The solar protection actuators are used to control shutters, roller shutters, awn-
ings, sunblinds or ventilation flap drives with up to AC 230 V.
●
End position detection by current sensing 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. Every L-conductor connection feeds two channels.
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 4/8 x 6 A N 543D31, N 543D51 The solar protection actuators are used to control shutters, roller shutters, awn- ings, sunblinds or ventilation flap drives with up to AC 230 V. ● End position detection by current sensing for automatic move time determination.
- Page 2 Characteristics The solar protection actuators are used to control shutters, roller shutters, awnings, sun- blinds or ventilation flap drives with up to AC 230 V. It is used in building automation. Device control is conducted via KNX. Through the selection of various operating modes such as manual and automatic mode, solar protection is controlled both locally and centrally.
- 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 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 For safe end position detection, the threshold value for electricity can be adjusted. The elec- tric current is evaluated in the process. 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.
