Blind/Roller Shutter Control

The Express settings can be used to move the connected drive manually to the desired position. Four group objects are available for this purpose: “Movement in manual mode” and “Stop/step in manual mode” (for roller shutters: “Stop in manual mode”). For positioning: “Height position in manual mode” and for blind only “Slat position in manual mode”.

• Move drive:
  The object “Movement in manual mode” is responsible for moving the blind or roller shutter up and down. The drive moves down if the value “1” is received and up if the value is “0”.

• Running time:
  Drive Running Time
  The activated output remains active until the set running time has expired.

• Pause on reverse for change of direction:
  Pause Time before Reverting (Pause on Reverse)
  If a control command in the opposite direction of motion is received while the drive is moving, the drive stops and waits for the defined pause on reverse time before starting to move in the new direction of motion.

• Stop drive:
  A drive that is in motion is stopped on receiving a bus telegram for the object Stop/step in manual mode (for roller shutters: “Stop in manual mode”). The value received for the object is irrelevant here.

• Slat tracking (for blind only):
  Slat Position after Movement
  Once the drive has been stopped, the slats will be rotated to the desired position according to the settings for the parameter “Slat position after movement”.

• Rotate blind slats (for blind only):
  In the case of blinds, the opening angle of the slats can be adjusted gradually using the object “Stop/step in manual mode”. For this, the drive must be at rest. If the group object receives the object value “1”, the slats are closed by one step; if the value “0” is received, they are opened.

  If a step command is executed and the slats reach one of their movement range limits or are already in a limit position, the drive will briefly move in the desired direction. The duration of this motion also corresponds to the set step time. If the direction is changed from one step command to the next, the device will once again observe the pause on reverse as the wait time between the steps.

Manually moving to the height position and slat opening angle (blind) using absolute position commands

With this function, you can set a height position for blinds / roller shutters and the slat opening angle for blinds directly and manually using a percentage value. The desired percentage value always refers to the possible movement range 0-100% that you have set by defining the running times. You thus set an absolute height position for the entire movement range.

After receiving a new positional value, the device calculates a proportional travel time from the current position and the new desired position and moves the drive in the corresponding direction of motion for the duration of this travel time. The new position is buffered again. The accuracy of the position settings depends on the accuracy of your drive running time settings.

After a number of positioning movements, there are slight deviations between the actual position and the calculated position for physical and mechanical reasons. You can reset these deviations by means of reference movements (Calibration).

If a reference movement is required before a new positioning movement, the device initiates it before the movement to the new command position (Calibration).

The group objects “Height position in manual mode” and “Slat position in manual mode” (for blind only) are available for setting the absolute positional values.

• Set height position:
  The object Height position in manual mode is responsible for the height position of the blind or roller shutter. Limit position 0% means that the blind / roller shutter is at the top. Limit position 100% means that the blind / roller shutter is at the bottom.

• Rotate slats to opening position (for blind only):
  You can use the object “Slat position in manual mode” to set the slat opening angle directly. In slat position 0%, the slats are horizontally open, or closed at the top, while 100% means they are closed at the bottom. The actual opening angle of the slats depends on the type of blind used. Setting the Blind Type (for Blind only).

When a new positional value is received, the channel calculates a running time needed to reach the new position from the current position. The drive is then moved to the new position for the calculated duration. The direction of motion is derived from the calculation.

If the device receives a new positional value during a positioning movement and the calculation results in the same direction of motion, the drive continues moving to the new command position.

• Pause on reverse for change of direction:
  If a new positioning command is received during a drive motion or slat adjustment and the calculation results in the opposite direction of motion, the drive stops and waits for the defined pause on reverse time before starting the new positioning movement.

• Slat tracking (for blind only):
  If the height position of the blind is changed and the blind reaches the desired position, the slat tracking function is executed and the slats are rotated to the desired position.

If, for example, you select the channel function Blind / roller shutter for output 1+2 on the master, an ETS channel with the name Master Output 1+2 - blind / roller shutter + name of the channel is generated. All the group objects for this channel are located here.
