Wiring Diagram and Connections
Begin by identifying the power source and ensuring the circuit is de‑energized before any work. Remove the existing switch plate, then use a voltage tester to confirm no voltage at the line terminals. The MS‑OPS5M has three primary terminals: L (line), N (neutral), and G (ground). Wire the incoming line to the L terminal, ensuring a snug fit and tightening the screw to secure the connection. Connect the neutral wire to the N terminal, matching the wire color to the device’s neutral marking. The ground wire should be attached to the G terminal; use a green or bare copper wire for safety compliance. After all connections are secure, replace the switch plate and restore power to the circuit. Use a multimeter to verify continuity between L and G, and between N and G, before testing the switch operation. If the switch fails to activate, double‑check that the line voltage matches the device’s rated voltage and that no wires are loose. For advanced troubleshooting, consult the Lutron support portal or contact technical assistance for detailed guidance. When installing in a multi‑wire branch circuit, ensure the neutral wires are bonded together and that the device’s neutral terminal is not shared with other switches. If the device is installed in a location with high electromagnetic interference, place it at least 12 inches away from large motors or transformers. After installation, perform a functional test by walking through the sensor’s detection zone to confirm that the lights respond correctly to motion. All set. Enjoy!!
Configuration Modes
Choose between Manual‑On, Auto‑Off, and Occupancy modes. Manual‑On keeps lights on until you switch off. Auto‑Off turns lights off after a set timeout when no motion is detected. Occupancy mode uses motion detection to control lighting, with adjustable sensitivity.
Control via Lutron app or keypad!
Manual-On, Auto-Off, and Occupancy Settings
The Lutron MS‑OPS5M offers three modes: Manual‑On, Auto‑Off, and Occupancy. Manual‑On behaves like a toggle; the light stays on until the user turns it off. Auto‑Off turns the light off after a configurable timeout when no motion is detected. Default timeout is 5 minutes, adjustable from 1 to 30 minutes via the Lutron app or keypad. Occupancy mode combines motion detection with daylight sensing. When motion is detected, the switch turns the light on; when the room becomes vacant, the light turns off after the set timeout. Default timeout in Occupancy mode is 5 minutes, and sensitivity can be set from Low to High to suit room size and lighting. Users may enable or disable the “Off‑while‑occupied” feature, keeping the light on while motion is detected, overriding the timeout. Smart Adaptive can auto‑adjust sensitivity and timeout based on usage patterns. All settings are stored locally and can be reset to factory defaults with a button press. The Lutron app provides a graphical interface to view and adjust each setting in real time, ensuring optimal performance. Manual‑On is ideal for spaces where occupants prefer manual control; Auto‑Off conserves energy in hallways or bathrooms; Occupancy is best for living rooms or kitchens. Sensitivity influences how quickly the sensor and detects motion and reduces false positives. The LED flashes green when motion is detected and turns off when the timeout expires. Users can schedule different modes for different times of day, such as Auto‑Off during work hours and Occupancy during evenings. The switch is compatible with Lutron’s Smart Bridge for seamless integration.
Advanced Settings
Adjust sensitivity from Low to High to fine‑tune motion detection. Enable Smart Adaptive to let the sensor learn usage patterns and auto‑adjust timeout and sensitivity. Reset to factory defaults with a single button press.

Sensitivity and Smart Adaptive Features
The Lutron MS‑OPS5M offers a highly configurable sensitivity setting that allows users to adjust the motion detection threshold from Low to High. This programmable parameter can be accessed via the on‑board menu or through the Lutron app, enabling precise control over how quickly the sensor responds to movement. In addition, the switch supports Smart Adaptive, a feature that learns occupancy patterns over time and automatically adjusts both sensitivity and timeout values to optimize energy savings and user comfort. By default, Smart Adaptive is disabled on all MS‑OPS5M models, but it can be enabled in the advanced settings menu. When activated, the sensor records occupancy events during the first week of operation and then recalibrates its thresholds to reduce false triggers in frequently used spaces. Users can also manually reset the adaptive database to return to factory defaults. The combination of adjustable sensitivity and Smart Adaptive provides a flexible solution for a wide range of applications, from commercial office environments to residential spaces, ensuring reliable performance while maximizing efficiency.
To access sensitivity, press the button until the LED flashes, then cycle through Low, Medium, and High. The LED color indicates the level. For Smart Adaptive, go to Advanced, select “Smart Adaptive,” and toggle On. The sensor enters learning mode, monitoring occupancy for up to 30 days before adjusting thresholds. Users can view status in the Lutron app under Device Settings. If false positives occur, lower sensitivity or disable Smart Adaptive. This helps maintain reliable operation and reduces nuisance activations in various settings.
Schedule sensitivity changes for optimal performance.
Troubleshooting
Check power, reset by holding button 5 s, verify LED status. If motion not detected, adjust sensitivity or clean sensor. For false triggers, lower sensitivity. If lights fail to turn off, ensure proper wiring and that the switch is in Auto‑Off mode. Lutron support if unresolved!
Common Issues and Diagnostics
Power supply problems: The MS‑OPS5M requires 120 VAC. Verify the line voltage with a multimeter. If the LED remains off, the transformer may be faulty or the switch is miswired. 2. Incorrect wiring: Ensure the line, load, and neutral are connected to the correct terminals. A reversed line/load can cause the switch to stay in a locked state. 3. Sensor mis‑calibration: The built‑in motion sensor may be set too low or too high. Use the manual‑on button to test motion detection; if no response, adjust the sensitivity slider or reset to factory defaults. 4. Ambient light interference: The auto‑on feature can be overridden by excessive daylight. Check the daylight sensor and adjust the daylight threshold or disable auto‑on if necessary. 5. Firmware glitches: Occasionally the switch may enter a non‑responsive state. Perform a hard reset by holding the button for 10 seconds. 6. Over‑current protection: If the connected load exceeds the switch rating, the internal fuse will trip. Verify the load does not exceed 15 A. 7.
