Dimming actuator, 4-gang CAUTION! Danger of destruction. 400 V are shorted when outputs switched in parallel are con- nected to different outer phase conductors. The device will be destroyed. Always connect outputs switched in parallel to the same outer phase conductor. Delivery state: The outputs can be operated with manual control.
Wait about 15 s. ■ Press and hold down the programming button. ■ Switch on the bus voltage or attach the KNX device connection terminal. Re- lease the programming button only after the programming LED starts flashing slowly. The safe-state mode is activated.
Restoring the factory settings causes the devices to lose their physical address and configuration. Technical data KNX medium TP256 KNX commissioning mode S-mode Rated voltage KNX DC 21 ... 32 V SELV Current consumption KNX 6 ... 15 mA...

Dimming actuator, 4-gang For LV-LED: Check the lamp operating device and replace as necessary. With the "Universal" setting: Define the dimming principle manually. Connected HV-LED lamps or compact fluorescent lamps in the lowest dimming position are too bright; dimming range is too small Cause 1: The set minimum brightness is too high.

Dimming actuator, 4-gang When a short-circuit occurs during the calibration process, the load calibrates itself again after the short-circuit is eliminated. Cause 4: load failure. Check load, replace lamp. For inductive transformers, check primary fuse and replace if necessary. Manual control with button field not possible Cause 1: Manual control has not been programmed.
