The module is used to control and position slat blinds with 230V AC motors and can operate in 3 basic operating modes:
The module has 4 relay outputs (0.05 - 2A) for direct connection of the 2 blind motors. The module automatically determines the calibrated running time of the motors during each run. The slat adjustment is processor-controlled with a computer accuracy of 256 steps for the setting of 0-180°.
Programming and configuration of the blind module is very easy with our programming software ProgramDesigner (from ProgramDesigner version 4.10, Master version V4.76; Compiler V4.75). The specific parameters of the individual blinds are transferred to the blind module via the Master Module. The current signalling of the relay states for controlling both blind motors takes place via LEDs.

The Blind Control Module JSM-02C-230V-2A operates in 4 operating modes (mode 1-4), which are set by the outputs Ax.7 and Ax.8 of the Master Module.
Notice: The specifications "Register" and "Parameter" in the following text always refer to the ISYGLT Programming Software ProgramDesigner.
|Operating mode||Function||State Ax.7||State Ax.8|
|Mode 1||Manual operation||0||0|
|Mode 2||Automatic operation||1||0|
|Mode 3||Set point operation||0||1|
|Mode 4||I/O operation||1||1|
This mode is used for manual driving of the blinds. The following functions are possible:
In this mode, the blind is moved fully automatically and the slat angle is adjusted. The following functions are possible:
Table of conditions 1: All conditions in the table are AND functions.
|1||The azimuth (direction from which the sun shines) must lie between the left and right edges of the window.||Azimut Begrenzung links|
Azimut Begrenzung rechts
|2||The elevation (elevation angle of the sun above the horizon) must lie between the lower and upper viewing angle limits of the window.||Elevation Begrenzung unten|
Elevation Begrenzung oben
|3||The wind protection must not be active.||Wetterschutz|
|4||The preset shading light intensity must be reached.||The calculation of the shading light intensity is described later.||Beschattung|
Table of conditions 2: All conditions in the table are AND functions.
|1||The wind protection must not be active.||Wetterschutz|
|2||One of the two forced shading light intensities must be reached.||Beschattung|
Slat angle calculation if the conditions in Table 1 are fulfilled
For the calculation there is a parameter table, which contains the slat angles in dependence on the elevation (elevation angle of the sun over the horizon).
The resolution of this table is 10°, related to the elevation. Thus for all elevation values from 0 to 90°, at a distance of 10°, a corresponding slat value can be stored. If the sun is between the elevation values graded in 10°, the slat angle is interpolated. Thus, different driving strategies can be realized depending on the elevation. By default, the table values are set so that the slats are always at 90° to the sun, i.e. provide the greatest possible glare protection. If the blind is to allow some sunlight through even when the sun is shining, the following values (register "Blendschutz") have proved their worth:
|Elevation 0 grd||15 grd|
|Elevation 10 grd||25 grd|
|Elevation 20 grd||35 grd|
|Elevation 30 grd||45 grd|
|Elevation 40 grd||55 grd|
|Elevation 50 grd||65 grd|
|Elevation 60 grd||75 grd|
|Elevation 70 grd||85 grd|
|Elevation 80 grd||90 grd|
|Elevation 90 grd||90 grd|
To include indirect glare, e.g. from opposite window surfaces, in the shading or glare protection, there are still 5 glare areas available in the register "Blendschutz".
|Art Steuerung Lamelle||Direkt Elevation (or fixed angle)|
|Azimut Begrenzung links||e.g. 90 grd|
|Azimut Begrenzung rechts||e.g. 35 grd|
|Elevation Begrenzung unten||e.g. 1 grd|
|Elevation Begrenzung oben||e.g. 90 grd|
To implement daylight control systems, the correct slat angle for the respective elevation angle must be specified by the manufacturer of the blind or determined by testing (e.g. in manual operation).
Slat angle calculation if the conditions in Table 2 are fulfilled
The slat angle assigned to the respective forced shading light intensity is approached. The activation of forced shading is reported back to the BMS system.
Calculating the shading light intensity
The currently measured brightness value of the light sensor from the set evaluation direction is used for calculation. To avoid swinging, the delay time for shading and unshading can be set separately. The measured outdoor light value is smoothed by a time filter. The outdoor light value can also be changed by the BMS system. The scaling of the outdoor light value is enabled in the register "Allgemein". This option is intended for special applications. For standard applications, this parameter should be set to "nicht verwenden".
|Ansprechzeit (Verzögerungszeit) (Sekunden) Verschatten||Allgemein|
|Ansprechzeit (Verzögerungszeit) (Sekunden) Entschatten||Allgemein|
The limit value of the shading light intensity depends on the current elevation. If the elevation is less than 0°, the shading light intensity is automatically considered not to have been reached.
The light threshold value is determined from the following 4 elevation limit values:
|Parameters to be used||Value||Register|
|Elevation 0 bis 9 grd||3 klx||Blendschutz|
|Elevation 10 bis 29 grd||10 klx||Blendschutz|
|Elevation 30 bis 59 grd||30 klx||Blendschutz|
|Elevation 60 bis 90 grd||40 klx||Blendschutz|
Special functions in "Automatic operation"
In "Automatic operation", the blind can be moved to a predefined slat angle if one of the above conditions is not met. The blind can thus be lowered generally during the day, for example, even if the outside light is lower than the specified threshold value.
If the outdoor light value defined in the parameter is not reached and after the specified time has elapsed, the blind can, when enabled (parameter), assume an angle defined by parameter (see register "Allgemein").
In this mode the blind slat angle is adjusted by the Master. This is required if, for example, cleaning positions or separately programmable controls are to be implemented in which the slats are to be set to defined angles.
In this mode the module works like a normal switching module.
In general, each blind module works independently. During commissioning, the parameters determine where the blind is located and which positions of the sun are to be expected. The module determines its driving strategies from the weather data supplied via the BUS. If several modules are in operation on one side of the facade, they may work with a slight delay. To prevent this, a module can be used for synchronisation.
