Installation
(s. fig. page 3)
The site of installation should
be at least 50 cm from a light
because heat radiated from it
may trigger the sensor unin-
tentionally. To obtain the
specified reach of 12 m, the
sensor should be installed at
a height of approx. 2 m.
Please observe the safety
warnings on page 12.
Installation procedure:
1.
Undo screws on housing
2.
Do not detach wiring from
terminal block, but gently pull
entire terminal assembly, in-
cluding sensor unit
(cylin-
drical section), to remove it.
3.
Hold mounting plate
against wall/ceiling, mark drill
holes, paying attention to
wiring runs concealed in
wall/ceiling. Drill holes, insert
wall plugs (6 mm).
4.
Break open pre-punched
cable entry holes as appro-
priate for concealed
or
surface-mounted
installa-
tion, insert grommets, pierce
and pass cable through.
Note:
For surface-mounted
wiring, it is recommended to
install the swivel mount
(see below). Alternatively, the
unit may be pierced at the
thinner section to pass the
cable through.
5.
Screw mounting plate
to wall.
6a) Connecting the mains
lead
The mains lead consists of a
2-3 phase cable
L
= phase conductor
N
= neutral conductor
PE
= protective-earth
conductor
If you are in any doubt, you
must identify the cables using
a voltage tester; then discon-
nect the power supply again.
The phase
(L)
and neutral
conductor
(N)
are connected
according to terminal assign-
ment. The protective-earth
conductor is connected to
the earth terminal
.
A mains switch for ‘ON’ and
‘OFF’ switching can of
course be installed in the
mains lead.
6b) Connecting the load
supply lead
The load supply lead (e.g.
light) is also a 2 to 3-core
cable which is connected to
terminals
N
and
L’
. The live
conductor must be connect-
ed to the terminal marked
L’
.
Connect the neutral conduc-
tor to the terminal marked
N
together with the neutral con-
ductor of the mains power
supply lead. The protective-
earth conductor is connected
to the earth terminal
.
7.
Once wiring is completed,
insert terminal block together
with sensor unit
into
mounting plate
, fit housing
cover
and secure in place
with fastening screws.
The swivel mount
allows
you to turn the motion detec-
tor horizontally. This provides
additional adjustment for the
detection zone.
1.
Press cupped pieces
out
of swivel mount
provided
with sensor unit.
2.
Hold swivel mount
against wall and mark
drill holes, drill the holes,
insert wall plugs, pass cable
through. Connect as
described in „Installation“.
3.
Pass screws through
cupped pieces
and secure
Installation with swivel mount
swivel mount
in such a
way that the screw head is
positioned on the smooth
side and the domed side
rests against the mounting
plate
(see diagram).
The system can be put into
operation once the sensor
has been connected and
installed. Two setting controls
Switchoff delay
(time setting)
The chosen light ‘ON’ time
can be varied continuously
from approx. 8 sec. to a
maximum of 35 min. The
shortest period, approx.
8 sec., is selected by
turning the control fully
clockwise. The longest
period, approx. 35 mins.
is selected by turning the
control fully anticlockwise.
It is recommended to select
the shortest time for adjust-
ing the detection zone and
for performing the walk test.
Any movement in the detec-
tion zone will reactivate the
time setting.
Twilight setting
(response threshold)
The chosen detector
response threshold can
be adjusted continuously
from approx. 2 lux to 2000
lux. Turning the control
fully clockwise will select
daytime operation at
approx. 2000 lux.
Turned fully anti-clock-wise,
the control is set to dusk-to-
dawn operation at approx.
2 lux. When adjusting the
detection zone and for the
performance test in daylight,
the adjusting screw must be
turned fully clockwise.
Functions
8 sec. – 35 min.
2 – 2000 lux
are provided on the bottom
of the unit.
Reach adjustment
(s. fig. page 4)
Reach can be reduced by
tilting (70°) the sensor.
The sensor can be turned
horizontally through 40°
(only with swivel mount) to
align the detection zone in
exactly the way you require.
The adhesive shrouds
provided may be used to
adjust the sensor‘s detection
angle to suit individual
requirements. This makes
it possible, for example,
to blank out neighbouring
premises from detection or
specifically target paths.
