Product ID

BM92D3021-1

The product is a roller shutter controller module for AC motors, equipped with obstacle detection functionality. During the operation of the roller shutter, the product detects changes in the motor's voltage and current parameters to determine if an obstacle is encountered and controls the motor's actions to prevent accidents.
Additionally, the product features the environment adaption function and will automatically adjust the obstacle detection threshold based on long-term usage conditions.

DESCRIPTION

It is necessary to calibrate the upper and lower thresholds via Environment Learning Mode when installing a new roller shutter.

Upper threshold: controls the roller shutter to operate from the bottommost position to the topmost position.
Lower threshold: controls the roller shutter to operate from the topmost position to the bottommost position.

⬥ Refers to the “Environment Learning” paragraph in the datasheet for more information.

There is no specific order for the upper and lower threshold calibration.
Please ensure there are no obstacles during the calibration process.
It is recommended to cool down the motor before calibration.

PIN DESCRIPTION

Pin	Pin name	Function
1	VP	OPA non-inverting input: connects to the live wire (monitors the motor's operating voltage)
2	VCC	Power supply: 10V~20V (non-isolated side)
3	GND	Ground: shares a common ground with the neutral wire (non-isolated side)
4	IP	OPA non-inverting input (monitors the motor's operating current)
5	IN	OPA inverting input (monitors the motor's operating current)
6	VDD	Power supply from the master: 3V~5.5V (isolated side)
7	RX	UART: RX
8	TX	UART: TX
9	VSS	Ground: shares a common ground with the master (isolated side)
