuator offers moreover the possibility of moving
shutters, blinds and slats into any desired position. On
reception of a storm warning, the actuator is capable of
moving shutters or blinds into a predefined safety position
and to lock them up in this position.
In addition, the device has two extension inputs that
depending on parameter settings, can act directly on the
output (local operation, see "state of delivery") or
alternatively also as binary inputs on the Instabus. The
connected potential-free switch or push button contacts
are read in via a common reference potential on the
actuator. As binary input, telegrams can be transmitted for
switching or dimming, for Venetian blind control, value
setting or scene recall / save.
State of delivery:
• When delivered, the switching state of the outputs is
undefined.
• On application of the bus voltage, the relays will switch
off.
• With the bus voltage applied, the extension inputs
control the relays of the actuator as follows:
