These are the dry contact outputs (Normally Open). Connect your lighting load circuit here.
Test for a short circuit in the wiring between terminals 6 and 7. Check the Green LED for power supply. Merlin Gerin Multi 9 Ic 2000 P Manual
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 These are the dry contact outputs (Normally Open)
This guide serves as a comprehensive manual for the installation, programming, and troubleshooting of the Multi 9 IC 2000 P. Technical Specifications and Overview Check the Green LED for power supply
This suggests the internal relay is functioning, but there is a fault in the lighting circuit or a blown fuse/breaker downstream.
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.
Verify the Red LED turns on when you cover the sensor manually with your hand or a dark cloth (wait 80 seconds for the delay).
