.../...4E and .../...6D:
Connections as above, but in addition the 9W TC-E or 18W TC-L model has its own switch connection. The
light fitting's live wire can be connected to either different phases or the same phase together with the 18W
TC-L model, and either through a switch or such that it is continually connected to power supply (see pic. 1c).
WHEN MEASURING THE INSULATION RESISTANCE, THE POWER MUST BE SWITCED OFF. THE NEUTRAL
AND THE LIVE WIRES MUST BE CONNECTED TOGETHER. THE INSULATION RESISTANCE IS MEASURED
BETWEEN THE PROTECTION WIRE AND THE CONNECTION OF THE NEUTRAL AND THE LIVE WIRES. TO
ENSURE PROPER OPERATION THE EARTH WIRE CONNECTION MUST BE SECURED.
3. DETECTION AREA
The PIR sensor's detection area is 360° horizontally and approx. 135° vertically, as shown in pic. 2. The
detection distance depends on the height at which the sensor is mounted and the angle at which move-
ment occurs.
The sensor reacts most sensitively when movement occurs across its field of view and least sensitively when
movement occurs directly towards the sensor of the light fitting. The detection distance may vary accord-
ing to the ambient temperature. It may also vary if the distance between the lens attached to the diffuser
and the sensor in the light fitting has altered. The detection area can be restricted to a desired direction by
partially covering off the lens with the non-transparent tape supplied in the kit.
4. OPERATION
After connection to the power supply, or after a power failure, the PIR sensor will be functional approx. 10
seconds after its automatic self-test. If movement is detected by the PIR sensor after it is functional, it will
turn on the light fitting if conditions are dusk enough (see LUX adjustment). The light fitting will switch off
when the movement stops and the delay time set on the TIME potentiometer has been reached.
The PIR sensor's green LED glows dimly when the sensor is ready to operate but has not been triggered.
When the sensor is triggered by movement the red LED comes on. If the device detects a fault during the
self-test, after connection to the power supply, the red LED flashes alternately brightly and dimly.
5. ADJUSTMENTS
Before any adjustments can be made the diffuser must be removed. Adjustments should be made using
a small screwdriver, the appropriate potentiometer being gently turned. The marked settings are only an
approximate guide and are not precise (see pic. 3). The settings made at the factory are the TIME horizontal
setting (approx. 1 minute), the LUX medium setting (approx. 100 lx) and the SENS horizontal setting (set
to the max. side).

SENS
The SENS potentiometer permits adjustment of the sensitivity of the
sensor to movement. Note that also the sensor's detection area may be altered.
TEST Turning the SENS potentiometer moves the sensor in the test mode. This
test mode lasts for 3 minutes from the last adjustment of the SENS potentiometer.
In the test mode the green and red LEDs flash alternately. In the test mode the
detection area can be tested by walking across in front of the sensor, causing the
light fitting to switch on in response to the movement for approx. 5 seconds. The
sensitivity during a test will be at the level indicated on the SENS potentiometer.
After switch off there is a delay of approx. 2 seconds before switching on again.
