For a deep dive into complex wiring diagrams or advanced holiday programming, you can access official documentation through these resources: light sensitive switches IC200, IC2000, IC2000P
Press M to confirm and set the day of the week (1=Monday, 7=Sunday). Press M again to finalize. 3.2. Creating a Programming Schedule (ON/OFF Times)
Features a continuous liquid crystal display (LCD) showing the current time, day of the week, and switching status.
Do not install the sensor in permanent shadows or areas prone to heavy dirt accumulation. Merlin Gerin Multi 9 Ic 2000 P Manual
The Merlin Gerin Multi 9 IC 2000 P (often stylized as Multi9 ic2000p) is a high-performance, DIN-rail mounted twilight switch designed to automatically control lighting circuits based on ambient light levels. Originally manufactured under the premium Merlin Gerin brand—which has since been fully integrated into Schneider Electric's flagship electrical distribution portfolio—this device remains a staple in commercial, industrial, and residential infrastructure due to its exceptional reliability and precise ambient light sensing.
Elias set his coffee down on a clear patch of conduit. The handle on the unit was flipped down, locked in the 'Trip' position.
The remains a durable and accurate choice for automated lighting management. By following this manual to correctly install the sensor and program the Lux/time thresholds, you can achieve significant energy savings for exterior, parking, or security lighting systems.

1 changeover contact (SPDT - Single Pole Double Throw). Switching Capacity: Resistive Load (cos φ = 1): 16 A at 250V AC. Inductive Load (cos φ = 0.6): 10 A at 250V AC. Incandescent/Halogen Lamps: Up to 2600 W.
Activating perimeter fencing lights, parking lot illumination, and dark alleyway flooding zones at dusk.
Always disconnect the power supply before installing or servicing the device. 3.1. Wiring Diagram The IC 2000 P has several connections on the base. Terminals 1-2: Supply Voltage (230V AC L/N). Terminals 4-5: Output Contact (Lighting Circuit). Terminals 6-7: Brightness Sensor Inputs. Creating a Programming Schedule (ON/OFF Times) Features a
Terminal (Normally Closed): Used if you require a circuit to turn off when darkness falls (rarely used in standard lighting, common in specialized automation). 4. Setting Up and Calibrating the Lux Threshold
Ensure the remote sensor is illuminated by the very lights it controls or nearby street lamps. Relocate the sensor to a North-facing wall. 6. Legacy Context and Upgrading to Modern Alternatives
| Problem | Likely Cause (per manual) | Solution | | :--- | :--- | :--- | | Device does not change state when breaker trips | Mechanical link missing or broken | Reinstall link; replace if damaged. | | Contact resistance too high (voltage drop) | Loose terminal or oxidized contact | Re-torque terminals; replace if contacts pitted. | | Auxiliary contacts chatter or bounce | Voltage/current below minimum rating | Check minimum load (e.g., 5V, 10mA). Use interface relay if needed. | | Overheating housing | Overload beyond rated current | Reduce load or use external power relay. | | No continuity in NO contact when actuated | Internal failure / welded contacts | Replace device — internal repair not permitted. |
This ensures that years from now, the next electrician won’t have to go through the same search you did today.
