1. INTRODUCTION
ENG
The light fi tting is designed for ceiling mounting. It can also be mounted on a wall at
a height of at least 1.7 m. The light will switch on automatically when a heat-emitting object
such as a person comes into its sensor's detection area. When choosing the place of installa-
tion avoid all interfering sources within the detection area that might affect the light fi tting's
operation, such as ventilating grates, warm air fans, refl ective glass or wall surfaces, or other
light fi ttings that are too close to the PIR (Passive Infra Red) sensor. Sunlight may also trigger
the device if it appears suddenly within the sensor's detection area during cloudy weather.
THE LIGHT FITTING SHOULD ONLY BE INSTALLED BY A PERSON WITH THE REQUISITE
KNOWLEDGE AND SKILLS. USE ONLY THE BULB TYPE AND WATTAGE INDICATED
ON THE LIGHT FITTING. THE PIR SENSOR CANNOT CONTROL AN EXTERNAL LOAD
EXCEEDING THE PERMITTED LEVEL! TURN OFF THE POWER BEFORE MOUNTING OR
REPAIRING THE UNIT. KEEP THESE INSTALLATION INSTRUCTIONS FOR USE WHEN
MOUNTING OR SERVICING THE UNIT AT A FUTURE DATE.
Maximum external load: 400VA fl uorescent lamps or 400W incandescent lamps.
On the AVD/AVR...6D types a minimal illumination level (approx.10%) has already
been set. This means that the light glows dimly when the PIR sensor is not
activated. The light intensity increases to 100% when the PIR sensor responds to an
object.
2. CONNECTION, see pic. 1
Connect the live wire to terminal L, the neutral wire to terminal N and the protection wire (yellow/
green striped) to terminal
pic. 1 a). The light fi tting's PIR sensor can be by-passed with a switch. This also enables the light
fi tting to be switched on continuously. Connect the switch between terminals L and
b). Light fi ttings can be connected in parallel.
.../...4E and .../...6D:
Connections as above, but in addition the 9W TC-E or 18W TC-L model has its own switch con-
nection. The light fi tting'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 movement occurs.
The sensor reacts most sensitively when movement occurs across its fi eld of view and least sensitively
when movement occurs directly towards the sensor of the light fi tting.
