Fig14. Position Indication %
Example:
The measurement time results the following
values:
Up Movement Duration (sec): 110
Down Movement Duration (sec): 105
The shutter is at 0% and a new telegram command
is received to be positioned at 40%. The combo
calculates the time necessary to achieve the
desired position taking the duration configuration
into account: 105 sec x 0.40 = 42 sec. Then the
output responsible of lowering the shutter will be
activated for 42 seconds and the current position
will be 40%. If at that moment a new telegram of
positioning is received with the value 20%, the
combo will make the following calculations: 40-20=
20%. This is the difference between the two
positions and therefore the motion time will be: 110
sec x 0.20 = 22 sec. This time the output
responsible of raising the shutter will be activated
for 22 seconds and the current position will be 20%.
SLAT ANGLE INDICATION
°
The combo actuator can also calculate the current
position of the slats when the function selected is
shutter/blind. This is calculated according to the
parameterization of “Slat Angle Step Count for
0...180°”. This parameter determines the number
of steps required to move the slats from the 0
°
position to the 180° position. The time of these
steps is configured through the parameter
“Duration of Short Movement”. For the correct
operation of this option, it is imperative that the
calculation of these steps is done correctly in order
to achieve the best possible positioning results.
(See the Appendix D: Measurings)
Fig15. Slat Angle Indication°
The real angle position of the slat is from
0
° to 180° but the indication of this
position via the object
“Slat Angle
Indication in
°” is shown as 0-360°. The
value 360
° corresponds to the position
180°. Likewise, when a new value for a
position of the slat is sent, the possible
values are between 0
° and 360°.
LOCKING
This function allows the shutter to be locked to a
position. During a locking, the outputs are blocked
and they can no longer be controlled via any
telegram.
It is possible to define the value during the locking
and the value that the shutter takes after the
locking.
When the parameter “Output Status at
End of Locking” is set to “No Reaction”, the shutter
will not move at the end of locking and therefore it
will remain the last position.
The locking function remains active
even after a bus voltage failure.
The manual control via the push buttons
of the device is possible during the
locking.
