Caravan Control Unit Light Status, Function - GF54.21-D-5038TSA

Model 907 

with code JA3 (Intelligent body control.) 

General 

The status request is a basic function of the MB Advanced Control control unit (N175).

The MBAC can read out statuses in the following light circuits:

IMPORTANT Pulse width modulation (PWM)

White light circuit 

The MBAC can read out the current target value for the brightness of a dimmable light source between 0 % and 100 % with an accuracy of 0.1 %. To do so, a dimmable light source must be connected to the "DO_PWM_White1_Dimmer" interface of the MBAC and be controllable.

The MBAC enables the user to set the actual target value for the brightness of a dimmable light between 0 % and 100 % with an accuracy of 0.1 %. To do so, a dimmable light source must be connected to the "DO_PWM_White1_Dimmer" interface of the MBAC and be controllable.

The MBAC can read out the current target value for the brightness of a dimmable light source between 0 % and 100 % with an accuracy of 0.1 %. To do so, a dimmable light source must be connected to the "DO_PWM_White2_Dimmer" interface of the MBAC and be controllable.

The MBAC enables the user to read out the current status of a light source (switched on or off). To do so, a pushbutton switch must be connected to the "DI_Light_Circuit_White1_Pushbutton_Switch" interface of the MBAC and the pushbutton switch must be assigned to a light source.

The MBAC enables the user to read out the current status of a light source (switched on or off). To do so, a pushbutton switch must be connected to the "DI_Light_Circuit_White2_Pushbutton_Switch" interface of the MBAC and the pushbutton switch must be assigned to a light source.

RGB light circuit 

The MBAC enables the user to read out the current target value for the intensity of the red color channel between 0 % and 100 % with a resolution of at least 0.1 %. To do so, a light source must be connected to the "DO_PWM_RGB_RGB_Red" interface and the red color channel of the light source must be controlled separately.

The MBAC enables the user to read out the current target value for the intensity of the green color channel between 0 % and 100 % with a resolution of at least 0.1 %. To do so, a light source must be connected to the "DO_PWM_RGB_RGB_Green" interface and the green color channel of the light source must be controlled separately.

The MBAC enables the user to read out the current target value for the intensity of the blue color channel between 0 % and 100 % with a resolution of at least 0.1 %. To do so, a light source must be connected to the "DO_PWM_RGB_RGB_Blue" interface and the blue color channel of the light source must be controlled separately.

The MBAC enables the user to read out the current status of a light source (switched on or off). To do so, a pushbutton switch must be connected to the "DI_Light_Circuit_RGB_Pushbutton_Switch" interface of the MBAC and the pushbutton switch must be assigned to a light source
