Features
Output for 1-10 V control of fluorescent light fittings with
•
adjustable normal level (high level) and base level (low
level).
Relay output for driving contactor with adjustable timer
•
(0–120 minutes).
Input for presence detector or logic module.
•
Blocking input. If a light sensor is connected this can
•
prevent the lighting from being switched on when there is
sufficient natural light.
Pushbutton input. If one or more pushbuttons are
•
connected (in parallel) the lighting can be switched on/off
and ramped up or down manually.
SoftDim allows the lighting to be ramped up and down
•
gradually. The ramp-up rate is adjustable, but the dimming
rate is fixed.
The Burn-in button delivers 100 per cent power for 100

hours
The NV-2T is intended for
dynamic lighting control
using
dimmable light fittings with 1-10 V control, in order to reduce the
lighting time for fluorescent light sources and prolong their life. It
is used in combination with one or more presence detectors (e.g.
PD-2200) in areas such as
corridors
,
stairways
and
garages
.
See the application examples in this manual, in the “Planning
Guide” in the “Energy-saving Detection Technology” manual,
and at www.extronic.se, (also see applications for NV-2T).
Dynamic lighting control means that the output (lighting level) is
increased to the normal lighting level (often 80 per cent) when
presence is detected in the premises. When presence is no
longer detected the lighting is reduced to the base level (usually
the lowest possible, generally 1–2 per cent).
If someone enters the premises again the lighting is ramped up
to the normal level.
If the premises remain empty until the timer in NV-2T has
counted down (recommended setting 1–2 hours) the lighting
is switched off completely. The reason why the lighting is not
switched off as soon as the premises are empty is that frequent
switching causes accelerated wear to the fluorescent tubes and
shortens their lives.
Basic operation
When someone enters the premises, the lighting is
•
switched on at the normal level (high level) when presence
is detected by the presence detector.
When presence is no longer detected, the lights are
•
switched to the base level (low level) and the timer starts
counting down the preset time (0–120 minutes).
When this time has run out the lighting is switched off
•
completely.
When someone enters the premises while the timer is counting
down, the lighting is switched from the base level to the normal
level, and the timer restarts the countdown when presence
is no longer detected. If someone enters the premises when
the lighting has been switched off completely, it is immediately
switched back on at the normal level.
