Figure 3: Shade Tube Measurement Guide. This image illustrates how to measure the internal diameter of your shade tube, emphasizing the need for a 1-3/16 inch (30mm) compatible tube for the motor.

5.2 Circuit Installation

Follow the wiring diagram below for proper circuit installation. Ensure the power supply is disconnected before beginning any wiring work.

Figure 4: Circuit Installation Diagram. This diagram provides instructions for circuit installation, showing how to connect the motor's blue and brown wires to a 12V/24V power supply (transformer) and a switch for operation.

1. Connect the motor's blue wire to the positive (+) terminal of your 12V DC power supply.
2. Connect the motor's brown wire to the negative (-) terminal of your 12V DC power supply.
3. Integrate the motor into your existing or new shade control switch system, ensuring correct polarity for up/down movement. Refer to your switch's specific wiring instructions if applicable.
4. Ensure all connections are secure and insulated to prevent short circuits.

5.3 Motor Insertion into Shade Tube

Carefully slide the motor into the shade tube. The motor's drive adapter should fit snugly into the tube's internal profile. Ensure the motor is fully seated and secured within the tube according to your shade system's design.

6. Operating Instructions

After installation, the motor's upper and lower limits must be set to ensure the shade stops at the desired positions.

6.1 Setting the Upper Limit

Figure 5: Upper Limit Setting Procedure. This image details the process for setting the upper limit: switch on, press the UP button, use the special regulator to adjust the '+' direction by rotating the white worm, and press stop when the desired upper position is reached.

1. Ensure the motor is powered on.
2. Press the UP button on your control switch once to move the shade upwards.
3. Insert the limit setting tool into the white limit switch setting hole (marked with '+') on the motor end.
4. Rotate the white worm with the tool to adjust the upper limit. Rotate clockwise to increase the upward travel distance, and counter-clockwise to decrease it.
5. When the shade reaches your desired upper position, press the STOP button on your control switch. The upper limit is now set.

6.2 Setting the Lower Limit

Use the provided limit setting tool to adjust the lower travel limit.

Figure 6: Lower Limit Setting Procedure. This image details the process for setting the lower limit: switch on, press the DOWN button, use the special regulator to adjust the '-' direction by rotating the red worm, and press stop when the desired lower position is reached.

1. Ensure the motor is powered on.
2. Press the DOWN button on your control switch once to move the shade downwards.
3. Insert the limit setting tool into the red limit switch setting hole (marked with '-') on the motor end.
4. Rotate the red worm with the tool to adjust the lower limit. Rotate clockwise to increase the downward travel distance, and counter-clockwise to decrease it.
