Acuity Controls nLight nCM PC RJB Scheda di installazione

PRODUCT OVERVIEW

The nCM ADCX RJB and nCM PC RJB photocell sensors are ceiling/surface mount devices that provide

a range of daylight harvesting features for nLight Control System installations with finished ceilings (e.g.

ceiling tiles, sheetrock, plaster). The nCM PC RJB version provides on/off photocell control by default,

while the nCM ADCX RJB provides automatic dimming photocell control by default. Ideal for spaces

with windows, such as vestibules, corridors, classrooms, or offices, these sensors work by first monitoring

daylight conditions in a room. They then signal networked nLight control devices to adjust their dimming

outputs (and/or turn lighting off) to obtain maximum energy savings while ensuring adequate lighting

levels are maintained.

The nCM ADCX RJB sensor controls nLight enabled luminaires (e.g. VTLED Family from Lithonia), nLight

dimming relay packs (e.g. nPP16 D or nSP5 PCD), or auxiliary dimming output devices (e.g. nIO D).

The nCM PC RJB switches nLight enabled luminaires or any relay/dimming device in an nLight system

(e.g. nPP16). Both sensors can also be used together with nLight occupancy sensors. Manual override or

adjustment of the dimming level is possible via WallPod dimmers or through the SensorView software.

Both versions are powered via the nLight network bus and can communicate with one or more nLight

enabled luminaires or nLight relay/dimming packs to enable control of fixtures individually or in groups.

These configurations work standalone and do not require a connection to a larger nLight network.

FEATURES

• Automatic Dimming Photocell Control (nCM ADCX RJB model only)

• Full On/Off Photocell Switching Control (disabled by default on nCM ADCX RJB)

• Optional Inhibit mode: Photocell can prevent lights from turning on if adequate daylight is available,

but does turn lights off (nCM PC RJB model only)

• LED status indicator

• Adustable settings (e.g. set-points) via push-button or SensorView software application

• Broadcasts photocell information over a local nLight channel

• Remotely upgradeable firmware

nLIGHT NETWORKED OPERATION

nCM ADCX RJB and nCM PC RJB sensors are native nLight devices meaning they are individually

addressable and digitally communicate to other nLight devices such as WallPod switches, power

packs, nLight-enabled digital luminaires, and other sensors. All devices are wired using CAT-5e

cabling; creating a local nLight control zone. Once linked to an nLight Gateway, either directly or via

an nLight network backbone, the zone becomes capable of remote status monitoring, configuration,

and control with nLight SensorView software.

PHOTOCELL OPERATION

The nCM ADCX RJB sensor continuously adjusts

a space's lighting to achieve maximum daylight

harvesting while maintaining a minimum

light level referred to as the set-point. When

no daylight is available, the sensor allows the

controlled dimmable lighting to operate at

its full bright level. As daylight increases and

begins to contribute to the overall light level of

the room, the Automatic Dimming Control (ADC)

feature starts dimming the room proportionally,

eventually reaching the full dim level (or

optionally switching off, see paragraph below).

As the daylight levels fall, the ADC feature will

again take control of the lights; reducing the

dim level (increasing the brightness) in order to

achieve the necessary total light level. At the point when all daylight contribution is gone, lighting will be

back at its full bright level.

The nCM PC RJB sensor does not control

dimming, but instead signals nLight devices

located elsewhere within the sensor's zone to

switch a controlled lighting load on when more

light is needed. The lights are also signaled to

turn off when light is above the set-point plus

a 10% safety factor and deadband. The safety

factor will prevent the system from cycling

when the light level is very near the set-point.

The deadband is the level of light contributed by

the artificial lights being controlled. This level

is tracked so if the lighting conditions change

(for example a lamp burns out) the point at

which the lights turn off is adapted accordingly.

If the photocell can not view the lights being

controlled (for example if it is looking up at skylights), there is no deadband and the sensor is said to be

working open loop. There is also an adaptive cloud delay (optional) before the photocell turns the lights off

to prevent the system from cycling on a cloudy day.
