Shutter/blind functions
A shutter channel can be configured to use the shutter or the blind function. There is a specific set of parameters for each function.
The channel can be blocked from the KNX bus using the “Block” communication object. When a channel is blocked, the output stays in the last state it was before being blocked.
Measuring the travelling times
For the purpose of positioning blinds and shutters or for adjusting the opening angle of venting louvers, the actuator needs accurate information about the maximum travelling time.
Switch on the mains supply.
- If not yet done, move the blind/shutter into the upper end position (open venting louver completely).
The upper limit-stop position is reached (venting louver opened).
- Start the measuring time and move the blind/shutter by manual control into the lower end position (close the venting louver completely).
- Stop the time measurement when the lower limit (when the completely closed) position is reached.
- Enter the measured value in the ETS parameter “Duration to close”
- Repeat the same procedure from the lower limit to the upper limit position to measure the “Duration to open” parameter.
Measuring the slat moving time (only for blinds)
In the case of blinds with slats, the slat moving time is part of the overall travelling time of the blind. The slat moving time is the time required for a movement between the slat positions "closed – 100 %" and "open – 0 %". In order to compute the opening angle of the slats, the actuator needs an information about the slat moving time.
The slats must be completely closed (as in case of downward travel of the blind).
Switch on the mains supply.
- Start the measuring time and open the slats completely by manual control (as in case of upward travel of the blind).
- Take the measuring time when the completely open position is reached.
- Enter the measured value in the ETS parameter “Duration to open slats”.
Determining and configuring short-time and long-time operation
The short-time operation (Step) permits adjusting the slat tilting angle of a blind or the 'slit opening width' of a shutter. In most cases, short-time operation is activated by pressing a Venetian blind pushbutton sensor permitting manual intervention in the blind controller. When the actuator receives a short-time command while the blind, shutter, awning or louver is in motion, the travel movement is stopped immediately by the switching / blind actuator. The long-time operation (Move) is determined by the movement time of the connected Venetian blind, roller shutter/awning or louver and must therefore not be preset separately. The movement time must be measured 'manually' and entered into the ETS parameters.
To ensure that the shutter or blind has definitely reached its end position at the end of long-time operation, the actuator can extend the long-time movement by a certain percentage of the parameterized travelling time for all full upward or downward movements. In upward movement the drive motors are generally not so fast due to the weight of the curtains or to external physical influences (e.g. temperature, wind, etc.). Thus, it is ensured that the upper end position is always reached even in case of uninterrupted long time travel movements.
Calculating the slat position (only with blinds)
In the "blinds" operating mode, the switching / blind actuator always calculates the slat position so that the opening angle and thus the 'amount of light admitted' into the room by the blind can be adjusted. A new position approach by a Venetian blind will always be followed by a positioning movement of the slats. Thus, the slat positions last selected will be tracked or readjusted to a new value if a position change has taken place. In case of single-motor Venetian blind systems without a working position, the slats will be readjusted directly by a change of the Venetian blind height. For this reason, an adjustment of the slat position will always have an influence on the position of the Venetian blind itself.
Shutter
| PARAMETER | VALUES | DESCRIPTION |
|---|---|---|
| Scene control: Scene 1 Scene 2 Scene 3 Scene 4 | 0 (default) 1 to 64 | When set to 0 the channel will ignore corresponding scene. When set to another value, the channel will respond to this scene number. Channel state can be store using the scene group object for further recall. |
| Minimum ON duration Minimum OFF duration | No delay 100ms to 5 min. | Minimum duration the channel must remain in ON or OFF state before the next switching is allowed. In case of switching before the delay is elapsed, the switching action is delayed by the remaining time. |
| Reverse delay | No delay 100ms to 5 min. | Defines the pause time between two movements in reverse direction. |
| Duration to open Duration to close | 0 to 255s | Total duration for the upward (open) and downward (close) movement. |
| Number of steps | 2 to 64 | Number of steps to perform a complete movement from close to open position using a step telegram or using a pulsed dimming command. |
| Reaction on repeated command while moving | Continue moving (default) Stop | Behavior when a move up/down command is received in the same direction while it is already moving. |
| Reaction on reversed command while moving | Reverse direction (default) Stop | Behavior when a move up/down command is received in the opposite direction while it is already moving. |
| Motor startup delay | 0 to 255 (x 100ms) | Delay added to the operating duration to compensate the motor startup delay. |
| Additional time at full up/down tilting/position | 10 % (default) 0-100% | Delay added to the operating duration when arriving at the upper or lower limit to make sure the end position is fully reached. |
| Multiple speed motor | No (default) Yes | Select “Yes” when using a motor that has a low speed at startup to allow precise step/slat adjustment. |
| Slow speed ratio (%) | 50 (default) 0-100% | When multiple speed motor is selected, the slow speed ratio is the slow sleep percentage compared to the motor nominal speed. |
| Slow speed duration | 0 to 255 (x 100ms) | When multiple speed motor is selected, the slow speed duration before the motor switch to nominal speed. |
| Reaction to safety alarms | No reaction (default) Alarm 1 only Alarm 2 only Alarm 3 only On alarm 1 and alarm 2 On alarm 2 and alarm 3 On alarm 1, 2 and alarm 3 | Three general shutter/blind safety alarms can be used on the system, the reaction to the safety alarms is defined in the general settings of the system. For each channel it is possible to select if the reaction is applicable. The alarm 3 is the highest priority and its defined action will overwrite the lowest priority alarms. |
