The solar protection actuator is used to control shutters, awnings, sunblinds or
ventilation flaps with DC 24 V.
●
End position detection by current detection for automatic move time determination.
●
Direct operation for efficient installation displaying the moving direction and active
overrides via LED.
●
Maintenance-free terminals for connecting and looping through solid, stranded and
fine-stranded conductors.
Functions for configuration with ETS:
●
Extensive control and override functions and status messages for each channel
●
On-site control of the drives
●
Direct moving to element or slat positions.
●
Automatic control of the drives with configurable behavior when the sun is shining
(sun tracking control)
●
Scene control for calling up and storing defined element positions
●
Safety functions through overrides in case of wind, rain, frost, moving blocks etc.

- Page 1 GAMMA instabus Solar protection actuator 4 x 6 A N 545D31 The solar protection actuator is used to control shutters, awnings, sunblinds or ventilation flaps with DC 24 V. ● End position detection by current detection for automatic move time determination.
- Page 2 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.
- Page 3 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.
- Page 4 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.
- Page 5 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.
