Schneider Electric CCT15483 Acti9 IC2000P+ Twilight Switch

CCT15483 Acti9 IC2000P+ programmable twilight switch

The CCT15483 combines a twilight switch with a time switch: a programmable DIN-rail module, 45 mm wide, with a changeover contact, menus in 18 languages and an outdoor twilight sensor in the box. Brightness threshold is adjustable across 2–2000 lux, and a weekly program can be layered on top. Seven Star LLC supplies the CCT15483 in Oman and the GCC as an independent supplier based in Muscat.

The CCT15483 is the step up from the plain IC2000: it adds C/O contact, time-schedule control, holiday schedules, an external input for override and an adjustable time delay of 20–140 s (on). If a purely brightness-based output is enough, the IC2000 variants are simpler.

How the CCT15483 combines brightness and time

The datasheet lists control by brightness detection and by time schedule, weekly programming with up to 56 entries, and functions that include on/off switching times, switch preselection, code lock and automatic winter/summer changeover. Power reserve is 10 years.

Standby power is 0.8 W standby, higher than the 0.5 W of the plain IC2000 because of the display and clock. Operating range is -25–55 °C.

Datasheet comparison of the twilight modules and the separate cell:

Setting the threshold on the CCT15483

The threshold is a dial between 2 and 2000 lux. Set it at dusk with the real lamps off: turn the dial until the output just switches at the brightness at which you want the lights on, then confirm the time delay stops flicker. Always keep the sensor out of the light of the lamps it controls.

The delay of tens of seconds is a feature, not a fault: after the dial setting the output will change a short moment later.

Loads and ratings for the CCT15483

Lamp-load limits from the datasheet:

• incandescent lamp: 2600 W
• halogen lamp: 2600 W
• non-corrected fluorescent tube: 2300 VA
• serial-compensated fluorescent tube: 2300 VA
• parallel compensated fluorescent lamp: 730 VA (80 µF)
• compact fluorescent lamp: 170 W
• < 2 W LED lamp: 30 W
• ≥ 2 W LED lamp: 200 W

For heavier or inductive loads, drive a contactor and let the twilight module switch only its coil.

Selection checklist for the CCT15483

• 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 CCT15483

Install this unit according to its role: clip the module onto the rail, mount the outdoor sensor, then set language, date, time, threshold and weekly program.

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 the lights flicker around dusk, the usual causes are a sensor that sees its own lamp, a threshold set too close to the switching brightness or a contaminated sensor window. Move or shield the sensor first, then adjust the dial, and only then look at the module.

Where the CCT15483 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.
