WARNING!
The ATEX rating labels must be fitted at all times, if damaged they must be replaced
immediately or the sensor must be removed from service and the hazardous area.
WARNING!
Changes to the design and modifications to the equipment are not permitted.
WARNING!
Never operate the sensor outside its rated voltage, current and power as indicated in the
specification or the safety of the unit may be impaired.
CAUTION
Ensure that the sensor is mounted safely and securely using suitable fixings.

Technical Specification
The sensor is an active motion detector which emits a high-frequency electromagnetic wave and receives its echo. The
sensor detects the change in echo from movement in its detection zone. A microprocessor then triggers the ON
command. Detection is possible through doors, panels of glass and thin walls.
