Installation

1. Power off
   • WARNING Please install and maintain the device by a professional electrician. To avoid electric shock hazards, do not operate any connection or contact the terminal connector while the device is powered on!
2. Wiring instructions
   • To ensure the safety of your electrical installation, it’s essential that either a Miniature Circuit Breaker (MCB) or a Residual Current operated Circuit-breaker with Integral Overcurrent protection(RCBO) with an electrical rating of 1A has been installed before the MINI-RBS.
   • Momentary Switch Wiring:
   • Three-Position Rocker Switch Wiring:
   • *Make sure all wires are connected correctly.

3. Power on
   • When the device is used for the first time, it will enter pairing mode by default after being powered on. At this time, the LED indicator will flash in a pattern of “two short and one long”.
   • *The device will exit the Pairing Mode if not paired within 10mins. If you want to enter this mode, please long-press button for about 5s until the LED indicator changes in a cycle of two short and one long flash and release.
   • *As the maximum one-way allowable continuous operation time for the motor in this device is 2mins, please pause the operation before the curtain reaches its limit position to avoid damaging the motor.

Check the Device Status

1. External switch type
   1. The types of external switches supported are three-position rocker switches and momentary switches, with the default setting from the factory being the rocker switch (Edge Mode).
   2. The method to switch the external switch type: Short-press the button three times and the blue light flashes 3 times, then the switch type is switched successfully.
   3. External switch trigger mode switching sequence (cycle): Edge Mode → Pulse Mode → Following Mode
2. Roller shutter direction test
   • Press the external switch to check if the roller shutter moves in the correct direction. If it does not, power off the device, swap the Lout1 and Lout2 wires, and test again.
