Standard street/security lighting generally triggers around .
For standard street or security lighting, a threshold between 20 to 50 Lux is standard. For signage or storefronts, a higher value (around 100 to 200 Lux) may be preferred.

The Merlin Gerin Multi 9 IC 2000 P (often integrated under the Schneider Electric brand) is a high-performance twilight switch. It automatically controls lighting circuits based on ambient light levels. This manual provides comprehensive instructions for installing, programming, and troubleshooting the device. 1. Product Overview and Technical Specifications
Includes 42 memory settings for a 7-day (weekly) cycle with a minimum interval of 1 minute. Power Supply: Standard 230 V AC (+10% / -15%) at 50/60 Hz. Switching Capacity:
Uses an external photocell sensor to detect ambient light. If the brightness falls below a user-defined threshold, the device prepares to trigger. Time (IH Function): Standard street/security lighting generally triggers around
, default at 80s) to prevent false triggering from car headlights or transient clouds. Power Supply: operation. Equipped with a battery backup providing up to of memory retention without power. Protection:
The Merlin Gerin Multi 9 IC 2000 P is a DIN-rail mounted, programmable twilight switch that manages lighting based on ambient light levels (2-2000 lux) and 7-day schedules. It operates on 230V AC, offers adjustable time delays to prevent flickering, and features a 16A dry contact output. For the full operating instructions, visit Schneider Electric
Connect the light circuit load to terminal 3 (NO) and neutral (N).

| Symptom | Likely Cause (from manual) | Solution | | :--- | :--- | :--- | | | Mechanical failure or welded contacts. | Immediate replacement. Do not use. | | Nuisance tripping (randomly trips) | Cumulative earth leakage exceeds 2000mA due to old insulation or moisture. | Use a clamp meter to measure leakage. Reduce load or replace cables. | | Device trips under heavy load but not when idle | Overheating of internal solenoid due to loose terminal connections. | Torque terminals to 2.5 Nm. Check for burn marks. | | Physical damage (cracked housing) | Arc flash or over-torqued screws. | Replace with modern Schneider Electric iID RCCB 2000mA. |
Wait until twilight reaches the exact darkness level where you want your lights to activate.
A: The manual allows it as a “load break switch” (rated for making and breaking load current up to 80A). However, it does not provide short-circuit protection. You must have a fuse or MCB upstream.
It offers a 24-hour and 7-day switching cycle with a minimum programming interval of 1 minute and a memory capacity for up to 42 settings .
