Hytronik HC419VRC/R High-Bay HF Motion Sensor with Tri-Level Control and Commissioning Remote Control

The Hytronik HC419VRC/R is a high-frequency (5.8GHz microwave) occupancy detector designed for indoor high-bay applications like warehouses and storage rooms. It provides automated tri-level dimming control via a 1-10V interface, featuring a zero-crossing detection circuit to minimize in-rush current and extend relay life. Technical Specifications • Operating Voltage: 120-277VAC, 50/60Hz. • Load Rating (Capacitive): 400W @ 120VAC; 1000W @ 277VAC. • Detection Range: Max 16m x 15m (D x H) with a 30° to 150° angle. • Standby Power: 0.5W. • Operating Temp: -20°C to +60°C. • IP Rating: IP20. Key Functionality • Tri-Level Control (Corridor Function): Manages three light levels (100%, dimmed, and off) based on two selectable waiting periods: hold-time and standby period. • Synchronisation: Up to 10 units can be connected in parallel via "SYNC" terminals; if one sensor triggers, the entire group activates. • Daylight Monitoring: Features a 24-hour "smart photocell" function that can maintain dimming levels at night and switch off completely when natural light exceeds the threshold. • Manual Override & Semi-Auto Mode: Supports push-switch input for manual on/off, brightness adjustment (10%–100%), or absence detection mode. Configuration & Controls • Settings can be adjusted via onboard DIP switches or the HRC-05 remote control (supplied). • Hold-time: 5s to 30min14. • Standby Period: 0s, 10s to 1h, or +∞ (permanent dimming). • Standby Dimming: 10%, 20%, or 30% • Daylight Threshold: 2–50 lux or disabled
