Introduction
The SLDD1000 features an integral daylight sensing
photocell which will automatically switch connected
lights on at dusk and off at dawn.
It incorporates an adjustable operation delay to prevent
mis-operation due to e.g. car headlamps.

Installation
The unit is suitable for connection to a 240 V ac 50Hz
electricity supply. It is suggested that 3-core round
flexible cable of 1sq.mm gauge is used. An internal
switch should be installed to switch the power to the
unit ON & OFF. This allows the sensor to be easily
switched off when not required or for maintenance
purposes.
IMPORTANT
Switch off the electricity at the fuse box by removing the
relevant fuse or switching off the circuit breaker before
proceeding with the installation.
Open the unit by gently prying the “ears” on each side
of the unit. See diagram A. This can be done without a
tool, but if you prefer use a flat blade screwdriver, but
be careful not to damage the clips. They should release
easily. The front cover is hinged at the top, the front
cover will swing open upwards.
Using the unit as a template, drill the holes. Insert the
wall plugs into the holes. See diagram B.
It is recommended that the grommet is pierced with a
screwdriver to ensure a better seal.
Fix the unit to its mounting surface. Do not overtighten
the mounting screws as this could damage the unit. If
using a power screwdriver, use the lowest torque setting.
Remove the cable clamp. See diagram C
Pierce and pass the cables through the grommet. We
recommend you use a screwdriver to pierce the
grommet as this will give a better seal.

on the unit as follows (see connection diagram):
NEUTRAL (Blue) N
EARTH (Green/Yellow)
LIVE (Brown) L
Connect the lighting load cable to the terminal block.

LIVE (Brown) L1
Please note the the N terminals are common.
Ensure that the connections are secure.
Re-attach the cable clamp and secure.

Installation is complete.
Connection Diagram
Testing
Set the adjustment knobs as follows:-
See diagram D.
Dusk setting, fully anti-clockwise (daylight setting)
Time Delay setting fully anti-clockwise (minimum 2 sec)
The Dusk setting determines at which light level the
switch will turn its connected load “ON”
Turning this setting fully anti-clockwise allows you to
test the circuit during daylight.

Connect the unit to the mains and switch power on.
After a short delay, the unit will switch ON. This is
indicated by the red LED see diagram C. Any attached
lights will also illuminate.
Setting up for automatic operation
The DUSK (LUX) control determines the level of
darkness required for the unit to start operating.
The setting is best achieved by the procedure below:
Set the Dusk and Time Delay control knob fully anti-
clockwise. Wait until darkness falls.
When the ambient light level reaches the level of
darkness at which you wish the lamps to become
operative (ie. At dusk), SLOWLY (a small step at a
time) rotate the control in a clockwise direction until a
point is reached where the lamp illuminates. Leave the
control set at this point.
At this position, the unit should become operative at
approximately the same level of darkness each evening.
Observe the operation of the unit. If the unit is starting
to operate too early (ie. when it is quite light), adjust
the control slightly anti-clockwise. If the unit starts to
operate too late (ie. only when it is very dark), adjust
the control slightly clockwise.
Continue to adjust until the unit operates as desired.
The Time Delay setting allows the user to determine at
which time after the required darkness level is reached
the lights will illuminate. This is beneficial in areas
where intermittent light/darkness exposure is possible
ie:- car headlights, or shadows.
Turning the adjustment knob fully anticlockwise will
illuminate the lamps 2 seconds after the lower lux level
is reached.
Turning the adjustment knob fully clockwise will
illuminate the lamps 5 minutes after the lower lux level
is reached. This will eliminate possible on/off
switching due to intermittent light/darkness exposure.

Solution
The level of ambient light in the area may
be too bright to allow operation at the
current DUSK setting. During the hours of
darkness first turn the Time Delay knob to
minimum then adjust the DUSK control
slowly clockwise until the lamp illuminates.
Refer to previous section for more details.
Adjust the setting anti-clockwise to lower
the level of ambient light required for
activation.
