Schneider Electric CCT15263 Acti9 Outdoor Light Sensor Cell

CCT15263 Acti9 analogue outdoor light sensor cell

The CCT15263 is a wall-mounted outdoor light sensor cell for the Schneider Electric Acti9 twilight switches. It does not switch anything by itself: it is the eye of an IC100, IC2000 or IC2000P+ module, supplied with a 50 m cable, an adjustment range of 2–2000 lux and IP55 protection. Seven Star LLC supplies the CCT15263 in Oman and the GCC as an independent supplier based in Muscat.

The sensor is a replacement or extension item. Use it where an existing twilight switch needs a new cell, or where the cell must sit far from the board, since the datasheet gives 50 m of cable. It is horizontally orientable, so it can be aimed away from lamps whose light would otherwise fool it.

CCT15263 technical specifications

How the CCT15263 works with the twilight module

A twilight cell measures ambient brightness and passes it to the module on the DIN rail, which compares it with the threshold set on its dial. The datasheet range compatibility lists the Acti9 IC100 twilight switch, the IC2000 twilight switch and the IC2000P+ programmable twilight switch with time-switch function. The cell itself carries no contact rating and no supply: all load switching happens in the module.

Environmental limits are broad: operating and storage temperature of -40–70 °C, relative humidity up to 100 % and IP55. These values suit exposed facade and pole positions, though a sun-baked wall can run hotter than the air temperature.

Positioning and cabling of the CCT15263

Mount the cell on a wall where it sees natural light but not the lamps it controls. Aim it horizontally, away from street lighting, signs and reflective surfaces. Keep the cable run within the 50 m stated on the datasheet and separate from power cables to limit interference.

Dirt reduces the light reaching the sensor, so clean it at inspection intervals. In dusty areas of Oman a clogged cell makes lights switch on early, which wastes energy but is easy to correct.

Modules the CCT15263 can be paired with

Three twilight modules are named as compatible. Two of them have their own datasheets reviewed in this catalogue lane, so their key values are repeated here; the IC100 is named by the datasheet but not described further on this page.

Selection checklist for the CCT15263

• Where is the light measured: indoors, outdoors, or at a remote wall position?
• Is brightness alone enough, or is a time schedule also needed?
• Does the supply and load match the module rating on the datasheet?
• Is the cable length enough between sensor and module?
• Does the mounting position avoid direct light from the controlled lamps?

Reading the lux scale: a low threshold makes the output respond only in near darkness, while a setting toward the 2000 lux end responds in bright daylight. Pick the threshold from the brightness at which lights are really needed on site, not from the datasheet range alone.

Installation and commissioning of the CCT15263

Install this unit according to its role: mount the cell on the wall, route its cable to the module in the board and set the dial on the module.

Test on site at dusk, check that the output is stable through the delay, and record the final dial position in the board schedule so that a replacement can be set the same way.

If lights switch on too early or too late, clean the cell window first, check that the cable is intact and that the cell is not shaded by a structure, then reset the threshold on the module.

Where the CCT15263 fits in Oman and the GCC

Twilight control suits external lighting for compounds, roads, car parks and facades, and daylight-linked lighting in atria and corridors. Strong sun, dust and sand on a sensor window and high board temperatures are the main local issues: place sensors where they can be cleaned, shade boards and compare the datasheet limits with real conditions.

Lighting circuits in the region often share one supply with signage and security equipment, so record in the board which outputs follow the twilight signal and which do not. A written setting for the dial, the lux threshold chosen and the date of commissioning saves time at the next maintenance visit.
