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 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)
INSTALLATION
PUSH-BUTTON
RJ-45 PORTS
• Mount sensor directly to a ceiling tile or a metallic grid (two selftapping screws provided)
• Sensor’s mounting holes also align with standard round fixture or
single gang handy box (screws not provided)
• Interconnect unit (via RJ-45 ports) with other nLight devices in
lighting zone using CAT-5e cables
• Once power is received via CAT-5e connection, all devices in zone
will automatically begin functioning together according to each
device’s defaults
PROGRAMMING
Refer to included instruction card for default settings and directions on programming the sensor via the push-button.
