MOVEMENT SENSOR 360°(CEILING MOUNTING)
T 76 251
Technical Manual
Toyama Movement sensors are intelligent lighting control energy saving sensitivity detectors. Movement
sensors use Passive infrared (PIR) sensor to detect the human movement and make corresponding triggering of
loads, say lights. Usage of SMD components not only ensures reliability but also makes the product highly
compact for its functionality and features. Wide operating voltage range of the Movement sensors makes it
operational across countries from North America having 127V supply to European countries with 230V supply
without any field setting. The device is incorporated with the adjustable inbuilt timer to switch OFF the load when
there is no human movement. The device is also incorporated with Lux detector.
Applications: Movement sensors can be installed in
•Office /Hotel corridors.
•Stair cases/Passage.
•Stores, Classrooms.
•Common fresh rooms.

Please read the instructions before installing!
•Movement sensors should be preferably installed by a Toyama trained Installer (electrician).
•Ensure wires are properly connected with reference to phase, neutral and load.
•Concentrated Light from IR emitting fluorescent lamps should not fall on the sensor window, which
may disturb the sensing operations. As such ensure a minimum distance of around 3 meters between
the florescent lamp and the movement sensor.
•Install the movement sensor only at the specified height
•Install the movement sensor in such a way that the detection range is angled across the movement.
•Use only transformers/Ballast made to IEC or equivalent standards by manufacturers of repute.
•If required connect 2.2uF/440V AC Fan Capacitor across CFL with electronic ballasts to avoid blinking
of lamps when it is OFF.
•Connect upto specified wattage of load only. For higher loads suitable rated contactor of reputed make
can be used.
•Hindrance / moving object should not hide the detection window.
•Avoid installing in Bathrooms. Make sure air conditioners, central heating, etc.do not cloud IR window.
Installation Steps:
1. Turn OFF power through a switch or MCB.
2. Remove the top cover from the sensor by rotating it in anti-clock wise direction.
3. Connect the movement sensor as per the wiring diagram shown below.
4. Mount the sensor on the selected position with the screws.
5. Place the top cover on the sensor and turn it clockwise to lock.
6. Turn ON the power.

OPERATION:
♦The power and movement detection indication: The LED will flash once every 4 seconds after
power ON of the unit, and will flash every 2 seconds when the units detects the movement.
♦Detection field: The detection field is made up of up and down, left and right service field. (See
the following diagram). But it has the relation ship between the sensitivity and the orientation of
moving. Detection distance may vary according to the installation position and detection field.
♦Time-delay adjustment: The timer knob can be set according to the customer needs. The
minimum is 30 sec. and the maximum is 450 sec delay OFF.
♦Identifies day and night automatically: When the trimmer knob is turned towards SUN Position
(max), it will switch ON lights both in day and night. When turned towards MOON position (min),
the sensor will operate only at night (less than 10LUX ambient light)
Correct Moving Orientation Incorrect Moving Orientation
At a distance closer to sensor the detection motion speed can
be minimum and vice versa

TROUBLE SHOOTING:
Symptom Possible cause Remedies
Lights do not ON
•Light(s) burned out.
•Breaker is OFF or tripped.
•Wiring error
•Lux level adjuster (Photo) may
be in moon mode.
•Replace the bulbs
•Switch ON the breaker.
•Check and correct the connections
•Turn the lux level adjuster (photo)
fully clockwise.
Sensitivity is poor
•Installation height may be high.
•The sensitivity level adjuster
may be low side.
•Incorrect moving orientation
•Obstruction in front of sensor
window
•Install at recommended height.
•Turn the sensitivity level adjuster
to high side.
•Correct moving orientation
•Remove the obstruction in front of
the window
