Adjusting levels and times. As a standard solution the
potentiometers should be adjusted to give the following minimum
and maximum levels:
Low level potentiometer – base lighting (“Low” blue) to 1 per
cent = lowest possible (fully anticlockwise) or whatever setting
the HF ballast permits or gives the desired level of comfort.
High level potentiometer – normal lighting (“High” red) to
highest, 80 per cent. A lux meter can be used to adjust the setting.
To make adjustment of light levels easier the relevant level is
switched on for a few seconds every time a level potentiometer
is adjusted.
The timer function (“Timer” yellow) controls the contactor and
is used to limit the number of times the lighting is switched on. It
is adjusted to 1–2 hours. A longer time means that the lighting is
switched on fewer times each day. Longer time = less wear to the
cathodes of uorescent tubes.
Adjust the delay for detector(s) to 1–2 minutes or slightly
longer to suit wishes. This time determines how long the lighting
remains at the higher level after presence was last detected. This
time should therefore be kept as short as possible.
It is very important that the settings for the installation are
documented and that this is kept as a record that adjustment
has been carried out according to the instructions. A form for
documenting settings can be found in the “Energy-saving
detection technology” handbook or at www.extronic.se/narvaro/
en/manuals/.
Light sensor (white). When a light sensor is connected it should
be adjusted so that it prevents the lighting from being switched
on when there is sufcient natural light.
Dimmer rate (“Soft Dim”, green). Should be set so that ramping
up takes place at the required rate. The ramp down rate is xed
at around 20 seconds. A good base setting is to adjust the
potentiometer to the one o’clock position.
Fluorescent tube burn-in. New uorescent tubes should be
burned in to deliver their rated performance. Burn-in entails
operating the light ttings at 100 per cent power for 100 hours.
There is a button on the circuit board that starts the burn-in
process for uorescent tubes:
A single press turns on the uorescent tubes at 100% for •
100 hours.
Pressing again interrupts the burn-in process.•
During the burn-in process the lighting can be switched on or off
and dimmed manually.

Optional equipment
PD-2200 presence detector
Order no. 13140,
PD-2200 is a passive IR detector intended
for presence detection. The electronics and
software in the microprocessor of the PD-2200
have been specially designed for presence
detection. There is a lens library consisting of
41 lenses. The number 15 standard lens gives
a detection area of 41 m x 41 m.
EXE-2000rectier
Order no. 18108,
A 13.65 VDC (12 VDC) rectier for mounting on
a DIN rack that ts a standard enclosure and has
a 1.5 A current limit and short-circuit protection.
LS-10 light sensor
Order no. 13100E,
Light sensor for connecting to NV-2T, etc. The light
sensor monitors the light level in the premises.
AD-500/600 detector
Order no. 13095/13091,
AD500/600 are acoustic presence detectors
for lighting control.
These detectors detect presence by listening
for sounds in two different frequency ranges
and analysing the signals. The lighting is
switched on by inaudible low-frequency
sound that is generated when a door is opened. The lighting is
kept on as long as higher frequency sound such as footsteps and
speech are detected.
AD-300 acoustic auxiliary detector
Order no. 13126,
AD-300 is an auxiliary acoustic detector for
controlling lighting in combination with an IR
detector. The purpose of the detector is to switch
on lighting when someone enters the premises by
detecting the infrasound (low-frequency sound)
that is generated when a door is opened. This ensures that lighting
is switched on in areas that the IR detector cannot “see”, such as
concealed doorways, making the system more convenient.
AD-350 acoustic auxiliary detector
Order no. 13130,
AD-350 is an auxiliary acoustic detector intended
for controlling lighting in combination with an IR
detector. It listens solely to a limited frequency
range between 3 and 7 kHz and switches on the
lighting (or keeps it switched on) when sound is
detected in this range, before the IR detector detects presence. The
AD-350 is often used to supplement IR detectors, to ensure that
lighting remains on when people are present.
