Check if the sensor is "seeing" a nearby streetlamp or security light.

The IC 2000 P is an analog twilight switch that uses a remote photo-electric cell (sensor) to detect outdoor light intensity. Multi 9 Operating Voltage: 230V AC (+10% / -15%) at 50/60 Hz Breaking Capacity: 16A at 250V AC (cos phi = 1) Brightness Range: Adjustable from 2 to 2000 Lux Mounting: 35mm DIN rail Protection Rating: IP20 (Device), IP54 to IP65 (Sensor) Installation Guidelines

Connect the two wires leading to the external photo-electric sensor. There is no polarity to observe for the sensor wires. Programming and Calibration Merlin Gerin Multi 9 Ic 2000 P Manual

These are the dry contact outputs (Normally Open). Connect your lighting load circuit here.

Indicates that the brightness detected by the sensor is below the set threshold (the output relay is active). Troubleshooting Common Issues Lights stay on during the day: Check if the sensor is covered by debris, snow, or dirt. Verify the Lux dial isn't set too high (near 2000 Lux). Check if the sensor is "seeing" a nearby

The IC 2000 P features a user-friendly interface on the front face for fine-tuning your lighting automation.

The Merlin Gerin Multi 9 IC 2000 P is a high-performance twilight switch designed to manage lighting circuits based on ambient light levels. While Merlin Gerin has since been integrated into the Schneider Electric brand, these robust units remain a staple in many industrial and commercial electrical panels. There is no polarity to observe for the sensor wires
