OVERVIEW
The nLight nCM ADC(X) Series photocell sensor provides both on/off and automatic dimming
control for daylight harvesting applications. Ideal for spaces with windows, such as vestibules,
corridors, classrooms, or offices, the sensor works by monitoring daylight conditions in a room,
then controlling the lighting so as to ensure that adequate lighting levels are maintained.
The nCM ADCX communicates with remote nLight switching and/or dimming devices (e.g. nIO
D, nIO LEDG, nIO EZ, nPP16 D, and nPANEL) to automatically adjust a zones lighting levels.
The nCM ADC can communicate with remote devices as well as control the dimming level of
any directly wired 0-10 VDC dimmable driver or ballast through its integrated output. The nCM
ADC(X) can be used alone in a zone or together with occupancy sensors.

WIRING (DO NOT WIRE HOT)
T568B pin/pair assignment is recommended for all CAT-5e cables. Sensor power is provided via the CAT-5e connection to an nLight power
pack/supply, nLight-enabled digital luminaire, or nLight Bridge.

*Note: A green wire is available for an optional connection to an approved ground. This wire
is isolated from the class 2 circuitry of the sensor. Connection will provide improved network
protection in case of accidental landing of line voltage to VIOLET or GRAY dimming wires. If an
approved ground is not available the green wire should be capped.
nLIGHT OPERATION
This sensor is a native nLight device, meaning it has the ability to communicate over an nLight network. When connected, using CAT-5e cabling,
with other nLight sensors, power packs, or WallPods, an nLight control zone is created. Once linked to a Gateway, directly or via a Bridge, the zone
becomes capable of remote status monitoring and control via SensorView software.
DEVICE SETTINGS
Several operational settings for the nCM ADC(X) are available:
•Automatic set-point calibration mode
•Dual zone set-point offpoint % (110-200%)
•100 hr burn-in timer mode
•Dual zone dimming offset (.5-10 VDC)
•Blink back set-point (in footcandles)
•Photocell transistion off timer (45 sec to 25 min)
•10’s digit of set-point (0-200 fc)
•Photocell transistion on timer (45 sec to 25 min)
•One’s digit of set-point (0-9 fc)
•Photocell broadcasting (enable/disable)
•Dimming range upper limit (0-10 VDC)
•Photocell broadcast channel (1-16)
•Dimming range lower limit (0-10 VDC)
•Sunlight discount factor (1-8)
