DC 24 V FELV is supplied centrally via separate connection terminals to control the motor drives. Solar protection actuator N 545D31 consists of the device (hardware) and the application program (software). Depending on its use, each relay output channel can be assigned differ- ent functions.

Resetting the device to factory settings A very long push of the programming button of more than 20 seconds resets the device to its factory settings. This is indicated by the programming LED flashing steadily for 8 seconds. All configuration settings are deleted. The building site function of the delivery state is re-ac- tivated.

Scene control 8-bit scene control Using 8-bit scene control, current solar protection or slat positions can be assigned to a scene and retrieved. Move to position 1/2, 3/4 (1-bit scene control) The function “move to position 1/2, 3/4” is particularly suitable to repeatedly move to pre- ferred element positions in combination with the 1-bit scene control.

The drives can be controlled with start-up delays or run on for a configured time. Status messages Responses on element positions, such as dynamic element position, slat position, moves, moving directions, reaching the upper or lower end position are reported. In addition, re- sponses to the different overrides, current operating mode such as direct operation or auto- matic operation can be displayed.
