The combo actuator has three different types of
alarms available; wind, rain and frost.
The wind alarm can be used to protect shutters and
buildings from strong wind while the rain alarm to
protect the windows. On the other hand, the frost
alarm can be used as a protection against
mechanical damage with low temperatures.
There are three different communication objects,
one for each type of alarm, which shows the status
of the alarms. The value 0 indicates no alarm while
the value 1 means that an alarm has occurred.
The reaction of the shutter when one alarm occurs
and at the end of it can be configured via the
window parameters. The shutter can remain the
last state, can be lowered, raised or positioned at a
predetermined value.
Normally these functions are used together with a
weather station which allows knowing the wind
speed, the temperature and the existence of rain.
SCENES
Up to 16 scenes can be configured for each
shutter/blind output. The configuration of each
scene permits:
- Assign a number of scenes (1-64).
- Set a position indication for the shutter.
- Set a slat angle value for the blind.
- Enable storing of the scene.
- Define an ON Delay for the scene.
Via the object “scene”, telegrams which contents
the call or store functions of a scene are sent.
Up to 64 different scenes are managed via a single
group address and the scene number telegram
must match with the scene number previously
configured in the combo parameters. The scene
number (1-64), is used to recall the scene via the
corresponding object. For storage the scene, the
value sent via the object “scene” must be
128+scene number.
When a scene is configured with a
number, the value to send for calling
that scene must be that number -1. For
example, if a scene is configured with
the number 24, the number to be sent
via the object “scene” must be 23. On
the other hand, the value 152 (128+23)
must be sent for storage the scene
number 24.
The recall of each scene can be delayed whether a
time delay has been defined previously in the
parameter window. This option allows creating
dynamical scene sequences when several outputs
are combined with different delays.
After ETS programming, the scene
values parameterized for the output
concerned will be overwritten into the
actuator. It means that any change made
by the user will be deleted. Therefore it
is important, before any maintenance, to
know the previous scene configuration
and whether the user wants to keep
operating with that configuration.
FEEDBACK FEATURE
The current status of the shutter can be shown via
different objects. For the shutter position the object
used is “Position Indication in %” while for the slat
position it is “Slat Angle Indication in °”.
Additionally, there is another object, “moving
stat
us”, which indicates whether the shutter is
moving or no. When the shutter is moving, this
object takes the value 1 whereas when it is stopped
the value is 0.
When the feedback telegram is enabled, the status
information is transmitted every time that a change
occurs on the outputs. However, it is also possible
to define a periodical sending of the status through
the parameter “Feedback Periodical Sending”.
Thereby, the current value of the above objects are
transmitted with the period configured.
Additionally, to reduce the bus traffic after any
failure, a delay for the status feedback transmission
at startup can be parameterized. When this option
is used, the status of the shutter after a bus voltage
failure is sent once the time delay configured has
elapsed.
The delay configured only affects the
sending of the feedback. The behaviour of
the shutter has no effect and it can even
be modified during the course of the delay.
BUS VOLTAGE FAILURE
Only the behaviour of the shutter after bus voltage
failure can be parameterized. The combo actuator
allows three different behaviours for bus voltage
failure:
