DESCRIPTION AND OPERATION
The HB350W-L3 occupancy sensors is designed for automatic lighting control in high bay wet location applications. The sensor is
modular and are made up of two parts, a Sensor Module (HB350W) and a Lens (L3). The sensor uses a set of DIP switches to set the
time delay and PIR sensitivity as explained on page 2. The HB350W-L3 provides a single load controlling relay.
INSTALLATION OVERVIEW
1. Review the ADJUSTMENTS section and complete any
necessary DIP switch setting changes.
2. Mount the sensor so the lens is below the edge of the fixture
and away from the lamps. Heat from the lamps could affect
the sensor operation.
Make sure that you have the appropriate accessories for the
sensor mounting configuration. (See Mounting Options.)
3. Assemble any necessary mounting accessories and attach
them to the sensor module. Make sure that the flying leads
from the sensor module cable are accessible inside the
fixture.
4. Connect the line voltage and load wires to the sensor leads
as shown in the applicable Wiring Diagram for the sensor
module.
• Do not allow bare wire to show.
• Make sure all connections are secure.
• Check all gaskets for watertight fit.
5. Check sensor operation. Refer to the TESTING section.
6. Attach the Lens to the HB350W-L3 as shown in the sensor
assembly drawing.

PIR Sensitivity (Switches 1-2)
The factory setting (Normal) is suitable for most applications, but
it may be necessary to adjust the PIR sensitivity if there is any
environmental interference causing false triggers or if sensitivity
needs to be increased for your particular application. Use DIP
switches 1 & 2 to adjust sensitivity.

ADJUSTMENTS
The sensor is pre-set at the factory to meet the requirements of
most applications. Review this section if your application requires
changing factory pre-sets.
Sensor factory pre-sets are as follows (default settings are bold):
Override (Switch 8)
The override disables the occupancy control feature of the
HB350W-L3 sensor module. When occupancy control is disabled,
the load remains ON as long as the sensor is powered.

COVERAGE AREA
The coverage area is determined by the lens. The lenses are interchangeable with any HB350W series sensor module.
For a description of lens coverage patterns, see the LENS COVERAGE section in this instruction sheet.

MOUNTING OPTIONS
As shown in the illustration, the HB350W-L3 can be attached
directly to a watertight fixture or junction box that is equipped
with a threaded nipple. The center of the threaded nipple
should be no more than approximately one inch (1”) from the
bottom of the fixture to avoid blocking the sensor’s view.
The HBEM3W extender module allows attaching the sensor to
the side of the fixture so that the lens can be positioned below
the bottom edge of the fixture. The wiring cable is threaded
through it and into the fixture for connection. The two sides of
the HBEM3W snap together to protect the cable.
The extender housing is not watertight, but the inner flange
rings on the chase nipple and the HB350W-L3 housing fit into
grooved rubber rings on the the cable. This keeps moisture
from entering the fixture and sensor at those locations.

LENS COVERAGE
The HB350W-L3 has a multi-cell, multi-tier Fresnel lens with a 360° view. Coverages shown in the diagrams are maximum. They
represent coverage for full-step walking motion, with no barriers or obstacles. Temperature variations may affect coverages and sensor
detection.
IMPORTANT START-UP INFORMATION
A 60-second start-up period occurs during initial installation and
after a power failure of 5 minutes or more. After applying power to
the sensor wait at least 60 seconds for the sensor to begin detecting
occupancy and the load to turn ON. It may turn ON during the start-
up period, depending on the state of the relay when power was off.
• If the sensor detects occupancy during the start-up, when the
load turns ON it stays ON as long as the sensor continues to
detect motion, plus the Time Delay.
• If no occupancy is detected during the 60-second start-up, the
load may come on anyway during the start-up. If no occupancy
is detected by the time the start-up is complete, the relay opens
and the load turns OFF.

TESTING
1. When mounting and wiring are complete, cover up the sensor to prevent it from detecting motion.
2. Apply power to the sensor and light fixture. Lights may turn ON during the 60-second start-up period.
3. Wait for the start-up period to end. For the next 1 to 2 minutes the sensor runs through a self-diagnostic routine.
4. If the load came on during the start-up period, wait for it to turn OFF, indicating the self diagnostic routine is complete.
5. Uncover the sensor and confirm that when the sensor detects motion, it’s red LED blinks and the light turns ON.
6. Disconnect power.
7. Attach the lens as shown in the assembly drawing. Tighten securely to ensure that seal is complete.

TROUBLESHOOTING
To confirm proper operation, review the Start-Up and Testing information.
Red LED on sensor module does not blink:
Check for proper sensor wire connections and make sure they are tightly secured.
Red LED blinks but lights do not turn ON:
1. Make sure that power to the sensor has been ON continuously for at least one minute, then
a. Turn OFF power to the sensor.
The relay will close.
b. Turn ON power to the sensor.
The load should come ON. If not, continue with step 2.
2. Check power connections to the load.
3. Check all sensor wire connections. Verify the load wire is tightly secured.
Lights will not turn OFF:
1. If there is no motion from people or equipment in the sensor’s view but the red LED blinks, look for any nearby source of infrared
energy (heat) in motion, such as turbulent air from a heating or cooling supply, or other sources such as heat from the fluorescent
lamps in the fixture.
• Mount the sensor so that it’s lens is below the edge of the fixture and does not directly view the lamps.
• Divert the air supply away from the sensor, or move the sensor.
2. Verify time delay set in switches 3-7. The time delay can be set from 15 seconds to 30 minutes. Ensure that the time delay is set to
the desired delay and that there is no movement within the sensor’s view for that time period.
3. Check Override DIP switch setting. If switch 8 is ON, the PIR is overridden. Occupancy control functions are overridden and the
load stays ON.
4. Check sensor wire connections. Verify that all connections are complete.
