Switching/Blind Actuator

1 Functional Characteristic

The switching/blind actuator is a freely configurable relay unit. The basic usage areas are on/off
switching for lightning systems and blind/shutter mechanisms (awnings, blinds, shutters and
various sun and visibility protection devices) used in homes, theaters and all other buildings. The
module can be configurable per one channel according to usage mechanism. One channel can be
configured for on/off or blind/shutter mechanism. The module have the switching capacity of 16A
with high-inrush current capability.
Each channel of these switching actuators has a LED which indicates its switching status and a
manual switch with the settings ON/OFF for switch actuator and UP/DOWN for blind actuators.
A mains connection is required for operation of the manual switches, but the bus voltage does not
need to be present.
Features which can be adjusted via parameter settings including the basic functions of
"Switching", "On/Off Delay", "Pulse", "Staircase" for switching actuator and "Blind", "Shutter"
for blind actuator. In addition, the following can be parameterized for each channel: Input logic,
type of contact (NC/NO) and participation in central commands such as continuous ON,
continuous OFF, central switching and access/recall scene for switching actuators and central
up/down for blind/shutter actuators. 3 safety objects (Safety1, Safety2 and Safety3) can be used to
drive sun and visibility protection devices to a defined position (e.g. during a storm or when it is
raining).
Features of the switching actuators
 Manual control for each channel.
 Status LED for each channel.
 High switching capacity (16A with high-inrush current capacity).

4 different channel functions can be selected:
- Switching
- ON/OFF Delay
- Pulse function
- Staircase light timer with switch-off pre-warning.
 Possible integration of the channels into a maximum of 8 scenes.
 Adjustable response to bus failure and restoration of the bus/mains power.
 Logical functions.
