6. Installation Guide

Before starting, ensure power is disconnected at the circuit breaker. It is recommended that installation be performed by a qualified electrician.

6.1 Wiring Instructions

Use 14 AWG electrical wire for connections. The sensor has clearly marked terminals for Line (IN) and Load (OUT) connections, including Neutral (N) and Live (L) for both input and output.

Figure 5: Wiring diagram for the YCA1050 sensor, showing connections for Neutral (N) and Live (L) for both input power and the connected load. Note the small terminal screws requiring a tiny Philips screwdriver.

Identify the incoming power wires (Line IN) and the wires going to your light fixture or load (Load OUT).
Connect the Neutral (N) wire from the incoming power to the 'N ~IN' terminal on the sensor.
Connect the Live (L) wire from the incoming power to the 'L ~IN' terminal on the sensor.
Connect the Neutral (N) wire going to your load to the 'N Load' terminal on the sensor.
Connect the Live (L) wire going to your load to the 'L Load' terminal on the sensor.
Ensure all connections are tight and secure.

Note: The sensor does not include a ground connection. Ensure proper grounding is maintained within your electrical box or system as per local codes.

6.2 Mounting Options

The YCA1050 sensor can be mounted in two primary ways:

6.2.1 Flush Mount on Ceiling Electrical Box

Connect wires to the sensor unit as per the wiring diagram (Figure 5).
Secure the sensor onto the ceiling electrical box using the two included screws. The screw hole distance on the sensor is approximately 2.75 inches, designed to align with standard electrical boxes.

6.2.2 Direct Mount onto Drywall Ceiling

Before mounting, drill appropriate holes into the drywall ceiling.
Insert the provided plastic sleeves into the drilled holes.
Exercise caution to avoid puncturing any wires inside the ceiling during drilling.
Connect wires to the sensor before securing the sensor to the ceiling with the screws into the plastic sleeves.

6.3 Optimal Placement

For optimal performance, install the sensor approximately 6 feet away from your light fixture to prevent the photocell from being affected by the light it controls.
Avoid installing near heat sources (e.g., vents, radiators) or in direct sunlight, as this can cause false triggers.
Ensure the sensor has a clear line of sight to the area where motion is to be detected.

7. Operation and Settings

After installation, restore power to the circuit. The sensor will enter a warm-up period (typically 30-60 seconds) during which it may cycle on and off. Once warm-up is complete, the sensor is ready for adjustment.

7.1 Adjusting Time Delay (TIME)

The "TIME" dial controls how long the connected light or device remains on after motion is no longer detected. Use a small Philips screwdriver to adjust this dial.

Rotate clockwise to increase the delay time.
Rotate counter-clockwise to decrease the delay time.
Available settings range from approximately 5 seconds to 8 minutes.

7.2 Adjusting Ambient Light Sensitivity (LUX)

The "LUX" dial controls the ambient light level at which the sensor will activate the connected device. This feature ensures the light only turns on when needed, saving energy. Use a small Philips screwdriver to adjust this dial.

Rotate towards the "Sun" icon (higher LUX value) for the sensor to activate in brighter conditions (e.g., during the day).
Rotate towards the "Moon" icon (lower LUX value) for the sensor to activate only in darker conditions (e.g., at night or in very dim areas).
Available settings range from approximately 5 Lux (dark) to 2000 Lux (bright).

Tip: To test the motion detection regardless of ambient light, set the LUX dial to the maximum (Sun icon). Once motion detection is confirmed, adjust the LUX dial to your desired ambient light level.

8. Maintenance

The J.LUMI YCA1050 PIR Motion Sensor requires minimal maintenance.

Cleaning: Periodically wipe the sensor lens with a soft, dry cloth to remove dust or debris that may obstruct detection. Do not use abrasive cleaners or solvents.
Inspection: Occasionally inspect the sensor for any visible damage or loose connections. If any issues are found, disconnect power and consult a qualified electrician.

9. Troubleshooting

If you experience issues with your J.LUMI YCA1050 PIR Motion Sensor, refer to the following common problems and solutions:

Problem	Possible Cause	Solution
Light does not turn on when motion is detected.	No power to the sensor. Incorrect wiring. LUX setting is too high (sensor thinks it's bright enough). Motion is outside detection range or angle. Faulty bulb/fixture.	Check circuit breaker. Verify wiring connections (refer to Figure 5). Ensure Line IN and Load OUT are correctly connected. Adjust LUX dial towards the "Moon" icon. Reposition sensor or ensure clear path for detection. Test light fixture with a standard switch or known good bulb.
Light stays on constantly or turns on without motion.	TIME setting is too long. Sensor is detecting constant motion (e.g., fan, pet, swaying curtains). Sensor is affected by heat sources (HVAC vents, direct sunlight). Sensor is too close to the light fixture (photocell interference).	Adjust TIME dial to a shorter duration. Identify and remove sources of false triggers. Relocate sensor away from heat sources. Ensure sensor is at least 6 feet from the light fixture (refer to Figure 7).
Detection range is poor or inconsistent.	Obstructions blocking sensor's view. Installation height is too low or too high. Ambient temperature is too close to body temperature.	Clear any objects obstructing the sensor's field of view. Ensure installation is within the recommended 5-12 feet height. PIR sensors are less effective when ambient temperature is similar to body temperature. This is normal operation.
