Precautions for use
1. If the negative pole of the auxiliary power supply of the driver and the negative pole of the dimming interface are separated, they need to be short circuited and connected to the controller # 2.
2. If the controller is installed very close to the light source surface of the lamp, after the induction lighting duration is over, the micro brightness may light itself out.
3. Because the zhaga controller has no ability to cut off the AC power supply of the driver, the customer needs to select a driver whose output current can be close to 0 MA when using the zhaga controller, otherwise the lamp may not be completely turned off. As can be seen from the output current curve in the driver specification, the minimum output current is close to 0 MA.
4. The controller only outputs the dimming signal to the driver, regardless of the power load of the driver and the light source.
5. During the test, do not use your fingers to block the photosensitive window, because the gaps between your fingers may transmit light and cause the failure of turning on the light.
