The blinds can be raised or lowered, or the movement can be stopped
using the relative command. When a blind stops, the actuator receives a
short movement command and the laths are rotated.
If the Stop command is not sent, the motor will only stop at the end of
the Movement Time: the blinds must therefore be fitted with stroke end
sensors or an autonomous clutch.
Alarms control
If this function is enabled, the actuator completely opens or closes the
shutters (blind, motorised curtain) when it receives an alarm message from
a wind or rain sensor.
The open or close option is set during the programming phase.
As an extra safety measure, if the actuator does not receive a "no alarm"
message for more than 30 minutes from the sensor, it interprets this as
a malfunction and consequently moves the shutter to the preset safety
position.
The alarm status persists until the actuator receives a "no alarm" message.
At the end of the alarm status, the actuator returns the shutter to its
original position (or performs the last command received, if it received
a command during the alarm status phase).
Performing priority controls
On receiving an override command, it moves the shutter to the set position
(UP or DOWN). Until the priority control is cancelled, the actuator will ignore
all other commands it receives, including wind or rain alarms.
When the priority control is cancelled, the actuator returns the shutter to
its original position (or performs the last command received, if it received
a command during the priority status phase).
Scene Management
Each actuator channel is able to memorize and perform up to 8 scenes;
each one is associated to a precise position (UP, DOWN or intermediate)
of the shutter.
The scene can only be learned when the shutter is at a standstill.
Move the shutter to the desired position before memorising the scene.
