ExplosionProof MotionSensor InstructionManual
Thank you for your purchase of the EXP-DNMS-N4X-AT-HV Motion Sensor, the following instructions are intended for
this part number only.
Installation
This unit is easily wall mountedvia integral mounting bracket, which can be adjusted-90° to +30° vertically after
installation. The explosion proof housing provides two 1/2" or 3/4" hub openings locatedon either side of thehousing for
running electrical conductors in a feed through configuration. A bushing seal at each conductor opening prevents
damage to wiring insulation.
This unit is designed to operate on voltages of 120V, 208V, 220V, or 277V AC. Voltage is chosen when ordering. This
motion sensor is suitable for use in environments where combustible dusts and particulates may be present. 1/2" or 3/4"
NPT tapped conduit openings are provided on either of the unit in feed through versions while dead end versions have a
single conduit hub, providing easy and secure connection to main power line supplies.
The EXP-DNMS-N4X-AT-HV operates like a standard on/off light switch. The circuit is normally openwhen 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 theother 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 movingtowards the sensor are detected best.
NOTE: the highfrequency of the output ofthis sensor is <10Mw – that is just one 100th of the transmission
power of a mobile phone or the output ofa microwave oven.

Detection area can be reduced by selecting the combination on the
DIP switches to fit precisely each application.
Refers to the time period the lamp remains at 100% illumination after
no motion detected.
The sensor can be set to only allow the lamp to illuminate below a
defined ambient brightness threshold.
When set to Disable mode, the daylight sensor will switch on the lamp
when motion is detected regardless of ambient light level.
30lux, 50lux,100lux,:twilight operation, 5lux, 15lux: darkness operation only.
By selecting the combination on the DIP switch, sensor data can be precisely set for each specific application.

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
