Description
Partial-ON Option
­­­­­­­­ he PW-311 passive infrared (PIR) dimming wall switch sensor
T
can turn lights OFF and ON based on occupancy and allow the
user to increase or decrease the lighting level. It works with
0-10 VDC dimming drivers and ballasts to control lighting loads
including LEDs.
When set for Automatic-ON operation, the PW-311 typically
comes ON to the last non-zero light level for occupant comfort
and convenience. However, this default setting may be changed
to a fixed light level value of 50%, 75% or 100%. The dimmed
level options (Preset On Level) support new state and federal
energy code requirements.
Operation
The PW-311 installs in a single gang junction box with or
without neutral wiring. Factory default operation is for ManualON, so that users turn lights on only when needed. It uses PIR
technology to detect occupancy. Once the space is vacated
and the time delay elapses, lights automatically turn OFF. DIP
switch settings enable a variety of control options such as
Auto-ON operation, high and low trim, ramp up and fade down
times, power loss mode, smart light level, walk-through and
test modes. Multiple sensors may be used to dim a lighting load
from up to four locations.
Applications
The PW-311 sensor is ideal for enclosed spaces with clear line
of sight of the occupant. Common applications include small
offices, small conference rooms and lunch/break rooms. It
can be used for a two-wire or three-wire installation, either to
work with existing wiring, or to meet recent local or national
electrical code requirements. An easy-to-break plastic tab
covers neutral screw terminals. Once the sensor is connected
to neutral it complies with all codes that restrict current
leakage to ground.
Features
• Neutral Sense™ and optional neutral wiring simplifies 2011
NEC-compliant installation
• Test mode allows quick and easy verification of coverage
• Vandal resistant lens combines precise coverage with
durability
• LED indicates occupancy detection
• Presentation mode may be deactivated to allow Auto-ON
operation after 15 second time delay
• Optional Smart Light Level adapts ambient light hold off
threshold to meet user needs
• Selectable walk-through mode turns lights off three minutes
after the room is initially occupied if no motion is detected
after the first 30 seconds
