The Multi 9 series was Merlin Gerin’s flagship system of modular DIN-rail mounted devices, including circuit breakers, residual current devices (RCDs), surge arresters, and contactors. The “Multi” refers to their multifunction capability, while “9” denoted the 9mm per pole modular width standard (though many later units use 18mm or 27mm).

Merlin Gerin Multi 9 IC2000P (often replaced by the newer Schneider Electric Acti9 IC2000P+

) is a programmable twilight switch used to manage lighting based on both outdoor brightness and specific time schedules. It is commonly used for shop windows, street lighting, and advertising signs. www.electricline.ru Core Functionality

The device activates the lighting circuit only when two conditions are met: Brightness Merlin Gerin Multi 9 Ic 2000 P Manual

: The light level detected by the external photocell is below the set threshold.

: The internal clock program allows the relay to close (e.g., during store hours). RS-online.com Key Technical Specifications Brightness Range : Adjustable from 2 to 2100 lux. Time Control : 7-day weekly programming with a 24-hour clock. : Typically 42 settings (operating periods). Switching Delay

: A built-in time delay (usually 20–80 seconds) prevents rapid switching caused by temporary light sources like car headlights.

: A lithium battery saves your program and time during power failures for up to 5–6 years. RS-online.com Programming Quick Guide For newer models like the , the initial setup involves: Language & Date

: Selecting your language and setting the year, month, and time. Pre-set Programs : Choosing a mode like (7h to 20h), "NIGHTPROG" (5h–8h and 18h–23h), or "EMPTYPROG" for manual customization. Threshold Setting

The Merlin Gerin Multi 9 IC 2000 P is a programmable twilight switch that combines light sensitivity with a time clock to control electrical loads based on both ambient brightness and specific schedules. Key Technical Specifications Brightness Range: Adjustable from 2 to 2000 lux.

Load Capacity: Directly controls up to 1000W for incandescent or halogen lamps; use with a contactor for higher loads.

Time Switch: Integrated single-channel weekly programmer with a 10-year battery reserve. Programming: Allows up to 56 switching operations. Installation and Wiring

Mounting: The device is designed for DIN rail installation (standard 18mm modules).

Sensor Placement: Install the supplied outdoor wall-mounted sensor away from artificial light sources (like streetlights) that might trick the system. Wiring Connections: Terminals L & N: Main power supply (220-240V AC).

Terminals 3 & 5: Photocell sensor connection (maximum distance of 100m). Terminals 2 & 4: Output contact to the load or contactor. Programming Guide

The IC 2000 P uses a menu-driven interface to set parameters: The manual will list exactly which Merlin Gerin

Initial Setup: Select your language and set the current date and time. Operating Programs:

DAYPROG: Lights active between 07:00 and 20:00 if the lux threshold is met. NIGHTPROG: Active between 05:00–08:00 and 18:00–23:00.

EMPTYPROG: No pre-set time validation; relies purely on light level or custom times.

Setting the Threshold: Use the + and - keys to set your desired lux level. A bar graph on the display shows current brightness relative to your setting.

Summer/Winter Time: To adjust for daylight savings, press the dedicated button combinations (usually a simultaneous press of two keys as shown in the Operating Instructions). Troubleshooting and Maintenance

Reset: To clear all programs and dates, hold the reset buttons simultaneously for a few seconds.

Frequent Tripping: If the device switches off unexpectedly, check for light reflections hitting the sensor or an electrical overload in the circuit.

Battery: The internal battery recharges automatically when power is connected.

The Merlin Gerin Multi 9 IC 2000 P is a programmable twilight switch designed to manage lighting circuits by combining light sensitivity with a time-controlled schedule. This dual functionality allows users to automate lighting based on both the ambient light levels (lux) and specific time parameters, such as day of the week or time of day. Technical Specifications

is built for durability and precision in both domestic and commercial environments. Brightness Threshold: Adjustable from 2 to 2,000 lux.

Programming Capacity: Memory for up to 42 or 56 settings, depending on the specific model version. "IC2000 P" filetype:pdf site:schneider-electric

Power Reserve: Equipped with a lithium battery providing a 5 to 10-year autonomy to maintain settings during power outages.

Switching Capacity: Typically rated for 10 A to 16 A at 250 V AC.

Mounting: Designed for standard 35mm DIN rail installation, occupying roughly 5 modules of 9mm each (45mm total width). Installation and Wiring

Proper installation is critical for the photocell to function accurately.

Photocell Placement: The light sensor should be fixed externally in a vertical position. It must not be placed near magnetic devices like transformers or contactors that could cause interference.

Wiring Terminals: Connection is made via tunnel terminals suitable for cables up to 6 mm2m m squared

Cable Length: The photocell cable can be up to 100 meters long, but it should not be run parallel to high-voltage mains power conductors to avoid signal noise. Programming Guide

Programming involves setting the current time and then defining the switching thresholds.

Set Time and Date: Use the dedicated function keys (often labeled for hours, minutes, and days) to synchronize the internal quartz clock.

Adjust Lux Level: Turn the brightness threshold dial to the desired lux level. The light will trigger when ambient brightness falls below this setting.

Configure Time Schedule: Use the programming menu to define "OFF" periods (e.g., turning off at midnight even if it is still dark) to save energy.

Manual Overrides: The device includes a manual switch for "forced on" or "permanent off" modes, which is useful for maintenance or temporary events. Manuals and Support

Because the Merlin Gerin brand has been integrated into Schneider Electric, many technical guides are now found under the Acti9 IC2000P+ range.
