MOTION SENSOR
The
SLEDB-110V-MS-20C
operates like a standard on/off light switch.
The circuit is normally open when no motion is present. Once motion is
detected, the internal switch changes to a closed circuit, allowing voltage
to pass through the sensor and power the device(s) at the other end.
The sensor is an active motion detector; it emits high-frequency electro-
magnetic waves (5.8GHz) and receives their echo. The sensor detects
the change in echo from even the slightest movement in its detection
zone. A microprocessor then triggers the “switch light ON” command.
Detection is possible through doors, panes of glass or thin walls.
IMPORTANT:
persons or objects moving towards the sensor are
detected best.
NOTE:
the high frequency of the output of this sensor is
<10Mw – that is just one 100th of the transmission power of a mobile
phone or the output of a microwave oven.
Malfunction
Cause
Remedy
The load will not work
- wrong light control setting selected
- load faulty
- mains switch OFF
- adjust setting
- change load
- switch ON
The load is always working
- continuous movement in the
detection zone
- check zone setting
Load works without and identifiable
movement
- sensor is not mounted for detecting
movement reliably
- movement occurred, but not
identified by the sensor (movement
behind a wall, movement of small
object in immediate vicinity etc.)
- securely mount enclosure
- check zone setting
The load will not work despite
movement
-rapid movements are being
suppressed to minimize
malfunctioning or the detection zone
you have set is too small
-check zone setting
