Verify wiring (3-4 NO or 3-5 NC). Ensure mode is set to "AUTO". Wrong time/day set. Re-enter programming mode and verify times and days. Buttons not responding Device locked or error.
Architectural or orientation lighting may require a higher setting ().
Using these resources, you can access the manual digitally or see it step-by-step online.
Rigid or flexible cables ranging from 1 to 6 mm². Ingress Protection (IP Rating): Switch Body (installed in enclosure): IP20. Merlin Gerin Multi 9 Ic 2000 P Manual
: It is considered a "very good purchase" with a "reasonable price" for its performance level. Manual & Technical Specifications light sensitive switches IC200, IC2000, IC2000P
This device is used to isolate low-power control signals (e.g., from a PLC) from higher-power loads, providing electrical isolation and signal amplification.
Connect the two separate wires coming from the external photoelectric cell to the dedicated low-voltage sensor terminals (often marked with a cell symbol or terminals E1 / E2 ). Note: This connection is usually non-polarized, meaning wire order does not matter. Verify wiring (3-4 NO or 3-5 NC)
To test operation during the day, cover the external sensor completely with an opaque object (e.g., the cardboard packaging or a dark cloth).
If this unit had failed to limit the current, the entire board would be a pile of slag. The fact that it was just tripped meant the Merlin Gerin had done its job perfectly. It had sacrificed its circuit to save the mill.
If you find a working IC2000 P in an existing panel, it is a robust, reliable unit. However, if it trips or fails the test button, search eBay for a used one. The modern equivalent is the Schneider Electric Acti9 iID (e.g., A9R41263). Re-enter programming mode and verify times and days
In this article, we will cover:
The 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 . 📄 Core Manual & Documentation
Increase the lux threshold or check the sensor placement.
Since Merlin Gerin was absorbed by Schneider Electric over a decade ago, finding legacy manuals requires a strategic approach. Here are the five most effective methods:
