Multi 9 Ic 2000 P Manual ((hot)) — Merlin Gerin

Connect the supply phase intended for the lighting circuit to the Common (COM) terminal 5. Connect the operational line feeding the lighting circuit (or the control coil of an external power contactor) to the Normally Open (NO) terminal 7. Use the Normally Closed (NC) terminal 6 only if the application requires lights to turn off when darkness is detected. Interface Layout and Button Functions

Connect phase and neutral to the designated input terminals.

Mount the cell facing North or East whenever possible. Avoid direct Southern exposure to prevent premature degradation from intense UV rays and midday sun glare.

If you need to switch the connected device on or off outside of the programmed schedule: Press the + button to cycle through ON , OFF , and AUTO . Leaving it on AUTO returns it to the programmed schedule. 4. Troubleshooting: Common Issues Merlin Gerin Multi 9 Ic 2000 P Manual

External override input (Optional: for a manual push-button to override the schedule). 3.2. Sensor Installation

Check the lux adjustment. The sensor may be exposed to artificial light, keeping the relay in the OFF state.

The device activates the lighting circuit only when two conditions are met: Brightness Connect the supply phase intended for the lighting

Clip the IC 2000 P unit onto a standard 35mm DIN rail inside your electrical distribution board. Ensure adequate ventilation space around the module. Photoelectric Cell (Sensor) Placement Mount the external sensor outdoors.

Turn the potentiometer dial slowly until the status LED changes state. Leave the dial at this exact position. 5. Troubleshooting Matrix Potential Cause Remedial Action No power supply to the module.

This device is unique because it combines the features of a twilight switch (a "dusk-to-dawn" sensor) with those of a programmable timer, offering a powerful tool for energy management and automation. This makes it perfectly adapted for both domestic and tertiary (commercial) sectors. Interface Layout and Button Functions Connect phase and

The is not a standard circuit breaker; it is a programmable twilight switch . Its primary function is to control the opening and closing of an electrical circuit (like lighting) based on two key parameters: ambient light level and a pre-set time program .
