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. Color temperature adj:
Step 1, PUSH turns off the lights; Step 2, press and hold PUSH to adjust the color temperature starting from the current brightness; Release PUSH, press and hold PUSH again, and adjust the color temperature in the opposite direction; No operation for 5 seconds, exit color adjustment mode.
D. Memory: PUSH dimming has a dimming memory function.
E. Dimming synchronization: The power connected to the same PUSH switch can be synchronized by pressing and holding the PUSH switch for longer than 15s
F. 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.
