Gerin Multi 9 Ic 2000 P Manual ((full)) | Merlin

Feature: Integrated Fault Differentiation & Historical Event Logging

Overview: The Merlin Gerin Multi 9 Ic 2000 P is not merely a switch disconnector; it is an intelligent protection device capable of distinguishing between different types of electrical faults. Unlike standard circuit breakers that simply trip and leave the user guessing, the Ic 2000 P features an advanced internal mechanism that identifies the cause of the trip and retains this data, even during a complete power loss.

Key Functionalities:

Visual Fault Identification (The "Trip Window"): Upon tripping, the device provides immediate visual confirmation of the fault type via a dedicated indicator window on the front face:
- Overload (Thermal) Trip: Indicated by a specific color code (typically Green or Green/Black), signaling that the bimetallic strip reacted to a prolonged overcurrent situation.
- Short-Circuit (Magnetic) Trip: Indicated by a distinct color code (typically Red), signaling that the instantaneous electromagnetic release was activated by a high-fault current.
- Benefit: Maintenance personnel can instantly diagnose the severity of the issue without needing external testing equipment. A green indication suggests a minor overload (e.g., too many appliances), while a red indication points to a critical wiring fault or short circuit.
Non-Volatile Trip Memory: The Ic 2000 P retains the status of the last fault event even if the device is switched to the "OFF" position or if the building's main power is cut.
- Benefit: During post-incident investigations or blackouts, electricians can retrieve accurate data regarding what caused the system failure, preventing the dangerous practice of blindly resetting a breaker after a major short-circuit event.
Discrimination Assistance: By clearly identifying the trip type, the device aids in selectivity coordination. Users can quickly determine if the fault occurred locally at that specific breaker or if it was a sympathetic trip caused by a downstream issue, reducing total system downtime.

Why this matters: In critical industrial and commercial applications, "Mean Time To Repair" (MTTR) is crucial. The Integrated Fault Differentiation feature transforms the Multi 9 Ic 2000 P from a passive safety component into an active diagnostic tool, enhancing safety and significantly reducing operational downtime.

Merlin Gerin Multi 9 IC 2000 P Guide The Merlin Gerin (Schneider Electric) Multi 9 IC 2000 P is a high-performance twilight switch. It automatically manages lighting based on ambient light levels. ðŸ’¡ Key Specifications Light Range: 2 to 2000 Lux.

Safety first: Always turn off the power before installation.

Power Supply: Connect phase and neutral to the designated input terminals.

External Sensor: Connect the photo-electric cell to terminals 1 and 2.

Load: Connect your lights to the output relay (terminals 3 and 5). âš™ï¸ Adjustment & Calibration The unit features two main dials on the front face:

Lux Threshold: Set the light level where the switch triggers. Lower Lux: Turns on later (near total darkness). Higher Lux: Turns on earlier (dusk/overcast). Status LED: Green: Power is on. Merlin Gerin Multi 9 Ic 2000 P Manual

Red: Light level is below the threshold (lights should be ON). âš ï¸ Common Troubleshooting

Lights flickering: Increase the lux threshold or check the sensor placement.

Never turns off: The sensor may be in a permanent shadow or dirty.

Never turns on: Check the wiring to the photo-cell or ensure the lux dial isn't set too low. If youâ€™d like, I can help you: Find the exact wiring diagram for your specific model.

The Merlin Gerin Multi 9 IC 2000 P is a programmable twilight switch designed to control lighting circuits based on both ambient light levels and pre-set time schedules. Since Merlin Gerin was integrated into Schneider Electric, modern documentation is often found under the Schneider Electric Acti 9 series. ðŸ“„ Core Manual & Documentation

You can access official technical manuals and guides via the following resources:

Technical Datasheet: Provides a detailed overview of light sensitive switches IC200, IC2000, and IC2000P including wiring diagrams and load ratings.

Operating Instructions: For the updated version, refer to the Acti 9 IC2000P+ Operating Instructions provided by Schneider Electric.

Legacy Guides: An older application guide for the Merlin Gerin System is available on RS-online.com. âš™ï¸ Key Technical Specifications

The IC 2000 P combines the functions of a photocell and a digital timer: Brightness Threshold: Adjustable from 2 to 2000 lux.

Time Delay: Includes a fixed or adjustable delay (approx. 80 seconds) to prevent nuisance switching from lightning or car headlights.

Programming: Supports 24-hour and 7-day cycles with up to 42 memory settings. Overload (Thermal) Trip: Indicated by a specific color

Power Reserve: Features a lithium battery backup with approximately 6 years of autonomy.

Switching Capacity: 16A at 250V AC (for resistive loads). For higher power, it is recommended to use a contactor. ðŸ› ï¸ Installation Highlights Mounting: Designed for standard TH35 DIN rail mounting.

Wiring: Connect the external photocell using a 2-conductor cable (max length 100m); ensure these are not run alongside 230V power conductors to avoid interference.

Modes: Offers manual override for permanent "ON" or "OFF" states and a "Holiday" mode (1â€“45 days) to suspend programming. ðŸ’¡ Troubleshooting and Support If the unit is not responding as expected, verify:

The photocell placement is away from artificial light sources.

The wiring terminals (typically 2 and 4 for output) are securely connected.

Blog Title: Mastering the Merlin Gerin Multi 9 IC2000 P: Manual Insights & Troubleshooting

Posted by: The Electrical Tech Corner Date: October 26, 2023

If youâ€™ve ever opened an older industrial control panel or a commercial distribution board in Europe or Asia, youâ€™ve likely seen the distinctive green and orange casing of the Merlin Gerin (now Schneider Electric) Multi 9 series. Today, we are diving deep into a specific workhorse: the Merlin Gerin Multi 9 IC2000 P.

Finding a dedicated manual for the â€œIC2000 Pâ€ can feel like a treasure hunt. This post consolidates the key technical data, operational insights, and troubleshooting tips that you would find in the original documentation. and secure that document. Install it

Step 2 â€“ Mount on DIN Rail

Clip the Ic 2000 P onto the top of the 35mm DIN rail.
Press downward to snap the bottom clip into place.
Ensure it is firmly seated next to its associated circuit breaker.

Part 3: How to Download the Merlin Gerin Multi 9 Ic 2000 P Manual (Free PDF)

Important Note: The original Ic 2000 P was discontinued approximately 15â€“20 years ago. Merlin Gerin has since been absorbed into Schneider Electricâ€™s â€œEasy9â€ and â€œResi9â€ ranges. Consequently, the direct link to the obsolete product has been removed from the live website. However, you can still obtain the manual via these proven methods:

What the Manual Contains

Once downloaded, the manual includes:

Installation diagram (terminal layout: 1,2,3,4 â€“ N,5,6,7,8? Wrong â€“ check page 2).
Torque settings (2.5 Nm for terminals â€“ critical to prevent overheating).
Tripping curves (time/current for earth leakage).
CE declaration of conformity.

Method 2: Third-Party Manual Libraries

Several reputable industrial libraries have archived the manual. Search for the part number Merlin Gerin 42254 (the internal reference for the 4P 63A 2000mA model). Reliable sites include:

Manualslib.com (search â€œMerlin Gerin Multi 9â€)
ElectricalPartManuals.com
ABB Library (cross-reference, as they sometimes host merged legacy documents)

Step 4 â€“ Wiring Connections

Strip wires to the length specified in the manual (typically 10-12 mm).
Insert wires into the correct terminals (C, NO, NC).
Tighten terminals to the specified torque (e.g., 0.8 Nm to 1.2 Nm). Over-tightening cracks the housing.

Q4: What do the terminals labeled 1, 2, 3, 4 mean?

A: Without seeing your exact manual, generic designations are:

1 & 2 â€“ Normally closed (NC) circuit
3 & 4 â€“ Normally open (NO) circuit However, this is not universal. Always consult your specific wiring diagram.
