8. ON/OFF & Description of Dimming Operation
A. Short-press the PUSH switch (short-press time 0.1s-1s), the LED driver will turn on or off.
B. Dimming: Press and hold the PUSH switch (1s-8s), the LED driver can achieve dimming, brightening, or dimming, the dimming range is 2-100%.
C. Memory: PUSH dimming has a dimming memory function.
D. Dimming synchronization: The power connected to the same PUSH switch can be synchronized by pressing and holding the PUSH switch for longer than 15 seconds.
E. DALI dimming mode: Connect the power supply to the DALI system, and it can be dimmed by the DALI host. The dimming range is 0-100%.
9. Matters needing Attention
1) The LED string must be connected to the load before turning on the input power; otherwise, the LED string may be damaged.
2) After the LED drive input is powered off, there will be a residual voltage at the output, which can be maintained for about 3 minutes.
3) Before setting the parameters by NFC, please make sure the driver is powered off.
