5.3.7 Turn time calibration for the digitalSTROM relay terminal block Shade
Blinds are mechanically constructed to close the blades when they are lowered.
If the blinds are re-opened, the blades are first turned over before the entire blind is raised. Due to this mechanical peculiarity the blades of many blinds can be controlled.
The digitalSTROM relay terminal block grey (Shade) can move the blades into the desired position. Here, the blade angle is not directly controlled by the terminal block power output. Instead, it is calculated on the basis of the turn time (running time of the motor needed to open/close the blades).
Therefore, after connecting a shading system with blades, the turn time must be calibrated. During calibration, the times for the complete opening and closing of the blades will be determined.
It is imperative for the parameters to be determined in order to ensure safe and faultless operation.
Calibration by digitalSTROM Configurator
To perform the calibration in the digitalSTROM Configurator, in the
Hardware main section use the command
Edit shade device properties (
Fig. 33).
Edit shade device properties.Fig. 33 Shade device properties dialogue
Start calibrate turn time to determine the turn time of the blades manually.
This calibration takes 2 steps. In the first step, the turn time is roughly measured (
Fig. 34) and in the second step the complete opening and closure is checked visually and changed if necessary (
Fig. 35). Confirm the settings in each case with
Next and
Finish.
Calibration - step 1 of 2:
Fig. 34 Calibration turn time dialogue: Rough adjustment - Step 1
Calibration - step 2 of 2:
Fig. 35 Calibration turn time dialogue: Fine adjustment - Step 2
You can always use Reset to return the turn time to the factory settings of 3 seconds.
To allow full visual concentration on the blade angle, you can open or close the blades by using the arrow keys and on your computer keyboard. Use the arrow keys and to approach the middle position.
Calibration using digitalSTROM push button (without dSS)
The turn time can only be calibrated by using the web-based digitalSTROM Configurator.
