Operation - ensto AVR 400.0184E Bedienungsanleitung

The detection distance may vary according to the ambient temperature. It may also vary if the
distance between the lens attached to the diffuser and the sensor in the light fi tting 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 func-
tional approx. 5 seconds after its automatic self-test. If movement is detected by the PIR
sensor after it is functional, it will turn on the light fi tting if conditions are dusk enough (see
LUX adjustment). The light fi tting 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
fl ashes 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. 3 minutes), 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.

walking across in front of the sensor, causing the light fi tting 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.
LUX The PIR sensor always reacts if the illumination is lower than
the operating threshold set on the potentiometer (LUX setting). If the
LUX potentiometer is turned so that a dim LED (red or green) becomes
brighter, the sensor goes into the illumination level setting mode.
