5.3.9.2 Shade (grey)

Change current device value
In the Device setup dialogue for the digitalSTROM relay terminal block shade (grey) the following parameters are available:
"Position"The setting of the device value is interpreted by the digitalSTROM relay terminal block as position. For this purpose, the digitalSTROM relay terminal block must be calibrated appropriately after installation (see chapter
5.3.6).
Use Stop to stop the motion of a shading system e.g. if Open or Close was previously used to travel to the end position.
With Open, the movement command to fully open the shutters or extend the awning can be started.
With Close, the movement command to fully close the shutters or retract the awning can be started.
"Set blade angle"The blade angle can be set by direct text input (values between 0-100 %) or with a slider. The blade angle must be calibrated appropriately after installation. (see chapter
5.3.7).
Editing device properties
In the Edit devices dialogue the following parameters are available to you:
"Push button"You can selected between device push button, area push button, room push button or group push button (refer to Chapter
5.3.9.1).
Fig. 39: Editing device properties blinds dialogue
"Orientation"
Here, you can select the wall orientation of your shading system, e.g. South.
"Wind protection class"
Here, you can select the wind protection class (1 to 6) according to EN 13561+A1 (Tab. 1 and Tab. 2) for your shading system. A new group is created automatically for this blind of the south wall, e.g. south - class 1 – 9.0 m/s.
The orientation and wind protection classes are used mostly in the building automation application where different shading systems are to be controlled by several wind monitors or weather stations.
Please note that blinds, shutters and awnings are subject to specific guidelines for wind protection classes (e.g. EN 13561+A1 Tab. 1 and Tab. 2). You can find this information in the product description of your shading system.
Tab. 1 Wind protection classes for shutters, venetian blinds and folding shutters (according to SN EN 13659+A1)
Wind class | 1 | 2 | 3 | 4 | 5 | 6 |
Wind speed gusts (m/s) | 9.0 | 10.7 | 12.8 | 16.7 | 21.0 | 25.6 |
Nominal test pressure (N/m2) | 50 | 70 | 100 | 170 | 270 | 400 |
Tab. 2 Wind protection classes for awnings (according to SN EN 13659+A1)
Wind class | 0 | 1 | 2 | 3 |
Wind speed gusts (m/s) | <7.8 | 7.8 | 10.6 | 13.3 |
Edit Shade Device Properties Allows adjustment of the properties of digitalSTROM relay terminal blocks used for the control of motorised shutters, blinds or awnings.
The values for
Motion time open-close and
Motion time close-open as well as the
Direction of travel are detected during the calibration. (see chapter
5.3.6).
In the Shade device properties dialogue the following parameters are available:
"Motion time open-close"
Time the shading system needs to travel from the opened/extended end position to the closed/retracted end position.
"Motion time close-open"
Time the shading system needs to travel from the closed/retracted end position to the opened/extended end position.
"Turn blades"
Time a blind needs to open or close its blades.
Only active for blinds.
"Direction of travel"
Determines the direction of travel of the connected motor. The direction of travel for the motion commands Open/Close can be reversed depending on the shading system or manufacturer.
"Default"
Default direction of travel open/close
"Reverse"
Reversed direction of travel close/open
"Protect calibration values"
Protects parameters against being overwritten by the calibration. Calibration can only be initiated in the web-based digitalSTROM Configurator or via inching commands if the protection is lifted. This setting prevents the unintentional overwriting of calibration data during the setup of new presets.
"Calibrate motion time and direction"Determines the motion time and direction of travel for the shading system connected to the digitalSTROM relay terminal block. For more information on this subject, refer to Chapter
5.3.6.
„"Calibrate Turn Time"Determines the turn time for the blades of the blinds connected to the digitalSTROM relay terminal block (see chapter
5.3.7).
Comment on the handling and interpretation of properties for different shading systems:
Shading system | Motion commands/Position in Off preset |
Shutters | Usually operated via 2-way push button. Motion time open-close: Motion time to lower shutter Motion time close-open: Motion time to raise shutter Shutters are used as screens or as weather and burglar protection. In the factory settings of the digitalSTROM relay terminal block Shutters (grey) the shutters are closed (shut) in the Off preset. |
Blinds | Usually operated via 2-way push button. Motion time open-close: Motion time to lower blind Motion time close-open: Motion time to raise blind Blinds are used as screens or as weather and sometimes as burglar protection. In addition to their position, you can also control the angle of the blades. Blinds are also known as slat blinds. In the factory settings of the digitalSTROM relay terminal block Blinds (grey) the blinds are closed (shut) in the Off preset. |
Awning | Usually operated via 1-way push button. Motion time open-close: Motion time to retract awning Motion time close-open: Motion time to extend blinds Typically awnings are shading systems made of fabric. For this reason they are usually retracted during bad weather or absence. In the factory settings of the digitalSTROM relay terminal block Awning (grey) the awnings are retracted in the Off preset. |
In the Advanced settings tab the following parameters are available:
"Motion time when blinking"
Blinking is indicated by a short motion of the shading system.
Motion time for the blinking motion.
"Maximum motion time"
Specifies the maximum motion time in one direction. The motor stops after this time (120 seconds by default). If a large shading system that needs a longer motion time is connected, this time can then be increased manually here.
"Reverse time on direction change"
Duration of the motion break caused by a direct reversal of direction.
"Follow-up time at end position"
Maximum period of time after the end of the motion time while the motor is still supplied with power by the digitalSTROM relay terminal block. This ensures that the end position is reached in case of increased motion time (e.g. caused by cold weather or dirty guide rails).
"Threshold of end switch recognition"
The digitalSTROM relay terminal block monitors the load current. If the load current drops below this threshold the reaching of the end position is detected. It drops once the shading system runs up on the integrated limit switch.
During standard operation the threshold must not be set to less than 116 mA (in factory settings the threshold is 232 mA). If the value is set to less than 58 mA, limit switch recognition is deactivated and the digitalSTROM relay terminal block switches off the load after the defined motion time.
"Number of steps for fine tuning adjustment"
Number of motion steps for fine tuning adjustment (Open/Close push button pressed for long) before continuous travel is started. Set the value at 0 if continuous travel is meant to start directly.
"Motion time for fine tuning adjustment"
Duration of motion steps for fine tuning adjustment. Used to determine the distance (or angle for slat blinds) of individual motions for fine tuning adjustment.
Information for digitalSTROM devices with push button inputs in groups
If a digitalSTROM push button block is allocated to a group, the name of the group is automatically allocated in the properties dialogue and displayed with the group name and the addition (Group).
Fig. 40: Device properties dialogue of a digitalSTROM shade push button block (grey)
If a digitalSTROM device with a push button input is assigned to a group (e.g. digitalSTROM shade push button block (grey), the group will also be available in the properties dialogue but will not be automatically assigned. This makes it possible for the push button connected to the digitalSTROM device to be used as a central button for the group as necessary.
