Coverage Patterns; Button Functions - LEGRAND Wattstopper DW-311-I Installation Instructions Manual

COVERAGE PATTERNS

Coverage testing has been performed according to the NEMA WD 7 guideline.
For best performance, use in spaces not larger than 15' x 12'.
PIR Sensor
The sensor has a two-tiered, multi-cell viewing Fresnel lens with 180 degree
field of view. The red LED on the sensor flashes when the PIR detects motion.
Masking the lens
Opaque adhesive tape is supplied so that sections of the PIR sensor's view
can be masked. This allows you to eliminate coverage in unwanted areas.
Since masking removes bands of coverage, remember to take this into account
when troubleshooting coverage problems.

The Multi-Way capability is available on all models. Sensors can easily be wired together for convenient control of a common load.
When wiring this way, only use DW-311 series sensors. Multi-Way in DW-311 series is not compatible with prior sensor models.
The following principles apply for Multi-Way:
• All units should be on the same phase.
• All units can sense each other's push button events and respond accordingly.
• All units can sense each other's PIR trigger event. The response will be determined by the Light Level setting and/or conditions of
the space of the detecting sensor.
• The time delay for all units is defined by the unit with the smallest time delay.
• All Units can sense each other's dimming events and respond accordingly.
NOTE: Models with v2 cannot be used with non-v2 models for multi-way applications.
Pressing and holding the UP button will ramp the lights up to the maximum value as determined by the High Trim setting. Pressing
and holding the DOWN button will dim the lights down to the minimum value as determined by the Low Trim setting. See Additional
Programming Features for detail on setting the trim.
• Tapping the UP button when the load is OFF sets the load to the last non-zero value.
• Tapping the UP button when the load is ON sets the load to the maximum (high trim) value.
• Tapping the UP button twice when the load is OFF turns the load to its maximum (high trim) value.
• Tapping the DOWN button when the load is ON, turns the load OFF.
ADJUSTING THE SENSOR AND ACCESSING OTHER FEATURES
Remove the wall plate. Remove the button cap by firmly squeezing together
the top sides of the button assembly. Gently pull it away from the unit.
When the adjustments are completed, replace the button cap by inserting
its hinges into the tabs on the main unit and then squeeze the top of the
button while pressing it into the unit. Reinstall the cover plate.
Turning the Load ON (ON Mode)
The relay is programmed for either Auto ON or Manual ON. In either
mode, the load can be turned ON or OFF using the up and down buttons.
Manual ON
With DIP switch 1 in the ON position, the occupant must press the Up
button to turn ON the load. The sensor keeps the load ON until no motion
is detected for the selected time delay. There is a 30 second re-trigger
delay. If occupancy is detected during the delay, the sensor turns the
load back ON. After the re-trigger delay elapses the Up button must be
pressed to turn ON the load.
Auto ON
With DIP switch 1 in the OFF position, the load turns ON and OFF
automatically based on occupancy. There is a 5 second re-trigger delay. If the load is turned OFF manually, the enable/disable setting
for Presentation Mode operation applies. See Presentation Mode / Disable Presentation Mode for details.
