|Reset|>11 sec.|Set up the dimming level to 100%|



- ‧The factory default dimming level is at 100%. 

- ‧If the push action lasts less than 0.05 sec., it will not lead to a change for the status of the driver. 

- ‧Up to 10 drivers can perform the PUSH dimming at the same time when utilizing one common push button. 

- ‧The maximum length of the cable from the push button to the last driver is 20 meters. 

- ‧The additive push button can be connected only between the PUSH terminal, as displayed in the diagram, and AC/L (in brown or black); it will lead to short circuit if it is connected to AC/N. 

## ※ **DALI interface(primary side; for DA/DA2-Type)** 

‧Apply DALI signal between DA+ and DA- 

‧DALI protocol comprises 16 groups and 64 addresses. ‧First step is fixed at 6% of output.
